Pre-Owned. I thought, "Ok, it's just not gonna happen" and backed it into the garage for the last time, probably after several more stalls.Arron Johnson in his excellent and must see 'Power Building Videos' series at http://www.enginevideos.com describes fuel puddling like the water vapour in the shower only forming droplets on the mirror, as it's smoother than the walls etc. Together we can and will change the world for the better. and even put it in gear without stalling. over the last 14 years since I owned a 1988 Jimmy 2.8L and was forced to sell it at a 50% loss in 11 months due to my employer going broke. Email alerts available. I paid £2600 (US$5000 at the time) but I'll have spent atleast that much on restoration (and tools!) I could link hundreds of sites and videos etc. Manufactured in 1991 by GMC, the Syclone led to the the similarly powered 1992-1993 GMC Typhoon SUV. Smoking during startup and then going away is usually caused by bad valve stem seal wear but if it smokes on throttle too, it's more like blow by past the rings or unburnt fuel, which is brown, as opposed to blue oil smoke.The gearbox seems fine but I have yet to drive the truck further than in and out of my garage a few times, as it would stall easily when shifted into gear but pulled strongly when it wanted to.By the way, three spark plugs were not even hand tight, which didn't help matters. They can 'see' eachother no 'matter' where they are. I was trying to achieve a straight line but there's a ramp down to the injector which follows the outside profile. Donations are most welcome!Go on, it's for a very good cause ;-)More pages later with pics of progress and thanks for taking so much of your time for looking and pop back soon for more porting photos around March/April '09.

There's more than one way to skin a cat, as they say around here. Fast & Free Shipping! ), double sized ATR air to water intercooler via an additional very nice air to air 1000hp rated intercooler by XSPOWER (will start without it to compare performance) and all my insane porting work etc. Add to Favorites More. ;-) and I'll be posting a few pages of photos, before and after as I go, again for my own records if nothing else, as proof of the work done to the engine and to give me a place to put my thoughts down while I remember them.I'm rather prone to spontaneous inspiration and every time I edit this page it grows by leaps and bounds!Now, being English and very critically minded and fussy, (I'm a Joiner/furniture maker 55 hours a week so I have to be), this page is for those with an eye for detail and as we all know, that's where 'The Devil' is. The relative domination and capture into it's magnetic field of a more massive body over a body of lower atomic mass.You can argue the mathematical details but effectively, Planets and even Galaxies are just like atoms, only larger clusters of sub-particles. I had the timing just right so I could start it (yes, second time!) and there's really no need for it.A stock sized Corteco gasket is bolted on but doesn't have the necessary width to properly cover the runner roof, once cut to the same height. I'll be expecting over 400hp at a gallop with the current Mitsubishi 20G turbo (your experience, anyone? There was a strong hissing coming from the distributor area so I knew it had to be there somewhere!I even saw oil dripping onto the intake valve on No.1 cylinder when I rotated the engine with the intake manifold off. From United States. This is a rare find!!!!! but it's way off topic and you know where to look. To me, this says the truck was raced in it's infancy and wrecked the original gearbox and could do it again, so I found a good looking company called http://www.BowtieOverdrives.com and they do an up to 600hp 700R4 unit for 'only' around $1500 plus $350 to England. BTW, don't bother removing the areas I have above as it's actually counterproductive, unless you're going all the way like me and blending it into the manifold by welding material where necessary to create a better flow and to repair some corners that I squared out too much with the B&D Powerfile. Some may have noticed the quality of this car. 1993 GMC Typhoon The GMC Typhoon is a high-performance SUV, produced from 1991 to 1993 by GMC. Located in Winchendon, Massachusetts, this Sierra Grande is now offered on a clean Massachusetts title in the seller's name. My LB4's show clean patches here.A sidenote about 'fuel puddling' apparently caused by overly polished intake runners, while I'm on the subject............The way I see it, (and you can too in the video a bit further down), the valve atomises the liquid fuel on opening, and as fuel gets injected before the valve opens, it will collect for a split second anyway - and better that it ALL flows easily into the chamber than getting stuck in all the scratches (however small) which also quickly attract coke deposits, soaking up more and more fuel with use. Three heads are better than one! You can usually twist them once they're doing that. Description for GMC Typhoon 1991: Syclone #225. There's a 'CPC' number stamped on the shaft but I don't know who made it. They also angle the injectors better while they're at it. Feb '09 update for Typhoon 0117 Restoration. (Don't worry Ian, by the time I find out the running costs, you will be welcome back to it.

The car was built in the Van Nuys, California plant and spent its entire life in California until being relocated to Arizona and hasreceived a full restoration under current ownership. You can never have too many thoughts in your head - (voices maybe) - and words are just thoughts expressed, right?As you can tell, I have lots of those, about lots of subjects.Now, you won't find any unintentional smelling pistakes or typos (and God knows I've tried) so if you're really annoyed by poor spelling and no punctuation etc. On the left, you're looking more directly down the middle, from a slightly lower angle. The Syclone was introduced first, for 1991… They are all open to outside influence, all of the time. The 1991 GMC Syclone is one of the coolest trucks ever built. I drilled and tapped the heads but the water jacket is breached and care needs to be taken to seal the bolt threads on two holes, one in each head.I will post photos sometime of the fuel/air path through the LB4 heads as indicated by the clean patches left after running some Wynn's injector cleaner through the engine before dismantling. Especially with tinted rear windows.I still have some other laser printouts from TheDupontRegistry.com and I kept a general eye on prices over the years but kinda forgot about them while I drove a couple of Supras but 18 months ago, this truck came along at the right price. You're probably already aware of http://www.syty.net/ and similar pages. so I just hope the gearbox holds out but I'll be adding a seperate B&M trans cooler with fan and pod gauge to keep an eye on temps. Infact, the runner floor is curved anyway so it's not even desirable. To help avoid this, I would absolutely recommend Wynn's injector cleaner though. Maybe they're all like this but what's wrong with a key and nut? With just shy of 4,700 units made, getting your hands on a Typhoon isn t easy. Compared to the Sun, the Earth must therefore have a net weaker field (being of a net lower atomic mass) and so it is attracted to the Sun, despite being of no apparent charge atall, since it's made up of 'stable' molecules, for the most part, that apparently balance eachother out perfectly.The truth is of course, that no molecule is completely stable if you apply the correct frequency of energy to it or bring it into proximity with the right elements, (same thing, since all elements have a characteristic frequency of vibration due to their different composition). 1993 GMC Typhoon The GMC Typhoon is a high-performance SUV, produced from 1991 to 1993 by GMC. Equipment includes Sierra Grandetrim, bucket seats, air conditioning, and power brakes. In my experience, piston rings are never an issue.

The GMC Sonoma-based Syclone and GMC S-15 Jimmy-based Typhoon only lasted from 1991 to 1993, with very limited production. Looks like this year is gonna be a real grind though; I've been putting it off for months since I did this last summer '08 and filled (filed?) Bottom right (above and below) is the runner I showed you earlier.

There's the full range of wear patterns from galling and severe particle embedding to grooves, scratches and tapers. Hmmm, more like K & Ended than K & N and what's this thing covered in orange silicone?As you can see, the poor thing was desperately in need of some heavy duty TLC and I was the one to give it. It turned my truck from running smoky and spraying black soot deposits onto the floor under the exhaust pipe, to running pretty cleanly, after just a blast on the accelerator a few times and letting it idle while I was tweaking the distributor with a timing light gun. VEHICLE TYPE front-engine, all-wheel-drive, 2-passenger, 2-door pickup. Both the GMC Syclone and Typhoon trucks featured a Mitsubishi TD06-17C/8 cm 2 turbocharger and Garrett Water/Air intercooler attached to a 4.3 L LB4 V6 intake manifolds, fuel system, exhaust manifolds, and a 48mm twin-bore throttle body from … You can see a Mustang video on Youtube here: http://www.youtube.com/watch?v=syT3LyO_Q5o&feature=channel_pageThey're the coronal discharge type, i.e. This final-year Typhoon has just 67,000 miles, and wears impressively deep black paint. or don't already know full well or even care, you're certainly not going to read all this and probably didn't make it past the above pictures before moving swiftly on.Sure, there are better Trucks on here (most of them at the moment, infact) but you won't find my level of detailed 'analysis' anywhere else on here. Last time I burnt myself on an engine, the heads were pretty damned hot and also, how the fuel will somehow condense into large droplets at 14.7psi (stock) boost I'll never know. The distributor had to be shifted clockwise 1/6th of a turn to even get it to start.I suspect that the camshaft wasn't degreed properly also, as it looks aftermarket but not particularly tall.The gaskets are all Felpro. I've got this Dynotech (extremely) heavy duty front propshaft on it's way when the owner next passes my town on business. ", you don't know the truth; that nothing really matters - but after a few hundred lifetimes you realise that there is no point living like that and you're gonna keep coming back, (whether you like it or not), so live your life as if you must re-live it until you get it right, (like Groundhog Day). S p o n G N s o r e X d R R P 7 S I. Here's the beginning stage of my intake porting, showing the amount of material removed, compared to the stock injector bosses on the left. Anyhow, I think they look a lot meaner in black, don't you? Located in Oro Valley, Arizona, this Camaro SS 396 is now offered on a clean Arizona title in the seller's name.

Relatively speaking then, Earth is like the dust that you can see floating around on a sunny day that is pulled toward your T.v. the truck, since there's so much more important stuff to know about, (like 9/11 being an utterly obvious inside job, among other things). Basically, it's an emulator black box that connects to your ECM and allows real-time datalogging and tuning via laptop for around $300.Definitely go there now and bookmark Josh's page for later and/or this one, as I'll be keeping it posted for my own use;http://www.powertuneplus.com/Lots of Datamaster info too ( http://www.ttspowersystems.com/DataMaster.html ) and don't forget to come right back as there are more excellent links for you down the page;Well done and welcome back.

I'm not sure how many of the hits are mine or yours!If you haven't already done so, why not check out Brisk spark plugs,http://www.briskracing.com/home.php and Nology Hotwires http://www.nology.com/hotwork.htmlBrisk tell me that Nology wires work fine with their plugs. Most people buy the yellow top version for serious audio/visual installs as they have a little bit more capacity for deep cycling but the red top has more cranking power for starting and also handles seasonal or occasional use better (I hope!) I mean, how much spark do you really need? I'll be buying new stainless valves once I know the length as it's a shame to seperate the old ones from the LB4's. It was an instant legend. Unfortunately, I have a sun damaged example with blisters on the roof and a partially melted front bumper cover. Gasket matching will be done later and that will be a very precise, 'in situ' job with the heads bolted down and intake bolted on for final finishing. Back in '96 the cheapest price was around $19,000 though you can still pay that much and more for some lower mileage, relatively 'mint' examples. The 1991 Pacific typhoon season has no official bounds; it ran year-round in 1991, but most tropical cyclones tend to form in the northwestern Pacific Ocean between May and November. I think the engine also needed to be flooded a bit before it would fire as carbon deposits soak up some of the fuel.That's why engines run so much better when they're freshly de-coked. ).I've read that a worn out original fuel pump can cause the strange 'second time only starting' phenomenon as pressure doesn't apparently reach the injectors properly the first time. It runs and drives great. Surely people aren't dumbed down to the point of still not spotting that you've spelt 'than' as 'then', or the most common, 'you're' as 'your'. Why can't injectors have a gauze mask to spray the fuel into a vapour? Check your plugs and if there's a ring of brown carbon around the white insulator as it meets the metal body, it's blowing. ), I couldn't hope to buy one. No-one said goalsetting was a quick fix! Interior is in perfect shape. They obviously went ahead and exploded it anyway to find out.Since then there's understandably been a lot of UFO activity around earth. You always get what you wish for, just not always in the form (or condition) that you hoped!This is my current restoration project (unintentional as they always are) but due to the generally cold and damp weather between October and May here in The UK, I have a thousand and one excuses not to spend hours in the garden shed every evening and weekend, so please be patient as it will all be worth it.......eventually.Looking on the bright side, the only limiting factors are time, discipline, the weather and money!What could possibly stop me apart from the occasional global economic collapse? I may end up having to use seperate billet rails to align the injectors, as raising them in the mounts will cause the angle to shift more vertically and to aim them down at the runner floors even more than they already do. I'll probably end up putting a thousand pictures on here as well! This is the PAS story. Definitely used for drag racing very early in it's life. I'll remove a head at a time for blending with the intake bolted to it, exactly as it will be once finished. My Smart is perfect for that, though the AWD would have come in handy with the snow we're currently having but rust is a major problem here because of the road salt so best left in the garage.Now, some bright spark at GM also decided to press fit the power steering pump pulley. The Bilstein's are far and away better build quality (welds, fit, strength etc.) See, that wasn't a mistake.......This, however, definitely was! The Typhoon is a rare machine, with fewer than 5,000 being built between 1991 and 1993. Saint Charles, IL . for those running Ultimate Chips etc. The Stevie Awards, the world's premier business awards recognized Truck in great shape with no rust or cosmetic damage to the body. Red heads are modified stock LB4's with inch and a half double springs and dampers (all removed), stainless valves and hardened retainers/locks. Shop millions of cars from over 21,000 dealers and find the perfect car. (More of a Syclone joke, that one).Speaking of picking things up, I tried lifting this lump and seriously ruptured one of my discs. There's a great ATR L.E.D. Corners and internal surfaces will be later, once I've determined the appropriate transition profile into the manifold, as it affects the amount of material to remove or rather, NOT to remove. You may know of other, even taller ones. According to the Carfax report it had 3782 miles on the clock on December 28th 1991. The result was the GMC Syclone pickup and Typhoon SUV, a pair of seriously quick trucks which proved that Frankenstein’d parts bin specials could be very capable, provided the engineers involved really did their homework. I'm not so sure, however. You bet but it needs a much smoother intake system, free of interruptions to handle it without seriously blowing a gasket!Gaskets blow by the way, due to the mismatches inherent in production intake systems. The Typhoon was based on the 1991 GMC Jimmy. GMC Typhoon in Birmingham, MI 1.00 listings starting at $29,995.00 GMC Typhoon in Cheswick, PA 1.00 listings starting at $29,350.00 GMC Typhoon in Saint Charles, IL 1.00 listings starting at $22,500.00 Всего было построено 4 697 автомобилей GMC Typhoon C $638.65.

Features include pop-up headlightsand an AM/FM radio. I've had cars with much more cylinder wear than this truck (which actually has none but a polish and some ring end scratches) and once the valves are done, they're always like a whole new engine until the valves need re-doing or the exhaust starts blowing.You can get a general feel for the state of an engine's internals by looking at the amount of oil externally...... You'd think it would atleast prevent all that rust! Sound familiar anyone?You might even learn something here, (whether you're new to these trucks or not) or have comments or (polite) suggestions so PLEASE feel free to correct me if you think I've got something wrong and your experience has been different. I'll debate anyone under the table if you think we're all seperated by anything more than a thin veil of illusion. No problem, that'll be $2295 including 4 piece stainless downpipe! 10's anyone? You can't quite see it in the lefthand photo as you're looking straight down the ramp. They probably all work the same. Regarding production, only 2,995 examples were built and only for the 1991 model year. Let me know if you do. I was going to use those but my new ISKY springs are stiffer at stock diameter than the modded double coils on the old heads and machining would be needed for the seals and spring seats. We know it's cliche, but it's the sort of paint you want to dive into and go for a swim. "My sword grows restless - show me the enemy! You'll be in good company.I'll continue by highly recommending an excellent, no-nonsense website I found for all Sy/Ty owners, although the general philosophy applies to all vehicles; that is, get it running properly in stock form before upgrading it with expensive aftermarket components and then do so in the right order.Obviously if you're well funded and experienced, you'll be building from scratch and not have any problems. What you don't want is for the intake charge to be expanding and contracting as it goes, as this will cause pulsing, which may or may not help matters.Now, there is a 'logical' argument that would say that if the valve seat/short turn radius etc. You can clearly see where the mixture is only entering the intake valves at one point as it comes up the ramp and hits the combustion chamber wall opposite the spark plug, from which it must spin around the cylinder at high speed as it's compressed. The gmc typhoon … I promise to return the gesture! It can? During tests by Car and Driver, the Typhoon was capable o... More Info › Some are very well designed but I don't know how yet. Pointless for a SyTy as the stock head ports are too high as it is, or rather, the manifold is WAY too restrictive of the airflow past the injectors. However, after tightening the distributor clamp bolt, it got a few yards and stalled again! The crank and big end bearing wear is severe. You have to remove the cap but it's easier than any other alternative I can come up with. It may not seem like much can get out but trust me, it will make a big difference to the performance. A nice neat white painted line has been applied to the balancer and timing mark bracket/plate at the zero degree line. It's quite exciting to see for the first time though, that someone had the balls to try it and that it does indeed work, as frankly there are stock SyTy's with practically the same times as highly modified trucks when it comes to street performance. The turntable pics are from the Japanese auction before the Ty came here to England. Multi-port maybe but all 3 injectors firing at the same time per head? I can always buy another and start all over again. I guess L35's are somewhere inbetween but are a direct bolt-on replacement, unlike Vortec's, that is, the intake to head bolt pattern, as both are the same fit as stock LB4's on the block with no modifications necessary.Vortec's need to be drilled and tapped for the manifold or the manifold slotted which only gives 4 bolts anyway, as opposed to 6 in the stock manifold. The slightest leak anywhere will ruin compression.Also, always hand lap valves. You need to extend the face another 1/4" beyond that for a good seal, so it looks like the uncut one on the left again, only longer by 4-5mm (3/16" ish).The main difference between the two models of heads is in the shape of the runners down inside and having directly compared the two, (photos to follow), the stock LB4 heads are like very high, flat roofed chambers full of casting bumps and flashing with nothing directing the airflow down into the intake valve bowl except a narrow helical ramp up the back wall of the bowl, (which would be much more appropriately named 'Vortec' than the later heads, as it does indeed create a vortex), whereas the '96 upward Vortec's are much smoother past the pushrods, (although still allowing FAR too much rod clearance at the expense of flow and bench tests may not show an improvement on normally aspirated engines) and much rounder along the roof, curving the air downwards perfectly into the valve bowl, which is why they flow 270cfm @ .50 lift (standard 28 inches pressure) when ported, apparently, compared to 'only' 165cfm for LB4's. Just 2,998 were built; Syclone was a 1991-only proposition. Cranked spanners are available though so I'll try one of those next time for tuning as it's easy to move the timing while removing and replacing the cap and leads if the clamp bolt isn't firm enough while you're tweaking it. I guarantee that someone on there will know the answer. By the way, stock setup aims the fuel jet about an inch into the head runner floor. I just have to get a quarter mile timeslip but that won't be happening any time soon, I can tell you!Might have the gearbox out too for inspection (like I have a clue what to look for) but the driveshaft squeaks when the truck is moved and the cardon joint crosses are dry and rusty. As for stalling in gear, I can only put that down to poor cylinder compression. They create focal points of extreme pressure build up and 'reversion' which at high temperature and pressure, literally tear the gasket apart like a mini-tornado until over time, it finds an exit. Having said that, I've never actually welded aluminum before but using HTS 2000, it should be a doddle right? The GMC Sonoma GT offered less performance but was seen as a companion model. The way it was running though, I couldn't even get the crank timing line in view without stalling the engine! or Best Offer.
