The current 'project' is an American truck/SUV restoration.
The 4.3L V6 turbocharged GMC Typhoon is the limited edition high performance version of the popular Jimmy SUV, one of which I owned in 1995. That's how I discovered the Typhoon when the W.W.W. was in it's early infancy and wanted one ever since.
My chance came 3 years ago for £2600 but due to poor compression and my overwhelming curiousity to find out what rods were fitted, I fully stripped and cleaned the engine but it needs cylinder honing and the new Pro-Gram billet steel main caps fitted and lots of head work before re-assembly in my new workshop, which is under construction, or will be if it can stop raining long enough!
Stock GMC Typhoons are 280-300hp depending on the truck (or owner!) and go 0-60mph in 5.0-5.3 seconds with the stock Mitsubishi 16G (TD06-17C) turbo. This one was already highly modified but I'll take it quite a bit further while I have the engine apart, since many components need replacing anyway.
It will be fully portmatched, (and I mean perfectly), then valve bowl-blended and cc'd (exactly matched for combustion chamber volume after reworking), with ceramic coated pistons, runners and combustion chambers of the replacement 1996 Vortec heads, 5 angle stainless valve job, 1:6 Comp Cams SS roller rockers and an Isky Racing Cam & springs, all bought and paid for. Other items will be Eagle H-Beam rods, Clevite 'H' series race bearings etc.
Should get it in the 12's with no problems with the Mitsubishi 20G turbo but may 'need' to replace it with something bigger, as it's quite worn.
A stock Typhoon will leave a JDM Supra TT standing in a quarter mile and stay ahead until the last few yards. Official time is 14.1 seconds @95mph terminal velocity; not bad for a stock, factory 3822lb truck.
In The States, these trucks are known as Stoplight Warriors, since nothing else can match their acceleration between trafficlights, except the pickup version, the Syclone. Youtube them!
