Whats the measurement between the bottom of the oil pan and the bottom of the bell housing?
Also, what clutch and flywheel combo are you using? I assume you are using a sonic or a cruze flywheel and a mustang clutch?
I had these measurements in earlier post of this thread. Centerline of crank output to bottom of pan is 7.5" - centerline of crank output to bottom of tranny bell housing is 6.5" = 1" difference
The stock clutch and flywheel is a dual mass unit that will not hold up to the increased power we will get out of these engines. I would strongly suggest you go with a single mass lightweight flywheel. Major benefits on small turbo motor allowing the engine to rev faster and subsequently spool up the turbo. This is a big improvement for a smaller motor. For the clutch, I would suggest a stage 2 or greater unit which will withstand torque in the 250-300 ft/lbs range and be done with it.
The flywheel I sourced from Clutchmasters. This is a good unit weighing about 11 lbs. I pick one up for $454.20 on-line. It has a replaceable Kevlar insert on the friction surface. It is for a Cruze/Sonic 1.4T.
The clutch will be a custom puck type racing clutch from DXD Racing clutches (a division of South Bend Clutch).
http://www.dxdracingclutches.com/ They can make you whatever you need and are quite familiar with off-road applications. If you just buy a Mustang clutch, it won't fit!!! The I guy that I am dealing with is one of my SCCA friends. He builds clutch systems for Continental GT endurance race cars and off-road racers. I dropped off my aluminum flywheel to him this weekend so he can start building up the clutch with the right parts. He just needed to confirm the spline count on the output shaft form the Isuzu Rodeo T-5R tranny. He is also making me a pilot bushing to fit the T-5 to the Cruze crank. The rest of the system is is standard '98 Isuzu Rodeo throwout bearing and slave cylinder that should work just fine. When he finishes my clutch I will let you know the spec and info if you want a similar one also built to your spec. I also heard Kentucky Clutch make good units to spec. Del Long used them in a few of his D-Mod specials.
