bulding motor...need ideas
Basically...
I got a turbo than had fun but now I'm sick of 6psi and want to go faster. I saved up and now itz time to build a motor. I've heard few things on Mike Simons motor (some good and some bad) and am wondering if thatz the best (only?) way to go with if your trying to build your motor? Does the Mike Simon Motor still have the 9000rpm? Is there anyone who can tell me about personal experiences with built F20C? Are there other options than the Mike Simon motor? I have 7Gz to work with and am trying to fit few other things with it so....any advices? comments?

Don't know about cost but if you're going to sleeve it, get new rods/pistons. How about trying to overbore it. I think there are some people running at 89mm, with turbo set up. Personally if I end up rebuilding the engine, I'm going to try to overbore to 90.7 to square up the engine and see about getting back to 9K rpm!
One question I have. COnsidering how well tuned the F20C and the F22C are, if you sleeve it will you lose HP/TQ since I doubt the sleeving will be quite as high quality as the original. Although I'm sure you could pay $$$$ to make it even better.
BTW which engine is that. I see it's a chevy V8 but is it an LS1. I've heard you can fit one in a miata so it should fit in an s2k, but it's kinda sick and wrong

GM fast burn (Vortec) heads have pretty slick combustion. You can make a pretty good valve train with roller tappets and shaft rockers. Fuel injection is on all the new engines. All aluminum and 7 liters.
The question with spending $15-20k on a street S2k motor is why? That money invested in a Porsche or some equivalent car would equal or exceed the acceleration with warranty and no tuning required.
No if you start with a Z06 or Supra TT, and plan to end up with 600-900 hp, that is a different story.
Have you thought of adding a Race Logic traction control system with launch control and WOT shifts. Should help a turbo quite a bit without destroying the car.

Not all Vortec heads have the Fast Burn combustion chamber. Shaft rockers are just for show and don't allow for all the adjustments of the old-school stud rockers. Plus, you can't just swap from a 1.5 to a 1.6 when you have shaft rockers. The true sportsmen stick with stud rockers, as is the case with carburetors. Fuel injection is nice and all, but the only fuel injection I'd put on a Chevy SB is the old Rochester off the '57 Fuelie. I'll stick with my 750 Dominator, thanks.
