correct, 00-03 S2000 motor. In 04 they went to 2.2 and thus became the F22c

Ahh.. thanks for the clearification.

Then that make the arguement about its 1.7 hp/ cu in moot since they said that only 12000 are made per year due to extensive hand on on the motor. The Cobalt is a mass produced vehicle.

That makes it moot? So what, do you want to buy more than one or something? FWD makes the Cobalt moot.

Honda publicly admits that they are against using forced induction, but maybe with the introduction of the RDX (turbo K-series) they will come around with their performance models. In the 80s/early 90s before the diesel craze swept Europe, the president of Honda SWORE they would never make a diesel engine because it is against their engine design ethos of small diplacement, high revving motors. Market forces changed that, I think we may be seeing the same here.

Thats comparing apples to oranges. The S2000 is a limited production car vs a mass produced car. The engine is assembled in detal or (extensive hands on, as you put it) vs mass production. Big difference.

well, my buddy kyle on 12psi is making 810...so that's a bit better...all are still way off for real efficient motors...

any type of high revving turbo motor is going to spank a low spinning big engine in any HORSEPOWER ratio...
case and point my senior project 249cc turbo 4-stroke made 6.07 hp/in^3 and it was breathing through a 19mm restrictor per the rule books. Oh yeah, at 19psi.

I'm glad GM has finally caught on to the "import" game...5 years late and still FWD (FTL) but still better late than never.

mmm fun, Cobalt turbo. The way they should have done it the first time around. The game is getting cool, Mazdaspeed3, SRT-4 Caliber, SS Cobalt all around the same power/tq. Good times

I will guarentee that isnt a 346 cu in motor too. More like a 408. I was pushing 12 psi with a T76 on my 347 cu in. Complete fuel system, 6.0 heads and forged motor.. also all on 93 with no meth or anything.

Good job on the project too!
