The 2.0L doesn't start making the same torque as the 2.3L until 7k+ RPMs. For a race car with weight penalties in mind, and a built motor that can rev, then the 2.0L is the way to go. But when you start taking into consideration drivetrain/syncro wear (from high RPM use), engine wear, drivability, fun factor, area under the curve, I'd take the 2.3L any day for a street car.

Mods for both cars include, buschur intercooler and intercooler piping, full-race manifold with gt-35r, buschur alky kit, 272 cams, stock intake, and throttle body, buschur turbo back exhaust, and aem ems that I tuned.
Only difference in the two are displacement.
Run#11 is from the 2.0L block 28psi pumpgas and alky injection.
Run#12 is the 2.3L stroker again at 28psi with alky injection.
You can see that the stroker spools the turbo about 1500rpms quicker that the 2.0L, but doesn't make as much power up top.

Awesome graph - thanks for doing the comparo.
The 2.0 indeed did make slightly more power but god damn, the driveability and fun factor of driving the 2.3L car far outweighs that extra power of 7000rpm. IN fact, if both did a roll-on race from 4k the stroker would pull much harder and in fact, I dont know if that 2.0s extra power could even make up for it!
Damn it I want a stoker so badly.

I would think that if these cars had ported heads or sheet metal intakes the curves would look alot different. However both these cars had stock intakes, stock heads, stock throttle body, which my have been hurting the flow needed for a 2.3L..... but thats only a guess.

Questions:
1. This is a stroker kit right? Not a 2.4 4g64 block right?
2. Who owns the 2.3 with 35R?
3. What 2.3 kit does he run? Buschur's or AMS'?
I am awestruck by it's similarities to my car's power and curve.

you could easily rev that 2.0 to 9k & have just as wide of a power band than the stroker!!!
also the tq curve on the stroker falls off quick & the 2.0 is nice & flat i kinda like the 2.0 hp & tq curve. the .63 ar probably doesn't help the stroker though.
thanks for posting that up..
