Yeah, it's at the power level of the homologation road car, more or less. It's been mentioned a few times, and is alluded to in the FAQ in the first post. The problem is that there is no firm evidence of exactly what power level the competition version ran at, never mind data for a full torque curve that is needed to make it work in the game. This is the same problem with all of the 450hp+ WRC cars and 700hp+ JGTC cars, I'd just be doing a lot of work to go from one inaccurate number to another. Porting over GT4's S4 engine is one option, but there's nothing to say that it's any more accurate than GT2, as 4 still has a lot of made-up racecar performance figures.
