Wow, I sounded retarded in that last post. oh well that's what i get for not sleeping lol. Anyways, would it be worth the time to shave it enough to get the dohc belt to fit?
shaving the block would bring you back down the the 1.8 liter stroke, unless you used the 2 liter crank with a short con rod. You'd still get the benefits, but getting a conrod could be hard for that. If you can do it great, theres nothign wrong with it
And i said that a CA20DET could outrun a SR20DET cause it's true. But yes you're right there is no support for the CA engines. I've been playing around though with my desktop dyno and a CA20DET with ported head and custom grind cam with only 10 psi boost and a good intercooler would estimate 435hp at 10000rpm (yikes!!) but at 8500 rpm its only making 434 hp

Peak torque 306ft-lbs at 6000rpm, but still has low grunt making 122ft-lbs at 2000rpm. Thats only with 10 psi!! do some custom (expensive) internals to handle more boost...20psi...587hp at 7500 rpm and 411ft-lbs at 7500rpm. Only odd thing is it makes the same ft-lbs at 2000rpm regardless of boost, could be the program making up for a little lag??
As to the accuracy of a program like this??? I believe 500hp is very easy with 20psi. And I think we all know you could prolly still build up more boost or better porting, maybe bigger valves....and the turbo used for the numbers is just a Rajay 300B. They don't have modern turbos for some reason
anyhow....i'm done going off a little here. If you do want 500hp though for cheap, then go with sr20det. I'll stick to my love of the 80's
