alrite i mite be able to find some people but incase i cant how do i determine where to notch the pistons

Liquid_02

Gonna have to ask someone else on that one, I've never done it, and I would never do it myself, I'd take it to my local engine re-builder for that part, so much you can screw up

ih8chevy

AODE whats his name said that hes done it a few times and it was really simple..... not sure how complicated it is though.

ih8chevy

real quick i saw a mag article that showed the heads on a stock 91 block make 400 hp but i want to kno what comp should i convert too

Liquid_02

Well your car has a Speed Density sensor, which limits the mods you can do, in order to get that, you'd have to switch over to MAF and an A9L computer (assuming your car's a 5-speed that is)

ih8chevy

it is so should i get the 93 comp my friend has one a drunk driver hit him and his car is totaled so will his comp do its a gt 5 speed

Liquid_02

hmmm I think the 93's had a different computer, Starts with a "C" I think but check it out, if it says A9L... yoink it. Also, you have to change a little bit of wiring to convert it as well, as well as get a MAF sensor. It's a fairly involved conversion

You dont HAVE to switch but it would make things alot easier on yourself if you did.

Also, i h8chevy, your compression ration really depends. It depends on what kind of fuel you want to run and it depends on what you want to do with your car. If you want to go NA you can go something in the 11's and try to still keep it on pump gas and if you want to go with a SC/turbo you can try to get it into the 8's.
