i got a 85 rx7 5 speed gsl 12a. any info one what i can do to get around 400-500HP with no turbo nos or porting let me kno.

 

hows it goin b!

any particular reason why you don't want to turbo her?

i can't think of much, but you could shed weight, maybe full exhaust with performance headers, uh more efficient intake

boost is really the easiest way to make easy horse power

I'm only 15 no job very little money I'm starting to build 13b for a 12a replacement.
I'm practicing my porting on old housing i plan to do a center plate bridge port. and if i can get good price on turbo stuff then ill hope on it. and down the road bridge is great for nos so maybe 75 shot, but I'm sticking to the Holley no fuel injected stuff
