I have a zc motor in my 91 crx, with just an intake stock si manifold, exhaust w/ test pipe, i wanna drop just a few more tenths or want just a little more hp. what is the best mod/thing i can do for $200 or something i can do that doesnt cost anything any adjustments? header, pullies...plugs, wires, feul injectors? whats the best thing to do?

 

ADD VTECH.

but seriously, I think your best investment would be a header.

 

yea, i was thinking the same thing

 

header maybe, but honestly i dont see you getting a whole lot of gain from a 200 dllr header. just get some juice
