I just bought a 1990 civic completley stock with the 1.5 what can i do other than intake and exhaust WITHOUT swapping the motor or any wires. dont wanna go vtec. Can I put a different head on my stock block or anything? Thanks for the help

 

Not to really burst your bubble or anything but unless I'm insanely misinformed there's not going to be much you can do to get some decent power. Best thing you could do is get some nice wheels and suspension work and just enjoy a good looking but slow car.

 

with that motor your kinda sol about the only thing you can do if you dont want to swap motors is slap a turbo on it not sure if that thing can handle much but its an idea and cai and header arent going to give you any power gains
