I just wanna no what mod what give me the biggest gains for my setup. I currently have a crx si with a dohc zc swap. Have cai, plugs and wires, gutted cat, flowthrough glassback muffler. Just want a mod that increase hp like 8-15 or something for fairly cheap. Ive seen a header on ebay for like 200 bucks. ope you can have links to ebay and some help. Dont want boost or nitrous

Thanks

 

the ebay headers like the SS Autochrome are an improvement, but my suggestion would be either a Bisi header, or cams. The cams will be more cost effective, but you'll need a good header to make the most of them. The Bisi header is supposed to be the ish, if you can deal w/o AC that is. If I were you, I'd start w/ a decent header setup, at least get a DC. If you are low budget try to find a used DC header for an 89 Teg, and then find a used header for an 88-00 civic. I say this b/c the Teg upper portion mates to teh ZC head w/o port matching, but the collecor won't fit the oil pan, so you need the civic collector to fit properly. If you want Cams you'll need regrinds of stock cams. I have a set of DOHC ZC cams that I may be persuaded to sell for the right price. IM if interested. HTH

EDIT: sorry for the shameless attempt to sell parts

 

ya that ss autochrome is the dealer im talking about. Very cheap. Wood I get descent gains with it?

 

I can't say for sure on teh ZC, I asume so. I have one on my ZC b/c I had it on my A6 & I only received the upper 1/2 of the stock ZC manifold w/ my sawp, so my ZC has always had it. I did notice decent gains on the A6, but honestly I have no reference to other headers on either motor. Based on R&D & others reviews I would suggest saving more & finding a better header. If you really want that header, I'm sure that it will help a little.
