ZC Help

part 1: This is a 2 part question. I have 89 ZC with 85,000 on it and was wondering what I could do 2 give it alittle extra power, I have the intake and the 2.5 inch exhaust piping from cat back someone was saying I should get headers but don't know what a could brand would be and how much they cost.

Part 2: what is a better tranny the Zc or the SI cuz I have new SI tranny and clutch.

part 1: DC makes a nice header at a good price to complement your intake and exhaust but you should also upgrade your cat to a more free flowing unit(Magnaflow 100 bucks partsource).
Part 2: Pretty much the same tranny although You might have one of the rare LSD equiped ZC trannies and if thats the case then I'd use it over the SI tranny.

zc tranny has better acceleration (quicker gears), but the top speed issue ie when your on the highway, you'll be at a very high rmp is a dissadvantage. i used the si trans and my 1/4 mile times were worse than when i had my si motor.. still can't figure that one out. i've been told that its probably my ecu cuz i'm still using the si (pm6) ecu.

You can turbo it cheap! or spend some cash and get some headwork done.

Yes. Mr. Death You need to swap your ECU when u change engine. Wrong ECU will make your car run different. This guy i know has a CRX with a zc and a Si stock ECU on his crx Si. The car runs a little different.

I have a zc motor on my car and when i go around 180km it rev around 5900rpm. I dunno if that's consider high or not, but that's what my reading says.
