Hi, I was sent over here by a kind person in another forum who said the answers I seek could be found here. I am a reformed mopar guy, I've been building mopar muscle for many years, but like I told some one else recently, the slant six dusters were starting to get to me in a bad way. I would build a strong engine and smoke some clutch bands. Fix that then decimate a rear end. Fix that then bend or break something else. This time I decided to START on a good platform, a real performance car, and build on that. So, I bought an 84 corvette crossfire car about a week ago. I'd like to upgrade the car in just about every way I can. Being in California I'm somewhat limited on certain things, and the art and experience of tuning a six pack over a purple shaft with a tight LSA isn't going to help me here. So, I humbly submit, I would like to ask some one to share with me some wisdom on how to achieve my goals with this car.
1. What is the most cam I can run with this ECM? I was told a 2040 grind by Crane is the one if I can get the heads to flow and port the intake.
2. Is there a method to choosing a chip/cam combination? How do I learn what to look for and why they work together?
3. Would a cam described as being very strong for a TPI or LT1 also run well in a crossfire? Some of those grinds are described as requiring an upgraded chip, but what chip?
4. Is Renegade the only true performance intake available for crossfire? I have looked for an X-Ram and can't find one, and can't find info on who know's how to port the stock one.
5. Why won't a cat back from an 86 C4 work on an 84? is there a different cat? I would like to upgrade the exhaust but don't want the drone of flowmasters any more, however, I have never run flowmaster's behind a cat before, will the cat mellow the flowmasters out alot?
6. And finally, since the 05125 NOS systems setup for crossfire is no longer in production, is there a way I can run nitrous on this crossfire?
I know this is a long first post, but I am dying to get down to business! I am looking at some world s/r torquer heads today, and am going to get this show on the road! So, thank you in advance, every bit of information I can find on this thing will help me make it into the crossfighter it deserves to be. I am also already looking for a fuel pump upgrade and learning what to do about the idle being so inconsistant
It's not a true lope like an isky mega cam, it's like a vacuum issue or something i suspect. I will fix it.. Thank you, so much, truly. I here grumpyvette is the man to ask about all things C4.
