I am going to get a manual EL XR8 very soon and I want to get some more power from it. I was thinking about a Trickflow manifold, cam, Difilippo exhaust, cold air, 3.9 gears and an ecu upgrade. What do you guys think about this kind of setup and please post any comments on what brands to go for etc etc. Cheers for any advice.
I know you can get a set of AU XR8 GT40P's from Herrods for $1100 complete. Way better flow than standard.
If your planning to do cam, do the MAF and injectors too then when you do aftermarket chip it will work to its best potential. Correct me if I'm wrong.
How do the later model heads flow compared to the early ones? I've got a set from 69' that flow 217cfm intake and 147 exhuast. Have they improved exhuast flow over the years, or do you need to go aftermarket?
id just get the el heads ported and worked on...at least you know they're in good nic rather than buying someone elses? And they're new once its done.
camshaft and extractors make a lot of difference also..
