When you say GT25's make more power. Have you seen this on a R33 gts-t? If so what power? I have had a lot of sujestions but would like to have people who have actually done what they have sujested and give actual results.
I guess now I would like to know what to expect from a 2540 which are reasonably cheap 2nd hand. Or for a R33 should I go for say 2835. Would there be more lag etc. etc.
This is with all standard mods ECU, exhaust, fuel pump, blah blah.
Thanks all!!
