I have an 2000 Integra Type R (as my user name would suggest) with 90000km (56000mi) on the clock. Could someone please give me some advice on which components I should modify to give me the most bang for $ . I don't want to modify any of the motor's internals. Changing the exhaust is not really an option, I like the way it sounds and removing the cat is illegal in Australia (if a cat back system would give me at least 10 extra hp then I am interested in changing it.) I was thinking of changing the ECU and the air intake initially some advice here would be greatly appreciated...
Thanks.
