as some of you may or may not know, i own a aus spec r31 with a rb25det and 5 speed.
its an excellent performing car for the mods it has, and the amount its cost me.
so far has
cooler with custom end tanks to negate the need for a pipe over the radiator
3 inch from turbo back exhaust
500hp fuel pump
it will be getting a clutch soon enough and an lsd.
from there ive always wanted to go bigger turbo and ecu.
However, once you begin modding cars you realise it isnt going to happen as quick as that-
so my question is, what other things can be done to improve performance without having to go ecu turbo. im thinking along the lines of porting manifolds etc, im not looking for massive gains, but anything would be an improvement. Gotta keep up with the jones's you know
as a benchmark , it did a 15.0 @ 98mph , with 2.9 60 foot times, due to me not wanting to destroy the stock 31 clutch in the car, this was before any mods, ie no cooler or zorst, and a misfire under hard load.. which was found to be a coil. goes alot harder now , turning 2nd gear with a slipping clutch on acceleration. and beat a car that had ran 107mph 3 weeks ago.
I look forward to any suggestions that you may have, as im keen to see how far this thing can go before going to bigger and better things.
