Woo! thanks ppl for the info! I'm all over the shop
R33 IMPUL, that combo sounds like the way, but I'm thinking of trying to get round the 300HP mark, bit more. I think cause of that, running the SAFCII etc might not work too well because of the auto factor.
Thanks again guys, you've all been alot of help!
I'll talk a bit more with some tuners and take it from there I think.
