Just bought some 65mm psd pulleys off matt70 (cheers) and gt inlet manifold plus have a 51mm throttle body coming from z3i.
So firstly what other things do I need to do to ensure safe running of this set up. Current spec of car is r1 ported charger standard pulley and ppp exhaust and that's pretty much it engine wise, standard 1272 bottom end. I was thinking intercooler (i think I'm losing pressure from my stock one anyway. And ppp chip.
Also is there a detailed how to on fitting toothed pulleys
Cheers
