i am trying to get my hands on a dyno tuned eprom for my ecu..

i was wondering wat u guys think is the next best few things to get for it to make it go harder

injectors, and a z maf...as well as a proper tune to control it all.

a z32 maf? i allready run my maf as blow though....so i dont see much point in going to a larger diameter maf as its in my intercooler piping

ive been reading all about ur fullas tuning abilities in america...it seems pretty good...in nz we can do dyno tuned eproms

[20DET]

wat would be the best injectors u fellas reckon...blue top 450cc mitsi VR4 injectors or evo 3 510cc yellow top or mazda rx7 550cc?? or any sujestions?

550s

I'm going with the 550'sMake sure you clean them and flow them before installing. (unless your a beating man)

I've heard that the RB20 MAF max's @ 300, dunno really SEARCH it. I have a pretty similar setup to you. I'm just jumping to the Z32.No sense chipping the ECU twice....

Make sure your motor is running 100% before cranking the boost.

Also do you have cooling mods?

yea alloy triple core burnout competition radiator with twin elecy fans and new genuine thermostat etc etc raised the bonnet to allow hot air to get out..never overheated once not even wen u sit it on the spot in 3rd on da limit!!!!!!!

Doesn't matter if you run blow through. It's all about the resistance of the MAF and the size pipe it's in. BTW, Z32 MAF is the same diameter as the RB20/25 MAF, it just maxes out at a higher hp. 5v on a Z32 = a lot more air than a RB20 MAF.
