RB20DET TUNING

[mikalkouki]

I'm really looking for some RB20 specialists to give me some opinions on how I should go about handling the project im working on. I have a 70mm trim t3 turbo that im installing. I've got the propper turbo manifold, wastegate, boost controller, and fuel pump, but I keep getting all kinds of different responses as to what size injectors to use (i've been told anywhere from 350cc-600cc), however the one response that seems to be regular is that the cc goes almost hand an hand with how much crank horsepower i want to achieve. Wich brings on the next question... how much horsepower can the rb20 safely produce on stock internals. Once again I have received a variety of numbers from 350hp-500hp. Also what ECU should I go with. How much boost should I push from a 70 trim turbo and at what RPM will max. boost be achieved. Also, what is the true RPM redline on the RB20?

Since you live in FL you have that nice 93 pump gas so you can get away with some GTR injectors (444c), a chiped ecu will work or a PFC would be better. Who knows what the max hp is, the Interent is full of many wonderful tales. Since it's a OEM turbo nissan motor I'd say it's pretty tough and shouldn't let you down as long as everything is tuned right. Whats the hp that your turbo will support? 350ish? The GTR injectors should handle that with no problem.

the turbo supports 650hp.

but how much can your engine support and what are you going for?

like i stated before im not sure what the support of the stock internals is, i've got so many different answers i really don't know who to believe. The car will be tuned for drag/drift.
