well i now have my xr6 turbo on but now have valave float which i guess was to be expected using the NA rb25de valave springs (upgrade to GTR if using this head before you put the motor in your car!)
But considering i can only rev the car to about 5900rpm i think its still making good power and best of all its making 15psi by 3900RPM which i think is awesome considering the 1.06 exhaust housing! It seems to start boosting as early as 2500RPM!
I've attached some of my dyno sheets and engine bay pics, as you can see by the engine bay its pretty stock looking apart from that blue 90 degree silicone hose which is already starting to frustrate me! hehe!
The injectors are up around the 85% duty cycle, does anyone know how much more i can safely push them maybe with a fuel regulator?
Everything seems to be going pretty well apart from a small oil leak coming from the turbo side which i haven't isolated yet and the torque of the motor has made my short shifter move i think which is making it hard to get into thrid gear so i'm going to have to fix that.
Now i guess its just a waiting game to see how long the RB20 gearbox lasts, its in pretty good nick but the torque is crazy.
The only problem i'm finding is that first and second revs out so quickly its virtually unusable especially with my rev limit set at 5800RPM, I've just purchased myself a Nismo 1.5way LSD so before i put that in i think i'll put some 3:9 diff gears in!
