Just Installed A Rb25det Turbo On A Rb20det Engine, Having Problems! Help!

[Green_s13]

as the others have said re-gp your plugs to .8, and while your at it just make sure they are not sutffed, if that doesn't work then look at coil packs as these things fail all the time on RB's (personally i would just grab some splitfire coil packs) do the simple things first and also make sure all your cooler piping is tight

hey dudes

thanks for all your help

ive been suggested to buy an afc or afc2, would this help too?

im guessing this is what i need to

1. change spark plugs

2. check coil packs

3. install gtr injectors + fuel regulator (do i need a new fuel regulator if ive already got a gtr fuel pump installed and about to install these injectors)

4. dyno and ecu retune

ive been told to back off the throttle and stay below 0.5 bar until my boost problem has been fixed from a retune

gtr injectors and fuel regulator = big no, I dunno who said you need those for just an rb25 turbo!
