Thanks guys for your support will work on getting a ecu tune and z32 afm and see if things get going. Cheers

Do u need to change the afm also as i am still using the one my Rb20de used to run with??

Yea i guess a ecu tune would be required to adjust or solve the running rich issue

I definetly go for a tune but in fiji no1 does ecu tunning

Hell no it be a wheel bearing Trex

Rb20det running rich after injector swap Hi guys pretty new to this forum need help with my 1990 HCR32 Skyline. So i bought this car it had RB20DE with auto tranny i swap the gearbox to manual than replaced the motor to RB20DET using the DE harness plus the injectors. It worked fine with stock boost of 5 psi. Than i installed a bigger turbo (to4e) the car car started to ping on boost above 7 psi i changed the ecu from a rb20det very little difference was made so i went on to change the injectors to 550cc (mostplus brand) now the car runs so rich and worse than before where it used to run with rb20de injectors. Can someone guide me on the next steps so that i can get to go up till 10 or 11 psi of boost and dolve the over fueling issue . Also the why is the idle so rough. The spark plugs are so covered with carbon deposits i guess thats due to running rich. Any suggestions??
