Rb20det Power Lost!

[Cefi_A31]

guys....

just wanna collect feedback before sending to a workshop and before get conned....

my situation is if i floor the throttle......the power just wont build up and stuck somewhere and the rev cannot exceed 4k rpm....but boost reading showing steady at 0.8 bar.....

but if i build the rev slowly or press the throttle pedal gently..there is no problem at all and the power comes smoothly.....

possible cause fuel pump??? AFM???? leak???? Wastegate???Coilpacks???

some says that have to add one more fuelpump relay

my spec :

Standard RB20DET internals and turbine

GTR Intercooler

Walbro Fuel Pump

Wastegate

3 inch straight catback

pleaseee help me....

An internet forum is not a substitute for mechanical knowledge or a qualified mechanic. It's also not a good place to learn basic mechanical skills.

Good luck with it.

intercooler leak mate

check all ya joiners ( very fine splits will do it ) undo them all move on again firmly and do them up

tighten all clamps

replace all vacuum hoses or atleast check they all tight as well.
