[Gtrs are the s hit!]

hi does anyone have or know where i can get a wiring digram (ecu) for an RB20DET??as im looking for a boost signal wire? to hook up a Apexi boost kit solenoid..

Cheers

there is no pin on the computer for boost pressure according to my FSM. can you post a link to the product you are trying to hook up, I will see what I can do to help.

im not sure where there would be a link..

but this is what ive got its a AP ENGINEERING Apexi Power FC for my RB20DET... this is sweet

and ive also got a power FC boost kit but its for a GTR..

The boost pressure/map sensor plugs straight into the power fc okbut on the boost solenoid side theres a plug where it should plug straight into the factory boost solenoid plug(on a GTR)so i was wondering where i splice the two wires to.im told ones a earth wire and the other is a signal wire...

oooh, you might have a problem there, the factory boost sensor is on the firewall not down on the computer, can you put up a pic of the plug you mean, I'll whip out the GT-R FSM.

hey heres the pic..i just need to know where to splice the two wires to..

they plug into the power FC itself but I do not see the RB20 listed, you may not be able to use it. I have seen a boost pressure sensor thahat plugs into the solenoid though, that may be for situations like this.http://www.apexi-usa.com/elect...s.asp

I know the CA18 and SR20 have stepping motors to control the boost via the computer stock, the RB20 does not so you may not be able to use it. That stepping motor is the same one used in Apex stand-alone boost controllers so if you do in fact have to get one you will have a backup solenoid at least.
