Gcg Turbo Specs

[Bass Junky]

Just made the new Ghetto boost mod by heating and bending the wastegate actuator shaft.

Worked like a charm.

Now the car holds boost nicely, builds boost nicely, not as crazy as before because of the wastegate creeping a little bit as it comes on boost which is normal, but much much better than before I originally modified it..

But I sure as hell now want some anti boost creep stuff on my car!

Maybe look at building a IEBC Bass Junky..

SydneyKid seemed to think it was half decent if I recall..

Let me highlight the issue to people because I am not sure people understand completely what GCG does wrong here ($400 mistake for me!)

I know thats an RB26 turbo, but see how the part of the wastegate that attaches to the actuator has a specific angle to the wastegate cap? Well, when GCG weld it back on, they put the wrong angle on it for the stock actuator. So when you put it back on, the stock actuator arm is too long and keeps the wastegate open on idle...and then also basically until when the turbocharger actually needs the wastegate open.

The way I fixed my issue was like Pete did (as par my suggestion) the first time around, drilled another hole in the actuator. My std nissan actuator now doesnt boost below 12psi.

I therefore suggest for ANYONE putting on a turbo thats had its wastegate modified in any way to check that with the actuator on it is actually shut.

Also, dummy fit the dump to make sure the wastegate doesnt hit anything in the dump pipe (if it has a splitter etc)

Learn from my mistakes

Also, yes, the IEBC is a great boost controller and that is what I use, BUT, big but here, it wont do shit all if the "zero" of the actuator (aka, solenoid fully closed) is already open...
