Re:88 TBird Turbo on a 4G Hatch??
 

my tbird turbo come from a manual 88 tbird and the number on it is IHI RBH52 do you know the specs?

Re:88 TBird Turbo on a 4G Hatch??
 

The reason I ask is because I have the oil cooled IHI? and a garrett oil/water cooled and I want to use the factory wg but you guys are scaring me with all that 15 psi talk. I'm clear. The wg is tough to pull open though.

How did the button adjust the boost with one springed wg?

Stealthmode,

The button did not change the boost that I noticed. What it actually did was advance your timing some more or retard it. I know that on my 88 auto I would hit almost 10 psi of boost. The manuals ran more... 11 - 15

i pulled the turbo off one the other day, there was no boost solinoid on it. the button has to be for something else...
