I have used this on nissans many times but I'm not sure if it will work on the suby turbo. what we used to do is slightly crush the regulator top increasing the pressure a little. I think it was 10 psi max before rupture. would this benefit the EA82t or am I chasing my tail again.

Just install a rising rate fuel pressure regulator. I wouldn't trust the "smash the regulator" technique farther than I could throw a blown EA82T. Stuff like that might be ok with Nissan engines that are more bullet-proof than the EA82T, but you are dealing with a very picky engine - you need to *know* what's going on - buy an adjustable regulator.

that's why I come to this site. thank you. I'll go with an adjustable then.

:lol:

 

you know they're not really that heavy, it's all in the wrist

Or use a hose clamp on the return line. I ran 12 pounds of boost for 3 years in my turbo wagon and then sold the car. New owner got 2 more years out of it before the grandchildren tore out the front differential.

Did you completely pinch it off, or just somewhat?

How do you fine tune something like that?

Just restrict the flow. Tuned using a fuel pressure gauge. Also used a different FPR that I recall was rated at 55 pounds. Restricted the return flow with the clamp and ended up with 70 lbs under boost. That and a few other mods and the old wagon ran as well if not better than my XT6.

 

Edit: Should mention imo any modification to the EA82T is a waste of time/money unless first the radiator is replaced with a new unit.
