Hi, from all the experience here, can someone help please.
Recently imported a GTR promptly blew the ceramic exhaust turbo wheel off the rear turbo (was running about 0.9 when it arrived) so rebuilt both with steel wheels (otherwise stock turbos). Now I know these can run higher boost.
The restrictor in the hose to the controller had already been removed but still only achieved 0.85 - 0.9 max. We bypassed the controller altogether (I know this is normally bad) by running the two hoses together, ran it up carefully and we only get 1.0 - 1.1 bar - goes well but I know there's more.
Isn't this the most we would get ? Surely putting a controller back in the line can only restrict it ? How do we get the extra boost ?
Stock ECU as far as I know, good (big) front pipes, std dumps, 3.5 inch exhaust, pods, the usual stuff.
Any help greatly appreciated.
