Hey guys, I have been turboed some 9k miles with a 90k mile car. It has been maintained as much as possible. I have a Hiboost/MAM hybrid kit. A very nice Hiboost Manifold and the rest is MAM. I am running a Haltech tuned by the same guy that works on Superprotege. The car makes good power and has been fairly reliable and am consideringn uping the boost. I'm at 5.5 PSI and want to to to 8 with a Boost controller or change out my WG Spring. Those of you that have a GT28RS please post because this is the turbo I have and therefore wondering how it's been on your cars.

Thanks in advance!!

I got the first gen MAM SS w/ the gt28rs (mpi) and pushin 8.5 psi and its beautiful and smooth since the power comes on easy. i have a 03 protege dx with a msp ecu swap and before i tuned it i was running 6.5 psi and with the 7psi spring in the wastegate with the greddy pro spec II bc and it ran constant but i haven't put that many miles on it and i'm about 2000ft above sea. the turbo good as far as i can see Garret baby
