I know from searching. Some people we're sketched out....but no one actually had experience or knew the specs of the turbos. I actually searched hard and found the specs.

my friend has a obx to4r turbo on his fd. he is pushing 340whp on stock ports @16psi but on pump gas (89 octane) i believe that with a more agressive tune advancing spark he could get bigger whp. he has been using it for over a year with no complaints.

from the stuff i have read here i wouldn't recommend it. try the master power turbos. they are cheap as obx but much superior quality.

 

I wouldn't skmip on the turbine. Do some searching on XS Power Turbines and see what you find. All I have seen here is someone have problems with the oiling of the unit itself and the turbo just burning oil. Also the power was significantly less than advertised.

 

thats what they used to say about master power turbos?

 

you could get a t04r non bearing turbo garrett for 900 bucks. i have seen the obx t04r go for 600 bucks. for the 300 bucks i would go for the garrett no question.

i think that you can't go cheap on turbos nor wastegate. everthing else like manifold, downpipe etc..... you can go obx or any other chinses knockoff
