Im am planning on using this on a 2.0 four and wanted to see how it worked out for you!!! Tossing the stock T28 ball bearing for it!!

 

works awesome but doesnt make much more than 300 whp if i remember correctly

 

it will make 350whp....prolly could push it alittle farther...

 

What turbo are you swapping for it? It'd have to be a small T28 for me to even consider the significant increase in price. Esp. if the unit you already have is BB. Here is a link to my old dyno on my B20 w/ a Nissan Pulsar GTi-R T28, pretty much the same specs as the GT28RS for less than half the price, no BB, but who cares. (.60 a/r T3 compressor w/ 60 trim wheel, .86 a/r turbine w/ 69 trim wheel)
