I have the on3 kit and love it....I was running 7-8psi on the street and wanted to try the other springs it the waste gate...Holy crap my car was nuts at 14psi on the street. I had to back it down to 10-12psi in fear of splitting my stock short block (for now). Mind you im running 275x50x15 mickey drag radials. I love it.. Never had it dyno'd but it's making some steam..Still working on my tune a bit.

im getting the power master 70 trim turbo upgrade. QUOTE]

why the upgrade?
if your running stock block which will only hold 500ish hp and base turbo is good to 600 id save 300$ for supporting mods. ive talked myself out of the upgrade also, maybe someone will convince me otherwise

I had the On3 kit with the base turbo on my 90gt for a year with no problems. I also have the On3 kit with the upgraded Master Power turbo on my 92 and can tell no difference between the base Chinese turbo and the Master Power. Perhaps the Master Power will last longer. Only time will tell.

I ordered my kit with the MP70 and love it. I was told the MP is a better turbo. My car is a beast compared to when it was on spray.. Great kit for the money you can't go wrong

I just ordered a kit last week and they're not offering a 70mm MP turbo at this time.

You can get the 67mm ball bearing turbo upgrade for $350ish if I recall correctly.

I got the standard turbo with the kit....So far it performs great. I think the key to longevity is making sure its getting good oil flow to it (clocked correctly) and your drain is correct. I guess only time will tell. I figured Id save my money and if the bearings go bad I will just buy a Master power outright for about 750.00...Oh I forgot to mention I bumped it up to 14psi and woah!!! On the street it was nuts even with sticky drag radials.

Master Power turbo is now discontinue, you can get any turbo from on3 . Now they carry on3 BB 67mm turbo and 75MM BB turbo as an upgrade.
