Stock Turbo Upgrade

[Drop Top]

My car has almost 65,000 miles on it. I've noticed a little oil (just a seep) around the intake side of the turbo. Where the air comes into it. Its not really fresh oil just were its seeping and there in dust over the top. Anyway. The car is compleatly stock right down to the origanal hoses and clamps. I'd like to get another turbo before something happens to this one. What my other planes are is to add a 3" down pipe, 3" cat and exhaust system out the back. I don't want to have to go to bigger injectors or modifiy the rest of the car to much more. I don't want to go really big just a size or so up from stock. The car is street driven and if I'm going to spend the money for another one it might as well be a little bigger.

My question is what turbo do you guys sugjest and what fuel pump to change to? Should I get an adjustable fuel regulator? Last qustion. Dose someone make a chip that is streatable for this set up that might help with the ocasinal Mustang? Or should I just leave the stock chip in it. I've located a GNX turbo are they really that differant? Or should I just go with something else.

I guess you can tell I'm new to the turbo game. But I'm no stranger to fast cars. I'm 46 and had many fast and fun cars sence High School. I own some morpars and a few pontiacs right now but this is my first Buick. That ran anyway.

Thanks D/T
P.S. I've already done the spring cleaning.

GNX turbo are very expensive, mainly because of the rariety, not becuase of the difference in performance, they have a ceramic impellar which is lighter which acounts for someof the added horsepower, as far as using one of those turbos it would be a much better idea to go out and get something like a te44, or a ta49, i believe those would work with stock injectors.

DO NOT CHANGE TURBOS IF YOURE NOT GOING TO PUT IN DIFFERENT INJECTORS!!!The stock turbo and injectors are good into the 12's.

Youll need a scantool before you do anything.Do a search,its been covered a million times.
