upgrade
Do you have an upgraded/hotwired fuel pump and adj. fpr? If not, you should get one before the turbo upgrade. If you do have one however, a limit engineering ta-33 is a choice. You can have your stock turbo upgraded by john craig to a ta-33, but it will run about 785 +shipping. What he does is rebuild it and does some milling to the inner part of both housings, and puts a larger exhaust turbine and compressor wheel in. the stock turbo flows about 390 cfm at 15psi, whereas the ta-33 flows 700. They are good for about 35-50 hp over stock and bolt right up because the housings are the same.
