thinking about upgrading turbos??? what all would i have to upgrade for this? i know the fuel pump, injectors and what else?? also what is the best turbo to upgrade too? i was debating between a TD05 Turbos - MHI 16g EVO III or a TD05 Turbos - MHI 20g i was also wondering what type of injectors (cc) should i up grade too. thanks....

Seriously there are 8,000 different turbo upgrade options out there. Research! Nobody is going to tell you what turbo is best for you, because nobody knows what you want out of the car. Almost every turbo upgrade will require larger injectors, larger fuel pump, and some way to control the air/fuel ratio. The bigger you go, the more you will need to upgrade. TD05 turbos do not bolt directly up to our cars, hence modifications are necessary. TD05 turbos are huge and will put out huge power numbers, but realistically, if you are talking about having a daily driver, most people don't need an 800hp daily driver. I know originally I wanted to go huge, but then I got in some friends cars who have ~500hp and realized that will probably be plenty for me to have fun in. Plus I want to keep some reliability and not be fixing/replacing parts every week. Bottom line, you have to figure out what you want, and then you have do some research and make up your own mind. There are a billion threads on turbo comparisons here and other 3000gt forums, I suggest you do some reading.

Like vert said you need do you some research 3si would be a good place to start looking around. IMO stick to TDO4 based turbos that way you dont have to worry about adapters or new manifolds. 19T swap was really popular for awhile. I know with my 15g i was doing i had 550cc injector and a hot wired walbaro 255 .

16g's would be more than enough to make a street beast. A good friend of mine had a 16G set up with AEM Standalone and made an easy 524 AWHP on 93 pump and was still running pig rich. It was more of a "safe" tune. He could have easily squeeked out to 600 AWHP on 93 and who knows how much more on C16.
