3.4 Swappers! What is the best turbo set-up for the 3.4 to get top performance and no lag? The 3.4 is designed to take the extra stress of a turbo, and that just might be the less expensive way to get that 200+ h.p. without going to all the expense of a 3800 swap. Please let me know what you think is
the best one!

If you have the ability to fab a turbo setup, then you have the ability to do a 3800sc swap and will come out ahead. I love everything about my turbo 2.8, but don't fool yourself into thinking a properly done turbo system is a cheaper/better alternative to a swap.

That said, I'm not one to try to tell someone to abandon their ideas so if you're really wanting to do a turbo 3.4, this thread has a lot of good info...http://www.fiero.nl/forum/Forum2/HTML/129084.html

The "best" turbo is the one that meets your goals. Is your goal 200 hp? That is easily obtainable with a T3. You want more horsepower? Define exactly what you want then find the turbo to get there. I want 340 crank hp from my 3.4 (100 hp/liter) and the GT35 (or similar) will provide the airflow to allow it.

I'd suggest the Garrett app called BoostAdviser. Plug in your numbers and find the required airflow to reach your horsepower goal. Then go find a compressor map that matches. Realize the 3.4 makes peak power at 4500 rpm. It will rev to 6k, but that is past max torque.

Believe it or not, 327 RWHP @397 ft lbs torque has been achieved from a 3.4L P/R engine w cam, intercooling, CO2 cryo cooler, using race gas and a turbo. It may not be the most cost effective/reliable way to horsepower but its works for some.

This is what I am using on my 3.4 push rod turbo setup.

Note that I have now modified my cold air intake to pull in air from my now functional side air scoop.

You can buy that turbo straight from China for less:
