Need help with twin turbo set up.
Need help with twin turbo set up. I plan to go with a twin turbo set up on the L33 (5.3L). I just do not know how to read the maps and am not aware of the benefits or disadvantages of the below turbos.
Turbos I am kicking around are sized as follows. (50 mm .63ar) or (70mm .84ar)
What is the max output of these on a 5.3? The engine is currently making 358whp 339wtq on a Dynoject. Set up is going in a 2247lbs Factory Five GTM. Not a drag car, street and occasional autocross only. Which would you go with and what is the capabilities of these two very different turbos.
Any direction would be greatly appreciated.

you have listed A/R sizes not turbo sizes. I would recommend calling Comp Turbo. http://compturbo.com/ Their tech guys are some of the best, they can recommend the correct size and A/R for your setup.
Check out some of the sites sponsors also.
You should be looking for turbos in the 58mm to 62mm.

Before you spend your money go to B-W website and spend several hours with their MatchBott you will then have an idea of what you are dealing with. B-W has a 63 inducer turo that is fairly inexpensive and the hot side seens to work well for engs around 350 cu inches
