I have a pair of twin turbos I got from a friend for a good price. I also got a good deal on a 6.2 L92 and started putting together a project. I'm having second thoughts that these turbos are too small for 376ci and just thought I'd post up and get some feedback.

This will be a street/strip car and my goal is to hit low 10's@130-135.

If you decide to sell them I might be interested in them for my 5.3 . I have no idea if they are the right size for your setup though , I am pretty new to this stuff .

twin 56s are not too small for a 6.2

they should still be capable of 900hp, which is far in excess of what you are trying to make

For a 6.2 cu.i., I'd be more concern about that 57mm turbine wheel.

"too small" is an understatement.

beware the people who try to talk you into too big a turbo.

the specs you posted are almost identical to the ebay "t70" turbo, and they are not too small for your 6.2 and your goals.

they will still support far more power than you are trying to make, and you will be rewarded with instant boost and amazing low end pull.

I have a 6.0 with twin 60s (which is not much bigger than the turbos you listed) and im running 6.0s 8th mile using HALF of the power they are capable of providing

They will work ok and with the LS9 cam you're using should make for a decent cruiser.

Of course I'd rather have something bigger like a S366 or the like, but they will work and probably make 15-16psi on high boost before they top out.
