Im looking around but I was wondering if anyone had some quick suggestions. Ive been told that a t3/t4 wont support a 3.4L

you can use a t3/t4 if you want. only issue would be turbo manifold setup. might have to go custom. not familiar with 3400 turbo setups. you might try asking raven what he did. he is running a 3.8l turboed
If you are going with a single turbo, then that may be true. I personally don't know what the largest A/R there is for a T3 turbine housing, but a 3.4L will certainly demand a larger one than say a 2.2L or 2.4L typically needs. A divided T4 housing with around a 0.96 A/R would probably suit your 6 cylinder better. If you are going with parallel twin turbos however, then two t3/t4 turbos would work great.
check out v6z24.com for what the second and first gen 3400 turbo guys are doing. Its a great resource
We made a 3400 turbo setup before, shoot us an email, ill send over some pics to show you how we did it
Johnny Turbo( he's on the forums, not sure of his name) has an 01 cavalier with a turbo 3400 in it and he is using a t3/t4 turbo...
