What size turbo for 408
I've decided to keep my Hurron kit and finish piecing everything together.
Engine is a LQ 408. What size turbo should I run?
Also when I ordered it I want to say I had a 44mm wastegate flange put on. Will that be enough or should I add a second?
Is the 2.5" crossover pipe with t4 flange good enough and 3" downpipe?
And last, will stock truck manifolds be good enough or is there a better upgrade?

Ok I just went through this with my 402. Your gonna have to run a T6 turbo first if its a single. I'm running a S475 T6 1.32 Ar on mine but Im only wanting 750 rwhp since its a street car. If your wanting more power you will need a T6 80mm or bigger. A T4 will create to much back pressure. Let me know if you have anymore questions. Also truck manifolds will work no problem with 2.5 crossover.
