Turbo Sizing for Rear Mount
Hey guys
Been doing research and seems like the more reading I do the more confused I get. So im looking for a good place to start.
What would be a good turbo for a rear mount on a 350 LT1? Its an M6, and I would only want to run a small amount of boost 7-8psi and try and keep the stock bottom end alive.

It already has LTs and a Cam, so Im still looking into what I should do. I may wrap the exhaust and just deal with a little big of lost spool time so I dont have to do another Header swap, but If the cam ends up not being a good match then Ill just put manifolds back on when I swap the cam out.

I have an LT1 rearmount and tried different turbo's and I would recommend a Master Power T70 with a .68 Turbine. It is waiting to spool at ~1800 RPM on interstate and develops good power quickly.
Go with 2.5" to the turbo and stock manifolds are fine. I would recommend a T4 flange that way you can change to the .96 shell when you want higher boost and power. The .68 will pull to 6k and probably good for ~500 whp and spool quickly for the M6
Good luck
Call modular Turbo and talk to Rob thats where I got mine

What cam is in the car now? Do you have a turbo now?

Do a search for Zombie chronicles. He's one of the gurus of rear mounts and has a very long thread with different ideas he has tried in the past. He and every other rear mount guy will tell you to ditch the long tubes and put manifolds on. I have read up on just about every thread on this board concerning rear mounts until I decided to go front mount a few weeks back.

I know I had a stock LT1 and 400 RWHP is pushing your luck but mine held until I put together a forged motor. Put 7-8 psi on a cammed LT1 and you are out of the range for any detonation--meaning you will break the ring lans if you have much of a cam.
How much power do you think the stock pistons in an LT1 can take? A friend made ~500 RWHP and it held until he made one mistake tuning and hit detonation...
Boost and stock pistons mix like oil and water
