I'm not familiar with an M3 turbine, but 1.06 a/r seems pretty high. Exactly how big is an M3? The compressor side a/r seems fine, but 1.06 turbine a/r will take days to spool, unless the M3 is a very small turbine. If it's comparable to a T3 turbine, I don't even think you'll be able to spool it. Do you have any pics or a rough estimate of its size? I'm really curious to see what it looks like. You can find log style manifolds for relatively cheap if you're on a budget. They can be had for around $200 with whatever turbine and w/g flanges you want. They don't exactly flow that great, but they get the job done without draining your wallet. Or, you can try to find an OEM VX or STD manifold and machine an adapter plate to bolt a turbo to it, but it'd probably cost almost as much as a log manifold would in the end. Post a pic of that M3 if you can, I'd like to see what it looks like.
