    .84 A/R too big for the m20 motor? Thanks in advance!

    I would not say it is too big... depending on the wheel trim/stage.. that housing will make a lot of power. A housing that large is best matched with a large compressor wheel that gets into efficiency at a lower shaft RPM.

    I'd love to have a housing that size, but I run a decent amount of boost. If you are running less than 15psi, get a .63 or something for faster spool.
