    Suggested M20 engine rebuilders / shops

    So, it's 2025 and I'm sure the M20 isn't quite as popular as it used to be, with everyone seemingly using the M50 as a baseline at a minimum. Are there still some reputable m20 engine rebuilders or shops people use? Can anyone point me in the direction of a reputable company?

    Background details: I bought a car in the last few months with a turbo'ed m20 that was fully built and I'd like to make some changes and speak with someone that really knows these motors. Engine is spitting coolant out of the crankcase breather once up to operating temp and I'd like to find out why along with redoing the head and turbo setup once fixed.

    There are plenty of people building and working on m20s. In fact, probably more people building m20s these days than 10 years ago when everyone was swapping in m5x engines.

    We would need to know where you live to suggest a shop.​

      Sorry about that, I really thought I had included where I was! I am in Houston, TX.

          I’m wondering about suggestions in Texas too. I’m thinking about getting a short block rebuilt
