No it won't sorry.the m52 has 4 bolt holes per cylinder outlet on the head.where as the m51 tds manifold has 2 bolt holes each.i test fitted one to my m20 but studs didn't line up
If I cut flanges and weld m52 ones on, would the turbo fit in the gap between body and engine?
Also, would the std m52 lump handle the pressures created?
