TU cranks don't fit.
yes you can clearance the crankcase but the counterweights will still hit the piston skirts.
Custom slipper style pistons required, as per OEM.
Dont use the M52B28 slugs though, absolute shite in an M20

how much bigger are the tu webbs?

im going to give the tu crank a shot, iv got slipper pistons to play with as well, all things that we will find out soon.
have you tried the m52b28 slugs? with 130 rods or 135s and re profiled?

i can safely say if you have a TU crank, then one webb will be bigger than the other and there is no hope in hell of getting a m20b25 piston to clear with a 130mm rod,
with a 135 its possible but il checking it out.
