@@TurbineResearch those pistons don’t have the dome profile to match the 885 head and thus you’ll run into the common detonation issues associated with big stroke M20s. 885 combustion chamber is a semi hemi design and requires proper quench to run the way it should. Such quench cannot be achieved with a flat top style piston under an 885 head. As far as I know, JE is the only company with that dome profile on hand. Pistons with the correct 885 profile can be ordered from Top End Performance, or straight from JE if you’re used to spec’ing pistons
Killer quality on the video!
Thanks mate ☺️
Was going to do a 2.9 but IE doesnr sell those piatons anymore so ive decided to do the 3.1 as well, already have the 3l crank now just need pistons
You can call CP directly for these or get them from VAC motorsports

Can you bore the cylinders to 87mm with all the s54b32 rotating assembly? Or put the m54b30 crankshaft with s54b32 pistons?
Late reply but no the m20 can be bored to 86mm only, anything further and the walls would be very thin. Hope this helped
is the Bore Liner Piston can be remove?
Not for this engine
Is there any more limitation due the thinner bore lining by going 85 mm
Not with the M20. The cylinder walls are very thick even compared to an m50
U can go as far as 86mm bore
What transmission you plan on running?
Gforce t101
Updates?
None yet
good
Thanks 🙏
600 is easy 👍🏻
