I found an M20 stroker on Craigslist that I am interested in picking up. I know a lot of guys build strokers using OEM parts from different engines, but I haven't seen this combo specifically. Does anyone know if this is a good build? Anything I should be concerned about? (Specs below)
I would be putting it in an '86 ETA (manual). I'm guessing I would probably need to upgrade the cooling system and clutch, and would definitely need new engine management, new exhaust and a new gauge cluster. Anything else that I would have to change?
Thanks in advance.
'87 M20 2.5 block
'95 S50 crankshaft and rods
'01 M54 pistons with valve notches "relieved"
CAT performance cam (no specs given)
Head milled .008" with full valve job
Compression appx 10.25:1
Stock valves, springs
Block was honed and checked out okay for flatness
New bearings, rings, head bolts, etc.
Stock thickness gasket
New belt, tensioner roller, water pump, etc.
Crank hub for belt was custom machined for this combo
