engine and drivetrain Question for anybody who’s done stroker M10 research……

[Guest Anonymous]

Other than using an S14 lower end (with its expensive components), are there any OTHER options for building a bulletproof M10 stroker motor?

I’m looking down the road at options for a fresh engine for the car that’s going to get a/c, and would like to get as much torque as practical to counteract the power drain of the a/c compressor. My other (non-a/c) car currently runs a first oversize (.5 mm) bore / stock stroke / Schrick 284 cam / Weber 38 / tii distributor & exhaust / OD 5 speed combination that works very well - excellent power, good drivability, decent mileage and low maintenance.

The ideal would be keep that basic set up and gain some torque for a full time daily driver / cross country touring car that will not see autocross / track time.

Are you speaking of the crank? when you refer to 'lower end'. You have to use the 83mm m3 crank but have many options in terms of pistons, rods etc.

you can have a stock crank modified by someplace like:

www.paeco.com

but I'd guess $ wise you'd more than likely be better off in the long run going with the m3 stuff

I have an M3 Evo2 crank in my M10 block with 92mm forged pistons. That gives just about 2.4 liters.

A lot of torque, but does not rev as freely as a 2 liter, even with a lightened flywheel.

out as the poster was looking for other ptions to the expensive m3 bottom end. I think that for $400 for a crank you are better off stick with the 84mm s14 crank.

Pluss there is the benifit of it being an actual M3 crank. I mean,

have you ever seen one? It is definetly a nice piece. If you use the

Crower rods for an M3 I can't imagine blowing it up.

the 02 crank is significantly lighter.

crank. Period. He was building stoker 02s as soon as the S14 engine became available. He swears by the bullet-proof S14 crank, crank weight was not considered to be a draw-back( and he builds race engines so he is weight conscious). I almost had him build me a stroker for my Sahara, until a new TEP 9:1 bottom end became available to me for next to nothing.
