M42/44 stroked crank

Thought id share this. There is a strong possibility that the Toyota 5S-FE crankshaft can be moddified to fit the M4 series engines. This crankshaft is forged from the factory, 91mm stroke, I believe the mains are a mm larger than the M4 series, so they could be turned do to fit, snout will need to be modded to fit the m4 series chain drive, but probably not too differently than one of the bmw diesel cranks has to be modded. Its been tough to find out for 100%, but it appears the toyota S series engines have the same 91mm bore spacing as the M4 series (or really close 91.5-92mm)

New 5S-FE cranks can be had on ebay for $250..used, much much cheaper....this might be a cheap alternative to the expensive, euro diesel cranks.

again...im speculating here, but all the numbers look good, unless I got bad info, and well, we know how the internet is sometimes.

I'm not sure it would work, though I could be wrong. If you do this let us know how it goes.

That bore spacing might be OK if offset rods were used .5 MM is pushing it a little but not terrible.

Dave,
Thats what I was thinking...I know the bore spacing is really close, and I figured .5mm could be made up for.

Greg.. unfortunately Ive already sold my M42...while I'm doing and engine swap, I was planning to try it, just to see if it could work, but of coarse no used 5SFE cranks were available at the time, and I had a guy give me a good offer for the motor, so I had to let it go. Of coarse a week or so after I sold the motor, I used crank showed up on craigslist for $40....go figure.

If there is anyone out there with a spare m42/44 block laying around, and you got a little spare cash to buy a cheap, used, 5sfe crank, maybe someone can try it. Ive been sitting on this info for about a year, and since I'm not going to try it in the foreseeable future, figured I should share the info with the community.

Why not just use a M47 crank?


Never mind...I post this to show I'm stupid right now. Good luck with that monster...I'm in if it works

If someone wants 5sfe cranks, I got 2 in excellent shape! Get em before I toss the motors. I had turbocharged one, and blew the pistons, and got another but decided to go V6.
