Need to get something straight here -
you're using a V-belt over a serpentine pulley?

How is this working? wont the serpentine lines cut the V-belt?
im swapping in a 1996 M42 into my car and have an issue with the A/C since its a V-belt compressor and my engine pulley is all serpentine.
is this mix usable?
How does it feel over time?

Ron.

hey. on one of the pictures i saw the intake and the outtake. why you didnt cut the valve guides? i have a similar project here in switzerland.

I have seen this engine run, and from what I can tell, the VW lifters work just fine. Oil pressure is good. No other work needed. Just soak them in oil and try to prime them, then drop them in. Big savings in valve train weight. I don't have a part #, but a search should pull it up. There were a few good discussions about them previously.
As far as the pulley goes, look closer, it is a v-belt pulley. You're right, a v-belt wont work on a serpentine pully.
As for cutting the valve guides, good idea. We didn't think of it. Every little bit helps when you're trying to get this engine to breath better, but as others have mentioned, the weak link in the intake system is the cams. Too much $$ to upgrade the head with new cams. This engine has about $1600 in it, including the M44 crank, rods, and pistons. Cams would have cost another $750-$1000. Didn't make sense.
Eric installed the Mark D 93 chip this past week. And he now has about 1600 miles on the engine. He says it is pretty awsome. He has really been babying it to break it in good. He's about ready to switch over to synthetic oil and let er rip. We'll post some times when we get em.

The engine looks great, I would love to get a closer look at it sometime as I live in chesapeake and work at a shop in va beach. Did the Mark D chip give it a decent boost for power when you put it in?

Someday (probably after a rebuild

) my M42 will be that clean.

Look forward to seeing a dyno sheet for this motor.

The P/N of the lifters I used is 050109309H.

Solid lifters? Got any pic of them?

hydraulic. I have on pictures of the but if you want to see them, look at your BMW lifters, they are identical

strypt · « **Reply #53 on:** January 18, 2008, 07:50:57 AM »

No need to look at them then, thnx anyway

What size samco hoses did you use for the TB hose delete mod?

To do it properly you need a regular elbow and a reducer elbow, because the plastic nipple is larger than the metal nipple on the cylinder head. As far as the sizes, I'm not sure of the sizes as it was a while ago that I purchased them, I used a digital caliper to determine the size of the hoses. I will look and see if I can find the receipts and tell you the size of the hoses.

hello,

well done on a great rebuild an d the best of luck with it....

why did you use the m44 parts instead of the m42.... i tought the m44 parts were cast... and the m42 fordged...?

i just got a second m42 with 110K out and just about to start a rebuild it my first rebuild....

well done again and cheers.

We bought a M44 crank, rods, 2nd oversize pistons,and rings, for $300 on e-bay. All brand new in the boxes. We had been toying with the idea of building up a motor, and this deal came along. Yeah I know about the M42 parts being forged and all. But the M44 crank has a longer stroke, and the pistons had a much larger bore than the M42. It was a no-brainer to go this way. With all the other tips we picked up here and on other web sites, we came up with a game plan that so far has worked out perfect. We are ready to go a bit farther on the next project, a built M42 in a 2002. Looking for the right body to start with.

Regarding the 2 Samco 90 degree Samco hoses used in the throttle body heat bypass setup, did you find that the hoses were in the way of anything? Seems like the temp sender right behind it might be in the way. Anything else in the way?

Thanks...in the process of getting mine back together, too.

Unless you are using a big turbo or homemade blower setup pushing some serious numbers, the m44 crank will more than handle anything you can push. People put too much emphasis on forged parts when in reality, it is actually not needed in most cases.
