M62B44,M60B40 heads & cams, Eaton M112 (now with NOS)

You need to pull and flip the S/C pulley for it to line up with BMW pulley.

After my own measuring I've determined that the M62 short block with B40 heads will make 9.94:1 static compression. The folks who assumed 11:1 with B40 heads didn't realize the difference was in the piston height & piston dish volume not in the cyl head chambers....at least not in the engine parts I've found and torn apart to use for my build.

I don’t remember from toolman’s posts, do you have to get the snout of the supercharger shortened to line up with our belts?

Edit: Did you ever finish your research into the supposed m60b44 “high compression” motor everyone claims is created by putting m60 heads on an m62 block?

The intake adapter kit is from a BMW forums member named Toolman. He's put together an extensive kit meant for the '99+ E39 M62's, I'm expecting a bit of modding and shaping to get the adapters to work for this application.

Other goodies have arrived, including the Jaguar Eaton to BMW heads &, idler & blower case mount kit.

Where the F@#$% do you order that shit from?

[flyboyx]

what are the details about that intake adapter? that thing looks interesting. the blower stands up pretty high. I assume you will need to cut a hole in the hood?

The cylinder heads are currently off getting rebuilt. But in the meantime I've started slowly piecing engine bolt on's back together.

It's Alive!

It starts up, idles, runs and drives on the Speeduino EFI. It's obvious the amount of tuning I've got left to do, but it's getting there.

[Mykk540i/6]

Making headway on the standalone ecu.

Installed an OE throttlebody with TPS, wired in the harness. I previously converted TPS to MAP and tune the Bosch Motronic to use MAP signal. The Speeduino is Speed Density and won't allow me to tune accel enrich for MAPdot just TPSdot.



For ease and time I decided to simply just hardwire Speeduino into vehicles original harness. Turning the 80+ some odd wires going to and from the DME down to a basic 20 wires to run the engine.



Haven't fired up yet. Still testing and setting up sensor values. I am already getting Crank sig, Cam sig, TPS sig.





It'll crank and it'll spit and sputter, I'm getting fuel and spark...just not delivered at the correct time to run.

When I get some more time next week I'll keep dialing things in and hopefully running well enough to let the automatic VE tuning do it's thing.

Success, the full MSD ignition works. Feels kind of ridiculous looking out of the windshield to a bunch of ignition coils. But it runs smoother, idles easier and smoother.

Video from the the first fire up. Really thankful the idea worked without a bunch of diagnosis and wire chasing.

With the 4 channel waste spark functional it's now on to the Speeduino EFI install. I'll have some time in a couple of weeks to work on that. Perhaps by then more engine parts will have arrived too.

Just noticed you're in Prescott.

Was this car posted in CL?

Yes, and yes. I've listed the car for sale, I figure I can sell the car. Finish the engine build and get started on the roadster project I have in mind using this SC'd M62.

As long as I've got the car I'm going to keep moving forward on the projects I've already started with it. If I still have the E34 by the time the M62 is ready it'll likely end up in there too for a while.

I know a couple E30's up here, the E36 doesn't sound familiar.

Just noticed you're in Prescott.

Was this car posted in CL? I have a couple of Bimmer friends up in the area, one with an E30 and the other with an Avus Blue E36 M3. Not sure if you know them or not.

[Elysian]

Looks great.

...It's not like putting AFR's or Brodixes (Brodices?) on a Vortec 350... more like putting the M50 manifold on an S52.

This is very true. The valve size and cam durations are slightly larger. Probably not worth the trouble of locating, cleaning, rebuilding and installing the B40 heads.

However I've already got them and I'm gonna run with them.

For now I'm still working on the steps to convert the system to the standalone, so it'll be ready for the boost of the new engine.

Speeduino hooked up the the DME harness for Plug'n'Play



Installing the MSD DIS-4 and waste spark ignition coils:







Kinda goofy looking, but it definitely grabs your attention, make you stop and ask "WTF is going on here"

That cyl #1 ignition lead is a tad long and I'll shorten it up in a bit.
