b35 engine

[budgerian]

I have an offer for a M30B35 engine out of an e32 complete with gearbox, for an amount that makes it hard to refuse. Since my engine needs a rebuild I am seriously considering a transplant. I know about the motor mount issues, but I have a few other questions:

I know Metric Mechanic sells a nut that goes over the camshaft for use with the L-jetronic distributor.
Does anybody know if it will also accomodate de D-jetronic distributor?
I am looking to transplant the D-jetronic onto this engine.
While I am aware that changing to motronic is perhaps a better bet, the D-jetronic is not only already adapted for running on LPG, I also want to retain the stock appearance of the engine. Is there anybody that can confirm whether this setup (d-jetronic on B35) will work or not, and why, if not?

And third, the gearbox does not have a mech. speedo drive. I have read and searched the issue, but nowhere could I find what needs to be done to install a mechanical speedo, all I found sofar is that it can be done, but not easy. Could somebody tell me whats involved? (Other than buying an earlier gearbox...)

All help as always greatly appreciated.

I do not think the Getrag 260 ever came with a mechanical speedo drive. If the gearbox in question is a Getrag 265, then you can add it by removing the blocker plate and adding the speedo drive gear, not that big a deal. The problem is if you have a G260.

Adding mechanical speedo-drive

If the gearbox in question is a Getrag 265, then you can add it by removing the blocker plate and adding the speedo drive gear, not that big a deal.

Do you know where I could find more info on this or the necessary parts? Turns out my tranny is from an 88 M3, so no mech speedo - really annoying.

You need those 2 parts, you find them in your old 4-speed Getrag :

located here:

and here:

to disassemble such a tool (30mm nut):

and to extract the wormwheel an extractor:

1. To use a distributor with this engine you will need the upper timing cover off an M30 engine that came with a distributor, like the original E9 engine, as well as the little distributor drive shaft (part #6 in the Realoem diagram sfdon posted). With these parts and the "cam nut", you should be able to install either a DJet or an LJet distributor.
2. I don't know much about DJet, but am skeptical about adapting a system for a 3.0 engine to a 3.5 as there seems to be little 'adjustability' in the DJet system.
3. There is no practical way to adapt a mechanical speedometer drive to a Getrag 260 transmission.
The only solution I know of is to replace your E9 speedometer with an electrical speedometer and install the necessary pickup for that, like a "chopper" wheel on the driveshaft. It may be cheaper and easier to sell your 260 and buy a 265.
