WTB: 1987 e30 325i gearbox

[phtbmr 0]

Im after a bit of help

Im looking for a gearbox to suit the 1.1 motronic ignition which has the mounting holes for the speed and tdc sensors, along with the sensors, and a flywheel with the lug in it,

Thanks malcolm

Hi Malcolm -

Motronic gearboxes don't need any sensors in them. Motronic gets RPM (from a HT lead), CAS/TDC is on the front of the motor.

L-Jetronic gearboxes have all those sensors in them.

So in your case (if you have motronic) - then either gearbox will work for you.

Also, you can get the sensors from the stealer. You can also get a tap and dye set from Mitre 10 Mega etc.

The gearboxes should have the blanks for the sensors even if they dont have the actual sensors. You can just tap the sensors into the blanks.

A mate of mine did this with his Dogleg when he did the ignition swap.

I would beg to differ. It took me almost a year to find a gearbox for my '87 2.5 conversion. It is Motronic not L-Jetronic. I went as far as building a jig so I could cut the sensor ports out of an auto bellhousing and weld into my 320 gearbox. '87 325's are the only model that run these gearbox sensors for RPM and TDC. I have done alot of research on this and found that even if you find a gearbox with blanks in the bell housing it is very important that you drill the sensor holes in the exact right place or the car will run like a sack of sh*t. Your best bet is to find late model 325 injection , comp and wiring. That way you can run the crank angle off the front and the RPM how ever it gets it from late model.

Andrew, Motronic 1.1 uses sensors on the bellhousing, l-jetronic uses the distributor so doesn't need sensors. Motronic 1.3 uses the sensor on the crank pulley and one on the ht lead.

Maybe I'm wrong but I didn't think they made 2.5ltr with L-Jet?

cheers matt

thanks for all your feedback guys i have been a way for that last week and had no internet,

if i could not find a gearbox this will be the way i go around it

find late model 325 injection , comp and wiring. That way you can run the crank angle off the front and the RPM how ever it gets it from late model.

To add to this, can an '85 g260 be used on a car currently with a '90 g260?
