Engine + Driveline / E36 M42 Tranny question

« on: December 27, 2007, 02:08:11 PM »

Getrag 240 came in several flavors, 1 for the M10 320i and early 318i's.  Later they used a 240 with a different front housing for the E30 318is.  The transmission is an overdrive unit .8:1 in 5th.

The transmission should bolt up to the E36 M42 motor but I think it will slow the car down because IIR the E36 has a 1.1  5th gear.  I would expect the diff ratio in a E36 is ~  low to mid 3.x:1.   I think the E36 used a ZF trans so the length and mounting may be different, you may have drive shaft issues.

Engine + Driveline / diff question

I thought the medium case required a different cross member than the small case 318i units.  This may be totally incorrect but I have seen it several times.

I think any (E30) 325i, M3  and Z3 use a meduim case not sure about the M Coupe.

General Topics / bellhousing for m42

I also think all M5x/S5X bolt patterns are the same as the M42.  I don't know if any transmission has a separate bellhousing.

Engine + Driveline / heater coolant line question...and a pic

Yes the exhaust is probably the hardest followed by mixing and matching parts from a 320i 5 speed trans. in order to get the mechanical speedometer to work.  I've read somewhere that someone converted the 2002 to rack and pinion, then I think you can use the stock E30 exhaust manifold.

If you are talking the heater hoses, the lower hose that hoes to the head is the hot water feed.

The valve back there is a thermostatic safety valve, part of a USA recall.  E30 heater cores have shown a likelihood to fail and dump hot water on the drivers foot.

On the 2002 side I don’t recall which is the hot water feed.  My guess is it doesn’t matter too much.  Maybe the return being on the heater valve side, that way the valve would be a few degrees cooler.  It might last slightly longer.

I like to see your progress as I've thought about doing the same.

I'm not the last word on this but I think 99 cars had EMS, electronic chips in the key for anti theft.  I'm sure there are ways around that.
