I the 265 that much longer than a 260? That's disappointing.

Have you looked at e30 auto driveshafts? You may be able to mix and match fronts and backs until something works.


As it is, I'm still not sure if I have a 265 or a 260/6.

Yeah it's not a lot longer but it's a couple of inches. Just enough that it won't work. The easiest way I have found to tell them apart is the angle on the mounting forks. Picture the transmission bolted in place under the car. If the mounting points point straight down then it's a g265 if they are angled in towards the transmission it's a g260.

Picture of 260/6 for your reference kronus.

I would at least replace the easy to reach gaskets, and check the back of the head as well. This one tends to leak...

Jean, your engine is incredibly clean.

Hooray! I appear to have a 260/6 and not a 265!

in that case, use the front half of the e28 shaft and rear half of the e30 drive shaft. It will mate up perfectly.

and regarding the headers/down pipe issue. The e30 down pipe flanges are 3 bolt and the e32 ones are 2 bolt. You may be able to get away with using the e28 headers to e30 down pipes. I don't know if they will mate up, but they are both a 3 bolt flat surface flange.

Good to know. What about E34 headers?

You can use your stock driveshaft if it has
the large flange. Use the b35 manifolds. They flow more. :)

e32/e34 headers are the same. Basically the b35 headers have the two bolt and b34 has 3. Look at the picture lowr3vin' posted, the one on the right is a b34 header.

If it helps, I went with the b34 headers for two reasons. 1.) the e24 635 had a down pipe that reduced into a single 2 1/4 outlet, which was perfect because I was planning on having a single pipe exhaust. 2.) I plan on going turbo later and the flanges for the b34 are ideal for creating a manifold adapter.

I did this. It did not work.

I had to have the e28 front half shortened a bit. There is a driveshaft place near me that did it for $90 and it is perfect.


As for the downpipes- if you use e32/4 manifolds, the 325i downpipes will line up correctly, they just wont bolt together. It is a fairly easy weld job to mate the 2 together, any good exhaust shop should do it for under $200.

Went to the car, got photos

Notes for the photos:

1279: large, empty toolkit
1281: driver's seatback frame is bent... backseat is pristine
1283: ugliest headunit on the planet. It claims to be 52Wx4, though.
1292: more seat carnage
1296: shit's all crunched up into the radiator
1297: HYDROBOOST!
1303: getrag 260/6?

[Jean]

Looks like a b34 with a 260/6 :)

[kronus]

How's this look?

[Jean]

I would also inspect all the hoses and such on the engine as well. ICV to manifold hose, manifold to the fuel evap valve. Also oil filter housing gasket, front/rear timing gaskets, or seals also. Also the other shifter component, the white ring that sits in the shifter carrier, they are usually worn out.
