Anybody use stock 325 trans mounts with a ZF trans in the swap? I have a set of new ones and don't really want to buy another set of e21 mounts.

I cant seem to find the correct diagram for my 92' 318 convertible... I've looked at this:

but I cant find where it says what wires on the c101 do what...?

[vaughnbannister]

i need some help. my s50 is in my car and all bolted down, but now i just have the wires to do and dont know where they all go, when i search, it just comes up with the harness that you splice in to the e30 body harness. i need something that shows me where all the wires from the engine harness go.

thanks in advanced.

That's still $10 more than the "correct" 24v swap eBay headers, which have been done countless times with little or no fitment issues.

[JdmEuroNorth]

I guess I just don't see the point. Could it be done? Sure it could. But the fabrication would be the same amount. The eBay headers are not really that bad to fit (not saying I recommend them). On my swap the only modifications I had to make were to slightly grind 2 of the holes on the flange. EBay turbo manifolds are going to have the same quality issues. Plus I believe you'd most likely have to run a top mount if you didn't want to hack on the manifold, and if that's the case you'd have to make a down pipe which would be extra work..

The one I found was a rear, bottom exit. $139. I live in Northern Ontario, the cost of shipping a full exhaust is substantial. Emission testing is non-existent. I know it can be done, I want to know if it has been done and the results/sound/ etc.

Thanks guys.

Not causing a problem when you have to make the entire exhaust from manifold back, no cat single pipe.

No. Why create a problem to solve a problem?

Has anyone used a turbo manifold without a turbo to solve their manifold fitment issues?

I cant find the part # for the 2002 brake resevoir. one of the last things I need. I found the blue cloth hose 21521163714 but Im sure I need two fittings in addition to the resevoir itself.

Is this it?

It's pretty easy to find parts when you already have a part number that is used in the same area. Just go to realoem.com and do a PART NR APPLICATION SEARCH with the hose PN and it should get close to where you need to be. Just click around a little.

edit: thanks Jeff!

Here are the part #s to get the 2002 remote resevoir setup
(1)- 21 52 1 163 714 = Blue Cloth Hose
(1)- 34 32 1 112 388 = 2002 Brake Fluid Reservoir
(2)- 34 32 1 102 282 = Angula Pipe
(2)- 34 31 1 121 911 = Rubber grommets for the reservoir

second edit:

you will also need two new grommets for the reservoir also. that werent mentioned anywhere else I looked

Do I have to run an oil cooler for a 24v swap? I know my m42 didn't have one...

No, oil capacity is ~6QT on these engines, you are good without it.
