M30 swap

[LowR3V'in]

interesting.
My oilpan is about 1/8th of an inch from the steering rack and the e32
downpipes were still way too short.

They would go right into the firewall. :(
Can you take some pictures?

[wildstoats]

I was actually able to use the whole downpipe. So it really does depend on your mounts.

[LowR3V'in]

It's on the collector.

M30 swap exhaust question

Hope this helps.
They actually have to be cut pretty short.
Firewall starts where the left one is welded.

Yeah yeah, "it's not tig welded stainless steal " :P

It helps. Where you put the oxygen sensor?

M30 swap exhaust question

About how long did you leave the downpipes before cutting them? They come with an insulator I'm sure you removed it, right? Any other pointers. I'm using the 325i exhaust.

Nice! I used the front piece of the e32 heater hose with the rear section (including the t) of the late model e30 325i spider hose. The factory bracket that goes on the driver side fender to hold the late model expansion tank is only $5 from a dealer believe it or not, so I picked one up and mounted it to the fender.

Q: are you using coolant hoses for your PS?

I didn't know you could purchase the bracket. Do you have to weld it in?
Yep those are coolant hoses. That is what the local auto part store gave me when I asked for hoses for power steering. Would I run into issues?

Coolant tank question M30 swap

What else you need to get it running?

Next is the exhaust and then the wiring.

Nice work!

Coolant tank done!!

Originally I was going to use the early year tank but the location I found was below the top radiator hose. After a few days of fiddling I finally was able to come up with a way to secure the later years coolant tank but it took a lot of work to get it secured in that location.
I modified the bracket where the air filter was located.


Then had to fabricate some L brackets and a flat one.


After some painting I bolted the tank. I'm not 100% happy how it looks but it will do for now.


Using a 3/4 T fitting I got the heater and overflow hoses ready.


Here is the end product. Only the lower radiator hose needs to be modified.

awesome! i'll take some measurements for you.

[Rob@UUC]

i want to run a uuc dssr badly. but if it wont wok then i'll bend the rod slightly in a vice.

If you can determine exactly what length selector rod would be required, measuring precisely from pin-center to pin-center, we may have an alternate fitting that would work.

Im using a z3 2.8 shift lever... I slightly rub when im in third gear. Very slightly.., you can see a little rub on the guibo but not much. It ended up wearing down to where it doesnt rub anymore. Everything is fine now. I shortened my shiftrod, measured the rod then cut out what I didnt need and mig welded it or wirefeed welded it what ever its called... To make sure it all lined up I drilled two holes in a peice of wood so I can put each side of the rod in the holes and then weld it. Know what i mean lol. Drunkin instructions...pm me tomarrow and get the sober instructions.


I guess you could bend the rod slightly to make it not rub at all...! On my car it only rubs slightly and I figure it will only rub so long till it doesnt have anymore to rub.
