M30 Swap confirmation questions.

[E30Brad]

Getting a lot done on the swap and wanted to ask what you guys did with a couple of things.

I bought the mounts from 'good and tight' and they're fine, except where the driver side one mounts there is the -intake manifold bracket that goes to the block- on the new (3rd) hole being used for the new mount. And because of the new motor bracket being there, it doesn't what to line up an bolt both down to the block. The extra thickness of the new motor mount under the intake bracket is what's causing the problem. It's sorta angled like this > \_

What did you other fellas do in this situation?

Also did you guys just get rid of the E30 oil cooler?

The manifolds / down pipes fit fine - they do on my RHD (which has way less room than your LHD :) ) They basically fit like they were meant to be there.

Just use the b35 manifolds and downpipes. It should slip over, if not get really close, to the factory m20 exhaust just before the cat. That'll be the easiest/cheapest route to go.

That's what I'm going to try to do. I hope the down-pipes fit in the engine bay. (firewall)
Thanks again.

I was thinking of just cutting the E34 M30 manifold flanges and welding the E30 M20 'three holes' on, so I could use my stock exhaust (down-pipe back), but I don't know if they'll still line up individually with everything bolted up.

I'm gonna have to make an M20 down-pipe template and see what it will look like on the M30's bolted to the head.

Welding cast iron is easy. Successfully welding it is not.

As far as I know, any off the shelf m30 headers will require some creativity to fit.

I'm running e34 manifolds and cat. Custom down pipes, y pipe, and cat back tubing ran me $325 at a top notch exhaust shop. Went with 3" single pipe, Vibrant Ultra Quiet resonator and Street Power Turbo muffler.

[E30Brad]

So what have you guys done for the exhaust? The M20 down-pipe flanges down match up with the M30 manifold flanges. (3 mounting holes vs. 2)
Does anyone make headers for this swap?

[E30Brad]

Thanks again for everything. The most help i've ever had on the net.

I've got a few more questions, this should be it until i get started, lol.

1. Do the power steering lines hook up fine to the E30 rack from the M30 p.s. pump?

2. Does the 260 slave cylinder work on 265?

3. Can i use the M20 A/C pump. If not, do the E30 A/C lines work on the M30 pump.

1. yes, don't get a pump from an iL, they have 3 connections and won't bolt up right.

2. yes, all slaves are the same.

3. yes you can and they should fit, if not custom lines aren't that expensive.

1. You have to bend one of the fittings to get it to reach (depending on engine position) but should be fine.

2. Yes.

3. Not sure about the pump but you will have to extend one of the hoses (again depending on engine position)

Get the motor in the bay and running first, then worry about power steering and A/C later ;)

I removed my cruise control so idk about that.

I had to make a new bracket for my throttle cable but the length was fine.

[E30Brad]

One more question, Do the throttle cables and cruise control hook up fine?
