m30 firewall modification

[Doughnut]

I thought that was the brake porportioning valve, I just drilled a hole through it to get more fluid to the rear brakes.

Looking at realoem, BMW call it a "BRAKE PRESSURE REGULATOR" So you are right.

I was mixed up. Sorry about the miss information.

They are actually kinda fun to repair, just pull it apart get the 'o' rings out and head down to your local auto shop for new ones.

Thats a check valve, if it's leaking just pull it apart and replace the 'o' rings within' that's what I did.

Everywhere, just go to town on it.






j/k :)

You should position the engine in and mark on the firewall were it needs some modification.

Have you tried fitting it in there yet? I ended up cutting some of the sound insulation on the firewall, and had about a couple cm of clearance.

^ So, did u get your B35 installed on Position 3 ?

[flawdaboi407]

I mean pos 3 mybad.

I have a m30b35 with e30.de mounts in position 2 and didn't have to bang the firewall, it was close and with no insulation. But if I wanted to get into position 3 then I would have had to beat it a good amount.

So, you can switch to position 3 ?
(using your existing " position 2 " e30.de mounts ) ?
Do they have 2 different mounting holes ?

The b34 heads have a fitting on the back of the head that the b35 does not. This is why some people massage the firewall for clearance.
Here's a picture from realoem:


#11 is what hits the firewall. An m30b35 cylinder head does not have this.

You should not have to touch the firewall with a b35

[flawdaboi407]

I thought I read somewhere you have to bang the firewall to scoot it all the way back for the furthest position.... to clear the head....?

[yert315]

you shouldn't have to bang on the firewall with a b35. especially in pos 2.

I am using Funkmasta's mounts and the b35 fits in there snugly with the insulation still in.
