Starting my M54B30 swap...

[VinniE30]

Well guys, logic has set in and I've changed my mind yet again. This thread is now relevant to this forum again I'm putting the M54 into my E30 after all, it will make it so I have no downtime with my DD. I'll still be turboing it down the line. I need to order a new pair of engine mounts(probably urethane, love the ones in my E24) and I need to change the brake booster. Once that is done everything will be in line to drop the motor in.

Make a build thread!:up:

progress?

I've finally got money to buy some stuff towards this... Need to buy new motor mounts, trans mounts and brake booster.

Is this the correct booster? It's for an 89 325ix.

Hm its $192 on Rock Auto...and $126 on PartsGeek.

Just bought a little bit of this:

325iX brake booster is on its way as well. Got it for $130 shipped.

Now my question is, will the brake reservoir/master cylinder from the eta bolt to the 325iX booster or will I need to source that as well? I'm sure I'll find out when it gets here but it's nice to be prepared.

Man that flex disc seems sketchy to me. Imagining that spinning at driveshaft speed is unsettling.

Why? Aluminum flywheels do it all the time...

Granted, sometimes they explode :rofl:

Because its an oval.

:| No it isn't...

well it's not a circle is it?

[Danny]

Besides, its 130 bucks. Finding the right driveshaft and doing it correctly can't be much more expensive.

It's symmetrical around the center, what exactly is the problem here?

[RobertK]

Flex discs on driveshafts flex for a reason. To save your driveshaft. There is a reason even modified vettes still run rubber flex discs.

I'd rather replace a $40 guibo than pay $350+ to have my driveshaft rebuilt because my semi-solid flex disc destroyed the u joints.

How exactly is this "incorrect?" Or do you even know?
