Thank you very much mate!!!

I will stay tuned to be watching the progress, it would be fantastic have around 10hp exta

My Ride: e30
Meanwhile, still working on my M50 manifold conversion.

I have the cylinder head re-worked and installed. Schrick 264 intake cam and a Shrek exhaust cam. Oil pan and subframe are modified to fit the rear sump on an e30. Oil pump shaft replaced.

I have a set of Raceland headers out being worked to fit the chassis.

To do is little things like fuel injector rail, dipstick mounting and megasquirt loom.

That's a thing of beauty right there.

Will the stock clutch hold up to an M54b30 with the M50 manifold swap, exhaust, and a tune? I ask because its time to replace my clutch and Id like to go down this route in the near future. Im hoping the stock clutch can handle the increase but I am open to input from members. Thanks!

What makes you so sure? Is this how people are normally doing the manifold?

Do you think it would be worth converting to a single mass flywheel or get a new DM version?

Because those modifications still don't make enough torque to overpower the stock clutch. I'd upgrade the clutch only once you get into a nice engine build or forced induction.

You should convert to a single mass flywheel, no doubt.

Since it seems you are doing the whole clutch setup anyway, what about the e34 M5 flywheel/clutch assembly? Very common swap if memory serves me right.

At this point Im probably going with this SM one, its described as being close to stock: https://www.ecstuning.com/BMW-E46-33...eel/ES2702807/

I know the e34 m5 clutch will work on an e36, Im planning on doing that with my e36 next for an FI build. Thats why Im wanting to retain stock drivability in my e46.

Okay. Well the whole reason I would go SM conversion is for weight reduction. So I'd find the lightest on possible in my budget. But that kit seems perfect for what you want. Nice find. Wasn't aware of this SM conversion weighing the same as the DM.
