First E30, First motor swap. M50NV

You have the wrong radiator in there.

I KNOW! I think a guy here on R3vlimited is going to sell me a late model E30 one with a glove box and a gauge cluster for $115...

Not a bad deal.

So I bought a 325i radiator, expansion tank, gauge cluster and glove box from a fellow R3vlimiter. I am just waiting on the parts to arrive. Once they do I can finish this bastard up, and go get some exhaust fabbed up.

Looking great!

I've never hear anything about this temp sensor in the head! Wut?

Thanks!

I'm using the stock e30 m20 eta driveline that came in the car. I read the driveline is supposed to match the transmission.

Is there any particular reason why the machine shop did not machine the step in the flywheel? The friction area is suppose to be more raised then the pressure plate mounting area as I recall. I only ask because it might cause your clutch to slip or wear prematurely due to inadequate pressure.

goog question. It looks like it was turned on a brake lathe and not a actuall machine that does flywheels.

Makes me miss my NVm50.

Yeah I am pretty sure it was done on a lathe. I took it to a proper automotive machine shop to get it balanced and they said the same thing in regards to it being turned on a lathe. At first he was worried about it, then grabbed some tools to check how flat it was to insure there were no high/low spots. He was really surprised at how flat and straight it was.

Then he proceeded to balance it.

There wont be any high or low spots on it if it was turned on a lathe so you dont have to worry. The outer circumference of the flywheel should be machined lower than the inner contact patch. Im sure itll work if your run it like that, but it might be more predisposed to slipping like a worn clutch later down the line. That and your clutch pedal might sit a bit lower. If it were me, Id take it to a shop and get it properly turned.

Looking fresh.

Keep up that work I want to see vids!

[SkorcherX]

Got the gauge cluster all sorted out.



Also got the covers for the firewall.



And I had a pretty damned good Christmas. Bunch of home use air tools




Waiting on some radiator bracket and mounts, and hoses, and I need to buy a throttle cable.

Can some one please show me a picture (MS Paint would even suffice) of how the wiring is supposed to be done from the green plug on the back of the gauge cluster, to the ECU? More importantly which pin off the green plug is needed, and how did you connect to it?

Thanks!

I agree - I think that flywheel is toast. There's going to be too much gap in the clutch area.

Here's what mine looked like after having it machined at a NAPA shop:
