Why not send out shell to be dipped / blasted?

Little bit of rust I would not have been aware of if I didn't do this. I couldn't see it on the inside of the floor but it actually went into a hole when I cleaned it up.

Messy job!

Every time I ground some off I would spray that area with etch primer when I'd finished for the day.

Well I decided to leave the engine rebuild for a while, and there are a few things I need to think about for the engine bay, so while I was waiting for some more parts to arrive for suspension and drivetrain, and to save up some more money, I decided to start on the underside of the shell.

I knew this was going to be a huge undertaking and painful, so I determined in my mind to attack it and keep going until it was finished. Just over 40 hours later it was done.

To do this job I decided I needed to put the shell on a rotisserie. I ended up making one out of two $80 engine stands.





Now to start on that body deadener



I found the best way to get this off was with an angle grinder with a big coarse wire wheel on it. It is one messy job and not for the light hearted!

So after the first trial fit of the engine I had to take it out and do some more beating of the firewall and leading edge of the tunnel as my engine sits a bit higher.



I needed to massage the firewall up higher than in this picture to allow for the water pipe outlet that runs across the back of the engine to clear.



My engine sits up a bit higher due to the engine mounts I'm using which are e39 525TDS motor mounts (part number: 22111094248). They are 3cm higher and give the needed clearance for the bigger e36 steering rack I'm putting in. These aren't available here in Australia so had to order them from the UK. Of course you can probably use some from Garagistic that are the same height but I deliberately chose to use rubber mounts here for the engine and gearbox as I didn't want too much drivetrain vibration/harshness. I'm using poly stuff everywhere else though.

And its in.

Not for long though, still have to finish all the engine bay shave, and rebuild the engine, but more on that later.

Thanks man, nice to know all this work is helping others.



If they work on LHD also, I bet you could sell them fairly successfully.

Yeah I reckon they would, but it's hard to set up for a LHD car here. There could be plenty of guys here in Australia that would be keen for a set though.

Thanks mate. I have to say , I had found your build a while back and it along with others has inspired me to do the swap. Looks fantastic.

Thanks for that mate, yes I will have to do the same with mine. Have been checking out your swap too. So much for me still to do. I love the 340i badge on yours.

As far as the exhaust manifolds go, I had purchased the Garagistic ones as they were confident they would still work on a RHD car, but they did not. The passenger side (your drivers side) runs straight in towards the starter motor mounting hole (yes ours is on that side) and the other side fouls up with the steering colum. I have sent these back for a refund and I'm now getting some custom made headers done which will be just like the Ergen headers below but half the price. I'm looking forward to seeing these done.

Cleaned all the front crossmember and Diff carrier up and etch primed them just to stop surface rust forming on them as I still had to weld all the strengthening bits on them which I made myself.



Took a lot of wire wheel work to get the crossmember cleaned up.





I will clean all the welds up and make them look pretty.



In hinesight I could have made this strengthening plate a bit wider but I still think it is plenty strong enough.

Seems like the the 318's and early model e30's had the fuel filter in the engine bay like that. I moved mine in front of the driver side (US) rear wheel just below the fuel pump like the 325i's had. Just a heads up, you'll likely want to do the same (it was really easy to move)

Good luck on the swap!

Just noticed you're a RHD car too. Curious to see what needed for your drivers side exhaust manifold!

Bit of rust in the normal places. The rest of the car is really good though.







Engine brackets and mounts arrived so time to test fit the engine and work out where to beat the firewall in.

Hello fellow M60-r.
My swap is in progress too, looking forward to your thread.

Just had a look at your thread, nice!

You're a lot further ahead than me mate, so I'll be following to see what I can pick up haha.

Looking good. Love the colour of your valve covers, and that light weight flywheel.

I ended up selling the donor M30B35 car and made a bit of money on it which enabled me to get the M60B40 engine.





The M60B40 was very dirty when I got it. Many years of grime built up on it.



I cleaned it up a bit with the jet wash.



More build pics to come.
