My daily '84 318i m30 swap

[glnr13]

Car's been in paint for the last 3 months. Got it back a few weeks ago.
They didn't paint my rockers in black but I forgot to tell them too. I think i'll just plastidip so i can touch it up easily over time.Swapped the rack for an e46 purple tag.
1) if you have the early steering linkage you don't need to shorten it but you have to position it into the forward subframe mounting holes. Harder to eyeball and measure the tie rod lengths, you'll need to do a string alignment before you can move the car. If you would rather keep it in the original aft mounting position you can disassemble the linkage and remove the giubo. No drilling necessary since it's bolted up with 4 13mm nuts and bolts.
2) I didn't have power steering set up so I needed to reinstall the pump, belts, reservoir, lines.

Had everything except the belt was the wrong length so no driving impressions yet and I need an alignment.


ITBs assembled. Planning on using M20 injector harness but still not sure yet.


Interior cleaned up with a ram ball mount for my phone. Have a tablet mount ready to go down the road when I start fiddling with MS.

Thanks! There's a good amount of clearance at the water pump. My first set of oem rubber mounts allowed the motor to move quite a bit and the distributor left an impression in the find of the radiator. There won't be any progress on the motor, ITB, standalone for a bit though. Need to tend to some rust and get it into the spray booth. Painter is saying not to paint the CF hood, too much flex for paint... Might have to find someone to swap with.Sent from my Pixel 4 XL using Tapatalk

Awesome work. Curious about the clearance of the entire engine and the radiator, not just at the distributor cap, but also at the waterpump. Keep the content coming dude. And here's an awesome video to keep you motivated: https://youtu.be/I2il7mYVi1g

Cant wait to see standalone/ITB progress.

What modifications did you do to get the IE headers to fit?

Also, there is very little info on the wiring required to swap an m30 into an early 318 on the interwebz. Did you use a 320i harness or something?

had to dimple the runner above the motor mount. painful to do that to a brand new set of headers but, it fits and it works + no one can see the dimple from up top.

this is the pinout. I spliced and soldered the harness, cut an end off of the harness from the junks.
Pin 15 has no use on the m30. It's kind of really trippy that the m30 can just run on the 7-8 pins off of the m10 harness.

Are you gonna run a MAP sensor to a vacuum manifold?

That should work fine without a plenum

yeah, it'll be MAP on a manifold for sure. Reading about IAT aiding in tuning but we'll see down the road. doesn't look there's really any room to get a plenum in there anyway due to the brake booster.

isn't the only difference the square vs round c101?

Quick mock up of RHD ITB kit and inventory check. Fuel rail back ordered. Sent from my Pixel 4 XL using Tapatalk

cool build so far! some inspiration to finally jam my M30 in.

[glnr13]

Do you plan on running some type of air filters?

yes, not sure if going to run the ones that clamp over each trumpet or one of those big ITG ones. I'm hoping I can get these to tune without needing a plenum/IAT.

i'm making up for the months/years of not posting any progress pics

This is a dream setup. Always wanted to build a no/low optioned ‘84 with an M30.
