'89 318i 6 speed m50b32tu turbo swap build

[ba114]

Build progress is great. You might want to give yourself a little more room on the DP as the engine rocks that direction under load. I found out the hard way.

Yeh it's close, about 6mm clearance from the shock tower. Hopefully it's Ok...

Solid/poly engine mounts? You'll be fine, I have that much clearance to my steering linkage

e28 m5 engine mounts, e21 transmission mounts with aluminium cups.

in other news, i've finished the first half of the exhaust up to the CSB. On the weekend i hope to get the car up on the ramps to finish the back half.
I also just updated the first post with a list of things done. Sometimes i forget what ive done, i'm sure that doesnt capture everything either.

fitted the muffler yesterday. As this is a 318i shell, it only had the cutout in the rear valance for a single tip. I traced the outline of the curve onto some cardboard and copied it onto to valance before cutting with an angle grinder and tidied up with a grinding bit on the dremel. Turned out pretty close i think! For fitting the muffler, i used the original hanger locations with hacked up stock muffler cages. Also used the rear most headshield stud to keep the tips in position where i wanted it.

Have welded the pipe work from the muffler up until the hanger location under the rear subframe where i have put a vband clamp so that the centre section of the exhaust can be separated from the rear. I would have liked to have finished it this weekend but i need to get a couple more bends before i can mate it up with the rest of the exhaust but i'm glad its getting closer! My flanges for the downpipe should be here on tuesday/wednesday so hopefully that'll be the last of it.

Finished the back third of the exhaust and picked up a
some presents from the airport today :)

Nothing major today. Fitted the tialQ BOV.
Also pulled my shift carrier out and starting another one from scratch as I didn't like the quality of the last one.

Couple of minor updates:
- Finished building my new shift carrier. I'm not setup to weld aluminium unfortunately so a combination of JB weld, then fibreglass will hopefully be sufficient. Had to Bash it pretty hard when trying to get the bushes in and it's holding up easily
- Found a place to mount my catch can. The mishimoto bracket slots into the space on the coolant reservoir with only minor mods
- Welded a new flange to end of my downpipe so i can mate it to the rest of the exhaust
- New tyres arrived for the ESM-002Rs. I went with Nankang NS2R semi-slicks in 205/45/16 for the front and 225/45/16 for the rears. Will get them mounted next week and see how the fitment is.

Didnt spend too much time with the car this weekend so only go minor things done.

I modified the coil wiring harness so that it exits out of the beauty cover instead of next to the downpipe. Was pretty simple, just opened the wiring cover, cut a groove directly opposite where the existing plug exit was and put it back together.
Then just cut the beauty cover where it exits. Not the cleanest example, but should work well.



I also wired up the wideband display i bought from george graves. All went smoothly and easily enough. I used the radio switched 12v, ground and illumination wires and the ground and 5v from the innovate lc-2 controller grounds.

All works well however there is about a 0.1 to 0.2 AFR difference between the innovate gauge and this one; nothing major.

Testing fitment.... guards need rolling and minor pumping.

[ba114]

And now on the ground. Finished the exhaust today. Not doing that job again. It fits, it works, but it hangs too low. Oh well.

Guards being rolled tomorrow

Looking good!

Had to make a minor adjustment to the rear carrier support bushing. The driveshaft bolts were lightly tapping the shifter in 2,4&6 gears.

Fixed that through cutting the locating holes off the carrier support bushing and notching it further down. Then bent it so that the bolt would still line up with the body mount. This raised the carrier by about 4mm which was enough to clear the driveshaft.

Drives perfectly now!
Re-fitted the bonnet and gave it a bit of a clean. Thanks to IG filters for making it look better than it does



Time to tune!

Nice! Still need to fit the valence?
