'89 318i 6 speed m50b32tu turbo swap build

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.

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

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.

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.

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

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.

Welded a bung in the downpipe for my wideband today. I got my argon/co2 gas mix in finally and some solid core wire for the mig. Wow, this is what I've been missing out on by using shitty Flux core. The welds still very average but SO much better than before!



Other things I've been working on include re-fitting the deka 80lb injectors. Had issues with the Orings leaking and messing with my idle so swapped them from the 19lb and lubed with oil and all good.

Need to find a flange for the downpipe that will fit through the tiny space available between the waste gate and the steering shafts. A normal vband won't fit...

[ba114]

Downpipe done! After thinking this was going to be my most difficult job, I was incredibly lucky with getting the angles perfect first try. Yes the welds are horrible again, however I pressure tested the pipe to 20psi and found no leaks so that all that matters really.

the pilot bearing is part of the flywheel for the 330i/Z4. Make sure you get a flywheel that matches your gearbox and you're good to go.

Nice project you have going here! Much inspiration in reading this :D I am about to install a simular gearbox, the Gs6-37bz, this is same as yours, but m50 angle. But what did you do with the input shaft? its too short to reach in to the bearing like the other boxes :)

Fitted up the FMIC yesterday. Got it pretty much perfect fitment wise.

It's a 450x300x76mm core with 2.5" inlet/outlet.

Only hiccup is I need a longer 3" to 2.5" 90 degree reducer to connect to my maf tube.

Those with a keen eye will spot that I have retained a new parallel core a/c condenser and the stock hose routing made to work. No fan unfortunately but we'll see how good a job the diesel clutch fan does at drawing through air at idle.

Also safety wired the radiator into the bottom of the core support and gained about 5mm more clearance from the a/c compressor pulley.

Nice! congrats on getting it moving! It's all downhill from here.

The new cam angle sensor arrived so i fitted that asap and it fixed the CEL.

So i filled the diff with redline 75w90 gear oil, started it up and started filling the power steering.
After bringing it up to temp, i popped it into 1st and rolled out of the garage! First time moving under its own power....however it was short lived. I couldn't engage reverse. Seems the shifter needed some adjusting so using the 3 socket and vice Method i bent the shift lever backwards and towards the right (its a RHD car), then popped it back in and finally had reverse working!

Took it for a couple of laps around the block and all seems well. Need to adjust the steering wheel as it's off centre slightly but otherwise thing are looking positive.

The clutch needs a good bleeding, as do the brakes and I'm yet to start fitting the FMIC but my goal of having it move under its own power over my Xmas Break has been achieved :)

[ba114]

That's quite normal :D Check the cranck sensor too. It might look the same.

Bought and fitted a new crank sensor already. Should have done them both at the same time but you know what they say about hindsight....

Anyway this should clear the code and hopefully address my idle issue
