'89 318i 6 speed m50b32tu turbo swap build

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

Found (hopefully) the source or my tuning woes. Seems the cam angle sensor is in need of replacement. I knew of the weaknesses of these once they get old and knew I should have checked before fitting but I just got too excited to get it in and running.



Anyway all the insulation on the wires is destroyed at least 10cm up inside the shielding so a new sensor has been ordered and will be here in about a week.

Slow but steady progress.
Fitting the 6 speed diesel box definitely has its "intricacies" with the tilt of the box meaning the shift carrier sat nowhere near where it needed to.

Eventually after lots of cuts, welds and whatever, the shift carrier and linkage aren't even close to resembling the original items. But finally got the angles and positioning basically spot on.




Waiting on my shifter to arrive from the UK then I can put it in and bolt up the driveshaft and finally see this car move under its own power!

i lack the welding skills

I do too, but it didn't stop me hahaha

[ba114]

I'm pumped. Not jealous of trying to fit a DP past the RHD linkage though haha

Its likely i wont have to. i lack the welding skills to do that properly so may end up taking it to the pros...

She runs!!
So after a year in the making, yesterday was finally the day!

Started first time! More work to be done though. O2 sensors are dead so need to source a replacement. Have heat cycled the engine a few times to check for leaks and all seems well.

Now on to making the exhaust and fitting the intercooler.

Congrats on getting it running..!!

So engine is wired up, intake manifold etc on. Essentially all ready to go...however now I'm left trying to diagnose a no-start situation.

Engine cranks fine, battery is good. Have to pull the plugs and check for spark next. While I'm at it I'll check the injectors for fuel spray. Failing that....don't know.

So this happened tonight :)









I had to trim about 20mm off the e28 m5 mounts on the engine side stud and continue the threads further down. This made it slightly easier (still difficult though) to position the engine over the mounts. Like the guides say, don't bolt the mounts into the subframe until after the engine is positioned otherwise you'll never get the engine mount arms onto them.

And yours was auto originally?

Nope, manual. I want to say the new bolts were ~1cm longer.

[ba114]

Today's progress:
- New 35mm flywheel bolts to replace the dodgy ones my clutch kit came with that were too short. Bolted up perfectly this time!

- Flywheel, cluch and pressure plate fitted.



- Finished fitting the 6spd to the motor (the diesel box only attaches with the 4 M12 torx bolts) and bolted up the starter motor, ready to drop into car.

[ba114]

Not an exact length, but they were significantly longer than the stock ones I removed.

And yours was auto originally? The bolts i removed from the engine were roughly 28/29mm as it came with an auto box, so i was surprised seeing the 30mm bolts with the flywheel.

Anyway i sourced some 35mm bolts in 10.9 grade, nearly impossible to find 12.9 it would seem unless i went to a socket head bolt. Will give these a go tonight, hopefully its all good....

[Northern]

They didn't have thread sealant on them, but I used red loctite when I installed them... So that flywheel is never coming off I guess.
