'89 318i 6 speed m50b32tu turbo swap build

[ba114]

This is what i am getting:
https://adamat.com.pl/n54-n55-turbo-...2x-kevlar.html

They are making a custom version of this with a starter ring gear position to suit the m50 starter motor. You could use any 8 bolt N54 clutch setup, as long as you use the n54 starter with a 10mm spacer.

Could you post a picture and details on the flywheel, I'd like to use a later 6 speed on my s52 swap and couldn't find a flywheel for my s52 that would work on the later gearbox with internal pilot bearing. Thanks

New Gearbox has arrived. GS6-53BZ from e82 135i.
Custom twin disk clutch from adamat will be mated with this.

325i auto shaft fits fine, no issues with it. 2.93 is far better suited to the diesel box than the 3.15. 3.15 would be best with the petrol 6 speed. Sent from my SM-G973F using Tapatalk

Does the E36 325i drive shaft fit well? Some people say it's short.
Do you prefer the ratios of the 2.93 or 3.15 differentials?
How reliable is the transmission?

And this is why I'm building the new engine. Finally started pulling it apart and decided to comp test it before it comes out. I knew it wouldnt be good, but wow, cylinder 6 (bottom right)... Sent from my SM-G973F using Tapatalk

Cool, I saw your vanos gains on your e46, hopefully you can replicate on this setup.
Any reason not to use a TU or M52 head for the lighter valves? The springs fit, don't they?

And derp I see now where you mentioned MS43 above.

[ba114]

ooh nice update! quite the turbo too. Going to be running MS42 on this for dual vanos? Why did you start with the NV head?

MS43 on this one. Started with NV head for dual valve springs. Sent from my SM-G973F using Tapatalk

New build has got arp head and main studs. B25 used raceware as I already had them from when I was building the b28 bottom end. Manifold and turbo will be for sale very soon Sent from my SM-G973F using Tapatalk

That makes sense, I just couldn't work out given the price difference for the raceware stuff! Send me a PM about the manifold when you know of a price

Looks awesome! I'm a fellow Aussie building an M52B25 Turbo setup so lots of nice ideas. If you decide to sell the manifold you're using let me know!

Interested to know why you didn't go ARP head bolts for your setup?

Pics make this work better. Also designed and printed an adapter to mate the n62 throttle body to the aluminium intake. Sent from my SM-G973F using Tapatalk
