Alpine e30 progress/build thread

super sucky news!
If it were me, I would pull the front cover and and look for tooth damage, then mark the input shaft nut/flange/shaft prior to removal, replace bearing, replace the seal, install the nut and flange to the same position as original, then you should be good to go. I would be very surprised if the flange ears themselves didnt bend but somehow the input shaft did.
nothing should have deformed so the original nut position on the input shaft will be valid for setting it up again.

Can you not file a claim? I received some shit from eBay that showed up damaged because it was packaged poorly. Filed a claim, sent it back, got money back

That sucks=/ It seems the safe way to ship a diff is to make a crate out of 2x4's
Yeah, I think the only way I'd ship one is bolted into a wooden crate from now on. This one wasn't even packaged that badly. Pretty much what I've learned, if you aren't comfortable dropping your box from 5 feet onto concrete, it's not packaged well enough.

It's past the claim period, long story, I'm just going to keep it and rebuild it. I've been wanting to learn to rebuild them anyway, just didn't think I'd be doing it right now lol

That sucks but please be generous on the rebuild details! I have a worn LSD or 2 that need help.
Definitely!

Had a few hours on Sunday afternoon, so I took advantage of the warmer temps and got as much done underneath the car as I could. Laying on the concrete in 35 degree weather is a lot better than when it's 5 outside haha.
The car is officially immobile until it is running on 2 more cylinders, so I took a moment and stored it properly.

This car is very clean underneath! let me know if you need help at any point
Do you know what the main differences between the aluminum M52TU and M54 are besides displacement? From the little info I have they seem to be pretty much the same thing except for the fact that the M52TU appears to be limited in terms of power adders

I'm not super familiar with the M52tu, but as far as I know there is minimal part compatibility between the two even though they are very similar in overall design. The M54 has a lot of small changes that add up to better performance like an improved intake/DISA design, pistons with shorter skirts and low tension rings for less friction (and higher oil consumption lol), slightly bigger cams, and a forged crank in the B30 (same part as S52).

More things done! The m42 is just almost ready to pull, just the cooling system and power steering lines left to deal with.
I also started working on retrofitting the drive-by-wire throttle pedal. I removed everything related to the old cable setup, getting the cable itself disconnected from the firewall was a massive pain... glad that's done. With the pedal mount bracket, I shaved off the lower attachment for the e46 as it doesn't line up, and test fit the bracket in the car. I'll be using epoxy to bond it to the bottom piece of the e30 gas pedal so that I can clip it on without modifying the bracket welded to the floor.
Test fit the pedal to try out the spacing with the brake, it works pretty well
Turned my attention back to the engine. I pulled the intake manifold to clean it and paint all the steel brackets. While the manifold is off I figured I would replace the two plastic coolant pipes that run underneath. Glad I'm going that, this is how they both came out:
They literally fell apart and I had to dig all the pieces out from the block. If the engine weren't on a stand it would've been a nightmare. The plastic is so soft where it meets the block you can crumble it in your hands...
I also got a set of Hella Sharptone horns that I'll be installing behind the grilles. I didn't like the idea of having the yellow covers being visible through the grille so I took them apart and plasti-dipped the covers black. I decided to dip them instead of paint because it seems to hold up better to rock chips.

Got a used OEM DISA valve to replace the busted aftermarket one that came with the motor, and while it was surprisingly still functional, I decided to rip it apart anyway and install the German Auto Solutions rebuild kit. This kit replaces the plastic flapper valve and bell crank with machined aluminum parts held together by a pretty cool titanium screw. The quality and fit of the parts is pretty amazing, highly recommended to anyone needing to repair a failing DISA valve.

E30 PICNIC OR BUST!
I sure hope so! I want to drive it as much as possible this summer

I sure hope so! I want to kick Dan's ass in auto-x this summer
fixed.

More progress.
Getting the block about as clean as it's going to get, maybe 60% done and then I ran out of brake cleaner.
VANOS unit is still grubby but I'll clean it up when it's removed, going to pick up more supplies and I hope to finish it up the cleaning next week. It looks like I'll need to replace the front crank seal, any tips on getting the jesus bolt off on a stand?
I installed the new thermostat, and when I went to install the new water pump I noticed it looked a little different than the one I pulled out...
The impeller was pressed on backwards! Glad I noticed, that would've been a quick overheat. I contacted FCP and they're going to send me a new one thankfully.
Also popped on the SAP delete plate with a new gasket. Its really easy on the M54, just cap a vacuum port and install the single delete plate. I'll be coding out the SAP with the DME (forced readiness) so it shouldn't cause any problems.

Cans of brake clean last two seconds at WOT
Is that a plastic water pump impeller??

Nice catch on the impeller. it would probably run in reverse and make for some screwy stuff. Reminds me of when @Jdesign discovered left hand and right hand water pumps on his 302.
can't trust anybody!
you can also put me on the aluminum block envy list
