Well, this project never seems to end.
After driving around with it for a month... I want my 4.10's back. The usability of the gearing is better, and highway pickup is very nice in 3rd with the 3.73's. But damn was the spool time better and the overall "smile" factor was much higher with the 4.10's. I am going to go to the yard soon and see if I can find a 4.10 LSD. If not the 4.10 open diff is going back in.
Also, somewhere along the way the turbo manifold has cracked... so I have a rowdy exhaust leak. I need to pull everything apart again so I can have it all welded up with reinforcements added. This manifold is such a pain in the ass...
Well, just thought I'd keep this thread updated for those that still check it out.Leave a comment:

^I do too... ;)
Got EVERYTHING back together yesterday. It was not fun at all because I decided to put in new manifold nuts/studs and pulling that and the turbo was not fun at all. Reinstalling it was even worse.
I did run into some setbacks thanks to Spec. They sent the wrong pilot bearing for my car which was a HUGE problem that we didn't figure out until we were trying to get the transmission mated back up. Long story short, I ended up cracking one of the mounting ears off the upper oil pan. After much cursing I repaired the broken ear (JB Weld cured for 24 hours) and moved on.
With the correct pilot bearing everything went on smoothly as it should. Below are the pics I took.
Old clutch disc and pressure plate.
Transmission all cleaned up and ready to go back in.
Spec clutch disc and pressure plate going on.
Here is the JB Weld fix. It's holding really well and I was actually able to torque the bolt down that went through that mounting ear.
Sexy time. That was the last of the pics as I didn't feel much like taking anymore after dealing with the car all day. We did test the clutch and everything seems good. I have a rowdy exhaust leak now as one of the gaskets at the turbo disintegrated upon removal. I am getting that fixed today and also having a 3" magnaflow hi flow cat welded in to quiet her down some. Also to get rid of some of that fuel smell from the exhaust.
Now I can up the boost to 11 or 12 psi again and wait for the head gasket to fail :( I need to retune it again and will keep you guys updated on the progress. I guess the new gearing changes the needs of the ve table in megasquirt. Oh well, this is the easy part... I'm just glad I don't have to be under the car for awhile.Leave a comment:

Oomph! Open diff's on a turbo M42 and a new clutch (bad ass clutch)! Wish I had a spare 3.73LSD to donate :(Leave a comment:

You're putting in an open, and taking out the lsd?
You're gonna miss the lsd when you can actually grab with that clutch.Leave a comment:

Moar Work!
Well, not done with this build just yet fellas. Clutch slip got too bad to bear anymore and ordered this:
It came in last week so a couple of days ago I made the e30 fly. Look at that height.
Switching to the 3.73 open diff that came out of my 90 325i project car. I pulled it a couple of days ago. Here it is all cleaned up and waiting to go into the car. Got it installed and refreshed the oil yesterday.
Today work focused on getting the trans out, pulling the clutch/flywheel, and cleaning and painting everything that was going back on the car. Also got the dual mass flywheel to a machine shop for resurfacing. It will be ready tomorrow morning so I can get this thing back together if I hustle. Much more pics to come tomorrow.Leave a comment:

^I hope so Danny... not because I need to, but because it would be cool as hell to have an m42 capable of 13's. Should be fun with a set of 3.73's and the new clutch at an autoX.
Here's a shitty cell phone video of the car at the track. This is a 15.4 pass as I didn't get the 15.1 on video. LOL I should upload one of the videos where the clutch is slipping badly... it was horrible.

Took her to the track yesterday and damn is it official that it needs a new/better clutch. LOL my best time was a 16.9 with a blown charge pipe halfway down the track. You have to feather the throttle so much to keep it from slipping... once it slips, that run is done.
Luckily a buddy went with me and he was much more skillful at driving it with the clutch the way it was. He was consistent 15's the whole night. Best result below.

Previous best time before the turbo was 17.04 so even with the slipping clutch it's not a bad improvement. I think it's got a low 14 or possibly even (GASP) high 13 in her.Leave a comment:

Here's a vid of the car finally. It's a pretty shitty video though. I'll get better ones soon. This is just a 0-80 pull and then I give it gas in 5th gear so you guys can hear the clutch slip. The rest of the video is pretty boring, but it gives you guys something to watch.

Working on getting my new clutch in so I can get a dyno, but I think I am going to the 1/4 mile track tomorrow so I'll take some videos there. I want to see what a difference the new clutch vs the stock slipping clutch will make time wise. I'm hoping I'm in the low 14's but we will see.Leave a comment:

^Correct, on both counts.
Update: Had my turbo eat a piece of silicon because I was an idiot. It bent all the fins on the turbine wheel beyond repair. Took me 3 or 4 days to source a new one. So while the car was down, I disassembled the turbo and painted it with hi-temp paint because it was an eyesore in the engine bay. Now it looks sexy and new. It had a fresh rebuild by Danny, and the bearings and everything still looked new upon disassembly, so I just added the new wheel upon reassembly.
No vids yet, sorry... but here are some new pics to wet your appetite.
I also had my hood latch stop working for some reason, so I fixed that problem as well. Now my hood latch works with ease and probably better than it did new.Leave a comment:
