5" exhaust? will it be a stack going out the hood or you going to put a lift kit on it to fit under the car? thats huge we put a 5" on my buddy's Cummins last week its crazy.

How much did you take off the diff end plate to fit 4 clutches?

It was just about 4mm, I don't have the number written down anywhere sorry.

That L33 probably took 100lbs.+ of the front of your car too. Looks sick man, keep it up!

[Dirk HX35]

Made some progress on the car...
Finished up the diff rebuild and flange adapter plate.


I will clearance the subframe some and weld another plate across the bottom.

Here's the 5" exhaust vs my old 3" hahaha


Worked some on my crossover setup too



Front brakes showed up today, still need rotors.


I saw this picture online comparing gen 4 bottom end to gen 3 and I quickly decided to swap in the aluminum 5.3 I have.



Here's how it looks so far with the catch can in the corner too.


Next up I'm building the trans and setting up a trans pump to keep the gears cool. Still need to order a driveshaft, front hubs/rotors, and small things.

Yeah, but it's for a girly size 1310 u-joint...

My thoughts exactly. I actually bought a jaguars that run adapter before realizing that, I'm going to keep it and use it on my e28.

not sure if you knew this, but jagsthatrun.com sells a flange that bolts right up to the e30/36 6cyl diff for $100

I read the whole deal, this is one sick machine man!

Thanks!

Where did you get those valve covers? I looked for something like that for mine and couldn't find anything like that.

They're ebay specials, I'll find the link to them.

Any updates? This is killer

Thanks, here's some updates.

Rear end is all sorted now.
E36 diff with a 4 clutch rebuild and 3.46 gears, CAtuned chromoly axles, z3 hubs, e46 brakes, camber/toe adjustment tabs welded in, raised subframe 12mm, cut and boxed/reinforced subframe to clear 1350 u joint.


Had to mill part of my diff to accept the 2 extra clutches.


New bolts, bearings, and clutches


It's going to be a tight fit, I still plan on reinforcing the subframe a little bit more just for peace of mind.


Next step is to machine an adapter to bolt the 1350 u joint flange to my diff input flange.


There's not much left to do for the car overall.
-Decide on front brake setup
-Wheels and tires
-Measure for driveshaft
-Make crossover and exhaust
-Buy radiator
-Finish intercooler piping
-Buy seat covers and harnesses

Bought some more parts. Wilwood manual pedal setup because the booster doesn't clear, shaved valve covers (don't worry I'm going to powdercoat them), AN fittings for breather setup and oil feed/drain, and coil relocator brackets.

[ThatOneEuroE30]

Ah that makes more sense.

[Dirk HX35]

Sorry if it's a dumb question, but why weld the trunk shut?

So people cant get out, duh :D

This. What happens when you need to replace shock mounts.

maybe I missed it, but where did he mention welding the trunk shut?

I think he meant to say "trunk shit"

The floor of the trunk was cut out and welded shut for the fuel cell and pumps.

cool build, I wonder whats the difference in the output shaft splines on the 210mm differential? My bud's boosted e21 just shredded the splines on his output shaft splines on his 168mm diff. And I'm pretty sure that small case and medium case axle output stub splines are interchangeable between the diffs, I'm curious if the large case has beefier splines?

Thanks, I can try and measure them when I get a chance, but I believe they are beefier and interchange between all 210mm diffs.
