E30 S52 Build + Turbo Install

[DrLeadFoot]

Prepared the block with a sharpening stone. I'm glad I pulled the trigger on adding this step.








Need to make that go in there.

Did some Diff stuff and cleaned the garage.

Like a Gilette commercial.




Took the board down the alley then put it to use.

60% lockup? Aren't most diff builds 30-40%?

He added a 4th clutch.

Fuck, nice score!!

I have been running that diff for a while and I've had that cover for 2 years.

Excited for the new Wanganstyle diff he built for me!

I did something. Wrong end of the car but actually turn a bolt.



2.93LSD $150 some bearing noise but it works! I'm keeping the cover :)


I'll hopefully get the 2.93LSD w/60% lock Wangman Diff in there today/this weekend.

I have the traction control under control in my head after a bunch of texts, a phone call and a little research on my end.

Going to make the temp sensor into a vacuum port or find a barb fitting at the hardware store.





Took a straight edge and a feeler gauge to the block at a bunch of different angles. This is the only spot that the .0015" feeler gauge found a gap. It has resistance but it still goes under the straight edge. The area in question is by the coolant port and is a little wider than the gauge. Thoughts?

[DrLeadFoot]

Sorting out a couple more ground wires then I should be all done with the dme side of the wiring harness.

Still need to wire up the new gauges and the GM IAT sensor.

Heat Sink'd the coil drivers.




Where I left it.

New bolts torqued correctly are preferred as well. Anything over torqued and stretched out is trashed. I've also have been torquing everything to spec. No more cutting corners!

Agreed x1000 I've snapped too many "original" bolts while even torquing to the proper values. You never know if some fool had the stuff apart and tightened the crap out of it on reinstall. Even then, I'm sure those bolts get fatigued after 20 years. Good call.

I've also learned my lesson using cheap torque wrenches.

Hmm I replaced an oil filter housing gasket recently that started leaking after ~2k miles. Wonder if the bolts got loose; I'll check. I'm also SCed fwiw. Loc-tite can't hurt!
