Started the rear diff brace build today...here's a pic of the material I'm using.

2x2 1x2 and 1x1 square tubing


After figuring out where diff height was I started cutting...started cutting by 10am and by lunch this was the progress



Original channel that comes from factory



E36 diff cover bolts right up...only is sure is the speedo ring need to be cut because it slightly hits the cover...about an 1/8 on each fine.



Here I just laid out some tubing to see how everything is gonna play out. Still need to trim down the rest of the oem channel left on the frame rails. Need to grind off the boddy sealer that's all over and start welding the angle iron support to the rail and get the main brace tacked in place.

A few more updates...here are all the drawings for the cam sensor plate and ls1 coil bracket that going on top of valve cover.

So randy forbes subframe kit is on it's way.

You should watch for chaffing where those lines are laying against each other. AN lines love to chafe through each other.

You could prevent them from rubbing by bolting them together with adel clamps if you haven't already.

I usually say tune anytime you change fuel because all fuel s different...play it safe no need to blow a motor because of lacking a tune.

In a few months ill be tuning for e85 and regular pump gas...even the fact that I canged my inj to bigger ones I would retune on just pump. My tuner is super picky which I love "same guy who tuned your car when the previous owner had it" he always wants the most perfectand efficant tune and never second guesses anything. He also never pushes it to the limit is he feels its not safe.

Megasquirt you can.

NIce work. Do i have to be tuned for e85 or could i possibly use a safe mix of it say 50/50 ...i use it with my bmw 135i ...was hoping i could do the same with the e30 turbo..?

You'll need to have a tune. Stand alone does not work like the stock ecu where It can compensate itself/learn. You could have a second tune hooked up that you could switch on the fly but that's about it.

So I decided to re plumb my waste gates after noticing the silicone vacuum lines were melting. I thought of using Parker push locks but the plastic tunes only handle 140 degrees of heat so that was no good.

I ended up saying fuck it and went with xrp fittings...also re located the oil cooler again, didn't like were it out it last time...here are the pics

1st step of cam syn is done. Waiting on coil bracket and cam plate to be cut out all designs are done just waiting for a machine to open up.

The closest e85 pump to me is about 5 minutes drive, but I still take a bunch of plastic of 20 liter plastic Jerrycan's to fill up as well.

My M20 is using lots of e85, but then it would be using lots of 98RON anyway because of the almost dead state of the motor. My fuel table has 30% added to the entire map via the global multiplier.

5 min is nice i bought a 5gal race container so i can fill that up when i go to the track. I wont mess with the maps myself just yet i need to learn it a little better dont want to mess anything up. My tuner said it wont cost much for a re tune he's also setting up my EBC so ill have everything done while im there for that session and also have ramp boost working which is what im real excited about.

Can only have so much control with a MBC and im kinda tired at being a full boost when not needed. I do enjoy cruising around with my car and full boost isnt needed all the time.
