E30 S52 Build + Turbo Install

[DrLeadFoot]

Making the earth ground for the megasquirt.




Ready for the strut tower!




Getting ready for wiring up the traction control. The brown ABS wire is the ground for the sensor??




Don't mind the bent valance.




Torque Update: There are 4 studs that have a slight creep in them. I'll re-torque tonight. Getting close!

Nice. I'm slowly converting all my vac lines to SS braided as well - just need more fittings and to convert some pieces to accept AN stuff.

Took the spring in the wastegate from 18psi to a 9psi combo.




Old setup.




Turned the attention to the BOV. Pic for reference.




Torque update: Retorqued this morning to 85ft/lbs. Some are good, some have a bit of creep. We'll see what we get tomorrow AM. Once the head bolts are all snug the new OEM timing cover housing bolts will go in with blue loc-tite to 89in/lbs if I remember correctly. Then the cams.

Ordered an EBC and acquired all the hardware to hook her up. Going fuel lines instead of braided this go round for vacuum.

Also rounded up fuel lines and fittings for my billet fuel rail. that has been collecting dust.

No pics from today/tonight but I'll do an update for the r3cord.

- Torque 'd down the head again at 85 ft/lbs. About 6 had some movement until they got to 85ft / lbs. Did this at Noon.

- Addressed the diff speed sensor. She is good to go.

- Cut into the right front ABS signal wire, extended it and pulled it through the firewall for the traction control chip.

- Wired up the sending units for the oil temp and pressure. The gauges are wired up and illuminated. Hopefully...

- Looked at my wiring harness for a bit.


That is all for now.

Nice. I put mine in the same spot.
What oil temps are you seeing with constant aggressive driving? Like, canyon carving, track and whatnot?

Or did you just install the temp gauge?

Highest I've had mine is 240F* in 80F* weather in high altitude. Curious on other oil cooled snail driven motors.

I would give my left nut to be canyon carving right now for two reasons.

1. The cams aren't even in the motor yet.

2. I live in Milwaukee. Our canyons are the Kettle Moraine and they last about as long as I do in the bedroom.

Oil temp setup. Had to drill out the 1/4 to 1/8NPT fitting so the VDO sensor could get all up in. This will be picking up the temp from the cold side of the oil cooler.




I don't think I could have fit a bigger cooler in there. The grinder was used a fair amount and the mounts are temporary...haha

Are you using genuine senders with those gauges, or can you use any type?

I'm using the senders made for the gauges. Not sure if you can use just any type.

You're using MS for TC right? Does it correct for the different signals from diff/ABS sensor?

edit: I see how it works now, this link explains it decently.

What size tires are you running? sidewall and width?

[DrLeadFoot]

Started to wire up my oil temp gauge. Also replaced my oil pressure gauge with a new one.







Used fish tape.




Hardwired my V1 detector.









Rigged up a broken vent.







Retorqued the head studs to 65 this morning. A couple were loose. Retorqued them again around Noon. I'll check tomorrow to see if any move. If they don't I'll go up to 85 ft/lbs.

Cut into the VSS coming out of the speedometer for the rear wheel speed input to the Traction control chip. Still have to cut the front left ABS wires and run them into the cabin.

Pulled the wires through the firewall for the oil pressure and oil temp. Still need to install the sending units.

You're a winner

I'll take it.

New winter car!

2002 325xi automatic. Work and wife friendly. Got a compression test and it is A-OK!!





One out of three working ain't bad.




Head ready to rock and roll!




Done with the block prep. Used a stone, then went to 600 grit sandpaper with WD-40 for the lube. The finish was glass so I called it quits after the 600.




Fresh ARPs




Hondabond on the timing cover.




Cut Rings!






Perfect fit.






New one-way valve.




ARP lube but not too much. Used a rubber mallet to knock in the steel dowels. Also took brake cleaner, Q-tips and pressurized air to clean out the block threads. Used these three steps about three times. Some holes were dirtier than others. :nice:




Initial torque to 35 ft/lbs after triple checking the cut rings were sitting properly.






Tapped the M50 manifold with a 1/8 NPT tap for the multi-port meth install.




The .4mm jets for the intake runners. Also have a single .7mm jet for a pre-throttle body nozzle.




Distribution Block.









Snapped a jet from over tightening...



6 gallon Meth tank.




Wangmanstyle Diff Install!




















Torqued the head to 65 ft/lbs after I re-torqued the bolts to 35 ft/lbs this morning. About 5 "jumped" to an easier spot (about 30 ft/lbs) at this stage then tightened to 65 ft/lbs if that makes any sense.
