E30 M52

Who needs some rear cupholders?!?

Headers sandblasted

I am trying out the Eastwood Internal exhaust coating because the ceramic coating I used to use is priced like liquid gold I no longer have any spray guns or a compressor, and I like to experiment.

A new E30 gauge temp sensor arrived. The E30 sensor is M14x1.5 and the 24V head is M12x1.5

So I chucked it up in my cordless lathe and turned it down, then rethreaded it. Works like a charm!

An aluminum water pump pulley and power steering pulley arrived (replaces the stock plastic garbage) the water pump pulley is a smaller diameter and runs the water pump an extra 8% faster. 8% doesnt sound like much but whatever, I bought the pulley because I needed an aluminum one and I mention the 8% overdrive in case any 24v folks are desperate for every last cooling upgrade they can get.

I wish they sold the Sachs spline lube individual packets that come with OE clutch kits. I could only find a tube of it. That means I can install the trans onto the engine tomorrow! If anyone needs some spline grease I have plenty to spare.

What PN is that sensor?

Since the X52 head has only 1 coolant sensor provision, I removed the throttle body coolant nipple from the head and installed the sensor there. The blue coolant sensor location could very well be an M14 thread like the stock E30 brown sensor, I never checked, but the coolant nipple location is M12x1.5

Trans. mated to engine, harness install in progress. Headers coated+painted.

Tis so close to being placed inside of car.

The sensor port is m14x1.5 on an OBD1 head for anyone wondering.  I am 99% sure that there are two m14 ports and one m12 port on the early heads.

The throttle body coolant connection being the M12x1.5 that I used

There comes a time in every man’s build when he has to break out the zip ties.....

Kaiser and JC have been very helpful in sending pictures and info about wiring harness routing. There is at least one bracket im missing that helps with retaining the clump of wires and I cannot find it on RealOEM. Thats okay. Its not the end of the world. The wiring covers I installed jumbled up the natural lay of the wires so it isnt how it would have come from the factory but I feel I have routed wires as safely as possible to minimize rubbing, pinching, or possible electrical interference on the shielded wires.

Enter: zipties

For comparison purposes I am posting the mess under the manifold before and after. Im not really trying to show it off but i cant see both images side by side on my phone so here they are for comparison.

So here it is

OBD2

OBD1

Engine is installed.

I still have a long way to go before it gets fired up or drives but I have freed up the other side of the garage so the family truckster can park inside and avoid the snow.

The feeling of accomplishment from hitting this milestone will give me some fresh motivation to take care of the numerous smaller tasks remaining

Dave, you are the man! Thanks for your help yet again.

[Morzada]

Is it just me, or did your oil filler neck switch ends?

[B C]

Sure did. OBD2->OBD1

The plastic obd2 valve cover has the filler at the front of the engine and the magnesium obd1 valve cover has it in the rear

[m42b32]

Wooo!

[KaiserRolls]

Dang that’s fresh!!!

[B C]

Connected battery, turned key, watched for smoke. Starter works. (Intake and ecu still not connected)

The header rubs on the heat shield on the passenger footwell so I will see if I can do some adjusting with that.

[KaiserRolls]

ICV hum present??

[B C]

no, ecu not connected. I had to verify the powers and grounds before I felt good about potentially frying the ecu [emoji275]

OHHH YEAHHHHH. Leaps and bounds you are making in very little time. Keep cranking away!

I see what you did there.  And I like it!
