Project 89
Hello forum I am back.
After 3 year hiatus, lets give thanks to my 91 RHD that sacrificed itself to provide the deposit to buy my home.
I have been wanting a silver 87 that has been sitting for more than 16 years. The papers are lost so its a complete parts car. Finally got a car with ownership for $600. Its an 89, black, sports leather seats, mostly complete interior and mostly straight body. However no transmission, torque tube, exhaust and most of the front engine, radiator.
The plans is to strip the 89, rebuild the interior, clean the body up. In July get the 87, refresh the engine and transmission, rebuild the torque tube, put them into the 89.
I wonder if there will be any compatibility issues.
BTW can anyone tell me how to fix the Rennlist App on iPhone? mine does not work.

The PO cut so many wires. he should be shot and or castrated. The seats came up good. I installed the door cards in hopes of straightening them out.

May as well put a manual in it if you are doing all this.

You, my friend, know how to party!

Help! Does anyone know what this harness connected to?
Its from the interior wiring harness not from the engine room.

On the engines.. get a cheap usb endoscope and look at the pistons in each.. 89 has higher compression and IMO are a much sweeter engine, so worth checking the 87 engine to see if its still got the deeper piston dish.

if so, then use bits from that engine to complete the 89 engine instead.. (I've owned a couple of '87's, and an 89).

Finally got around to the 928 after finishing the Vette.
the owner of the 87 pulled a dick move on me and refuses to sell it to me.
Pulled the intake manifold.
I noticed #1 was missing it's injector when I got the car. This is what I saw.

But it cleaned up not so bad.

I'll put some carb cleaner in next.

Anyone know how to bypass the oil cooler?

If you are referring to the two large black connectors in the first picture, one attaches to the EZK controller and the other to the LH controller.

I pulled the plugs and oiled the valves and cylinders, I put on the tbelt.

The motor won't complete a revolution. It stops just before 45 degrees. I put a magnet in but nothing came out. Any hints?

put a bore scope in each plug hole to inspect the cylinders ,
good chance a errant blowfish is swimming inside

With a bit more patience, time and daylight I found a screw in #8. Yeah!!! The engine turns quite smoothly with little resistance. this morning: plugs, wires, intake and injectors got done. Next

This is an interesting project! :)

Pull the plugs, put some oil in the cylinders, make sure the engine has oil too and then crank the engine over with the starter for 15-20 sec.

Did you get the ECUs with the car or are they missing?

rufrob 09-29-2017 11:32 PM

There is nothing behind the flywheel. No covers, not torque tube, no exhaust. I have an alternator, but no Power steering pump, starter, ac compressor, no radiator, ac condenser.
So Im putting out the call for the above mentioned parts. I could buy a parts car here but i dont want to deal with the $100/month parking and $1000 carcass disposal fee. Just a used transmission here cost $2-5000 so thats a no go.I have been searching Ebay, so if anyone is scraping a 928S4 please let me know.

Imo000 09-30-2017 08:56 AM

Financially you are not better off to get a parts car with all the bits you need. Quickly remove what's needed and scrap the rest for a $1000? Shipping all this in and paying for the parts will surpass that $1000 really fast.
In all honesty, this car sounds more like a parts car than one worth saving. Do you have enough Yen to get it on on the road?

rufrob 10-03-2017 06:14 PM

That it’s a parts car is true apart from the fact it has papers. Another parts car will cost me $3000 plus $600-1000 in parking plus another $500-$1000 to get rid of the chassis.
After unless 928 parts suddenly skyrocket my calculations are sound.
