Nick's Black 90 - 3B Swap: Running!

[my2000apb]

agh
you shoulda just spliced them together!!!
it may be longer and harder but youll breeze through almost all other electrical diagnostic issues in the future with the knowledge gained in combing the harni

fwiw the Bentley wiring diagrams are on s2forum

[nsimps]

Was able to turn the motor over last night and found out a few things:
- fuel pump is being triggered
- oil pump is working
- radiator has a seep somewhere

May have located some oil lines here locally from an AAN which should work out just fine. The radiator issue can be handled after it is running. There are still wires (shown in pics below) in question but seem like they are related to gauges and such.

Pretty exciting to know about the fuel and oil as I was worried about those. Next up... Homework for finals week . Not sure how much progress will happen until next week.


Onto the pics:

Wires in question on T10/T5 black(plug is from the 90, loose wires from S2 3b):



Fuse panel connections:




Wires loose in engine bay. Is one of these the oil temp sender?




Green plug - HVAC?




Fuse panel relay plug. What does that Green/Yellow wire do (this plug is from the 90 and spliced into the S2 3b harness):




Cutout on the headlight frame to fit the diverter valve:

Awesome work Nick! Wish I could answer your wiring questions, but I never messed with stock wires. What intercooler is that again?

[nsimps]

I wish you could too! The intercooler is from an EVO 8. Pretty big for a stock intercooler. Should handle my power goals nicely.

Got it to kick over tonight, the leak on the oil cooler line is pretty bad So I didn't want to run it for too long. Now it's time to finish out the school semester and then next week get back at it.

[nsimps]

Got it running tonight. Still a lot to do with signal wires, but it runs! Video tomorrow, I had to stop due to exhaust fumes in the house

[my2000apb]

wooohoo

[scubadave]

Nice! Its all downhill from here!

Now that is in your sites, eagerly waiting for you to finish up now. I suppose I should get started on mine asap lol.

Congrats man! This is going to be at BBQ right?

[Audilard]

VIDEO!!!!!!!!

[nsimps]

Maybe letter today, after Breaking bad.

Maybe letter today, after Breaking bad.

Breaking Bad is over and it's tomorrow.

[85oceanic]

Now where is that video???

[nsimps]

Sadly I had to take the dp off to get the flex pipe, reducer and short piece welded on(hopefully today). Soon. Soon you will hear the wonderful sounds!

[Audilard]

First it's the wife and now it's the welder.....sounds like a country tune.

[nsimps]

It was Breaking Bad and then the welder. Speaking of welder, the dp is in his hands and hopefully will be welded by 6:00 today. My Dad and Johnnyman are coming over tonight to help so maybe, just maybe, there will be a video of it driving!

[PRY4SNO]

*ahem

[nsimps]

No video, no drive :( downpipe didn't get welded so another day gone! I did get a few other things accomplished including getting the good stuck from a bad alignment. Tomorrow is another day right?

[nsimps]

Dropped it on all fours and drove around the block. Found out a few things:
- N75 may be hooked up backwards, spool comes on way too early
- Lots of electricals to figure out: brake light, reverse light, tach, coolant temp, speedo etc.
- I can't wait to get things sorted out and full boost!

Video of it running:

Nice Nick! I'm very happy for you. Let's get out and drive!

[nsimps]

Next week I should be doing short distance test drives. Although I might end up in Bountiful mid-week to get some odds and ends help.

[nsimps]

If I can't get it sorted out this week I'll get in touch, thanks!

Been driving it since last night. I'm limited to 5psi and even switched the wires on the n75 still no go. Need to make sure I'm getting signal to it and quite possibly try a different one. Another issue I'm having is hot starts are pretty poor. It won't start without some starting fluid if it's warm or I have to wait 20 minutes or so.

Feels so good to actually be driving it again though! I've pulled it pretty good through 3rd and seems to be smooth. Can't wait to get these items all sorted so I can just drive

[nsimps]

Was able to get a few things sorted out tonight. A big thanks to Dave for the help!!!!!

Brake light now working (blown fuse, *Face Palm*)
Tach now working
Cleared out ISV (it was all yummy)
Figured out I have a leak in the brake booster. Only when I depress the pedal though. It makes a vacuumy noise. Probably have to pull it all apart to figure out what's going on there.

Drove it over 100 miles today with little issue. Still only have 5psi but that's still more than I had three days ago

[85oceanic]

Congrats on getting it running man! Just watched the video and it sounds good! SO will you be bringing this to BBQ?

[nsimps]

Thanks! BBQ is my motivation to get the next phase of the project complete I'm for sure planning on attending this year, can't wait!
