DANG!! That's shiny. 

Successful completion burnout video?

Nothing special to report on. I formed up an ECU mounting bracket. The length of wiring harness. Dashboard support brackets, and lack of any decent mounting points on the ECU makes this rather difficult to concoct but I have something that should work.

I finally got around to sawing the header tubes down and installing the y-pipe. This involved lengthening the stock O2 sensor wiring as well as the purchase of some adult diapers for all the brown pants days that lie ahead of me as I scrape the flex pipe all over town [emoji58]

I have about 3” of clearance between the skid plate and mother earth and about 2-1/4” on the flex pipe.

I had a 3” exhaust with the turbo setup too and scraped the flex pipe on some driveway entrances.

I really dont like it but I will run it, hope my exhaust doesn’t get torn off while driving an unfamiliar road, and start working on a new Y-pipe design with two smaller individual flex pipes that are staggered to allow them to fit side by side (doubtful this will fit).

According to something Cassell Performance wrote about S54 swaps and exhaust design you dont want to merge the headers right after the collectors like im doing or else you will lose significant low end power.

So apparently Im doing all sorts of things wrong by having 3” single exhaust with crap ground clearance, and merging it right after the collectors.

This Thursday I am supposed to be dropping the car off with a shop to get the last bits of the system fit and welded, so as long as no problems reveal themselves on the shakedown run, and the weather cooperates, I MAY be able to start driving this thing starting next week

You can have my brackets, I finally got the car home yesterday

let me know if you still want them

I think it would still sit too tall and pinch the harness a bit on the steel brackets under the dashboard so im going to play it safe and avoid that.

Thanks though.

Hmmmmmmmmmm no problemo

The harness ends up like this. jammed up against the sharp edge. This is not good for reliability. Im not trying to overcomplicate things, just trying to make things reliable and the simple fact is, I cant mount it with any of the factory do-dads without it being jammed up on that sharp edge

I always mounted mine with the connector 180° of what the photo shows

Theres not enough length for me to do that either.

Pull harder

!

In all seriousness, that’s odd. Or maybe mine is odd

I did give 'er a tug but everything seemed to be happy with the idea of not budging.

Better to make new brackets than ending up with a fistful of wires not attached to anything anymore lol

Is it an E34 harness or E36? 
E34 harnesses are shorter and usually just barely sneak into the glove box. 
E36 harnesses are longer and have slack to more easily maneuver in the glove box.

Good to know. I am not sure what harness this is. It came from Sir Leadballius IV, which was fitted by the previous owner of his car. Probably an E34 harness though.

Last night I pulled the car out into the street with the open headers disrupting suburbia. There were 2 ~10 year old boys walking down the road and they watched me pull the car out with some sort of curiosity and fear on their face as if my next move was going to be a full throttle charge right at them. Being less of a psychopath than that, I simply turned the car around and pulled it back in the driveway for some coolant bleeding. I didn't scrape my skid plate or exhaust on my driveway entry which is very surprising. The two boys then walked over after i shut the car off and said "HEY, NICE CAR!" .  Lesson of the day:  Loud=Nice. 

 I let the engine idle for 15 minutes or so and it got up to operating temperature for the first time to bleed the cooling system and top off the fluids. Everything is looking good so far and it has a rock solid idle. The lifters were a little noisy compared to the other times I have ran the car so perhaps they will pump up all the way once I start driving and build some more oil pressure and be nice and quiet again, regardless even if they don't, its still less racket than a certain previous engine I owned with solid lifters.

The fuel is very old and unfortunately I have a pretty full tank of it to burn through so once the exhaust is finished I will need to resist the urge to accelerate hard until I can get some fresh fuel in there since im sure the old gas wont jive well with the 93 octane tune.

If you hold 3k idle for 2-3mins the lifters should bleed. If not. Rinse and repeat

If I hold 3k idle for 2-3mins my neighbors ears will bleed.

jk

the exhaust cant go on soon enough though.

Agreed had to do it last year and this year also had some ticking the other day when I started it.

[Daggerty]

For the harness you could take some heater hose, slice it open, and wrap it around the loom and zip tie it closed.

bfh to that 'sharp edge'
