Thanks. Being in school sucks though. I have less free time than people who just work and a lot less money. Can't wait to be done with it.

Thanks! That was no accident, I bought this car with the specific intention of turbocharging it and making it into a fast, fun DD.


Forgot about this before. I upgraded my fuel pump at the beginning of October. It just wouldn't start in my driveway one day (excellent luck) and I wasn't getting any fuel. I pulled the fuel pump assembly out and immediately the problem was clear; the solder joint where the wiring for the pump meets the terminals was broken, the pump was still good. I had already overnighted a Deatschwerks fuel pump though, so I installed it.



As you can see, it's pretty much a drop in replacement for a stock fuel pump. I like these Deatschwerks pumps, they have a much better warranty than Walbro and are reasonably priced. This one is rated at 255lph@40psi, way more fuel than I'll ever need. They are pretty quiet though, so no cool race car noises.



After I did this upgrade, I had a feeling I might need to re-tune a little bit because I figured I was pushing the limits of the stock pump, and I was right. I had to decrease the values in my fuel table by around 8% at max boost, showing that I was definitely encountering a lack of flow which was making longer injector pulsewidths necessary.

I was just looking at that pump, thanks for putting up a couple pictures.

Is the pickup sock connection the same as on the Walbro pump?

[varg]

I'm not sure. Looks to be around the same size to me, but I don't have them side by side and can't measure mine.

Any new updates on this car?

I usually don't care for m42 cars but for some reason I like that you move fast when you do stuff to your car.

[varg]

Why thank you, and as a matter of fact, yes. Quite a bit.


I re-fitted my exhaust and changed the muffler hangers, increasing ground clearance and eliminating an annoying rattle.


Sorry, no "after" just this before pic. The angled, staggered hangers are gone and I cut the big muffler off and re-welded it.






I painted my door trim, making the car the trim surrounds look worse in comparison.






I took some more pictures.









I took my garbage to the drag strip and put some numbers to my work for the first time.



Unfortunately I couldn't get it to hook and my best ET was 13.846. My best trap speed of 103.06mph pretty much confirms my estimate of around 250whp. Next time I'll grab a cheap portable air compressor before I hit the strip so I can air down and get some better traction instead of drag racing with 30psi in my tires like an idiot :fishslap:, oh, and I'm planning on installing launch control in my Megasquirt.

I also did a couple of things I don't have pics of. I installed a subwoofer in the trunk, not for big thump, but because I was sick of having no lows at all, replaced my clutch line with a fancy braided stainless one and did a turbo re-build. And yesterday my sunroof decided being leak free was so 2015 and dumped water on my laptop as I took a turn.

On my list of things to do soon is an E46 steering rack swap to complete the package of handling mods, sanding and painting the rusty sunroof panel, and maybe a bigger turbo.

Welp, I just read the whole thing. Idk how I've missed this for so long. I love it. The car looks like it's hiding things (in a good way). Great car man.

[Good & Tight]

Nice 1/4 mile run, car sounds smooth.

I see your enjoying all the rain also.

[Dj Buttchug]

looks good. The 318is badge you have is for an e36!

[gart]

Wow, just read whole thread. Good work! Glad you're getting to enjoy it finally.

[Razor1981]

Awesome

Great build and information. You do great work. Keep it up. Can't wait to see more, Don't suppose you have gotten anywhere on the MS write up? :popcorn:

What did you use to paint your trim?

Thanks, "nice 1/4mi run" means more coming from someone who has a car that could smoke mine if it coasted from the 1/8th mile mark :D

Yep, and I really like it better than the E30 style badge, it just seems to fit the styling of this late car better.

Nah, lack of interest from others and being busy on my part means it has been collecting electronic dust in my hardrive.

What did you use to paint your trim?

Rustoleum satin black spray paint. I scuffed the trim with a brillo pad, cleaned it with simple green, and painted it. So far it's holding up nicely, no sign of peeling or cracks.

More to come.
