My E30's intro: Say hi to Dexter (no 56k)

[protomor]

Before my hiatus from Neowin oh so many years ago. I got my hands on this E30. I had previously rolled my 85 325e (35mpg :() and my 91 sentra's rods didn't want to stay inside the block. I got into a fun motorsport called drifting. If you havent heard of it, thats ok. I have to explain it to everyone. Anywho, I now run local (legal) drift days in my area and finally took a step down to work on my car and actually drive again myself.

Heres a few action shots of it sorta recently:

Quick mods list leaving many things out from that build:

Saab T3

3" full exhaust with cut out

Walbro 255 pump

42# injectors

MegaSquirt1 V3 running spark

H&R race springs/bilistein sport shocks/H&R sway kit

Autopower bolt in 6 point NASA approved cage

Spec Stage 2 clutch

K-mac Camber/Caster plates

A bunch more crap

Put out 247whp/270wtq at 12psi before the head gasket gave out.

The motor was kinda trashed so I sold it and now I'm doing my M50B25 motor swap out of a 92 525i. No vanos! The plan is to push 15psi on a 0.14" thick MLS head gasket with an HX35 cummins turbo. I'm slowly rebuilding the engine and within a month should have it in. But then I get to wire it in and tune it which should prove... challenging.

I would post the link to the build thread but thats on another forum.. Heres a few build pics tho!

Old motor :(

New motor!

OMFG VANOS JUST KICKED IN!

some of my parts...

nice, what did you regulating fuel in the previous engine?

MegaSquirt. www.megasquirt.info dont go to ".com" lol...

Its a diy EFI controller. This one I mainly built myself but the core was prebuilt. I blew up my last one and didn't want to use up the time to resolder everything. This pic shows the wiring I did for the coil on plug setup as it only does single coil output "out of the box". I use quotes cuz out of the box it comes as a set of transistors and circuit boards lol.

I hand built it, and hand tuned it. Only real diff is that I installed a walbro 255 fuel pump and 42# injectors to deliver enough fuel. I finally got sponsored by a local shop so I let them handle fine tuning. My tune was only off by 15whp. Which I think is pretty good considering ive never tuned before lol.

ah right, i was wondering as you said megasquirt on your ignition... did realise you meant fuel too.

If I wanted to, it could be a boost controller, nos controller, vanos controller, launch control, ASC, blah blah blah. Its really cool because you can wire it to do anything. Its also about 1/4 the price of an AEM unit.

Very nice.

I really miss my old E30 :(
