ugh, brain hurts.

perhaps i should have gotten an engineering degree before trying to comprehend fuel injection and emissions control systems.

i am such a geek. if only you could see me right now; it's 1am on a tuesday morning and i've got a pad of paper in front of me, a bentley manual the size of a phone book on the left, two more on the right, and google open in a web browser for when i need elaboration the manuals don't provide.

pressing on...

motronic, or something custom?

yup, converting to full Bosch Motronic; and already pondering a similar task on an E30- 325is chassis/cylinder-head/pistons, 325e bottom end, and engine management from an early VR6 (OBDI, uses a distributor, similar displacement, also a 12v).

as for the VW, i really don't see much of a better option for opening up some power on this engine than getting rid of that CIS-E air-metering device; only thing i'm not yet sure about is the throttle body; newer ones have a TP sensor (as opposed to "idle" and "WOT" switches on the 16v), so i'll either need to find some way to rig a TPS onto my existing dual-inlet TB, or get an adapter machined to mount the newer single-butterfly (yuck) TB on my current intake manifold.

if you're willing to say "fuck smog", you could go with a megasquirt or efi332 system - hundred and fifty bucks for your own programmable efi board, built by hobbyists, with source and everything.

then you could go E30 M3 style - single MAP (ick!) meter feeding into a large-volume airbox that an individual throttle body setup pulls from. slight throttle lag, but massive top-end power because your intake runners are motorcycle-short.

ever thought of the 325is head/pistons/transmission, 325e bottom end, 2002 chassis? the e30 motor into 2002 is about as much work as an e30 motor into an e30, plus the 2002 means no smog, and in that case, i'd ditch that evil intake manifold, run the ignition w/ an MSD, and put on a stack of weber DCOE's

that does sound good, but an inline-six in that tiny little body sounds like a recipe for understeer...

maybe into an E21 instead? (the "323i" of that vintage is a six also, right?)

e30 325is m20 SOHC - lighter than the M10 series four cylinders. it's not a fire-breathing 280hp E30 M3 S14B25 like my old car, but nothing will ever take her place in my heart. le sigh.

The secret to engineering. Beer, usually warm. This is because you think you have a quick problem, you grab a beer, set it down and start working. Soon your beer as warm and you are frustrated. You drink the beer, and thing start to become clear, so you think you've got it, and get another beer and set it down. Then you hit another road block, and your beer is warm. You drink it and things become clearer again, and grab another beer. You repeat this until your project meets G.E.F.G.W. (Good Enough For Government Work) standards. Really, it works. This proccess got me through many a mechanical engineering and programming class. What I later learned is this is the same meathod the original engineers used to develop the technology you are currently using, and by drinking the beer, you are able to "achieve" the same mental capacity they were at when devising the equiptment you are using now.
