It’s taken me that long to save up for this. Todays parts total, $2200. Going to talk to the engine builder on friday, the plan is a stroked 2.5l, head work, lighter forged internals, and alpha N with big honkin air box. Trans is a close ratio dog leg, and the rear is a limited slip 3.73, or 3.46, it’s been so damn long i forget.

I assume you mean alpha-N in reference to tuning... Is that because you’re running the individual speed stacks without going to a common plenum? If so, what are you using for all of that? All of the stuff I’ve messed with recently has been phasing out alpha-N stuff it seems.

Right now, we’re in parts accumulating mode. After this, we go to check cutting mode.

Yes for tuning, but it’s mainly because you can’t get a good seal on the front of the big air box, so running that with a mass air is a bad idea because you’d have air after the meter, also don’t want to run a stand alone engine management .. there’s a good little read here..

I don’t have extra, only enough! Look up bmw s14 rebuild costs...it’ll make you faint

That’s an interesting setup, I’ve been looking into running a similar setup on one of the rotaries that is planned to go together sometime this year, doing some big ports and a slide throttle setup where pulling manifold pressure won’t be an option. It just seems like most of the computers that do alpha-N are falling by the wayside without going to the top end of the standalone spectrum. Try finding something that can handle alpha-N but yet advanced enough to handle dual spark per cycle with a dynamic split(all programmed in degrees not time preferably), it’s proving quite difficult.

It sounds like you have it all lined up. Do you have a blog or website with more details and photos? If you don’t please consider starting one, I love following builds.

at that point stand alone seems to be the only way to go for you... a-n only knows throttle position and rpm, the only tune it knows is what you told it, theres no learning.

Yeah... It's no fun. Does the stock computer on those handle that? I figured that era would have some sort of mechanical MAF from the factory.

yes, it had an air flow meter (barn door) type set up, but you can map a chip to handle the alpha n, its a bosch 071 ecu.
