I like !

When do you think it will be done ?

Side question: The 540 drive by wire throttle body you have, do you have any idea if it would work from an electrical stand point with a 330Ci, as in plug & play ? I understand some port matching would need to be done to the 330 intake manifold.

thats the plan...

hopefully have the n/a version up and running by next weekend for break in, then turbo after i get a new clutch and injectors, and fab up the exhaust and intercooler piping.

I wish I didn't see this. Now the gears are turning again.

I ran the car last night for the hell of it. Currently it has the stock 328i throttle body, maf and intake w/ old oem filter. Factory exhaust and all the settings on the piggy back are set to zero as far as performance. So basically a completely stock setup minus the 3.2l with zhp cams and m50 manifold. Car weighs 3580 with me in it and ran 15.01 @94. Pretty slow... But based on hp calculators 232 rwhp. I feel it's broken in, and now ready for the e85, 540 throttle and turbo...

Probaly not, but that is very awesome!

I don't know, I have a tendency to agree. 232whp is about what I estimate I made when I was running 100mph trap speeds in my full weight car, or perhaps I made even less power, others have trapped more with similar weight and 230whp. 200whp yields around 94-96 depending on plenty of factors. both stock e46 330ci and e36M dyno similar numbers in the 190-210whp range. some e36s can't trap but 96mph, others trap 99+/stock. There's a significant variance in what people call stock, and dynos- that difference alone provides enough variance in hp that this question is moot. But 15.0@94 is just a very thin hair faster than my completely stock e36 325i nonvanos.

But who cares!? this project is low compression. The entire point of this thing is to have a charger attached and to fulfill the numbers claimed in the thread title. NA numbers are meaningless.

sorry guys its been a while. Ive been slammed with work, working 12-14 hour
days at times and dealing with a custody battle with my kids so haven;t really had much time for toys. The car is still running as a daily driver (on e85) but still naturally aspirated. I plan on getting back into it here as soon as it starts slowing down again.
