This car is now for sale, see here: http://www.r3vlimited.com/board/showthread.php?t=209778

I get alot of requests for info on this car. I've been collecting parts and chipping away at this thing for close to ten years now, my goal has always been to acheive race car performance in a naturally aspirated daily driver capable vehicle. Last time I had it on a dyno it put down about 220bhp but I have made quite a few improvements since then. I will update this thread as the project evolves or until a serious BMW or driving enthusiast buys it from me and I move on to another project.

my god. This is built for business. Good show man, come to the e30 picnic with this!


The only thing I would change is adding some sort of rear apron. Without a bigger one it really makes the car look higher and more naked than it is.

[lbreevesii]

Very nice setup. What kind of power do you expect?

I assume you're using light shockproof gear oil? The heavy stuff is like a liquid red crayola crayon. I've used it in well worn diffs before.

[LJ851]

220 at the wheels or crank? What brand dyno? Nice work!

[bimmerteck]

Well Played! It looks like a lot of fun.

[Erick]
