1991 BMW 3-Series 325I

This car was built meticulously and done right! My goal was to build a late model E30 with 400hp that was dependable and could be driven comfortably every day and this is it! It was put on the dyno 3/1/16 and pulled 411 crank hp, 357 WHP & 295 lbs Torque! The car with a full tank of gas weighs in at 2840 lbs so this thing moves! It should be noted that was on the AA tune and it is now on a much better TRM tune and should put down more power than that with the better AFR. Both tunes are included with the sale though. This car will leave e3, e36 and even e46 M3's in the dust all day long and at the low supercharger psi its not harsh on the engine so will last for a very long time.

Since I have owned the car it has been in the shop under a car cover every day. Never outside in the elements. I spent almost 2 years collecting and gathering parts to do the swap and then started the process 01/16 and finished 03/16. I have only put about 1k miles on it since the swap, It's basically a new car at this point and i wouldn't hesitate to drive it across country if needed. I think the pictures and the modifications list will tell most of the story but i highly suggest checking out the build thread to really get a good understanding of the amount of work that went into this car!!

Im extremely honest ( sometimes too honest lol ) and am trying to be as transparent on this sale as possible. I want to make sure the buyer is absolutely satisfied with the car so please read the ad thoroughly, study the pictures and look over the entire build thread so you have a full understanding of exactly whats going on, If at that point you have any questions do not hesitate to ask! i will be glad to help!
