Did the swap last winter. It was a fairly easy swap the worst part was creating a new wiring harness. My son and I added a fully adjustable Tien suspension, gutted the interior and added a 6 point roll cage. We have done various mods to the engine. Have yet to get the car to the dyno but we are estimating around 230-250 RWHP with the small stuff that has been done. The SR20 is a great engine. Light easily modified and can take up to 500hp on the stock internals. Total investment so far is around $6,800. The car on the track is totally predictable and almost perfectly balanced. The car has no bad habits at all. I prefer running this car over my 90 Z32. It has a much "lighter" and quicker response to any input than the Z. I love my Z but on the track the 240sx really is at home. MaxDoc
