A now defunct shop did the swap and the car has never ran right.The owner has taken it to Xat and they were able to get it running better and even tune the car to 240whp with a dyno sheet included.Car still has a horrible idle and runs extremely rich.I have no experience with these swaps and need help.Please post if you have anybody in mind.To clarify the swap its a fwd sr20det in a mid to late 90's Sentra Se-R.
