I've got 81k hard hard miles on my 97 200sx se-r, the last 10-15k have been force fed and not a single problem yet. Good daily drivers and get awesome gas mileage and are quite easy to make very quick if you ever got in the mood to do it. The sr20de in the se-r has been proven many many times to hold 400+whp on stock internals as well. goodluck on your decision.
