i agree with Lee, simply because theres 3 or 4 swapped 240s around town one of which i helped with the swap. when we swapped the motor out the garage looked like F&F. we had an sr20det on a stand, and about another 6k in fmic, piping, exhaust, ebc, afc, turbo timer, downpipe, test pipe, etc etc.
we took out time doing the swap even though we ran into a couple snags, but got it done. its been on the road reliably for over 2 years never had a problem. until a month ago his slave cylinder went out while we were cruising. and some kid that was with us just happened to have a slave cyl. for an sr! imagine that! anyway, it seems like a lot of guys (or girls) just throw their conversion together, and thats where the reliability issues come in. but if its done right and maintained it'll be just fine!
