ALright, I have a 1993 240sx, with an s13 sr20det. How hard would it be to put an S14 sr20 in it? Im thinking of buying the whole front clips, so that may help... thanks

Engine Cost: $2,500-3,500
Install Cost: $1,000-2,000
Modified Horsepower Ceiling (stock internals): 350-450hp
SR20DE-T (S14) [more info]

Redline: 7,500rpm
Good: ~250hp stock, usually very low mileage, better condition than s13 or s14 engines (in most cases)
Bad: 6 speed tranny is somewhat weak, so if you plan to increase the hp much you want to swap it for the ka tranny or an s13/14 tranny, VVT can be an issue when modifying heavily, aluminum block
Engine Cost: $5,000-6,000
Install Cost: $1,000-2,000
