    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

    yea also on your scale its easier to drop in the vq35de in the 240??? you might need to change your difficulty ratings. But damn good info reguardless.

    Must Know 240SX Engine Idea's and Information

    Can this please be a sticky??

    But here it goes.. all the info for engine swaps and wiring and codes for a 240SX...

    Turbo KA24DE [more info]
    Swap Difficulty: 1
    Aftermarket Support: 3
    Donor Car(s): S13 (1991+ US model), S14 (all US models), Hardbody (pick-up)
    Stock Horsepower: 155hp (157ps) @ 5600rpm *before turbo install*
    Stock Torque: 160lb/ft (22.2kgm) @ 4400rpm *before turbo install*
    Redline: 7,500rpm
    Good: cheap, fast, less work than a swap
    Bad: reliability issues in some cases when running med/high boost sustained
    Engine Cost: $800-1,500 (a few hundred more if it's rebuilt or has some parts upgraded/strengthened)
    Install Cost: n/a (everything is installed other than turbo) OR $200-500 (to install a new KA where your old KA was)
    Modified Horsepower Ceiling (stock internals): 250-350hp

    CA18DE-T [more info]
    Swap Difficulty: 4
    Aftermarket Support: 4
    Donor Car(s): Silvia (1989-1990) and 180sx (japan)
    Stock Horsepower: 173hp (175ps) @ 6400rpm
    Stock Torque: 166lb/ft (23.0kgm) @ 4000rpm
    Redline: 8,500rpm
    Good: higher redline and cheaper than SR20DET with about the same potential, iron block
    Bad: less parts support (esp in the US), weaker head gasket than SR20DET
    Engine Cost: $2,000-3,000
    Install Cost: $1,000-2,000
    Modified Horsepower Ceiling (stock internals): 300-400hp

    SR20DE-T (S13) [more info]
    Swap Difficulty: 4
    Aftermarket Support: 4
    Donor Car(s): Silvia K (japan), Kouki 180SX

    Stock Torque: 202lb/ft (28.0kgm) @ 4000rpm
    Redline: 7,500rpm
    Good: great output for the price with very good potential
    Bad: less output than an RB25 and weakest (stock) SR20DET, aluminum block
    Engine Cost: $2,500-3,500
    Install Cost: $1,000-2,000
    Modified Horsepower Ceiling (stock internals): 350-450hp

    Swap Difficulty: 4
    Aftermarket Support: 4
    Donor Car(s): Silvia K (japan)
    Stock Horsepower: 217hp (220ps) @ 6000rpm
    Stock Torque: 202lb/ft (28.0kgm) @ 4800rpm
    Redline: 7,500rpm
    Good: slightly better output than the S13 SR20DET
    Bad: VVT can be an issue when modifying heavily, aluminum block
    Engine Cost: $4,000-5,000
    Install Cost: $1,000-2,000
    Modified Horsepower Ceiling (stock internals): 350-500hp

    SR20DE-T (S15) [more info]
    Swap Difficulty: 4
    Aftermarket Support: 4
    Donor Car(s): Silvia K (japan)
    Stock Horsepower: 247hp (250ps) @ 6400rpm
    Stock Torque: 202lb/ft @ 4800rpm
    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
    Modified Horsepower Ceiling (stock internals): 350-500hp

    Stock Torque: 217lb/ft (30kgm) @ 4800rpm
    Redline: 8,000rpm
    Good: deeper engine sound, stronger than the SR20DET, more stock horsepower, iron block
    Bad: cost, replacement parts availability
    Engine Cost: $5,000-6,500
    Install Cost: $2,500-3,000
    Modified Horsepower Ceiling (stock internals): 400-450hp

    RB26DE-TT [more info]
    Swap Difficulty: 2
    Aftermarket Support: 4

    Redline: 8,000rpm
    Good: huge potential, high horsepower stock, iron block
    Bad: AWD tranny can't be used without lots of modification and custom work. TT setup can be retained, but it's much easier to convert it to a single turbo. RB25 tranny (5 speed rather than RB26 6 speed) because of clearence and fit issues.
    Engine Cost: $7,000-8,000
    Install Cost: ~$3,000 (AWD and TT setup will be in excess of $15,000 for install)
    Modified Horsepower Ceiling (stock internals): 500-600hp

    Stock Horsepower: ?hp (?ps) @ ???rpm
    Stock Torque: ?lb/ft (?kgm) @ ???rpm
    Redline:
    Good: good potential, iron block, cheap engine, when modified produces large hp numbers at low revs
    Bad: age, replacement parts availability, block is hard to find, RB20 head requires lots of work to fit correctly
    Engine Cost: n/a
