    Default 20V in a Seca

    I was wondering how hard would it be to install a 20V into a Ae93 Seca SX. Would everything just bolt up? Will I need the car to be engineered for registration after the engine is dropped in?

    Any comments welcome.

    peice of piss...engine mounts will fit and so will the driveshafts. you will just need to worry about

    wiring
    exhaust
    power steering hose

    thats basically it from memory..

    yes you need engineering cos that motor was never released in Aus.

    do a search im sure its been covered many times before, i think the whitzl may have done a guide on what needs replacing/swapping between motors.
    but yes its a relatively easy swap, and you will need engineering

    Lol. Easy for Karl, AK, JP or Sideshow to do the wiring. But hard (read impossible) for me to do it (but then I'm not into that kind of thing. But it is almost "Drop in" as far as the mechanicals go.

    Or, buy someone else's conversion and drive that. Or buy a second hand smallport and build it to the specs you want and drop that in. Both options should be cheaper than what you are asking to do.

    the wiring is easy even for me in an ae93{i have one}. Harder in ae82, but i still got them to run, just need the schematics and take your time.

    is only my prefrence, but the GZE is a better swap from doing both and driving both. The gze is much better for street driving duties in my opinion, but that said, we all like diffrent things.
    either the 20v or the GZE are a straight forward swap into an AE93. more an engine change than a conversion.

    Thanks for all the info.

    I'm just hoping the deal with the Seca SX comes through. One owner, the body looks good, the red still looks good but the engine has done 300K km. I was thinking of the engine is tired or blows up I'll do the swap.

    I've also been quite partial to a GZE.
