    Default 240SX LS3 Swap

    A nifty project, but tt would be nice to see the budget - hours and dollars.

    That engine does everything! I'm convinced you could put one in an original Mini Cooper, keep it front wheel drive and it would still weigh less than the engine that came out of it.

    An LS3 240 is one of the most fun cars I have ever driven both straight and sideways .

    The Chevy CARB legal (1995 or older chassis) crate motor is a very cool thing indeed. Makes me think of cars to put it in which there are a few good options from a performance standpoint (lightweight, independent 4 wheel suspension RWD)

    Basically I would think it would best for a street/track fun car in:
    FC, FD RX-7
    Miata
    240sx
    300zx
    240Z etc.
    E36
    Maybe a Starion if you want to be weird.
    A Merkur XR4TI to be really weird.
    Isuzu Impulse....

    Still would not be cheap in $$ or hours spent no matter what direction you choose on a swap car. A used C5 Z06 looks pretty good for the $$/performance ratio comparatively.

    I will be going either LSx or L33/LM4 in my 240SX, and I'm now under 2200lbs. After the cage gets built, more like under 2300lbs but still 500lbs lighter than their car.

    I'll gain something like 60-70lbs in engine, lose some weight by going to a smaller clutch assembly, and gain nothing in trans because I'll be running a stock car dog box.

    SR20s are expensive to properly build- my estimates are about $11-12.5k for a 400+whp, reliable build using quality products. That's with a tuned factory ECU, btw.

    I can make 400+whp out of an LS-architecture engine with flexibility to make much more, while not worrying about turbo reliability problems and still running 91 octane- for under $9k, including standalone engine management with data logging and traction control.

    You don't want to see how much I've spent, or my hours. So much money into a chassis with MacPherson struts...

    You made me add it up.

    Definitely into the five digit range on the build cost. Hours- four digits.

    My car still has less than 150whp. Then again, since '04, I've put a water pump and an MSD Blaster in it. Other than that, I haven't even taken the valve cover off in ten years.
