    this question would have been asked a lot
    But I don’t know much about doing it
    I’m wanting to fit a LS3 in my VH SLE
    So I want know what I need to do to convert it
    What parts I need what transmission to run.
    What break system
    What I need to do to the electric side of things
    What conversion kits to get
    And help would be great
    Cheers

    Engine, harness (will need to be modified), ECU, pedal (if staying with FBW), Tuff Mount engine mounts, Pacemaker headers (tri-y is easiest to fit), trans can be up to you depending what you want i.e. factory VF manual or auto (i went with a TH400 in my LS3 VK, fits straight in) plus a tail shaft to suit, VN to VS EFI tank so you can run a Walbro in tank pump out to a Corvette style regulator and dead head fuel line setup, will probably need a built diff, VS brake booster with VT master cylinder and VT front brakes, standard wiring will need to be modified to get everything working properly, all pollution gear will need to be fitted (carbon canister, cat converters). That's keeping as much factory equipment as possible for engineering, custom gear will mean more work from an engineer, and will end up costing more. Call and speak with an engineer before you start if you want it registered and legal, they'll tell you what will work and what wont. Work out a budget as well, then double it for a realistic figure. The more you can do yourself the more money you'll save, but know your limitations.

    Dropping in a 304 injected motor will prob be easier and cheaper with an excellent result. Not as much torque as an LS but will still be great to drive.
