    Engine swap questions?

    I have two running 2008 RXPX's that I want to swap the engines from one to the other. I have not swapped a 4 tec engine for a few years so need a little help with it. What will I need to remove from the engine in order to be able to get it out of the hull? Trying to remove the minimum parts possible and still be able to swap the engines. Are there any special tools that I will need for the engine removal and reinstallation of each engine? Thanks

    the swap is very easy,
    remove the driveshaft,
    disconnect hoses and wire harness
    unbolt motor mounts,
    lift out engine,
    reverse order for reassembly.

    I remember it being a little more involved than that. Wasn't there a tool need to disconnect C-clip the driveshaft and also some alignment tools needed when reinstalling the engines? Also doesn't the coolant need to be drained? Does the pump housing need to be removed? Can anyone offer a step by step of what needs to be done and what tools are needed? Thanks

    of course you need to drain the coolant but if you are doing an engine swap the basic knowledge of that is expected. You just pull the hat back and pop the clip, no special tools needed. Ideally you'll want to use an alignment tool when reinstalling the engine but other than that it is very straightforward.

    So I shouldn't have to remove the supercharger, intake or anything like that in order to get it out? I can't remember, does the pump housing need to be removed?

    You have to disconnect all the electrical connectors to any block sensor, and I don't think you can get the motor out without taking off the intake manifold. Most of us disconnect all the sensors to the block and rear sensor bundle, remove the screws holding the intake manifold to the head, pop the throttle cable off the tb, then put the intake manifold (still attached to fuel hose) in the footwell. If you disconnect the sensors correctly, the intake manifold can sit in the footwell out of the way and makes swapping blocks very easy.
