Default Attn:Legacy turbo kit drivers, didnt someone do the kit w/out changing the water pump

I am asking just that. I remember reading somewhere that someone had done the setup without swapping for the Legacy turbo waterpump. I ask this because this is the second time around for the install and I would like it if I could skip that step. It would be so much easier to use the same pump and not have to remove the timing belt etc. I think Someone stacked some gaskets in between the non-turbo side manifold to make it clear the stock pump. Anyone have any clue what I am talking about?

swap and N20. gone. : (


Not really sure if this is what you are looking for but I used the stock EJ25 waterpump on my EJ22T. It works fine without having to use different gaskets or anything.

the water pump from the legacy turbo goes at a different angle, and has to clear the different shaped manifold. I think someone made more space for (the stock RS pump) to fit by putting extra gaskets in. The stock RS pump goes down and the Legacy one goes to the side. I think it is different on yours.

I don't know that anyone has done this with stock Legacy headers. It might work with the Cusco or other aftermarket header.

Putting multiple gaskets on one side only would be bad - you would be mounted crookedly. And you would have to add about an inch of clearance, because there is about a 1/2" collision with the thermostat housing, which is plastic, so it needs to more than just clear it. That also affects all of your other geometry - whether a spacer is needed to clear the head with the up-pipe, where the turbo lands...

It is quicker to change the pump than it is to figure out a way to avoid it.
