Which GT4?
Where is your oil filter?
The ST205 & later ones probably won't because the oil filter was relocated to the sump to allow for a bigger turbo, manifold, dump pump. I think the MR2 one is different too (but only because of the position)
The earlier ones I've heard are a straight bolt on.
Just remembe to keep the boost down if you're not going to open up the engine & replace bits,
otherwise you will be replacing bits.
