Looking at getting a P5 a few quick questions.

I was looking at getting a Miata or a used Mirage, but I was offered a very good price on a P5 from a member of my Mazda local club.... my question is this: I see a lot of turbo manifolds for the 1.8 miata that also fit under protg. Do they fit the 2.0 block as well (more importantly are the ports the same and not just flange/bolt)? If not anyone know of a cheap mani for it (not worried about possible crack, can weld)? The first thing I would be doing after determining engine health and repair is a low boost turboh. Also would be replacing some suspension components as the car has over 200k on it. I'm looking at some hardrace/ultraracing parts for suspension/chassis ; do the p5's/protg 4 doors of the same generation share the same suspension components? Chassis code is the same, just want to make sure. Thanks.

Thanks!
