ok where do i start? you need to reconsider some things. 1) unless the turbo engine and your engine are identical, that turbo you've got will not just bolt on. and i do hope you have the manifold as well. 2) if you have NO boost control whatsoever, then the wastegate will be shut continuously, and the turbo will be boosting to its fullest potential ALL the time. i'm sure a factory mazda turbo will not boost to 17 reliable psi, but i'm sure it will boost enough to blow your engine to shreds, and likely destroy the turbo. you're going to have to rethink that statement there- how do you plan to regulate boost at 9 psi with no boost control whatsoever??? 3) what more internals do you need other than pistons, rods and crank? and i'm only assuming that they are factory parts, because i'm sure no one in their right minds would let off an entire forged reciprocating assembly for 300 dollars. so what good is this stuff going to do you under boost? none.
another idea would be to swap in this other turbo motor that you say goes in your car. or just get another car. it gets to a certain point with some cars that the ends just don't justify the means... i mean, you're talking about possibly sinking some serious time and money into a car that at best will probably run in the upper 14s. but it's up to you... you just really need to learn some things and decide what you're going to do. and you're not going to learn them on a tech forum.
