first of all, i can gaurantee you wont put together a rear mount tubro for a stack, its not going to happen, youll have 1k between the turbo and injectors, not to mention all the pipe, the fitting, return pump, fuel pump, FMIC, wastegate, and bov etc. we just got finished rear mounting a grand prix gxp with a master power t70, and i bet he has about 3k wrapped up in it. and still hasnt paid for all the labor yet.
so with that said. your 1k budget is not going to happen. even if you bought a cheap emUSA turbo for 275, u still need a flea bay innercooler, and all supporting mods, and a TUNE!!!! you cant go cheap their.
im sorry to come down so hard here, but its just not realistic. im sorry for being a dick.
