I'm trying to see if there is any interest for a set of brand new Mazda 99 twin turbos with Efini y-pipe. These are the turbos that make 280 hp on the jdm 99 rx-7. They have the abradable seals on the compressor housings, which wear to the turbo and improve efficiency. Again these are brand new units, not rebuilt ones. The y-pipe is all metal, unlike the stock one which has a plastic crossover tube. The two sections bolt together so they won't be prone to pop off or crack under boost. The bung for the blow off valve is also flush with the inside of the pipe, where as the stock y-pipe has it protrude slightly inside causing restriction. The pricing I am looking at is $3500 shipped for the combo. I've seen other places selling the turbos alone for $3599 plus shipping and the y-pipe for $225 plus shipping. I need 10 sets. Let me know what you think.
