Don't till me your looking to trade your hatch for a d15b1 civic with a cripple turbo set up.
But somehow you do decide to do it. Dsm injector are the cheapest in the market. P28 is a Vtec ecu if I'm not mistaking. D15b1 isn't vtec thoug you can tune the ecu or chip it. Chrome and hondata is a piggyback computer for your ecu.

If I were you I would stay away from this kind of things. He prob f'ed something up that's why he quit on the build
