I was wondering which kit would be the best and be the safest for a d16z6 engine. I'm leaning more to zex kit because of the ease of intallation. The engine is basically stock with intake and exhaust and have about 150,00 miles on it. With the hig millage on the engine would it be okay to run nos or would i end up blowing the engine within a month or so? any opininion? Also planing to do a swap near the future not sure what engine yet to swap thinking of gsr right now, would this kit be a able to bolt on to the motor no problem??
