Not worried about that...researched it before. gonna build an airbox IN the cowl area...no scoops it will pull air through the grills used originally by the heater. Im more worried about the differential. Ive heard 300 zx diff r stronger but i like usin nitrous on my 3800 and i think its close to 550 wheel trq on the bottle. mabye i should plan on a Jag or 9 inch ford to begin with.
