Needless to say,this tranforms your Altima into the most unsuspecting sleeper to ever to hit the road.Boost pressure is set at 5 psi(CVT) or 9 psi(Six speed) .

Speed Force Racing can take your stock VQ35 Altima and turn it into a tire smoking, turbocharged and intercooled,320-400WHP sports coupe, that can not only keep up but even beat, many of the sports cars on the road today. This is not hype, this is a reality! The best part about this is that you keep your stock drivability and reliability.By keeping the boost low 5, you will be sure to get a long, troublefree lifespan out of your stock motor.A key benefit of our approach to desiging this turbo system is lower cost and ease of installation. We designed the exhaust plumbing to bolt right up to the stock exhaust manifolds! This saves alot of hassle and time and makes it easy to return back to stock if neccessary.On top of that we made it easy to get turbocharged now and then offer upgrades so you can slowly build up your turbo system to the power levels you want. We also incorporated another unique element to this turbo system and that is converting the MAF sensor into a blow-through unit.By converting to a blow-through system it allowed us to use a conventional blow-off valve and vent it to atmosphere as well as being much safer for the engine.Yes, safer! By converting the MAF to be a blow-through unit we eliminate the potential of sucking in unmetered air and running lean, which leads to detonation and possible catastrophic engine failure.We also utilized a Spearco intercooler to keep the charge air temps to help maximize power and increase safety even further.
