This is a brand new set of Brian Crower Stage 2 Turbo Cams for Toyota 3SGE/3SGTE 2.0L Engines found commonly in the Toyota MR2, Celica All Track, and other platforms. Stage 2 - These are a plug and play 264/264 cam for the 3sgte that do not require aftermarket valvesprings and retainers. You can drop these cams into your engine using stock valvetrain and stock cam gears, they are a direct replacement. They have a short duration for well behaved street manners, and they have a slight lope at idle. They are a perfect all purpose camshaft. This cam is perfect for stock to mild turbo setups. This cam will shift the powerband slightly higher in the midrange where it would better supply the turbo with air than a stock cam. If you are going for big power with a large turbo, we reccomend using a larger cam than this. If you have any questions please email or call us so we can help you with your decision. This cam would be perfect for a Turbo B16 that is looking to pick up more power per pound of boost. This cam behaves well on the street, and does not sacrifice any drivablility. Brian Crower is a fairly new company in the Cam and Valvetrain industry, but has quickly made a name for itself for providing quality parts at a reasonable price (a concept thats hard to find in today's market.) We have tried Brian Crower Cams and Valvetrain on several applications at our own shop and they have proven themselves to be well worth the money every time. We suggest Brian Crower Cams and actually use them in some of our very own cars.
