ALPHA Performance 4.1L Stage 2 Crate Motor | 2009-2021 Nissan GT-R (ALP.07.04.0016-1) AMS Performance

2009-2021 Nissan GT-R 4.1L Stage 2 Crate Motor by AMS Performance

By adding a billet stroker crank to our already potent 3.8L VR38 engine we have raised the bar once again. When

changing to larger turbos there is always a tradeoff of low end grunt for increased top-end power. To remedy this, our 4.1L Engine

increases displacement by 8% which adds horsepower and most importantly asphalt shredding torque. The increased stroke coupled with an

elevated compression ratio produces more low end torque which considerably reduces turbo lag and improves boost response. The Alpha

4.1L achieves a 300-500 rpm improvement in turbo spool up time when compared to its 3.8L counterpart!
