It had to be able to handle the most power ever produced by a GT-R, and 2. It had to make that power reliably. Our Engineers chose billet aluminum because of its superior strength and excellent ductility. Each block is CNC machined in America from one solid piece of billet aluminum. This material’s ability to withstand the extreme pressures and heat produced by 2500+ horsepower is unmatched.\u003c\/em\u003e\u003cbr\u003e\u003cbr\u003e\u003cem\u003eThe Pinnacle of Performance:\u003c\/em\u003e\u003cbr\u003e\u003cem\u003eThe Alpha Performance R35 GT-R Billet Block is simply the best. Whether it is in the Ultimate GT-R race car, the World Record setting Alpha G, or the most celebrated street car ever, and back to back “King of the Streets” Champion AMS’ Alpha Omega, our VR38 R35 billet block is the centerpiece of winning. The Block features alloy steel main caps with splayed bolts for better load distribution and skirted block design for the highest levels of crankshaft support. The cylinders feature custom designed Darton© sleeves and extra thick walls to withstand extreme cylinder pressures, allowing for an increase to 4.0 liters of displacement. This increase in displacement allows for quicker spool times and better low end torque over the standard 3.8 liter factory engine. If you are building a Nissan GT-R to compete against the world’s best then the Alpha Performance VR38 R35 GT-R Pro Billet Series Block is where to start.\u003c\/em\u003e\u003cbr\u003e\u003cbr\u003e\u003cem\u003eUltimate in Efficiency:\u003c\/em\u003e\u003cbr\u003e\u003cem\u003eAt the power levels this block is capable of producing, extreme heat can rob the engine of horsepower. This is where the billet aluminum block material comes into its own. Billet aluminum’s excellent thermal dimensional stability can take all the heat that you can throw at it and asks for more. We’ve always prided ourselves on having a tried and true engine program. Our engines have powered many of the world’s fastest R35 GT-R’s with 7 second quarter mile passes becoming a regular occurrence.

Installing a stroker kit increases engine displacement, for example, from 3.8L to 4.1L, allowing the engine to produce more power. The longer stroke enables a greater fuel\/air charge, leading to improved torque, particularly in the lower rev range. However, the extended piston travel may limit the engine's ability to achieve high RPMs, which can reduce overall responsiveness.
