In starting with a clean slate for our VR38 engine program and developing our Titan Motorsports Billet VR38 block we came to the realization that many street cars would benefit from an upgraded lower billet main girdle. During our FEA analysis of the factory block our simulations revealed block distortion that could lead to main bearing failure and gasket failures.
A new lower girdle was designed using Computer Aided Design and analysis. The result is a product that strengthens key areas of the girdle while mating with the OEM casting, allowing the engine to withstand the abuse that the block endures while producing over 1,000hp more than the factory desired. This CAD engineered girdle is CNC manufactured from a solid block of 7075 aluminum alloy commonly found in the aerospace
industry. 7075 offers strength properties comparable to most steels while providing more corrosion resistance than some other aluminum alloys.
This billet girdle will require line boring to your engine builder’s specifications and will work with the factory 3.8L displacement or stroker applications. This design will be implemented in our upcoming VR38 billet block. Until then, anyone looking to build their own race prepped VR38 with premium parts can benefit from our experience while using the machine shop and engine builder of their choice.

Titan Motorsports releases its stroker kit for the VR38DETT engine found in the 2007+ Nissan GTR. The kit features a 94.4mm stroke crankshaft which increases the factory 3.8L engine to 4.1L with standard bore pistons, up to 4.3L with overbore pistons. The billet crank features scalloping as well as knife edged counterweights to reduce weight and increase crankshaft aerodynamics. The crank also features a 2.200” rod bearing which allows for a larger variety of bearing material availability over the factory Nissan bearings. The kit includes Carillo rods and CP pistons produced to Titan Motorsports specifications, designed for an increase in RPM range and horsepower. The pistons are available in standard bore, over bore, or custom bore to customer specifications. The complete kit including crankshaft, rods, pistons, wrist pins and rings retails for $9,995.00 and is available for shipment worldwide.

Titan Motorsports is proud to announce the all new TMS H11 Head Stud and Main Stud Kit for the GTR R35. The H11 stock dimension head studs have approximately 35% higher clamp load and the main studs have approximately 50% higher clamp load rating than the OEM studs for the GTR. Made from H11 material, a premium steel that is processed to deliver superior strength and fatigue properties. These head and main stud kits are essential for those looking to push their VQ38DETT to the limit, as the stock offerings are unable to handle the rigorous pressures produced by higher performing engines.
