EVO X Gaskets

BC gaskets are made in Japan and deliver the ultimate sealing capability even at extreme boost pressures. They feature Individual die cut layers of stainless steel with superior consistency compared to other leading gaskets. These inferior brands are constructed with beads that are too high profile, are prone to fatigue and lose spring effect and consistency of sealing pressure in a relatively short period of time, which results in leakage. BC gaskets are pre-coated stainless steel with a consistant 0.2 micron layer of Nitrile rubber that completely fills the cylinder head surface. Even a newly resurfaced cylinder head and/or block has a surface finish or roughness between 10 to15 microns and this Nitrile rubber completely seals the surfaces at operating engine temperatures, unlike the FKM type which is not suitable for filling the surface roughness because the material’s heat resistance is too high. Basically, the FKM does not melt to fill into the surface roughness to provide the proper seal.

BMW M3: Pistons, Rods & Motors

The HPF stage 2.5, stage 3 and stage 4 engines are built to handle horsepower in excess of 1200rwhp. These motors have virtually zero taper, zero ovalization and the cylinder walls and ring clearances are set to within .001-inch using state of the art SUNNEN machines. Every engine is torque-plated prior to boring and honing to eliminate ovalization that occurs when the head is torqued down. There is no difference in the build between these stages. These builds are designed so that the end user can upgrade to a higher stage at a later time without rebuilding the engine.

JE Pistons
Honda B-Series VTEC Pistons

JE Pistons has announced the expansion of their Honda product line to include purpose-built drag racing pistons for all Honda B-Series VTEC engines. The new pistons are forged from high-strength 2618 alloy and feature an E85 and race gas friendly 10.0:1 compression ratio. The overall design has been adjusted to meet the needs of today’s high horsepower Honda drag race engines. This includes a thicker crown, increased top ring land and a shorter, stiffer wrist pin. The piston crown is a flat top design that is ideal for optimal flame travel.

ARP Fasteners
RB26 Head Studs

Replace your stock head bolts with ARP heavy duty head studs for added durability. The ARP stud design helps the head and the block equalize the pressure better thereby creating a much more even and consistent seal under high compression and boost. It is recommended to replace the head studs/bolts with a new set if the head bolts are ever loosened due to metal fatigue. Reusing old and possibly warped or stretched head bolts/studs will sacrifice the seal between the head and block and may cause head gasket leak. This is a great an easy upgrade when doing an engine rebuild or building a race motor for popular vehicles including: Nissan, Honda, Mazda, Toyota, Scion, Subaru, Mitsubishi and more.

VQ35 Sleeves

JGYCustoms has now decided to take the leap into the VQ market after years of SR20 development. With the 350z and G35 performance market steadily increasing the master engine builders at JGY have helped to develop a revolutionary new sleeve for the VQ35 engine. From the factory, the VQ35 engines are an open deck design which is great for N/A setups. When going to a turbo application, everything changes. The JGY VQ sleeves completely eliminate the open deck design. JGY VQ sleeves feature a factory size bore but can be taken all the way to 103mm. These are the sleeves to have if you are looking for performance from your VQ35 engine.
