Ross Racing Forged Pistons to suit Nissan TB48 These are a custom piston made by Ross for Spool Imports. Pistons are available in: Compression Ratio: 9.0:1 Bore Sizes: +0.5mm Pistons come with rings, gudgeon pins and pin locks Forged 2618 Tool Steel Pins Ross Racing Pistons: All ROSS Racing Pistons (since 1985) have been forged from 2618 billet bar stock and have been heat treated and aged to a T61 condition (2618-T61). 2618-T61 is the material that is used when fatigue resistance and durability are of prime importance by all premium racing piston manufacturers. This material has less than 1% silicon particulate content. High silicon content pistons (forged from 4032 or MS75) will not stand up to the most extreme stress placed on many racing pistons. If a crack starts to form in a high silicon piston it will continue until the piston experiences a catastrophic failure. Simply stated, adding sand to the aluminum only makes it more brittle. In the rare instance of a 2618-T61 piston cracking, the crack will continue to an area where the stress is not as great and will then stop. Another advantage of 2618-T61 over the high silicon pistons is the ability to keep its shape under extreme pressure and high RPM's. "Skirt Shrinking" is not a problem with ROSS Racing Pistons.

The TB48 is widely being discovered as a platform to produce significant power. For this reason, we developed a 5.2L stroker kit for the TB48 combination. The kit consists of our Nitto/CP pistons 100mm/+0.020" bore size. These pistons are cut from low silicon content 2618 material. In addition, the pistons are complete with Nitto custom specifications, PVD rings, 9310 gudgeon pins, accumulator grooves and friction reduction grooves. The connecting rods are our robust I-beam design. Made from double melted forged billet 4340, this connecting rod features a stout I-beam design that has proven time and again to be capable of holding considerably high power. These connecting rods come with 7/16 ARP 2000 rod bolts as standard, with the option to upgrade to Custom Age 625+. Completing the kit is the 4340 billet crankshaft in 108mm stroke. This crankshaft has been purposely designed with strength and high power applications in mind. The crankshafts are an immaculate piece with precision manufactured knife edging to reduce weight and cut through crank case oil mist with ease. This enables the crankshaft to rev freely and easily.
