Type RA Short Block Motor, Fuji Racing Head Studs & Engine Gasket Kit Package

Subaru Impreza WRX STi EJ257 GR/GV 2007 To 2014
Subaru WRX STi EJ257 VA 2014 To 2018

Identical to the earlier EJ257 so direct fit for all EJ25 turbo subarus however The difference with these blocks is the better-designed pistons.
The crown on the pistons are between 1-2mm thicker than the earlier pistons, the wrist pin supports have also been improved with added strength.
Pistons are also manufactured by Hitachi rather than Aisin, and more ductile has been added to the alloy to help reduce cracking/fracturing

This package also includes Fuji Racing 11mm Head studs and a car-specific Genuine Engine Gasket Kit. This is a perfect Drop-in setup for owners with simple bolt-ons like exhaust, intercooler, and induction kits. Will suit most builds up to 380-400BHP
