Our (RW1000) EJ257 Stage 5 Short Block takes a more aggressive approach with the use of Manley Turbo TUFF I-Beam Rods, RW/Diamond Forged Pistons with Lateral gas ports and upgraded oil rings to control oil blow-by at higher boost along with our Closed deck process. These components provide piece of mind for our power hungry inner-selves!
We start with brand new OEM STi Block Halves and Crankshaft so our blocks are sold NO CORE DUE. We take the new halves and run them through a hone to make sure that the walls are sized perfectly for the new Forged pistons. We then assemble the short block in our Engine Clean Room and built to meet your specific need. There is no "one size fits all" configuration. Our performance rep will work with you to get details as to your performance demand, driving style and boost level.
Once you receive your block, it will be assembled and ready for the long block assembly. We offer several add-on options to simplify the build process so please be sure to check out the options listed below. We know that selecting the right short block to meet your needs to key to your build so we insist that you contact us with any questions so that we can be sure to provide you with the very best block configuration.
Option for Sleeving - Our Darton Sleeve Process starts with our In-house partnership acquiring a Haas VF3SS CNC and a full set of Darton iron Dry Sleeves. The process removes the complete factory bore and replaces it with Ductile Iron goodness! Once positioned and pressed into place we finalize the optimum bore size for your application in a Sunnen SV-10 and finally back to the CNC for a finished Stepped Deck surface.
***All components should be stocked, however expect a minimum of 6 weeks build time as each block is built to spec. Please call for ESTIMATED TIME FRAME***
