Our (RW750) EJ25 Short Block has quickly become our most popular Short Block for that daily driver who wants to push the daily limits of boost and HP with a safe range of 450-600awhp. The Stage 3 short block gives you performance, reliability and value.
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.
Rev Works has now included the options of our Closed Decking Process to eliminate distortion and cylinder flex in the weak areas of the top of the cylinders. Along with pinning the mains to help eliminate the flex and/or distortion of the main saddle under severe loads applied during High Boost applications.
This process starts with our In-house partnership acquiring a Haas VF3SS CNC- machining the block for our unique billet insets to form a true "Closed Deck". We even strive for perfection in closing the complete deck by creating a case bolt plug to be inserted after Block Halves have been torqued properly. Along with the RW_CD we also decided to take things one step further by pinning the main saddles. Using a 6mm dowel in 6 locations for correct line bore placement. Then we Line Hone the Main Bore to OEM Standard to use the High Quality ACL or King Race Bearings.
***All components in stock, however expect at least a 2-4 week build time as each block is built to spec***
