Ryder Racing Engines

 The Ryder Racing Stage 1 short block “The Daily” is perfect for the lightly modified car used as a daily. As everyone has seen the Subaru engine is prone for piston ring land failure and bearing failure, this can be as a result of oil starvation, excessive blow by or poor factory clearances.“The Daily” utilises your OEM STI Short block (EJ257) case halves (subject to condition), your rods are removed and crack tested, shot peened and fitted with ARP2000 bolts. Pistons are upgraded to Manley Platinum forged items much stronger than the factory items. The case bores are machined to 99.75mm to ensure correct fitment of the Manley pistons. The block is measured, balance and assembled using a new salt bathed Nitride Treated 2.5L STI crankshaft which is matched to King main and rod bearings. Clearances are double checked and the cases are bolted with new OEM case bolts and Threebond 1215 as per Subaru standards.

The Ryder Racing Stage 4 Short Block “The Racer” starts with machining your EJ255 or EJ257 case halves ready for close deck inserts. This creates the close deck block similar to the old and rare RS Turbo blocks. Small passages are drilled allowing coolant to flow to the deck surface while maintaining a solid deck.
The deck surfaces are machined to a perfect flat ready for your heads, next the bores are honed to 99.75mm for Manley Turbo Tuff Pistons which have Moly skirting and Chrome Moly wrist pins. The case is then prepped for Ryder Racing 718 Series™ main dowels. The Ryder Racing 718 Series main dowel pins prevent the block from shifting and warping under high boost applications. Once they’re machined the pins are placed into these holes ready for assembly.
The modified case halves are assembled using a new Subaru 2.5L Salt Bathed Nitride Treated STI crankshaft that is matched to King main bearings. X-Beam connecting rods and ARP CA625+ rods bolts are utilized with King race rod bearings.

“The Extremist” has a potential power output 600kw, subject to supporting modifications and tuning. 

Ryder Racing has been working in the shadows for the past 2 years, after numerous calls to develop our own close deck program we were apprehensive about the idea due to the failures of other reputable designs that are currently on the market. After a short discussion with Dave P (OMD Ryder Racing's official engineer) the solution was obvious, a completely new design! We combined everything which was shared with us and combined it with our engineering and innovation to come up with all the solutions for the failed closed deck programs out there.

Where others short cut we took it to the next level, using thinner plates to save machine time and plate cost was unacceptable, we start with a 30mm plate so we can press a one piece insert into the case halves, this stopped distortion and incorrect fitment issues. Where other companies haven't seated the insert correctly which either lifted or sunk we have a unique doweling system which works along side a shelving system to prevent "floating and warping". We are the first in the world to bring such innovation to the closed deck program.

We have incorporated a coolant passage system around the entire circumference of the bore which allows any gasket type or head design making them a perfect system for hybrid engines. We are now offering drilling and tapping for OUR 14mm head studs as well as CNC drilling for our 718 Series main web pinning which accommodates our 718 Inconel Dowles
