CP Pistons Brian Crower I Beam Rods For WRX EJ255 9.4:1 / STi EJ257 9.0:1 100mm
Description
This is a full set of pistons, rings, pins, locks, rods, and rod bolts.
These pistons are +0.50mm (or 0.020 inches) over bore. This is often referred to as "Twenty Thou Over". Many times when an engine is being rebuilt after a failure, the cylinder walls are slightly damaged, requiring the clinder hole to be bored out. This process removes any surface irregularities from the cylinder wall, exposing a clean true surface. This oversized piston is used to make up the specified difference of material removed by boring the hole bigger. Consult with your machine shop to determine what diameter your engine will be required to be bored to, then buy the corresponding oversized piston.
We use CP Pistons here in the shop regularly, and have yet to run into any issues with them. You can count on CP to get it right, and provide you with a part that can hold up in extreme conditions. CP Pistons is one of the most trusted names in the industry, and for good reason. Their extensive shelf catalog provides the user with many of the options that you'd normally be resigned to going to a custom piston for. Their standard offering already includes Dual Pin Oilers - providing double the amount of oil to the wrist pin, radiused valve reliefs and the pin fitting final hone on the wrist pin bore. They even include an Accumulator Groove as a standard option. This provides a small pocket for the combustion gasses to collect after the first ring, reducing ring flutter and providing a better seal allowing more downward force on the piston A.K.A. - make more power. All pistons come balanced within one gram, include wrist pins at no additional charge. Brian Crower I-Beams are a great high-power rod for not a lot of money. The I-Beam construction is designed to hold up in high horspower forced induction applications. The fit and finish is really nice, and the parts are almost always available to ship immediately. It has been our pleasure to work closely with Brian Crower in the research and development of many parts in their line and we are proud to be a stocking warehouse distributor of their entire product line. If you are unsure if this is the correct rod for you, please contact one of our experienced sales reps today to help you put together the parts list for your next build!
