The Ultimate block-building combo for DAZA/DNWA, etc, this kit includes everything you need to build the engine block for High boost (power output)
i-Beam steel connecting rods 2.5L TFSI engines with chain (EA888) are designed for an extreme performance (275HP/Per CYL). This will increase the performance of your Audi TTRS/RS3.
In order to optimally lubricate the piston pins and protect the engine parts from abrasion, the connecting rods come with an additional drilling All JDY connecting rods are precisely angled and tested. JDY offers ARP2000 connecting rod bolts with their Conrod kits. Please note that this kit comes with ARP Age 625+ bolts.
The Audi 2.5L TFSI TT-RS pistons are made by Diamond Racing USA. They are built as tough as can be to withstand the vigorous demands of racing. No matter how much boost pressure you are running or how high you are revving, these pistons will take it and ask for more! Check the individual features for your application below.
This Kit was designed for drag racers or street racers, running on high-boost engines, that need more clamping force and tensile strength than the ARP2000 Stud Kit can offer. These are 15% stronger than ARP2000 and have a 55% increase in tensile strength over the OEM torque to Yield (TTY Bolts) !!
Due to many “head lifting” issues on Audi engines running in excess of 25 PSI, a stronger stud had to be custom-made to meet the demands of today’s top engine builders and racers alike.
These studs are made from vacuum-melted alloy steel with sufficient chromium and carbon to achieve the high hardness and superior strength Like most high strength, quench, and temper steels.
This material is easily contaminated and subject to stress corrosion. It must be kept well-oiled and not exposed to moisture. Recommended for applications boosting higher than 30 PSI.
Note: The nuts and washers included in this kit still utilize premium grade 8740 alloy as only the stud is subjected to increased pressure Each kit includes a complete set of L19 head studs, nuts, and ARP Assembly Lubricant.
An absolute MUST for all engines that run with increased charge pressure! ARP is the market leader in this field and offers you stud bolts for the engine block made of 8740 chromoly steel with rounded thread. These are up to 30% stronger expansion steel than the stock bolts. With us, the kit comes complete with the side mounting bolts for the main bearing blocks. Here again, high-strength ARP bolts are used. Quality and safety are guaranteed!
