Mahle 3.8L Piston & Cylinder Set 964 - (11.8:1) 102mm Bore/109mm Sleeve - Machine Fit - Wide Rod

Description

The 11.8:1 compression will provide you with more acceleration than kits with 11.3:1 compression. We recommend more aggressive cam (maximum valve lift (TDC) of 2.1 mm). Pistons have very deep pockets for use with RSR valves. This kit is ideal for track use but can also be used on the street, it will add 35+ Hp (depending on your additional modifications). This set will also provide higher torque in the lower rpm range but is more octane sensitive than an 11.3:1 set. The 109-mm size means that the cylinder housings / case must be modified / machined on non-RS models. If you have a European RS Model, these would be slip fit. This kit also requires 6 Qty. larger O-rings, part # 96410440180 and 6 Qty. larger base O-rings, part # 99970502341

Mahle pistons are forged for substantially higher and more uniform strength over pistons that are cast. Mahle cylinders are manufactured from ST52 steel which has extremely high thermal resistance, they are Nikasil coated which reduces wear and friction. We also have the piston rings (sealing and oil scrapers) pre-installed to ensure reliability. Each of our Mahle Piston and Cylinder kits are complete and ready for installation. We also recommend using our high compression 3.8L software, part # FVD964618XX for 964 models. Just specify that you will be running this set when you order the software.

FVD Brombacher has a tradition of utilizing and offering the finest German manufactured engine tuning products. Those high standards naturally led us to the Mahle brand. Since 1984 we have been developing engine tuning packages that offer extreme performance without sacrificing reliability. We achieve this by collaborating with Mahle in Germany to manufacture the pistons and corresponding cylinders to the same tolerances. This ensures tight factory like clearances, factory quiet operation, dramatically reduced wear on the piston and bore with performance and reliability to match. Many of our competitors use one type of piston with another type of liner. They may advertise no compromise, but when your build demands performance there is simply nothing better in the industry than this Mahle GmbH set.

Please note: This set is made to be used with the wide connecting rod eye of the factory 964 rods or a set of Carrillo rods like part # FVD10397502. Carefully read our technical information before installing the parts. Piston rings and piston pins must not be modified. Modifications of any of these parts will void the manufacturer's warranty.
