Mahle 3.8L Piston & Cylinder Set 964/993 - (11.8:1) 102mm Bore/107mm Sleeve - Slip Fit - Narrow 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. These are 107 mm in size so are slip fit and do not require modifications. 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.

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 and part# FVD99361810 or FVD99361870 for 993 models with this kit. 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.

For 964 Models: This set is made to be used with the narrow connecting rod eye of the 993 rods. You can use 993 rods or have your 964 rods machined, but we highly recommend using the Carrillo Rods which are tailored to this application, part # FVD10397503. If you would like to use your 964 connecting rods, send them to us and we will have them modified to the narrow rod eye spec. like the 993. Please order our part # 000 300 207 and mention that you will send in the rods to your sales person. Modifications are done in Germany.

Please note: 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.
