MOTEC EFI 3.8L SLIDE VALVE ENGINE BUILD

Day 1, how the 964 3.6L engine arrived.

Day 1, how the 964 3.6L engine arrived.

First, the engine is completely disassembled and thoroughly inspected.
Any parts in less than desirable condition are scrapped, while the rest are restored or replaced.
Anything kept from the original engine is cleaned in our heavy duty parts washer before work begins.

The heads getting cleaned up!

Twin plug heads being worked to maximize flow for high performance numbers.

The engine build includes increased displacement to 3.8L using Mahle pistons and cylinders.

The engine uses Pauter rods, calico coated bearings, titanium retainers and racing valve springs. A GT2 engine oil pump handles the high performance demand with ease. (ENG 996 107 007 94)

For top end power, uses 993 RSR Mechanical Rocker camshaft set and Solid Rocker Arm Valve Control Conversion (ENG 993 105 043 99).

Engines running at higher RPM tend to float the valves resulting in power loss. This set with performance valve springs are a must for any hard driven engine or with camshaft upgrades!

The engine also uses our 964 - 993 RS Solid Hub for Air Cooling Impeller Fan Alternator Drive. (993 106 051 80 PMS)

This converts to single belt drive, with our RS/RSR type 964 engine crank pulley (964 102 050 SBC PMS)

Engine suspension bracket (930 375 011 RSR PMS)

New wiring, ignition, and fuel components ensure top reliability for years to come.

This engine uses the high performance slide valve system with electronic fuel injection.

EFI with MoTeC management gives complete control over tuning!

MSD twin ignition with MoTeC M84 management system directing the show.

The high performance 3.8L is finished with 1.75" headers and RSR sport muffler.

365hp never looked so good!
