1995-1998 Porsche 993 engines can be installed in the 964 chassis. We sell a dedicated wiring conversion harness for this or can modify or make a new 993 DME harness. Please enquire as to pricing.
The 1996-1998 Varioram intake can also be used however the retractable spoiler mechanism interferes with the VarioRAMand must be replaced with a fixed tail or modified to fit. A good choice is an RSAmerica-Carrera style tail or a ducktail, depending on customer preference.
This conversion can be done by replacing the engine with a 993 engine or by replacing the intake, electronics, etc. on a 964 with that from a 993. The VarioRAM intake makes approximately 20% more torque from 2500-5000 RPMs and is a nice upgrade, though the factory 993 electronics can get pricey.
