Conversion Details

The Turbo Technics Kit was supplied in two different types. The VW1 & VW2 kit. The basic difference between each kit was that the VW2 kit was referred to as the “Full House” conversion, which essentially produced more overall power than the VW1 kit. Here we will concentrate on the main kit VW1.

With each VW1 kit fitted the following Items were changed or modified:

Pistons— machines to Turbo Technics specification to lower the compression ratio to around 8.3:1. this was achieved by removing the raised lip on the piston crown, and then enlarging the piston bowl and centralizing it in the centre of the piston.

Head Gasket—a special Turbo Technics head gasket was used to replace the original VAG item. The Turbo Technics head gasket helping lower the compression, and also prevent boost leakage between the head and the cylinder and premature head gasket failure.

Exhaust Manifold—Changed for a specially cast Turbo Technics manifold. This was needed to carry the Turbo. A special down pipe manufactured again by Turbo Technics was also used to link the Turbo to the exhaust system. The down pipe incorporating a bell mouth flexi-joint arrangement.

Turbo—A Garrett T34/35 turbo with double circlip arrangement on the Turbine shaft was used. The turbo being built to Turbo Technics specifications.

Distributor—A turbo technics modified distributor was used to replace the standard item, with a modified ignition curve and vacuum capsule to retard the ignition when on boost.

Metering Head—The metering head was machined by Turbo Technics to allow more fuel to flow when on boost. This however did make the car very uneconomical when used– expect around 17 to 20mpg average per gallon !

Intercooler—A front mounted intercooler was mounted in the place of the oil cooler, the oil cooler being relocated in front of the radiator. Pipe work to link the turbo, and inlet manifold was also provided.
