Precision Turbo's Drop-In MK7 Golf Turbos Are Rated for 575 and 700 HP

The MK7 Golf R and GTI have been the default fast VW for a decade, and the stock IS20 and IS38 turbos have been the default bottleneck for nearly as long. Precision Turbo and Engine now has a pair of answers. PASMAG reported on August 18 that Precision released Stage 1 and Stage 2 turbochargers for MK7 Golf and MQB applications, rated for up to 575 hp and 700 hp.

Both share the core hardware: Next Gen CEA compressor technology, a high-flow 56mm CEA turbine wheel (65mm inducer, 56mm exducer), a water-cooled dual ceramic ball-bearing cartridge and an investment-cast HK30 stainless turbine housing. Installation accessories and a blow-off valve come in the box. The wastegate actuator is sold separately.

Stage 1: the stealthy one

The Stage 1 uses a 50mm compressor wheel (50mm inducer, 69mm exducer) inside an OEM-style IS20/IS38 housing and compressor cover. Precision calls it a direct drop-in replacement with no adapters or modifications, and it works with OEM-style turbo inlets. For the owner who wants a big jump in power without replumbing the engine bay, that is the appeal.

Stage 2: the big one

The Stage 2 steps up to a 56mm compressor wheel (56mm inducer, 76mm exducer) in a ported-shroud cover with a 3.5-inch inlet and 1.8-inch outlet. That bigger inlet means a matching intake. Precision says customer field testing of both versions is complete and published a Dynojet chart for the Stage 2.

The fine print

Both turbos are sold for off-road use only and are not legal on public roads, according to the announcement, and they carry a one-year warranty. Pricing was not published. Power ratings are what the hardware supports, not what a bolt-on car will make, so fuel, tune and supporting parts decide where any car actually lands.
