The 'Circuit' Series of engines is based on our many years of road & competition experience and what mix of performance enhancing options really do work and are cost effective. For the different engine types used by VW, Audi, Seat, you can see our recommended packages for a complete engine with alternative capacities, cylinder heads and cams. Also shown are other recommended components where appropriate to the power output potential.

As explained in Engines General Information, engine prices are 'on exchange' Outright purchase is available at an extra charge
After fitting & running in for about 2500 miles, you can bring the car back to us (booking required) for an 'on the house' check of the installation and a rolling road power check.This invitation also applies to DIY self-fit engines.

Please Note: quoted BHP figures are conservative and 'at the flywheel' expectations. True outputs will be dependant on the mileage on the engine, ignition & fuelling setup and ambient air temperature at the time of testing.
