Check Out James Dorey’s Audi quattro S2
However, Dorey wasn’t content with the idea of sending his Quattro S2 off to a garage to do the work for him. Instead, he opted to do the work himself. The crew at speehunters.com took a visit to check out Dorey’s awesome Audi Quattro S2, and the following are some of the highlights they captured.
First step – strip the car down to nothing
The original car was stripped back to a bare shell before James started preparing the chassis for the substantial makeover. With plans to run the car in the UK based Time Attack Series, a regulation-conforming multipoint roll cage was welded into the car. A healthy dose of gusseting helps them to brace the cage against the original A, B and C pillars.

Next, he updated the seating
Dorey’s next step was a touring car inspired change—he moved the driver’s seat as far back as possible in the car. This provides both better balance to the forward mounted engine, an Audi tradition, and also allows a wider field of view. A custom shifter tower was crafted to bring the gear selector back within driver’s reach along with an adjustable floor-mounted pedal box.

The radiator was moved too
On the theme of weight re-distribution, the radiator was relocated to the rear of the car. It is fed cool air from the ducting on the side windows which are drawn into a custom-built box to ensure the air is sent where it is required. Just in front of the radiator box is an ATL 60-liter fuel cell where the fuel is brought to the injectors by three Bosch 044 pumps.

Examining the bodywork
The bodywork is a mix of carbon and glass fiber composites, with the rear wing being mounted directly to the chassis to provide more effective downforce. Dorey was primarily responsible for the vast majority of the work that went into the car, save for the odd occasion where a friend could help out (paint, aluminum welding, loom, and geometry). With no budget for wind tunnel or aerodynamic simulation testing, all the extra aero additions will be tested against the clock to see what improvements they make.

Additional updates
Some of the bits you can’t immediately see are the three-way adjustable AST dampers which utilize Eibach springs and feature remote reservoirs. Stopping comes in the shape of Brembo manufactured and Audi RS-badged eight-piston front and four-piston rear brake calipers. Additional highlights include custom JE Pistons, a Weaver Brothers dry sump system, Shrick cams and a Nuke fuel rail with Bosch 1800cc injectors. Aside from that distinctive five-cylinder wail, these units have been proven time and time again to be capable of handling whatever is required of them.

Performance
The triple ball bearing Comp Turbo should allow the car to run up to 800hp, although Dorey would be happy to run a reliable 650hp whilst he concentrates on getting a feel for the car and dialing in a set-up.
While Dorey might still be putting the finishing touches to the car, it’s clear that he has put together a balanced and considered build, especially given the limited budget (time and money) he was working with.
