We were contacted by Lee Malo from Advanced Technologies in Gloucester, MA. A customer with a ’07 Audi RS4 had acquired an RS6 and commissioned them to do the first-ever engine swap in the US. The idea was to build the only RS4 4.2L twin-turbo with heavy mods.
The customer wanted to rebuild the RS6 engine to push approximately 840hp at the crank, 700hp to the wheels. Therefore, the company obtained a JE piston set, Integrated Engineering rods, ARP head- and main studs plus stainless intake valves and Supertech inconel exhaust valves.
The turbos are Borg Warner 6758 EFR snails with billet compressor wheels and titanium turbines. They’ll be mounted on CNC-machined billet exhaust manifolds with hand-welded 304L stainless downpipes and fed by upgraded fuel lines, pumps, injectors, MAF and EPL engine management.
The transmission is a custom-built 01E manual with hardened gears plus a Tilton twin-disc clutch and flywheel. The diff will also be rebuilt and the car fitted with Stasis suspension, Alcon brakes, etc.
We can’t wait to see how this monster turns out and will keep you updated on its progress.
If you remember the incredible 591whp VW R32 turbo that took part in our 2010 Tuner GP (et 2/11), then you’ll be familiar with the work of Bluewater Performance from Westminster, CO.
The crew had told us they were working on some new projects, and here’s Jason Koenig’s ’04 R32 as proof. He’s owned the car since new but decided it needed to be a little “better”.
The plan was to build a flex-fuel engine capable of 650-700hp and drop the car on Bagyard air-ride. The job was entrusted to Bluewater.
We’ll look at the extensive body mods in later months but for now, the engine build included 8.5:1 JE pistons and IE rods, with Raceware studs securing the head that houses 264/260˚ Schrick cams.
The turbo is a Precision 6265B with billet wheel, mounted in a cast manifold and coupled to a 3" downpipe with 3" stainless exhaust and high-flow cat.
There’s a short-runner intake manifold connected to a Garrett FMIC by stainless piping. The fuel system uses a Walbro 255 lph pump as well as dual Bosch 044 pumps in a surge tank. These feed the colossal 1200cc Bosch injectors that are controlled by Bluewater’s flex-fuel software tune, aiding by a water/meth kit.
Looking at the spec, the R32 seems more of a racecar, yet there’s been sufficient body mods to classify it as a show car when it all comes together.
We’ll have more details on this ambitious project next month.
et 4/09. Back then, the resident of Lebanon, PA ran it on black 17” BBS RS with Aviator grey bodywork, an S4 interior and a string of bolt-on engine parts.
Since then, he’s been itching to do something different and eventually decided to embark on this unusual right-hand drive conversion.
To make his life simpler, he bought a RHD front-end and proceeded to strip his own car to transfer all the parts. This included the RHD firewall to accommodate the steering column, heater box, dash, carpet, pedal assembly and steering rack. He also needed the door cards since the window and mirror controls go on the other side. He’s also been switching the interior harness over to RHD so all the wires reach their connections.
In addition, Jason has removed everything from the bottom of the car to undercoat and powdercoat select parts. He then hopes to do an engine swap and is researching the feasibility of installing an Audi V8.
Add some Air Lift suspension and rebuilt 17" Carline CM6 wheels and we have the basis of the Passat conversion.
We’ll continue to follow the overhaul as it unfolds.
