yeah, bet they’re pulling their hair out tuning it etc.
So nobody has info on living weapon’s build?

they somewhat embarrassingly promised regular updates…then nothing for a few months…then a blip…then nothing.

RS4/RS6 Swap
Last month we introduced this Frankenstein creation being built by Advanced Technologies, HT Motorsport and EFI Express. Customer Bryan Whitmore has asked them to swap an RS6 motor into his 07 Audi RS4 and then tweak the turbos to nudge 840hp at the crank, 700hp to the wheels.
To achieve this, the motor is now fully built with JE pistons, IE rods and ARP hardware. They have selected dual-scroll EFR turbos and are awaiting their delivery as we write. The custom dual-plenum inlet manifolds are also due in the next week.
The V8 engines oil system is a custom dry sump with all the tanks and plumbing hidden under the custom trunk floor. Whats more, the alternator and A/C unit have been mounted in the vee between the cylinder heads to make room for the turbos, and an electric power steering system has been fitted.
The specification of the motor has evolved since last month because the RS4 headlights are apparently huge, confounding their original plans for mounting the turbos. It meant they had to mount the Borg Warner turbos low at the front. This in turn necessitated the dry sump and meant they had to push the block back and down as far as possible to gain room up front for the radiator and intercoolers. In the meantime, the built 01E transmission has received a sequential shift mechanism, lightweight flywheel and uprated clutch to deal with the torque from the motor. [/b]

RS4/RS6
Continuing our coverage of this crazy 700hp RS6 engine swap into a RS4, HT-Motorsport has been moving the project along quickly. The equal-length, phase-matched exhaust runners, for example, were designed in 3D CAD to ensure quick spooling for the T4 turbos. In fact, Borg Warner supplied development hot-side turbo housings for test fitting to help confirm the design of the downpipes and turbo manifolds.
After they finish the fabrication of the downpipes and manifolds, the new parts will go through a heat treatment to remove residual stress during the welding process before ceramic coating.
The sequential shifter on the Audi 01E manual transmission required significant tunnel work, including modification of the heater housing. With shifter itself is being fabricated to look stock but will also have a quick-change feature to allow it to be swapped out for a longer version for races.

weird that they’re talking about getting dyno’d ‘before there’s snow on the ground’. Is this update from like November and they forgot to post it? Or are they talking about another year for the build? Seems like the FEB update was written befor ethe SEP update because the exhaust was supposedly all welded up in Sept…but they’re working with only one turbo in Feb. Must have been from the fall but they didn’t get around to publishing it.

RS4/RS6
HT-Motorsports crazy ongoing RS6 engine swap into a B7 Audi RS4 has seen its share of fabricated parts. For example, the turbo manifolds received 20 hours of TIG welding, while the new intake manifolds hold 16 injectors, and a CAD-designed dry sump seals the block.
After installing a 10-gallon fuel cell in the trunk, the team must plan the route for the fuel system components. They can then feed the heads that are currently undergoing final tweaks at the machine shop and should be ready for installation along with the engine later this month.
Pushing on, the frame horns, core supports and turbo shields are now stainless steel, and are supporting a test block to check clearance. This paid off following the arrival of one of the two Borg Warner turbos, which allowed the crew to start fabricating the exhaust.
The entire team is working to dial-in the project before the Northeastern winter sets in, and are aiming to have the engine dynoed before theres snow on the ground.
