my (very last minute) #supercarfastsleeper - Audi RS2 Avant

(all pre conversion prices are in AUD - my native currency)
The Audi RS2 Avant is a wagon, but not just any wagon, it’s a 2.2L turbo 5 cylinder, AWD wagon built in collab with Porsche. Assorted Porsche bits include a brake, wheel and tire package taken from the 968, door mirrors and the 6 speed manual gearbox. From standard it produces 317hp, goes 0-60 in 4.8s, went 163mph at the top end and does the quarter mile in 13.7s. As fast as this mad wagon is, unfortunately however, it’s not McLaren MP4-12C fast. The British brute produces 591hp from it’s 3.8L twin turbo V8, goes 0-60 in 2.9s, 205mph at the top end and the quarter mile in 10.7s. The MP4 is in a completely different league to the Audi, but it’s to be expected. The McLaren is a brand new €170,000 supercar. The Audi is 24 years old, it’s a wagon, and costs less than a third of the McL (this guy ( https://www.tradeuniquecars.com.au/detail/audi-rs2-569536 ) wants ~€45,000), but what if the extra €125,000 was spent making the Audi even faster….

Audi RS 2 Avant - £39,995 (€45,292)

weight saving and interior
The Audi will need some lightening to make it quicker than the McL, so losing all the seats (excluding the front seats), losing the sound system, climate controls and other useless interior nic-nacs can go (all you need is a seat, a steering wheel, a gearstick and 3 pedals after all). and to keep the ‘sleeper’ look to it, the windows might need a tint to make sure no-one can see inside the car and see all the missing bits…
window tint - $600 (€378)

wheels and tires
The wheels can be one of the biggest giveaways on a sleeper car, so keeping as close to standard is best. Standard wheels are sized at 255/35/20 all around, so that leaves many options available to us. Fortunately for me, Pirelli makes the P ZERO, which comes in the exact size I need. Problem is… they’re a bit expensive… at $372 per tire they’re not cheap, but they’re definitely going to come in handy

Pirelli P Zero 255/25ZR20 x4 - $1488 (€938)

running gear
Let’s face it, going McL fast on 20+ year old running gear is not something I particularly want to do, so that’s where K-Sport comes in. Part Number KS-AU-006 is a set of adjustable coilovers I would put my life in the hands of. For $1299 they’re not cheap, but I want to live after driving this Audi at McL speed. Some brakes would also be a nice thing to look at since I don’t think the standard brakes are quite going to cut it, so a set of brembo 6 piston brakes (front) and 4 piston brakes (rear). should cut the mustard.

K-Sport AU 006 - $1299 (€819)
Brembo 6 piston brakes x2 - $4411 (€2781)
Brembo 4 piston brakes x4 - $2395 (€1510)

Parts total: €5110

Engine
Now we get serious. 317hp is all well and good, but we have to take down a car making almost twice that, so we’re really going to have to get serious here. The stock Kuhne Kopp and Kausch turbo just isn’t quite going to do the job, so I’m going to “borrow” a different turbine: the same one that you might find strapped to a modern day Indycar for that matter… The Borg Warner EFR-7163. This insane turbine packs quite a punch, capable of 1.9 Bar of boost (28psi), it can produce in excess of 600hp. This much power is going to destroy the stock internals of the little 2.2L 5 pot, so some new parts should save the day. JE Pistons forged pistons, PEC Automotive forged conrods, a Nilgroup stroker billet crankshaft, a DPR Racing cylinder head, cams, a V8 Audi R8 oil cooler, a Misimoto radiator and a VS Motor dry sump ‘should’ be enough for about 880hp: more than enough to make the McL start to sweat.

Borg Warner EFR-7163 - $2,906 (€1832)
JE forged pistons - $749 (€472)
PEC conrods - $687 (€433)
Nilgroup stroker billet crankshaft - $1500 (€945)
DPR Racing cylinder head - $1450 (€914)
Cams x2 - $29 (€18)
R8 Oil Cooler - $850 (€535)
Mishimoto racing radiator - $709 (€447)
VS Motor dry sump - $3350 (€2238)

Parts total: €7834**

Drivetrain
The standard clutch might not survive all the added fury, so a new clutch is in order, courtesy of DC Performance, this’ll happen, and Wavetrac Differentials will help transfer the fury to the wheels

DC Performance clutch - $470 (€296)
Wavetrac differential - $1395 (€880)
