2.5 Mounted in the proper direction in the original quattro. 07k UrQuattro

Some folks have seen this car around the net. I have owned it since 2004 when it had a MC2 10v engine on CIS. Around 2008 for the UrQ-25 event I removed CIS and the standard turbo garb in favor of 034 IIc with custom tube header, 2871r, 3" down pipe, and lots more.

Now another 4 years into that evolution it was clearly time for something new. You can't swing a dead cat without hitting a Type 85 running a 3B or AAN 20v these days. After some deep discussion and serious 07k envy, my buddy Hank Iroz and I were determined to take on a project that nobody else seemed to be up for.

The goal: longitudinally mounted 07k paired with an 01e trans, Torsen rear. A true quattro.

The starting point:



Underhod:



Header mockup on the stand, turbo of choice is going to be a 35r squeezing E85.



Here is the assembly set in place for some more measuring and accessory mockup. One major hurdle was the fact that the 07k had no real provisions on the left side for engine mounts. Iroz Motorsport came up with a solution, replace the original oil cooler with an integrated oil junction / engine mount.



Even if we add as much weight as Hank (98lb) ;o} We are still this much lighter than the previous setup. Significant weight reduction is apparent by the fender gap at the front.



Here is how much room we have on top at the upper core support, I don't need to sing the praises of the 07k on this site, but in my traditional I5 world this is big stuff. It comes at the price of some unique challenges though.



Huge gains made down low, room for a nice thick core for a low mount intercooler. One goal of mine was to keep the original core support intact, hacking out the core support for a front mount was unacceptable.



Tucked in nicely is a dual pass radiator, and we aren't giving up any accessibility and still room for fans. This is another benefit of the shorter 07k, the quirky side mounted radiators that have always accompanied the Audi Type 85's can be replaced with a more traditional and efficient configuration.



This is a single-core, but promises way better surface area over the stock radiator



With consideration to all the fitment and measurements, they are worst-case scenario - the engine can and will move towards the rear by 3/4 of an inch once we get the proper transmission mounts fitted. The assembly is all sitting on standard RS2 transmission mounts.



Still have lots of supporting mods and parts required, but this is looking pretty promising as it comes together.

This gets us up to date with our progress, which started the end of October.
