I just wanted to put together some info on VW/Audi's new 2.0 liter 16v turbo direct injection motor.

first some tech specs.
running on Motronic MED 9.5 ECU
Quoted Valve sizes:
Intake = 27 mm with 6mm stem
Exhaust = 30 mm with 6mm stem
Bore is 82.5mm and stroke is 92.8mm
Variable Cam Timing upto 40 degrees
compression is 10.5:1 i think

How the are dealing with low timing belt life--

"The main components of the new technology are a newly developed sprocket (Litens SmartSprocketTM/CTC) and a high-performance timing belt (CONTI HSN-POWER®), which together act as a vibration damper system. This sprocket is slightly oval instead of round, giving rise to imbalanced forces with intentional force peaks in the timing drive. These forces are calculated such that they oppose the force peaks generated by the piston stroke, and opposing forces offset each other to a certain extent.

This reduction in vibrations is achieved only in conjunction with a timing belt with glass cord tension member and cover fabric, which functions as elastic component in the system. This technology reduces the forces that act on timing belts and engine components by 30 to 40 percent, so the width of the timing belt can reduced by 1/3. If the belt has the same width, its belt life is extended and it can be used for practically the entire lifetime of an engine without being replaced, even on high-load direct injection engines. Thanks to the oval sprocket / rubber timing belt technology, timing drives are quieter and require no maintenance, making it easier to fulfill the requirements of the Euro 4 and Euro 5 standards and reduce fuel consumption. And at the same time, sizes typical for chain drives are possible. The new technology will be used for the first time in TFSI engines from Audi and PDI engines from VW."



ICs on the A4s are dual sidemounst similar to a 225TT.. The IC in the sportback and MK5s will be a front mount radiator type similar to what some saabs and volvos use.

The N249 being built in should not cause a problem with proper chip tuning. Some of the limp mode current 1.8t owners put themselves into with boost controllers and such is actually the N249 telling the DV to open up. So as long as you are whithin the contraints of what the ECU is tuned for it should not pose a problem.

Theoretically you could always just unplug it and pipe in a regular DV or BOV, which is probably what will happen on most turbo upgrades.


the turbo is a new version of the ko3 with an integrated exhuast manifold with symetrical runners.


something else cool is you can run 87 octane becuase it injects the fuel and ignites it all at ones....no chance for knock.


and some pics....



MAF housing integrated into the engine cover...why? idunno









thats just SOME of the crazy stuff they're doing....
