It has been a while since I wrote a tech thread for vortex so I may be a bit rusty.
COMMENTS:
I grew up on the 026/037 motors i.e. generic external water pump 8V's & 16V's which most of the vwvortex elders have great experience with,however,Over the past 3-4 years I have grown very fond of the 06A/06B and now 06F blocks for very simple reasons:
* Removal of an intermediate shaft
* Relocation of oil pump from the rear of the motor to the front of the motor and driven off of a chain rather than a belt
* More ribbing in the crankcase than any pre-1998 VW motor
* Implementation of 3 extra oil returns for the cylinder head casted into the rear block.
* M14 coolant feed port at the back of the block for turbocharger
* Water pump is now timing belt driven vs v-belt/serpentine belt.
And a few others which we will not get into today. Here at INA Engineering it has been a crazy roller coaster with trying to keep up with the expansion of the company AND finding the time to do what I really enjoy which is build VAG engines of all magnitudes. I managed to get my hands on one of the new CCTC motors (for a hefty price :( ) just to document the differences. I will say this for the record that I still cannot find myself seeking the advantages of the 06H block which by design makes me wonder what VAG was thinking. :sly:
If VAG really wanted to use balance shafts, chain driven connections between the camshaft and crankshaft and finally a camshaft girdle, all they had to do was subtract one cylinder from the Rabbit 2.5 Motor, add a cast aluminum oil filter housing and voila new CCTC motor ready to rock however this motor has SO MANY changes it is not even funny.VAG has always been known for their "Lego like" antics in motor engineering. I.e. taking a part that worked from a previous motor and modifying it to work on a current motor.
What many people do not know is that you can essentially take a VW cylinder head from 1977 and place it on a 2007 06F block, however with the 06H engine, we enter a new breed of VAG motors.
Jeff Clark first brought the new motor to our attention back in early 2008 a full year ago (http://forums.vwvortex.com/zerothread?id=3749316&page=1) but I now witnessed the differences first hand.

Arin Anhill (Arin@APR) was kind enough to host the images of the new motor up from the tech article so the artsy savvy of you can enjoy these:

Major differences include:
* Balance shafts casted into the block
* 2 piece baffled oil pan similar to Oettinger of the late 80's
* No more valve cover - camshaft girdle is more pronounced and baffled system is integrated into the cover.
* Water pump relocated to the centre of the motor and driven off a cogged belt on 1 of the balance shafts vs a timing chain.
* Dip stick tube relocated to rear of the motor
* Timing chain vs timing belt
* Oil filter housing is now back to cast aluminum vs plastic but is now integrated in a bracket with the alternator & AC compressor
* Fuel pump is now driven off the exhaust camshaft via 4 loebs vs 1 on the 06F system.
* Smaller FSI injectors
Thankfully there is always a connection between an outgoing motor and a current motor. In the case of the CCTC motor that connection is the manifolds. Both the intake and the turbo manifold from the 06F will work on the 06H as the flanges are the same so those of you with APR turbo kits can easily move onto the next motor : cool:
For simplicity purposes, in the text below,
AEB = 1.8T cylinder head
BPY = 2.0FSI cylinder head
CCTC = 2.0 TFSI cylinder head
