Not sure if this has been mentioned anywhere but re: "room" in the engine:

What's next??? Should we take a show of hands on whether cars with flappy paddles and hydraulic lifter lumps should be relegated to invalid van service.
I think these 5 paddle shifitng hydraulic valved tubs should be the first ones pressed into "Meals on Wheels" service now that we have the .2GT3.

Wasn't the E46 M3 every 15k? Thought I remembered two 'major' services in the 35-40k I had mine. I know that they were checked but did not require adjustment, and that car did not have an easy life with me...

I had two e46 m3's back in the day. Interval was determined by ECU, so slightly varied. Roughly every 25-26k. I had two out of spec at 26k, and none out of spec at the 50k.

"The engine is an evolution of the 4.0-liter naturally aspirated flat-six used in the 911 GT3 RS, which itself is a stroked version of the last GT3's motor. This new motor is actually largely similar to those used in current 911 race cars, including the brand-new RSR."
For anyone one who is drinking some concentrated marketing Kool Aid saying that this new 991.2 4.0L motor in the GT3 has been derived from a race engine here you go. All these motors came from the 3.8L that we initially saw in the 991.1. They all found their way into their respective application. Albeit some of the components on the new street engine is shared with their racing counterparts.

Alright, let's get one thing straight about the Hydraulic lifters, the reason they were used in the 991.1 GT3 is that they were concerned that the rocker would float from the cam lobe at high RPM. They included a hydraulic dampener remedy this float/slap at high RPM. Unfortunately, as we now know that this is a design flaw that caused the cam lobe to score because there was too much force on the lobe as there was not enough oil running, thus introducing a new oiling system for the G engines. Now with the new gen II engines, they got rid of these hydraulic dampeners due to issues I just mentioned. Moving forward, they managed to scrap them and find the benefit of A) no more floating/slap at high RPM and B) no need for adjustment later in the engine life cycle. Let's see what the documentation says when we get our impatient grubby hands on them.

Seriously though.. I notice a lot of disdain from some .1 and RS owners.. Can't we just all get along!
