600hp from an NA 4.0 would be epic. Here is the write up on the Bosch system in the M4GTS which presumably would be what would be fitted to the GT3 if the article is correct.

My question is what do you do when it is below freezing? It’s 7 degrees out right now where I am. What do 2RS owners do? Is there a drain or something or do you just not park or drive in freezing temps? The only similar systems I am aware of run 50/50 methanol/water so it does not freeze. In fact my friend who has such a system on his Cummins would just run winter washer fluid in it.

Right - particularly with a 4.0 Flat-6. Cylinders are too big to spin that much mass that fast. If some company wanted to surpass 150 hp per liter with an NA 6-cylinder motor, it would be far easier with 2.0L (only 300hp). For 600hp, 4.0L V-12 would be the way to go (doesn’t fit in back of 911).
If you were Porsche and wanted a 600hp GT3, you would choose turbocharging or electric motor additions.

as the current 992 transmission has room for hybrid components.. and GT3 is unabashedly an NA offering, i'll shoot a premature spray across the bow, FXZ style.. and say it's "CONFIRMED" that GT3 will NOT go turbo. It's quite logical in fact to see that 992.2 could go hybrid-NA.. just with a small battery to help with torquefill and possible 50 or so extra HP, while still keeping to a glorious 9000rpm + redline. If you've ever driven a 918 spyder, you will understand the incredible driving experience of this drivetrain.. you get ALL the NA sound, with ALL the NA throttle response, but with a massive dollop of low and midrange torque, with the NA engine fully focused on taking care of the top-end. I've had the pleasure of hustling both 918 and 918 Weissach's around a few tracks, and aside from the considerable weight of the car felt under certain braking situations.. it was simply otherworldly. Porsche would not have put this much development money into hybrid if this weren't the plan for trickle-down into other cars. 992.2 will be NA-hybrid, if you connect the dots, you will know this to be true.
in the meantime, here is an excellent video from the always enjoyable MRJWW on the pleasure of driving the 918... trust me, you WANT this to happen.. it's the ultimate drivetrain combo.

I doubt the 992.1 GT3 will be anything but NA.

Why Porsche wants to invest so much to make a major improvement on their next gen GT3/RS? They simply need to tweak a little bit, and announce this is the official last NA, and they can sell triple the volume of 991. We will be flighting in the line to get one!

^ lift, depends
I don't need it. but if you have steep driveway, you need it
does it affect value? yes. I will not buy any with front lift. that's just me
many other will not buy a car without.

We all forget that GT3 RS must clearly heading towards the GTLM RSR homologation rules

For reference, the brand new 911 GT3R factory race car has a very sophisticated intake with 6 individual throttle bodies and race exhaust with a 9,400 rpm redline (redline info from Guest89), comes with zero warranty, and is rated at 550hp without a restrictor (Click on "The Drive" or look at attachment):

Or you could just get to a 600hp 4.0L with a revised intake, exhaust, and tune like Dundon is about to do. I think electrification on the 992.1 GT3/RS cars is going to be pretty un Porsche-like and a bit premature. I could see it on a 992.1 Turbo S E Hybrid but not on the GT3 cars until maybe 992.2. However, I do agree that the future GT3 cars may stay NA with a small hybrid system of some sort. That'll make for an incredible package but I hope it's not too harsh on tires. (They'll probably address this with Michelin anyways) Also, I'd assume a hybrid system could help with brake pad life (by way of brake re-gen) and maybe even allow for a smaller/lighter brake system overall? Maybe this along with a lightweight hybrid system could help minimize the weight burden of the additional system and lessen the tire degradation concerns. We shall see.

The factory builds a 4.0 liter flat six that develops over 600 bhp with no sonic restrictor fitted; it's in the 911 RSR, which costs €991,000 plus spares, plus delivery (if Porsche will even sell you one).
A crate engine for the car is in the ~$250,000 range, per more than one person I know who works for the factory's operational partners (Core and Manthey).
Please reach out to Pascal Zurlinden (link below) right away and let him know that a small, independent shop in Washington state can deliver 600+ bhp in a street car while those second-rate losers who work for Porsche Motorsport can barely get that done with a blank check! It's too late for the Daytona 24, which is this weekend, but maybe they can get some help - or at least save a little money - before Sebring.
