that and the info with the gt3 production and RS production ending before 2018 is over leads me to believe there may not be a gt3 engine in there. I hope I'm wrong for sure..

but who knows right?
This is what I scratch my head about. Porsche doesn’t even want to make a 2019 GT3 because of presumably Euro emissions standards. So why a GT4 with the same engine? They can just run out more GT3s for 2019, which commands a larger profit margin for them.

If the delta between those two is ginormous (like with $70,000 luxury F250 pickups, for instance) then that's just icing on the cake (and is often used to offset the loss-leader Chevy Sparks at the low-end.)

I bet the actual cost delta to build a GT3 motor over a 9A1 is so little it's a rounding error on the total price of the car. The important thing, though, is to protect at all costs that $50,000 delta in sales price between the GT4 and the GT3 (think F250 King Ranch vs. Fiesta. )
Thank you great comparisons from yourself as well.

This is all beginning to feel like Mel Kiper coming out with yet another mock draft. We just want the pick to be made already.

Just being and driving on the Autobahn means nothing regardless of the few on here that seem to think that everybody knows what the public wants and therefore will accommodate.
I totally agree with you.....just wanted to get this file posted here.
If you read my post (and previous ones) I can't come to a conclusion of what engine it's without more info....guess we will have to wait for PAG to spill the beans or a brave soul to jump under one of these cars to take a pic!

Ok, to add to all of the rumors flying around, I just spoke with a dealer today and was told that they were told that there will be two unveilings at the Rennsport reunion in September. No indication or hints on which cars will be unveiled...

I wonder how Porsche would resolve the air intake/dry sump oil tank conflict if they go for the GT3 4.0. Seems like quite a costly thing to do for a limited series run.

my guess is that we see the existing 3.8L motor bumped up to 4.0L and with revised heads, cams and throttle body. improved Intake might be greedy. All simple stuff however.

Being a 4.0L, people will reference to it as GT3 motor, but realistically it will only be the block in common. No GT3 intake and no GT3 sump.

This is my guess.

I would tend to agree. I said back on Page 2174 that if you call it a GT3 motor, but then give it the oiling system, the con-rods, the redline, and the valvetrain of the 9A1 Carrera motor, and just enlarge it to 4.0, you've just created a marketing exercise. When 991.1 GT3 was 3.8 liters, if you removed the dry-sump oiling, the titanium con rods, and a few other racy bits that allowed the motor to make 475hp and rev to 9000rpm, well, you just had a Carrera motor. Which was already making 430 out of 3.8 liters back in 2013 when the X51 package came out. So why it takes 4.0 liters of "new" motor to make this supposed 420 hp for the GT4 I'm not really sure.

I kinda feel like we will see a spyder and 718r both with 4 pot turbo.

Im starting to think they will use two motors. The spy video in traffic of the Spyder is absolutely turbo. Photographer at the ring claims "it sounds more and more like a 4 cylinder" for the Spyder and the above gauge shows a 7k rpm rev limiter... Then GT naturally aspirated as some are claiming (I hope).
