Porsche Cayman GT4 Upgraded With GT3 RS Flat-Six Engine
Track-focused Cayman now comes with almost 500 horsepower. For the past several months, we've seen countless spy shots of the rumored Porsche 718 GT4 testing. Unlike the original GT4, which was powered by a 3.8-liter flat-six from a 911 Carrera S, this new car is expected to use a detuned 4.0-liter flat-six from the current GT3 that produces 500 horsepower. If you just can't wait for Porsche to reveal the new 718 GT4, a tuner called DeMan Motorsports has you covered with a flat-six engine upgrade. The stock engine delivers 385 hp, though Deman says its new upgrade will produce 488 hp and 360 lb-ft of torque at the wheels. Factoring in a 15% drivetrain loss, this monster now produces 561 hp and 414 lb-ft at the crank - an increase of 176 hp and 105 lb-ft of torque over stock. This 4.25-liter GT4 is even more powerful than the current 911 GT3 RS. DeMan has even posted a dyno video showing the car hitting its increased 8,000 rpm redline. According to Road & Track, optional titanium internals can further increase the redline to an eye-watering 8,500 rpm. So what's the cost for this incredible upgrade? 28,500, plus the cost of a Cobb access port. DeMan says most of the customers interested in this sort of power increase have already performed other upgrades to their car, allowing the base price to remain fairly reasonable. Even when Porsche does reveal the 718 GT4, we know it won't be as impressive as this.
I have not driven the Corvette or the Camaro in over a month but I cannot go more than a week without driving a GTS. I have tracked both Chevy鈥檚 numerous times but find the GTS to be the better car. I will probably sell the Corvette and Camaro sometime in the future. I had the advantage of not growing up with Porsche flat 6 sound so the flat 4 sound did not turn me off. I found the instant torque of the turbo four far more likable than the NA flat six. I did drive a 2016 GTS before I bought the 2018 GTS and had no regret buying the 718. The Cayman GTS has the same 0-60 time as my ZL1 and Z51. Again, I have no regrets. I do not think you will either. Let me just say that I love my Cayman GTS ! I have a 2012 Camaro ZL1 and a 2015 Z51 in the garage next to the GTS. I have not driven the Corvette or the Camaro in over a month but I cannot go more than a week without driving a GTS.

I just sold my E92 M3, because it was sitting in the garage since I bought my 718 S, the exhaust sound on that car was sublime, especially when running to the 8400RPM red line. I also love the sound of the 2.5 F4, but I love the power delivery even more. I will miss the high revving V8, but as I said, the car was mostly gathering dust in the garage. I am in similar place as you; but been trying to figure out best time to buy. Was btw a 781 GTS and 718 GTS (Prev had a 2015 Cayman S). Seem to be a decent number of 718 GTS Sitting at dealers still not sold have been hoping with the 718 T coming out the 2018 will fall in price some.

But still looking if I can retrofit an autodimming mirrors. The other options I can live without.
