Save it for the Spyder. I'll be your guinea pig.

 

 

I have yet to see anyone blow up one of the newer generation 6-spd manual transmissions from too much power. Obviously there have been the issues specific to the GT4, etc.. but for the most part that trans is rather beefy as it began life in a FWD diesel engine based car in Europe. Neither the PDK nor the manual have an issue with the 4.2L. As far as i can tell, you're okay!

 

I would want one with close ratios 6-speed manual with top speed between 160 and 180 mph.

I think it’s unlikely we will see one from Porsche. Hoping for a 718 R as a internal combustion engine Cayman send off.

If Porsche doesn’t make one, I would want 2 GT4RS. One PDK and one converted to manual (assuming I can get 2 )

 

Are you saying you can do it? Also, how much? The main reason I'm not trying to get a GT4 RS is no manual. I'm thinking about trading my GT4 for a GT3 for more power, shorter gearing, and staying with a manual. Though, I love my GT4 and looking to get a tune and muffler, already have headers and mid pipe.

BTW BGB, I'm in Florida now! Only a few hours drive away, I need to stop by one weekend.

 

AP, said the current gearbox cant handle the 9000RPM.

 

with a six speed manual, GT3 engine, and no roof… will be the last car I ever own

 

Looking for mid-engine? Otherwise, Speedster fit the criteria, yes?

 

I didn’t think the 992 GT3 had shorter gearing? I recall it had tall gearings for sound regulations.

 

Porsche also said at one time the GT3 engine wouldn't fit in the Croc.

That is true, the 991.2 GT3 engine did not fit in the GT4. But we’re now talking about the 992 GT3 engine, which it does.

 

I’d definitely be interested if it came with a manual! The gossip about a Spyder RS is also intriguing, but people are hinting towards a Bergspyder like concept which is not very appealing.

 

992 GT manual has lower gearing than 991.2 manual to offset the larger diameter rear tires (21”). Close to 6% difference

 

YES! Thanks for the vote of confidence! People have already started calling and asking and sniffing around. I can see coupons being printed soon!

We knew it would fit BUT the electronics have always been the issue. If i can't get it to work without the dash lit up like a Xmas tree, i feel like "what's the point."

BOOM! I'm spray painting a parking stall for you now in the driveway!

Whoa whoa whoa...you went full Florida dood? Yes, you need to visit. I guess that's the good thing about the mass movement to Florida...more P cars are starting to show up on the road which is rare for this part of the world.

Obviously they would know and everything i say is simply conjecture BUT....we know a few things. 1.) the single biggest push for the RS road car in addition to the buyer demand is to create a homologated race car for our GT4 class. Porsche will not EVER make a track only car with a manual so we know it will be PDK. So for rules reasons we need a Cayman with PDK and a GT3 motor. 2.) we know that the RS usually gets the PDK because it's the flagship track car and they don't want humans bobbling shifts and zinging motors. It's as much about lap time as it is about removing the driver from being able to blow the thing up.

I have a hard time believing that it can't handle the power BUT the RPM could be something as that gearbox is not meant to rev that high. In addition, the gear wheel fluid and the transmission fluid is cooled by the pump driven off the gearbox and it might not be able to keep up with cooling demans if it's turning 9K RPM. So the gearbox might be up to it but the cooler may not? Who knows. I was one of the biggest supporters of the manual box that went into the GT4 and then the whole 3rd gear thing went down so i should probably shut up. I could be wrong...someone just dug up a thread from 2013 quoting me that this car would never be built. i would be amazed though if they A.) ever offered it with a manual B.) made a Spyder variant.

 

Hey John...now that Porsche has mated the GT3 engine to the 718 electronics/chassis how about a GT3 engine swap into a GT4? Would it be better than a 4.3 liter upgrade to the 9A2 engine?
