And Larry, I forgot I needed Mr. Cable's input too. Done, noted. Thank you!

Remember that part in Bohemian Rhapsody when it goes 'No!No!No!No!No!No!No!'?

That should be playing in your head right now. It's competing in mine with the thought of trading out my CS and $50k for a GT4... I just wish one of the voices would stop. Doesn't matter which.

For perspective, I made my decision this way; I don't buy Porsches all that frequently, so I like to get the "top of the line" of whatever model I'm interested in -- Boxster S Special Edition, Turbo X50, etc. So for me, the total package of the GTS is what makes it the "top of the line" Carrera for now. But that includes the widebody, the CLs, the interior goodies, the X51, the aero, etc. All of that was worth the extra $15,000 premium to me. But the power alone? Not a chance. My Turbo's X50 package was $18,000, and that too was ridiculous, but at least that gave you an additional 35hp and 52 ft-lbs of torque, which you can VERY MUCH feel compared to a standard Turbo. The X51's 30hp and zero extra torque for $16,000 doesn't make as much sense to me as a standalone adder.

Right now no voices or music are playing in my head, but this little red guy is on my left shoulder saying do it, and this pretty angel on my right (looks like my wife) is saying don't do it! But I can relate. The GT4 is an awesome car. YOLO probably applies more in your case than mine as I really like the car I have. Thanks Arc.

Even if you do the X-51 your car still does not match you RL name!

RobC4sX51

Not a concern but why, because of Rob or no cab in my RL name? Nice car btw. Love Guards Red, had two of them. And those ST wheels are my favorite

Geez if the X51 could be had AND installed for like $8-9K it would be tempting!!

I guess the "break point" is this issue? My Indy mechanic would charge less than half @$3150 (35 hours X $90/hr) but he and I agree that Porsche probably would not warrant it if he did it. The details in the installation guide for it are really amazing and full of interesting things. I know guys talk about break in considerations and I'm not sure Porsche publishes anything but they do for this X51 retro install. First 500 miles the engine speed can not exceed 5k rpm. Also, the plugs get changed and are different than the base S engine. I have obviously invested time into this consideration but that is it so far. Leaning towards all the answers above: not one RLer said "do it"!

I have the PowerKit in my 991 and I love it. Mine was a factory install and I bought the car used. There is no way that I would spend the money to retrofit a vehicle that did not have it.

I would just put the funds aside and enjoy your current car as it was born.

RobC4sX51

I like how you put that, thanks.

RobC4sX51

Cost or a different reason? Just curious. Thanks.

Zucc

Definitely cost. I love having it but adding it after the fact is just not cost effective.

RobC4sX51

Seems like the "implied" reason for about 90% of those above too, which I understand but I also know that a few lucky souls "ticked the X51 box" when they ordered a new 991! I could never afford to do that but to get the car preowned for 65% of the msrp and 13k miles, this add-on doesn't seem so crazy any more! Bad logic? Maybe!

Rob -- do you have a copy of this manual??

RobC4sX51

Yes, in PDF form. You want a copy?
