If anyone is in the Philly, DE, NJ tristate area and has a car with modified turbo's I would love to meet up and get a ride so I can start to "feel" what my options are.

Regarding the 16 vs. 24 issue...The ZC K16/24 is a great package and I love mine. It is very enjoyable and offers little to no lag. However, it is coming off next week for a Protomotive 650, K24/18G set-up. Why? Well, there is nowhere left to go with the 16/24 turbos and I want more pull. They spool very quickly and pull hard to a certain point. Then they seem to run out of steam. They still pull very well, but the 16/24's stop building more power in the way they do down low. Now that I am used to it, I find myself sitting there wanting the car to pull harder in the higher RPM's and it's just not there and there is not much more these turbos can do. Like Kevin (KPG), I feel I have maxed out this package and as great as it is - want more. My test drive demonstrated that the Protomotive 24/18G's will provide the additional power and the stronger pull to redline that I am seeking.
Regarding the lack of K24/18G data...I hope to have some 1/4 mile ET and trap figures to compare later this spring. I have driven both and there is no doubt that the Protomotive has more lag, however, I was left feeling it was a more thrilling power delivery. I was not sitting there in the high RPM's thinking "I wish this car would pull harder"...it was more like "man this thing is fast!" Time will tell - I have some pretty good 16/24 figures to eclipse, but I think I am on the right track.
In the end, it depends on what you are looking for - I am seeking a faster 1/4 mile car, both ET and trap. If this was not a concern, I would probably have stayed with the 16/24's, but I've been bitten by the 1/4 mile bug...

If you are going to go for 700 hp now or later it changes the whole discussion. I know my setup posted the fastest 16/24 (as far as I know)trap of 128.2mph with a 3800 lb running weight. It also broke into the high 7's in the 60-130 as well. Unfortunately, there are no hard numbers for the 18/24G setup at this 600 power level. No one has posted any 60-130 numbers and the only 1/4 mile time that I know of was a 124-125 and 12.00 with a tippy. If no lag is the defining criteria, then a 18/24 isnt the solution. Many have claimed they are superior up top, but from the dyno sheets posted I would have to disagree. I have done several comparison spreadsheets that are floating around here that illustrate the differences in 100rpm increments with the stg2 ZC and the 18G/24... Keep in mind comparing dyno sheets are only a guide and hardly definitive, heck even trap speeds arent the same with different altitudes, temps, etc...I think there is enough info on this site to make an informed decision. I would just split the case though and drop in a GT3RS crank and be done with it, but hey, thats just me

one thing I noticed with my old 16/24's is they were much more easier to heat soak. once heat soaked power drops off very quickly and take a longer time to recover.
now with my 24/26 I have not expereinced drastic power drop off even if I expereince some heat soak it doesn't seem to rob that much power.

it's was soo drastic that even my butt dyno could feel the huge diff. just no boost, or what ever there was it was just not the same. this is in warm-moderate ambient temps. if you are just cruising around the blvd you should have no problems.

My experience with these is that I have never seen anyone run 10s on a simple turbo with a 5 bar FPR... Bobby in Tulsa claims he did it... after talking with him I believe him... he told me what he did. I do not recommend anyone doing that... LOL
