Congrats on the GREAT numbers, now get the GT700 package installed!
Why aren't you going with 355's (like my Viper's and what I just ordered for my Supra)? Are you running a 12" or 13" rear wheel?

Am I off here or did I bring up a valid point?
in a 1/4 the gt2 is faster.... where is the lag???

This is a great point.
I guess it is all relative. While we tend to say that turbos x and y are laggy, it is only in relative terms. If you take a stock K16 996TT, you will see that up to 2700-2800RPMs, the K16s will outperform (torque and HP) a K24 based GT2/X50, and then there is a huge jump in torque from the K24s right after 2800RPMs.. While they are laggy, they are not "that" laggy and under driving conditions, you would hardly feel anyhting as you know.
In the case of this mild setup, no mods were done whatsoever to fueling, breathing, MAF, or exhaust, and the absence these mods does not help reducing lag of course.
Now look at performance...if a similar program managed a 10.7@130mph or so, that means that it did a 60-130 in about 7.5-8.0 seconds, compare that to a stage 4 and the 60-130mph timing on the AX22 (9seconds +) of the stage 4, and you will see how little this K24 lag impacts performance, 1.0-1.5 seconds faster is easily equivalent to over 100hp difference, then there must have been some weight reduction mods.
These exact same turbos are what Divexxtreme has, and he ran what we all know, the difference is that he had air inflow improved and more fuel, that 's all, so no, lag does not hurt performance.
I certainly don't complain about any lag with my huge turbos.

3.6L TT's really aren't all that laggy... even mine isn't!

I also had a 86 911 Turbo with headers, more fuel and 1.0 bar boost spring,
larger turbo, etc. Now that was Laggy. Hold on and pray if you are
on any kind of bend when boost came on. Throw in a little "spring sand"
on the roads and an off camber, decreasing radius turn and now you are
close to seeing God, right AFTER you felt lag!! LOL

Martin, stock k24s are laggy compared to k16. but if u have the air flow then its no problem. custom k24s I believe are the way. And most other tuners dont use k24s cuase they dont have them. so they take ur k16 as base and port them out to bigger specs... or even put on big garrett housings... just like the k24 if not bigger.
I have a gt35r on my 2 liter evo and I dont mind the lag.... I drive around town on vaccum.... the moment someone pulls up the monster wakes up... I love.
