Email me for a price quote, wes@titanmotorsports.com

I have 10 pairs of K24s in stock and can have the upgrade done in less than a week (I actually will have a set in stock as of tomorrow).

i got to agree with mark on this one... i had a 18 g with 5 bar , and neevr lost to a k24 car. and for that matter i havent seen any properly setup 18g loose to a k24.

the point that some one made that you NEED injectors and fuel pump with the 18gs or else theres no differance, is also false... the 5 bar works fine .i had one of the first 18 g setups from Todd, for along time. no issues , afrs were always in check.. now if you wanna do injectros as a precuationary measure then go right ahead.

sorry Tony but i would take Todd K's word over yours .

The bigger turbo (18G) is faster, hands down...... but not by so much. I trapped 125.XX with my K24 car. I took 2 runs at the track, who knows if I could have pushed it further with more trial and error. I guess what I am saying is that for someone with K24's to just swap out to 24/18G's is kind of pointless. You might as well go with injectors and a fuel pump at the same time, and I think the same goes with a K16 car. The move is to just do the whole upgrade.

ACTUALLY ur right on the money if you would go from K24s to K24/20gs.... trust me I know personally.... my best friend did the developent work on the 18Gs and 20gs on his few P cars some years ago.... he spent considerable amount of money putting different wheels into various housings.... and according to him ( mind you he has had 3 18g and 2 full 20G cars trapping high 130s) - he would go to 20gs with injectors, fuel pump, intake( very important), MAf ect...

As far as ur 125 mph trap.. its on the money.... however a 18G will trap 129 at 1.3 bars... and if you do injectors, pump , intake ICs.... the trapp may go up only 4 mph vs. 8 mph.... so why not just go to 20gs if it doesnt cost ANYTHING more then a 18G.. MORE HP for same $$$

I try not to use Dmaffo's example too much since he did everything right...
he ran 1.3 bars and not a 1/10th over... mixed 103 with 109 I think....
it was very cool day- I think in the upper 50s... (Canada)....
K24/18gs, Blown6 ICs, straight pipes, 5 bar, greddy, BMC filter, I think some Chineese made headers... LOl
He also took about 70 LBs out...

Mark,
so that is the upside of 20 G-- what is the downside compared to 18G. How far up the rev range does it move the performance curve?
What about a K24/3070/6 R types-- the same question as above??

I agree, it's funny everyone always compares record times and considers it the norm. Temperature, shift points, 60' weight all factor into this equation. A car in FL in the summer won't run 133mph on it's best pass. Turning a car up in the heat to try might lead to some interesting results LOL

You'll be fine, I've got 13 passes on mine (with less power) no issues and I've been launching her hard. We'll be developing and releasing some other must haves in the future as well to make track times much easier, stay tuned

Since I haven't run my car at the 1/4 mile yet, I can't comment, but I can compare 60-130 times. The fastest k24 car (996tt vs. 996tt) on the list is Pierre, and he ran a 7.84. If you compare that with my car, I'm almost .9 seconds faster at 6.96. That is quite a bit, and would venture a guess of 2-3 car lengths or more on the street. I don't have Pierre's file, so I don't know the distance it took him to get to 130, but I would imagine there is some difference.

On another note, I've seen videos of k24 cars vs. k16/24 cars, and the k16/24 car pulled slightly. When I compare the k16/24's I used to have to my current 18g's, I can tell you that there isn't much comparison...the 18g wins hands down.

Just my $0.02...
