The Stage 2 turbochargers provide alot of power under the curve. If you are building a race car, or a drag car and live above 140MPH making the switch to K24's might become a choice. For myself, If I need to have an engine that required the upper end power I'd dump the K16, & K24's and use the K26 platform.. Many Euro Tuners have done this. Lately I have seen the trend of K26/27's..

I almost can't shift fast enough now, and end up shifting at 6200 or 6300 rpm anyway.....so a K24 would be wasted with me behind the wheel.

More power down low and less lag would be my preference

Very well put. The additional lag is NOT and issue!

FVD installed a larger K26 compressor into the K24 frame. Very nice combo indeed.

Thats perfect then. As long as you are clear what your goals are then you can choose what you are willing to sacrafice. You have chosen well. Its those who complain about power drop off on the smaller turbos that need to consider the larger K24 based turbos.

To some people lag is an ISSUE.. Many people have read these threads in the past that minimalize the impact of buying K24 with lag not being an issue. When they get the turbo's bolted on there car, they can't wait to get them off.. The question is, do you want the power now or do you want it later.. And later is really at 6200-6600 when compared to the larger Stage K16 based hybrids.. One has to also realize that in my manufacturing process I am enlarging the A/R and freeing up the K16 turbine side.

Lag is only an issue if the person(s) are foolish enough to "bolt" them up to a stock exhaust system and software. With a well modified exhaust system and tuning the "lag" is less than the car was in stock form.

The cross over point is closer to 5,200-5,500 RPMs not 6,200-6,600 RPMs

It really depends on what more important. Max power vs max response.

How does the Stage 2 compressor compare to a K26?

Not even close in size. The K26 compressor is much larger. They make several versions of the K26 compressor wheel so I can't give you an exact comparision. It does sound like FVD did their homework and nailed the package though.

What's the difference between the GT1 and the Stage 2?

The size of the compressor wheel on the stage 2 is larger. If you like the K16's and are willing to accept the limits on the top end I would suggest the stage3's from Kevin. I think that turbo has the best balance of the hybrid K16's.

We are going to have some fun with this post. I have dug into my stash of compressor wheels, and have picked out a few good show and tell items.

Turbochargers manufactures have different frame sizes that they use to instill basic guidelines for installation/applications. Many a situation has a timespan of 10-15 years go by with the introduction of newer models and frames. However, you can get caught in the numbering and assume that if it has a larger number it is a larger turbocharger. Well that's not exactly the case.. I have posted three compressor wheel from A,B & C.. One compressor wheel is a prototype K16 or K24 with no basic OEM numbering, one is a K26 that is used in K24/K26 in many Euro Tuner (Porsche 993TT and 996TT applications) many of you folks are talking about the same wheel, the next is a K27 compressor wheel. Tell me which ones you think they are....

To state the obvious A is K27 B is K16 C is K24 . Now tell me how and why I am wrong.

Red9, no not correct. I did retake the picture with the X50 or GT2 compressor wheel (far right) as a reference..
