Quick question (while we're on the topic).
When you make a K26 into a K27, I assume they open up the cold side for a bigger wheel. Is it possible to source my own wheel? I have equipment that can grind to tolerances within millionths of an inch. Just makes me think I could do some research and build it myself.....

What I meant is that it's not easy to find any K27/6 for sale here in Sweden and since I have a K26/8 the "upgrade" to a K27/6 is not cheap.
How much power is the K26/8 original turbo good for?
A Vitesse kit would be great, the reasons for not going with that as my first choice is the $ to SEK ratio and the Swedish 25% VAT which makes these kits a bit expensive
I'm not in a rush, these plans are for late autumn modifiactions.

Not discounting the turbo you're selling (nor am I familiar with them...), but in my opinion, for a street driven daily driver car, anything using the KKK ~8 hot side is too laggy (just like the K26/8 is)
The additional power ain't worth the lag. If people are willing to deal with the lag of a ~8 turbine, they might as well go to something bigger and get it over with...
The beauty of the K27/6 is the balance of price & quick boost. It just happens to support the 325RWHP range.
Why don't you do a custom compressor capable of supporting 330RWHP on a KKK~6 turbine? That would be the setup.

Another issue with the K26 based turbos is availability. New K26 turbos are expensive, and at times very difficult to find.
The Stealth turbos were designed for the track guys that want a "bit" more power, yet want to keep the stock look. The goal was 300rwhp and similar torque.. Track guys love them! They just want the extra punch to even out the playing field
I think the market needs a entry level turbo, a good performer for street duty and a moderate price tag. Bundled with the engine management to provide a great bang for the buck for the budget minded customer. That's what I'm working on.

The problem with the K27/6 (or 8) is that they are hard to find and sending in av K26/8 to get it to a K27/8 is not that much cheaper than getting the SFR turbo.
One of the problems is to actually get info from someone using the K27/6 or 8
or the SFR hybrids so I haven't got any charts to show.

I am still troubleshooting why the tires became less sticky with the new turbo though...I need to get it to the dyno...
Maybe the end of next week.

What kind of turbo is your new turbo? How much for your 27/6?

Personally, I'm not a huge fan of the K27/6 or the K27/8. They are robust turbos, inexpensive, but not my favorite. I agree with you the K27/8 is on the laggy side. The K27/6 spools up fast but is restrictive up top. There are other options (yes more expensive), they spool up just as fast (if not faster than the k27/6) yet provide much more performance. It boils down to budget, requirements and personal preference.
Another issue with the K26 based turbos is availability. New K26 turbos are expensive, and at times very difficult to find.

Here's an old one of my K27/6 with a Bursch 2.5" test pipe, Huntley MAF, ARC2 fuel controller, chips, 52lbs Rochester injectors, and adjustable fuel pressure regulator.
PS> Ahhh the old days of tuning....
The ignition system was weak... which is why the dyno looked the way it did on that day,.

Dont know as i run a little bit more than 15psi but my maxboost is at 3350rpm fourth gear. The turbo seems to have an insane spoolup had problems with the wastegate in the begining was hitting 1,8 bar before i even knew it !!! Before anyone comment it yes i know i was running way rich and yes my instrument cluster weren't working
