K26 and K27 Compressor size ?
Hello
Who knows the exact compressor wheel size for K26 and K27 turbo's:
- Impeller diameter
- expeller diameter
- Shaft diameter at bearing
- Intake tract
Thank's in advance

In fact both side have a role in spool up:
- Big compressor = more weight and more aerodynamic drag = more lag
- Big turbine = more weight and less efficiency at lower speed = more lag...
And the opposite with smaller components
Big compressor / Small Turbine = less lag but more thermodynamics effort on turbine
ETC.

Here are the spec of a k26/6 turbo i bought as a core for a hybrid i plan on doing.
-Compressor housing: I.D. of inlet = 1 13/16”
O.D. of inlet =2”
O.D. of outlet = 2”
-Compressor wheel: Inducer dim: 1 ¾” (44 mm)
Major dim: 2 9/16” ( 64mm)
-Turbine housing #6: Inlet I.D.= 1 15/16”
Outlet = 1 7/8”
-Turbine wheel #6 : Inducer dim: 1 7/8” (48mm)
major dim: 2 7/16” (54mm)
I have been reading up on turbo’s and i think a #6cm2 turbine = a .36 A/R And a #8cm2 (turbo s ) turbine = .48 A/R
I have been trying to compare a k26 to Turbonetics Turbo's To see what Turbonetics turbo could replace a k26/6.And this is what i have come up with.
I think that a Turbonetics T3 55 trim compressor and a standard turbine with .36 A/R. is the closest turbo to a k26/6 i could find.
What do you guys think?
I would also like to find the specs for a k27 compressor housing and wheel… Please someone must have it out their...

Thank you for the answers
As for the K27 there is apparently a lot of sizes and models.
There is one model not very well known:
- K28 3770 MXA seems to be used on Audi RS 2
The K24 seems to replace the K26 as they are of the same size but K24 is more modern design inside.
The only thing for sure is that KKK turbo's are not so antiques and a lot of improvements were/are made on the internals but not refleted by a new type number.
Ex: GT1 cars used 2 K27 with Ceramic components inside....
Best regards
