more info...
strange that the compressor is specified in inches, but it seems to jive with published info.
for example K04-2075
20 * 2.54 = 50.8mm wheel od
50.8mm * 75% = 38.1mm inducer id
<i>Further clarification on 3K turbochargers
Specification numbers below are different than part numbers.
Examples:
K04 2075 EACAA 4.82 1.8T upgrade has a 3K part number 5304 970 0015
K04 2075 EAC 4.82 1.8T 230hp version for 1.8T
NOTICE the inducer on these is a whopping 75%
=====================
K24 2672 GGC 6.12 the RS2 turbo.
K24 refers to the turbine housing or HOT side
Has NOTHING to do with the cold side.
2672 refers to the COMPRESSOR wheel
26 times 2.54 gives the exducer diameter in mm = 66mm
72 give the size of the inducer as 72 % of the exducer
GGC refers to the configuration
6.12 refers to the size of the turbine in the K24
housing
6.11 different turbine for RS2
6.13 even more different for RS2
==================
K26 2664 CA 6.95 the specifications for the 100/200/5000 turbo
K26 turbine housing
2664 26 x 2.54 = 66mm is the same as the RS2 but inducer is 64% of
that.
6.95 indicates a larger turbine wheel than the RS2
==========
Here is one I like for most higher end upgrades
K26 3072 GD 8.11
And on my new urS4:
K26 3472 HHB 10.91
You can figure out the exducer and inducer on this baby.
And then to stir the pot. . .
