I am just looking to get my facts straight, no offense intended...
> The K numbers refer to the turbine side
There are two turbines on a "turbo". I assume you mean the hot side is
referred to by the "K" number, although I can't reconcile that with what is
below. Personally, I think the K24 designation of the RS2 turbo was picked
by random chance. It was a toss up between a K24 and a K26, and none of the
Germans like Javad's idea of a K25 :-)
> The RS2 turbo IS a K24 with special K26 compressor housing. . .
Yes, the part number for the RS2 turbo starts with K24, as do at least a
half dozen other turbos from KKK.
> How is the RS2 turbo different from the "stock" K24?
> Larger shaft for greater high rpm stability
> Larger bearings
> Larger compressor
> Same exducer diameter as "stock" K26
> Inducer is larger than both "stock" K24 & K26
> So "stock" K26 has its own built in restrictor
> "Stock" K24 does not have enough metal to bore out.
> Before the RS2 turbo tuners would sleeve a K26 compressor
> and then machine it larger
> Larger exducer from the turbine
> More lag
> That is why we offer a special model

I am a hot side/cold side student :-) I am assuming that the inducer is the
cold side and the exducer is the hot side?
