K24 vs. K26 vs. RS2
I just read a few "supersonic turbos" threads, and of course, I'm now more
confused than before. Here are my impressions, please correct me (Scott J.
aka QSHIPQ esp) where appropriate.
The K24 is a good 'low-end' turbo. Comes on at 2,000 rpm, can handle 1.8
bar (12-13lbs) no problem. Will increase a K26 based MC's low end nicely.
May be a problem at higher rpms (don't know at what rpms). An inexpensive
solution (w/a good used K24) to low-end problems on a slightly modified
(e.g. QLCC) car. Not real good for turbo mods or for higher boost levels.
The K26 is good for higher level of boost (up to 18 lbs), with a low end
penalty. Needs 3,000+ rpm to really start boosting. An IC can help, but
not solve, the low-end problem. Also good at higher rpm ranges. Can be
readily modified to provide better low-end boost. Around $800 and up to
The RS2 turbo seems to try to be the best of both worlds. Good low-end
boost (not as good as a K24, much better than a K26), and great high rpm
boost ability. Comes with a price penalty. $2,000.
My .02. Tech nerds please fire at will.
