KKK K26/K27 or KX500

[Fredd]

Have two diffrent turbos to chose from after my head change to my s2, Either Hoffer K26/K27 with 6 housing or Kx500 with housing 8

http://www.turboservice.se/KX500.html

Housing 8
inducer diameter 54,8 mm
backwheel diameter 76,0 mm
Polished and flow prepped

Other spec
7a head standard
7a cams
Wagner intake
Furans ex manifold K26
Vems
Simens 630cc
Bosch 044
Big IC

What is the maximum HP of those two ? 430-450 on Hoffer? and 480-500 on KX500 ? what about spool ?
I also think i can change the exhaust side between those two but not 100% sure.

which would you choose and why ?

If the price was similar I'd go for the higher output turbo. Providing it's not a lag monster!

[Fredd]

Have both already

KX500 + E85 (if it's still easily available in Sweden) (and add one more 044 pump )
E85=earlier spool and more power when mapped correctly, think you that know already..
