your options are limited by your jabba mani/install

do owens offer a GTX2867 version of their ihi framed turbo?
 
Have a look at Turbo Dynamics MDX555 range im running one on my Jabba manifold and downpipe
 
Id say spool up is very good.

what are the sc36 turbos like? scooby clinic

Cant comment on scooby clinic range of turbo as iv never seen them on a 1.8t but their turbos are Blouch ones so your better off ordering it from them directly and it will be cheaper.
 
If you run a VF34 or VF22 dont go crazy with the boost and chasing BHP figures and you should be ok.
 
what sort of figures did u have on your vf22?

330bhp, the VF22 is more laggy then the VF34 but not that noticable also I had the p20 exhaust housing on mine which means more lag but higher peak power.
