What KamikazeR33 said.
There are loads of cheap shite chinese made Hybrid copies which are rumoured to be garbage.
103mm is serious overkill for use on an R32 GTS-T.
Which one you go for depends on what your prepared to spend. Many like myself would prefer a new japanese complete kit (Complete bolt on - high quality), but if you are happy to consider taking the used route, you could go for a good condition used R33 or R34 GTR cooler which will happily do the job and shop around for a competitive price on the pipework.
Your call, but if buying new, a full japanese made kit will not disappoint.
