What size turbo for 6L v8 (L98) going into a Nissan GU 4wd

[JoelM]

Hey fellas,

This might be an odd question to ask here, but I asked on the Patrol 4x4 forums and someone suggested I ask here aswell, since you guys know alot. I've been searching around on the net but most of the time its just linking me to stuff for the old L98 engines

This engine is going into a Nissan Patrol GU - Image search of the GU, so you know rough size: (http://www.google.com.au/search?q=ni...A8iriAeRuf3eDg) and the wiki page for specs, haha: (http://en.wikipedia.org/wiki/Nissan_Patrol) saves anyone having to do much work!

I recently purchased a 6.0L L98 Engine with 67,000kms on it.
The main issue I have at the moment, is, how can I pick what size turbo to go on it? I've been looking around, and have come up with a couple, but since its not my field I would like a second opinion

Turbonetics GTK-850 (new, cheap from a mate)
or the GT4094 or GT4088R

Will be stock bottom end, not sure what I'm doing with heads yet, they seem to be alright in the L98s though..

Only want about 450~kw or HP, not sure which the 4.5 autos can handle.. And only planning to run about 6-8psi

Thanks in advance if you need anymore info I'll be happy to answer.
