exhuausts are identical really to any 350z. To me the HRs setup is really not beefed up for a FI application more as enchanced for a higher reving NA engine. Its a high compression motor the mods really are designed from the way it looks to get the most out of it NA wise.

Look at teh vq35der (revup)
basically 30% percent different just for a increased rev limiter and top end.

it takes alot of modifications to not only make the power nessesary but nissan also has a great track record with this engine, ...and i doubt it will be the GTRs engine directly )3.5) because simply put it.. They have better bored out versions of the HR already. the 3.7 the 3.8 it wouldnt make sense to go with the current 3.5 at all.

 

Just figured out who this is... lol...

I live in CA with the tree-huggers. They hates Turbos for whatever reason...
