R34 Turbo upgrade

R34 Turbo upgrade

Hi guys still new to the fourm and the Nissan scene. Not new to cars I have a handful of bmws and wanted something different. When I bought my R32 GTR my buddy also included a set of R34 GTR turbos. So my question is are they a direct swap ? Also since they aren't in the car yet is there any upgrades I should do to them before installing. I plan to port the factory manifolds when I pull the turbos. Car is running factory ECU with the boost restrictor removed. The car also has a ARC intercooler , HKS intercooler piping full greedy induction kit with apex filters hks down pipes to test pipe to full 3" hks exhaust. I plan on running a apex D standalone just waiting for one to come up for sale used. Total goal I guess you would say Hp would be around 450.

I'm pretty sure Standard GTR 32 turbo has M12x1.25 thread while R34 has 7/16 UNF thread. Oil drain adaptor on the R32 should be 1.75 inches centre to centre while R34 turbos should be in 1.5 inches. water lines are the same and bolt pattern is also the same.

Thank you that's the little stuff that can turn a quick upgrade into a pain in the a#%
