Nismo N1 turbo's vs standard gt-r turbos

[summoner]

Anyone done this swap on their car with a before and after dyno run and graphs?

What is the main differance on these turbo's? steel wheels? compressor/exhaust housing sizes? Any information on these turbo's would be great thanks.

boosted_rb26 has n1's on his, pm him for info dude

larger housings , larger compressor and turbine wheels ( larger too) spoll up 1000 rpm later , i just done the swap when i tune the power fc i'll let u know if they are any better .if i was you i would steel wheel and hi flow the original ones unless u want to mod for big hp

i have turbo back exhaust 1.2 bar boost and power fc , have to tune again as it runs very rich now . i had these rebuild by garrett new shafts and new cores . i get full boost at 5000 -5500 in 2nd and 4700-5000 in 3rd
