Im tossing up between a couple of options for turbo/s on my RB26/30 I am currently building. I am considering running a pair of turbos such as these:
GT32 73 Trim .78A/R (externally gated versions)
Turbo specs
As these are non ball bearing turbos, will there be a noticeable difference compared to ball bearing versions in spool time?
Will these be able to flow enough for 400 rwkw through an 3 sp auto? Rest of ancillaries will be up to spec. Or should I just stick to something like a single GT40 BB turbo?
Any help appreciated.
