Turbos are fine, just a bit old school as the hipsters have diluted their gtr purity and gone for singles. They are still good units, however and the blokes with ponytails and beige Volvo dailies can get stuffed.
‘The ecu is a good ecu. You just need a good tuna to tune it. My point wasn’t to put down the setup just to highlight you need someone familiar with rb’s and their idiosyncrasies.
.3:1 isn’t earth shattering on the cr. Certainly nothing E85 won’t compensate for in spades if you go that way.
So yeah don’t get negative about it. It will work fine and be loads of fun. FWIW I’ve got -5 turbos and a Link ecu.
