Hey there, I just bought my first Infinity, 1991 G20, I really love the car. Here's basically what I know:
10:1 comp JDM highport SR20DE, header, full 2.5" exhaust, B14 SE-R 5spd LSD trans, K-Sport adjustable coils, 16" Enkie 2 piece JDM wheels, drilled and slotted rotors all the way around, cusco fstb, Adcco rear sway bar, full G20t interior swap, Nissan Primera GT EDM cluster, Primera EDM Taillights, Visors, fender turn signals, and trunk spoiler, 4500k HIDs, alpine deck with Infinity Kappa all around with JL 12, tinted.
I absolutely love this car, twice as fun to drive as the 86 IROC I sold to buy it, and that car was far from stock too.
I do have a couple issues, drivers seat has a tear, one of the K-Sports needs rebuilt as the adjustments are all seized, the passenger axle is weak, not an LSD one, I got an LSD one already, but don't have the right carrier.
