Me too. I'm looking at upgrading to either R34 n1s $3200 or HKS GT-SS $4200.
My aim is for a jack of all trades street car for daily driving, and the odd drag and track session.
I have the support stuff in place, nismo pump, 720cc injectors, no airflowmeters, front pipes big fmic etc.
Dump pipes would go in once the current R33 n1 turbos are taken out.
Just want to update turbos to ball bearing for more response and power.
I liked the power that the n1's put out, but my aim is for around 350+kw at the wheels with more response. So it's down to 34n1s or GT-SS. Have read the whole topic and it helps a fair bit, but I need more info on driveability in varying conditions, use.
