But the car comes with some hybrid turbos. Standard turbos with rebuilt internals that are good for 1.3 bar.
What sorta figures should I expect if I chose to fit them?
it all depends how much boost you want to run/your setup can handle
Well if the turbos can run 1.3 bar, I want to run 1.3 bar. I suppose it just depends on when the fuelling side of things run out of puff?
Anyone any idea?
fueling will run out way before then, im no expert but i would say around 1bar with your injectors but im not sure.
would also need to upgrade a few more things as well
What else would need upgrading apart from the injectors?
Surely everything else is there already?
The only other thing to add to that would be a HKS twin spark, at least that way you should have no problems with ignition breakup at the top end.
you can up the fuel line pressure to give you a bit more fuel, even with uprated internals they will be producing more heat then power past 1.1 BAR.
I know BNRs or Knightsports had bigger wheels, are your twins any of these makes?
at 1 BAR you may get 340bhp at the wheels depends on the porting of your engine as well, you need a twin spark really past 1 BAR
