I have a R33 GTS-t and currently have the following setup:
Turbo back exhaust
Hiflow filter for stock air box
An oriface from benl1981 which gives me 10.5-11psi boost (depending on wat gear I am in) - http://www.skylinesaustralia.com/forums/sh...ead.php?t=70006
And have a powerfc that I have yet to put into my car
I have the following questions:
When I put the powerfc and do the tune will I need any upgraded components eg fuel pump, injectors etc?
What kind of numbers should I expect after tuning given the above setup?
I know that at some point that will need a few more fuel system/ clutch upgrades. How my rwkw is that when I need to worry about that stuff?
If I am getting to this level, I don’t want to upgrade these at this stage so I intend to tune if for lower octane fuel. Is this possible?
Would I get much benefit from an electronic boost controller and if I do get this later will I need a retune?
Also thinking of putting a R34 GTT intercooler on the thing. What numbers will be getting then?
Again will I need a retune for that?
If I changed my muffler to a less noisy one will I need a retune?
When do you need a retune – how necessary are retunes for new componentry?
