Question is can I do it or will it run like shite? Bascially I have a HKS turbo to fit to my RB20 but as I haven't got the cash at the mo for a decent ecu and mapping I'm thinking about putting the standard turbo back on for a while.
Thing is I have done all the work to fit the GTRs, wired in the resistor pack had them cleaned etc. So would I still be able to run them with the standard ecu or is it going to do more halm than good?
Would fitting a z32 help also? If you fit these on a standard ecu don't they make the engine run lean? Would one offset the other?
