For a start, stock injectors are 440cc. If you put 650cc injectors in there you will have it running pig rich, if it runs at all. You need a programmable ecu to accomodate the larger injectors.

If you tune the ecu for the injectors, it shouldn't use any more fuel for the same amount of power, just that the duty cycle will be lower, ie open less.

      I have to put something here in order to post the photos. From what I could gather there's more enthusiasm for modified cars now than there has been for years. There were probably more younger people there than older (me included lol) which was a good sign.  It did seem like the record least amount of representation of the 90's era hero cars on display though. Like maybe one or two examples of S-chassis Nissans, and maybe 3 or 4 R-chassis. By comparison there were a lot of Civics from that era but in all there were about 10 - 12 EG/EK Civic Type R.  Euro exotics are always there in large numbers, led by Liberty Walk...... say what you will about kids using markers to scribble on a Ferrari F40, it did seem like a stunt to infuriate Ferrari enthusiasts, or Ferrari itself. I wonder if there's something more to it. Either way LBWK have done some heinous things to a Lamborghini Miura this time. They should stop now.

      Engines and drivelines are not war stoppers for me mate, busted arse bodies and un-obtainium parts and panels are though Both cheap Brumbies I looked at had trashed tubs and a fair bit of rust

      Stock O2 sensors are narrowband. They're useless once you're away from stoich. IE, useless for what you're trying to do. 10:1 will read the same as 14:1 from the stock O2 sensors. That is, they'll read rich. The same level of rich.

      I agree once misfires happen it's basically worthless, but the hope is you can see what's happening in the run up to that.

      You should totally get a Brumby, and then come pick up the Subaru Liberty GTB I have here. EJ25 Turbo, 6 speed manual from the sti (just no dccd), and the good rear diff. Drop all that into a Brumby and go have fun!
