lol the AR is 'aspect ratio', not specific to a unit of measurement as such (ie inch or cm).

As for the comparison to 2835... The 2835 is nothing like your other 2 options... Its actually a 3071 with a cropped exhaust wheel.. The 2871 is something completely different.

So far my RB26/30 with 272 deg/10.5mm jun cams and hks 2530's are promising and may fit your bill, time and a final tune (currently on run-in) will tell.

oh yes please, i have hks step 2 cams 270/280 10.2mm lift, ported head.. r u using std manifolds or tomei etc.. graphs and thougts would be mostwelcome mate.. also are they genuine hks 25/30,s or equivelent..just to get it right..

Standard OEM manifolds with the turbo flange ported to match the turbo.

Also split flange dump pipes (dodgy ebay ones that we had to hit with a hammer to make fit...)

and a trust front pipe, high flow cat, HKS zorst.

Genuine HKS branded 2530's with HKS wastegate actuators.

Will post up dyno charts in my main build thread when I get them.

      That looks good, but I think you're going to need much beefier side skirts now.

      They are daft and there's a reason it never caught on. Steering feel? We don't need no stinking steering feel!

      new 1.5 LSD issues/concerns

      By GTSBoy · Posted

      I gotta pull you up on this. It's driving me crazy. A shutter is something that closes, like over a window or in a cmera. The word you want is shudder. That LSD is clearly f**ked. Take it to a diff shop and get it disassembled and examined by an expert. YOu might have plates welded together or something equally crazy.

      S1 rb25/s14 starting problem

      By GTSBoy · Posted

      Check the Nistune doco. There are a few assumptions being made here that might not be valid. I will list the things that occur to me: Base map. Base map for what? Base map for Z32? Then the cranking pulse width is probably wrong for an RB25. The extra 500cc of capacity might well be enough to prevent it from catching. Base map for RB25? I don't think you can load one of those into a Z32. You have to just make the settings correct for an RB25 in the Z32 base map. That is either K or the TIM to get the pulsewidth right. Loom. You bought a loom for an RB. And you plugged it into a Z32 ECU. Did you make sure that any iwre differences were swapped. From memory, there's at least a couple. And as per the others, I would suggest making sure that the fuel pressure is correct while cranking and that the injectors are actually flowing as expected. They really must come out and go on the bench, unless you do find that you have messed up as per above points. I would also suggest watching in Nistune to make sure that everything is reading correctly. That the correct binary flags are raised at the right time (like the crank signal), that there's no stupid values in K or TIM. That you have not got mismatched firmware for the ECU and/or a wrong image loaded.
