  1. I got just shy of 500hp with a fairly tame -5 setup + e85 (details + dyno in build thread in sig if your interested), based on a recent tear down it's likely not all cylinders were round at the time ?

    Best thing about e85 compared to 98 was filled all the shortcomings of the low-mid range the setup had, it took a fun, but laggy setup to something very usable in all situations.

    Car should be back in a couple of weeks as most of the work is done now, so will be interesting to see what a fresh 2.6 with only a mild compression bump produces in comparison.

  2. I know there's a general dislike around the joint for twin setups, but given the hit and miss results of the GTX series, I'm interested to see what results come out of the woodwork for the G series.

    ...and if that fails, how good this series (larger frames) are in single config :)

  3. I'm running -5s on e85 (flex setup) with Tomei Type Bs.
    They're a bit average on on 98 alone, but e85 really wakes the turbos up, mid range and boost response improved very noticeably from seat of my pants view.

    I'm boost limited due to an otherwise high km stock motor, a forged build with more boost would be pretty good thing with this setup IMO.

  4. I'lll post up my -5 result later when Photobucket is back up (in my showcase below if I forget), but Ambi3nce's -9 result looks very similar to my -5 result.

    Main difference looks to be power band is on 300-500rpm sooner, and ~15% more peak torque ! (520 vs 605)

    Same boost, same peak power, same ecu, same cams, same fuel, same workshop, same tuner/dyno.

    ...not sure if you could get much closer in terms of setup for comparison?

    Headstuds & more boost should widen the gap between -5 & -9s in the top end though.

  5. Besides the point, given it was probably a $50 block to start off with. The issue is that rare that it shouldn't even be a consideration for choosing between an rb30 compared to the rd28.

    OP, there is a guy building up an rd28 block on these forums with a white r33 gts-t. Might be worth digging around and PM'ing him about the costs of machining the block.

    Not in Australia or NZ etc, but determinately in Europe where shipping a rb30 block is prohibitively expensive.

    Topspeed in the Ukraine had an RD28 based RB26/30 combo in their 7 second R32 GTR, well at least until they put a VR38 in there LOL
