Running E85 On My Car Is It Worth It

I've spoken to a few people with 3L RB's and they've had much bigger gains on E85 due to the higher compression of the 3L. One bloke was telling me how the 26 doesnt have as high compression as the SR's or the RB30. so therefore the 26 can't take as much advantage of the knock resistance of the fuel.

I've had minimal top end gains in my GTR going to E85, only really made gains in the midrange. but i did get it tuned on a hot day and it still made good power. the STD intercooler is probably holding me back.

Am getting it tuned this Thursday, hopefully it will be a little cooler and get some better figures. the tuner tuned it on the richer side just in case it leaned out too much in colder weather.

So hopefully with a cooler day and leaner AFR's i can get a little more out of the car?

If you tune rich there wont be much in the way of gains, my 8.5:1 low compression engine made 50awkw more on e85 with similar boost so your tune is way too safe.

      RB20DE NEO smallbox clutch.

      By Kapr · Posted

      So either way it is gearbox out and look what is wrong?  I know about the input shaft bearing. Even before swap/new clutch the it sounded exactly like this: So is that inout shaft bearing or the other was installed backwards?  And can some please tell me the part number for that input shaft bearing? The gearbox is small box from R34 N/A and number is FS5W71C. Thank you

      I am yet to see anyone ever regret a quaife or helical. ...other than drifting/skidpan duties. I kind of want to upgrade my factory helical with a Quaife (but really it's not ultimately that different, and is a MASSIVE UNDERTAKING), that's how good the hype is about them, that I want to try them 'just to see'

      D2 and Ksport are essentially the same thing and basically just generic Taiwanese manufacture. Better than ChinaBay crap, but... not top shelf. Öhlins have got to be some of the best dampers around, so likely to be a good option. It's going to get to the point though where I suggest you buy from Oz. We have at least 2x excellent options here. If I were you though, I'd be talking to KW about doing something for the R33. There's bugger all difference between that and the 32. In GTR land, anyway.

      KW only offers a set for the R32 GTR. Popular options are D2 racing, Ksport or Öhlins. I have a D2 Racing coilover set, though I don't know for sure which one.

      Well, the good news is you have more than one very good option for new coilovers in and around your country. Worth the drive over to KW to talk about GTR stuff.
