After lots of fiddling and changing turbos have a tuned result for 28rs on rb20. 219.? on 16 psi.
So seems almost identical to 2530 FYI. Will have dyno chart up soon. Full boost is around 3700rpm Cheers |

3700rpm and 219rwkw sounds nice for 16psi.
 Hows the boost transition? Light switch like or progressive? Get that dyno chart up, one with a boost curve.  -------------------- I use and recommend  |

I reckon it would make some good numbers with big'ish boost stuffed into it
One of these turbo's is on my short list, along with 2530,2535 etc so I want to get a idea what its like with a bit more boost! 20psi is about right I reckon, that way you get good value out of a turbo upgrade If you could post a dyno that would be great! Whats your boost level you have settled for Roy Nice power levels too quincy  I have attached my last dyno sheet, I want to see how it compares to the 2510 running 1.5bar. I reckon this turbo would be great for drift

Well, i have to check, what i thought was 17/18psi on recent track days where i was upping the rev limiter, may actually only be 13/14psi.
I want to be running 17/18psi with ocasional hits of 21psi...suppose i need to get my boost gauge hooked back up. I hope it wsa only 14/15psi that i was running That would mean i ran the times at Sandown and at the drags with only 215rwkws & 14/15psi -------------------- Minister of RB20 propaganda Growing old is mandatory; growing up is optional. |

Keep the thread on track please. GT2860RS on RB20.
Quincy what A/R turbine housing did you choose, and comments on the actual delivery too please!! No doubt this will be a subject of interest to Discopotato03 and others. |

You can see how mine drops away power quick quickly after it makes max power. This dyno is done in 4th, you can see how I want more top end! Very keen to see the results/specs of quincy's 2860 on the RB20 and how it compares to my dyno. Keen to look at other turbo options now |

I am going to stick with 16psi for now - just been stuffing around with it all for the past 3 months so want to keep it safe, very safe for the track.
Asked tuner (Ben) if it has any legs left - his response, "somewhere between another 5-10%" So yes can't wait for 20 odd psi when I could handle the risk of it being off the road again. Dont have a camera at the moment to post up graph, but will ASAP. Troy - I compared to yours when I had the 3071 couple of months ago, it is very similar to yours in mid range, comes on a little earier, and of course runs out earier. Cheers Cam |

Cheers Cam Good man Cam, that was going to be my homework asignment next time i was speaking to Ben. So you are saying the 3071 came on earlier then my setup, but ran out earlier...or do you mean the 28RS  LOL..this is cool, another RB20 on the same dyno with the same good tuner. If there is a better setup out there then lets find it and all go and buy it -------------------- Minister of RB20 propaganda Growing old is mandatory; growing up is optional. |

Wise move running that boost if its going to be used on the track.
Sounds like a good turbo so far, looking forward to comparing dyno sheets and seeing where the 2860 makes power in relation to mine. Good results so far |

3071 coming on earier, Ha ha.. Dog. And didn't run out of puff till 8500rpm. Not much good. So yep mean 28rs.
By the way exhaust housing has to be .64. .86 was laggy and yuk - even though it was advised to get .86 - definatly no good for rb20, must be .64. Anyone wanting some great honest help should see Wayne at GT Auto in croydon - helped me with everything and he was great.

The .64 is fine for the rb20.
Ppls here in SA are running a .63 on their RB25's and making slightly over 300rwkw. -------------------- I use and recommend |
