Hey all was wondering wat turbo would be better for a street application wit the ability to goto the track an tear it up on a weekend?? i currently have the gt2860 (-7) an am makin 450hp atw.. are they capable of more?? cause they have amazing response an make a nice street car.. or would it be appropriate to bump up to something bigger such as the gt-rs! to see atw figures of 500-550hp. An are the gt-rs really as laggy as ever1 makes them out to be??

thanks korey

Are you on a stock stoke 26? If so i dont think RS's would be the right turbo for a street set up. Even myself on a high compression 2.8 litre im sometimes wishing for slightly smaller turbo's because im caught "off boost".... Gets retuned this week so see how much better it is. 2530's at the biggest on a stock motor IMO.

Well that was the other option the hks stroker 2.8lt, but your sayin that your even caught off boost occasionally wit that set-up?? i was talkin about the 2.6 but strokin it was another option if i went the Gt-rs.. wat are the 2530's equivelent to?? the gt-ss?? the gt2860's are slightly larger yeah? with the set up your runnin being stroked wat rpm is boost coming on wit the gt-rs's on??

Last tune it was 1.65 bar at 4700 RPM. However, I will reply again on friday and its getting retuned. Alot of stuff has changed (catback, plenum, boost controller, better cat) so I have a feeling this will drop a few hundred RPM. The catback made a HUGE difference (kakimoto Full Mega N1) Its going as good as what it was before on 1.3 bar. Going up a hill in 2nd gear with 3 people in the car and jump on the loud pedal at 6500 RPM and it will break traction. Give me 5 days :(

Mate - ive said before... Please use the search.

GT-SS, GT-RS and every other bolt on turbo from garrett/hks for a RB26 is soooo well covered you really need to do a bit of your own homework rather than have people spoon feed you.

Once you do search, you will find there is a turbo in between GT-SS & GT-RS - The Garrett "-5"/HKS 2530... more info on that specific turbo than any other on the forum

Thanks.

      Haha no I'll do that one tomorrow. I've been ignoring it. It's the 5.0 one I'm taking about. (There is a little X to hide the 4.7 one if you want)

      So I'm going to have to keep ignoring the 4.7 update, or whatever version it is? Poop. I was hoping you'd put me out of my misery.

      We have a huge update coming in the next few months, version 5 of Invision will be released. I'm holding off any changes until after this change as I'm not sure what features will be removed or introduced.

      Yeah, plenty of air flow, there is a dedicated path that feeds the air in to the OEM intake tube behind the bumper As for a "tangible effect", maybe, but getting the pod/intake air out of the hot engine bay is worth it psychologically to me, even if it gives no performance difference, so the tangible effect in my Lizard brain saysss yessss  In the end, to me a tangible effect isn't always about performance, sometimes it a sound or a look, or even a...... feeling  Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga

      yeah first and reverse is where you will find clutch release issues (whether hydraulic or mechanical) because the difference in revs required is the highest there; particularly changing down from 2nd to 1st when still moving. To be clearer though, it is possible that the clutch release bearing is the wrong height. This is less likely than a hydraulic issue but it is not unheard of when you are mixing and matching
