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.

      I'd be worried about having to parallel park a boat like that. Magnificent car though.

      This car has run before on this z32 ecu can get the part number for you, I have tried with no AFM it didn’t change anything, I compression tested today 140-150 across all 6 cylinders, also set fuel pressure to 43psi. The only weird thing was cylinder 1 plug was black and fouled other 5 cylinders were just wet with fuel. Spun cas by hand and confirmed injectors are clicking

      Since you came here to ask for help, have you thought about answering our questions, that might help us lead you to why it was skipping, or have you given up on getting advice?

      A 1.5 way is a 2 way. It is just a 2 way with a less aggressive ramp on overrun.

      Boost cut after swap(RB25DET NEO) R34

      By GTSBoy · Posted

      The ABS and/or TCS being missing/broken will not cause the engine to misbehave. It just casues CEL to come on and annoy you. The CEL is useless if it is always on, so you have to do the things you have to do to get rid of it, so it can be useful. Being a Stag ECU, then yes, it will not expect TCS to be present. But it will expect ABS to be present and working. You will need to either make the ABS CU talk to the ECU (don't ask me what that will take on an NA R34), and make sure the hardware is working....or, you just need to blank it out in Nistune. Do not persist with the stock ECU. You will just have problems. Gte it Nistuned. Start from there. DO YOU HAVE A BOOST SENSOR? The ECU's boost sensor that it. It is connected to the loom at the rear of the coil cover. Usually rides on the firewall on an R34, but is usually bolted down to a bracket along with all the other crap at the back of the coil cover when a Neo is dropped into another car. If you do not have it, the ECU will shit the bed. So, do you have one?
