Ok, so what about HKS GT-RS and GT-SS? which is better again? and out of these four turbos, which one is the best out of them all? Cuz I am thinking of upgrading my turbo, but just dont know which one to go for.

GT2540 is just a bad turbo all round, far too much compressor for the turbine to handle.

GTRS is similar, but no where near as bad. Have a look in the forced induction section at other people's choices.

I have Gt2560r-9's, they are awesome building good boost from about 3000rpm, full boost/22psi by 4000rpm. It makes 308awkw at 5000rpm and peaks with 368awkw from 6500rpm and holds strong to redline. I will be putting it on the dyno on tuesday once the new gearbox is in to check it's tune before summer so i will post a dyno sheet.

Which one is best? For what? You need to describe what the car will be used for & what you are looking for. Is it for a road, track,dyno or drag car? Are you chasing high kW at the expense of lag or do you want something that's responsive? How much are you willing to spend? What mods do you have already? Is the car running standard internals?

Check out this thread (as salad advised): http://www.skylinesaustralia.com/forums/t93880.html

There are heaps of threads on this in the Forced Induction section but don't start a new one without doing a search and some reading first or you will be either ignored or flamed. These charts may help (which were in the Forced Induction section and are discussed there).

Personally I went with HKS GTSS which are probably the best (along with N1 & Garrett GT2860R-7) for a street driven GTR but that lead to needing heaps more stuff and many, many more $.

GT2560R-5 (707160) 1bar boost @ 4050rpm.

380rwkw pump fuel(BP98)

413rwkw jungle juice

707160-5 is actually a 2860 where as 707160-9 is a 2560 which are the same as i am running. How much boost are you running? Will post up my rwkw figures at 22psi on tuesday.

My title says it's for R33 GTR, a responsive 600hp @ engine street GTR, the car has got straight-thru exhaust and pods, putting power fc into it when I get it etc, and hopefully I won't need to touch the internals. Hopefully can get everything done for as little as 5000 or 6000AUD.

Hmm. Used to have 33 N1's(300RWKW), Then I put 2530's on my GTR. (stock innards with pomcams).

17psi@4800 to 8000+ =###rwkw

GTSS will get around at least 350RWKW with cams with lots of response.

GTRS will get around 400RWKW with supporting mods with stock bottom end and cams.

Just a rough guide.....

i got the usual mods like fmic (stock gtr one), exhaust, dumps, de cat, pfc, sbc i colour, pod filters, 700cc injectors, 044 fuel pump,hks cam gears, splitfires and an oil cooler, how much power should i expecting if i get N1's, GTRS, or GTSS?

Is that meant to say 17psi@4800 to 8000+ =333rwkW?

      RB25DE NEO with Haltech ECU

      I guess one thing that might be wrong is the manifold pressure.  It is a constant -5.9 and never moves even under 100% throttle and load.  I would expect it to atleast go to 0 correct?  It's doing this with the OEM MAP as well as the ECU vacuum sensor. When trying to tune the base map under load the crosshairs only climb vertically with RPM, but always in the -5.9 column.

      AHHHH gotchaa, I'll do that once I am home again. I tried doing the harness with the multimeter but it seems the car needed a jump, there was no power when it was in the "ON" position. Not sure if I should use car battery jump starter or if its because the stuff that has been disconnect the car just does send power.

      As far as I can tell I have everything properly set in the Haltech software for engine size, injector data, all sensors seem to be reporting proper numbers.  If I change any injector details it doesnt run right.    Changing the base map is having the biggest change in response, im not sure how people are saying it doesnt really matter.  I'm guessing under normal conditions the ECU is able to self adjust and keep everything smooth.   Right now my best performance is happening by lowering the base map just enough to where the ECU us doing short term cut of about 45% to reach the target Lambda of 14.7.  That way when I start putting load on it still has high enough fuel map to not be so lean.  After 2500 rpm I raised the base map to what would be really rich at no load, but still helps with the lean spots on load.  I figure I don't have much reason to be above 2500rpm with no load.  When watching other videos it seems their target is reached much faster than mine.  Mine takes forever to adjust and reach the target. My next few days will be spent making sure timing is good, it was running fine before doing the ECU and DBW swap, but want to verify.  I'll also probably swap in the new injectors I bought as well as a walbro 255 pump.

      spot the stagea

      It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack.

      Probably not. A workshop grade scantool is my go to for proper Consult interrogation. Any workshop grade tool should do it. Just go to a workshop.
