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.....

      Wheel Sizes & Offsets For Skylines

      If only it were that easy! I also needed to remove seats, shocks, brake calipers, send my car through a fence, and use measuring and ended up guessing because I didn't remove seats, shocks and brake calipers. It can be hard sometimes Can be a little more complex than 'just measure' if you want to truly measure the entire wheel through all of it's suspension travel. But if you aren't going for every last mm then yeah, you can check the space you currently have and guesstimate.

      If you own a car, and it has wheels on it, and you know the offset of those wheels, and you have a measuring device, you have everything you need to work out if other wheels will fit.

      MAJOR FUEL ISSUES 25det neo r32

      By MBS206 · Posted

      Put a clamp on your return line. I have a feeling it's sucking air, and introducing bubbles to your fuel. With a lot of fuel, less problematic. I'd honestly be redoing all the lines in the tank and clamps on everything.   Also, you've given two different answers to the same question: Asked if being followed by the police you could get down to use the whole tank, you said yes you could, so long as you keep off boost. However, you then followed this up that free revving, it would also cause the issues. I'm doubting free revving is enough to make any noticeable boost on what is likely a decent sized turbo.   So now I have to ask, can you actually drive it lightly and use all the fuel, or does it break up even free revving? Also, have you put a fuel pressure gauge on it? Can you hear the pump change noise at all when you're having this issue?
