raz0r$harP.UK Posted October 24, 2006 Share Posted October 24, 2006 what about a T78-33D? or are they borderline BFOT? I'd say a T78 is pretty much BFOT territory, similar to T04Z - and aren't you trying to get around that? If you're looking down the Trust path, TD-07S is smaller. So is it still SST, or are you thinking of something a bit larger?

Steve Posted October 24, 2006 Share Posted October 24, 2006 would go quite well no doubt. I was running 3037s56t on rb25, it was nuts, made well over 300rwkw, made strong boost under 4k rpm - and not one garrett name brand came anywhere near the sort of response/power I was making - infact I have never seen a garrett generic turbo make near the same power/response/toque/spool as the HKS did. (but that is a different topic. On RB26, no doubt the 3037 would be a very sweet thing indeed.

Sydneykid Posted October 24, 2006 Share Posted October 24, 2006 for the twin set-up I want I'd need:HKS 2530s for SST HKS 3037 Not a good comparison, 2530's would get you up around 400 rwkw (not 300 rwkw). I think 2510's would be a better choice if 300 rwkw is your target. But having driven several GTR's with 2530's they would be my choice with around 350 4wkw. They make a NICE circuit car, perhaps why the Mines R34GTR has 2530's on it, as does the re-released Nismo R32 Ztune. cheers Link to comment https://www.sau.com.au/forums/topic/139923-r32-gtr-and-small-single-turbo-sst-upgrade/page/2/#findComment-2611175 Share on other sites More sharing options...

You haven't looked hard enough, GCG supplied GT3040 = 325 rwkw with 1 bar at 3,750 rpm. It's all in the tuning, spend $200 extra on that and save $1K on the turbo cheers Link to comment https://www.sau.com.au/forums/topic/139923-r32-gtr-and-small-single-turbo-sst-upgrade/page/2/#findComment-2611183 Share on other sites More sharing options...
Morgs Posted October 24, 2006 Share Posted October 24, 2006 700HP-GTR33 I certainly hope you're kidding around because thats a ridiculous suggestion that unless they have 2 turbos, a GTR is not a GTR!! Have a look next track day and see how (especially a certain) big single GTRs go. The days of useless BFOTs has passed, there is absolutely no reason a single can't do what twins do. Back on topic T78 is way too BFOT, T04Z is awesome in comparison, 500rwhp @ 19psi with delivery by 4500rpm not being strictly on/off either, with the .81 rear. I'd track back towards something like a GT3037, GT3040 for the lower power level.

Steve Posted October 24, 2006 Share Posted October 24, 2006 yes, well my car was tuned at the same place other guys had their gt30s done - does this mean I could have had alot more than 321? most likely, a japanese mech seemed to think it was a bit low... would love to see a dyno graph for this gt3040, sounds like it worked unusually well, as there was another guy on here who fitted one (gcg) and he hated the thing - ended up going hks 3040 and fell in love.

Blitz Posted October 24, 2006 Share Posted October 24, 2006 As Gary mentioned, for 300rwkw on a twin setup,you want the most efficient turbos you can find so you would either search for a set of HKS GT2510's, or for the newer option, GT-SS's. Both will comfortably reach the power goal and its already a well known fact that for response, its hard to go past GT-SS's, especially at ~$3,000 for a complete kit (Half the cost of the proposed SST setup!)

R31Nismoid Posted October 24, 2006 Share Posted October 24, 2006 The 2510's were a horrid setup from what ive been told by many people. Not a very good turbo at all. The GT-SS is much nicer in terms of its design.

GTR-Ben Posted October 24, 2006 Share Posted October 24, 2006 (edited) Speaking of the GT-SS Turbo. My friend just bought a turbo and was told it was HKS GT-SS turbo. It only has Garrett written on the housing but I don't recall if HKS actually put their name on all HKS turbos? The core has this written on it: HJ 0188J GT S 472560-14 Can anyone confirm?

R31Nismoid Posted October 24, 2006 Share Posted October 24, 2006 There is a thread with the details somewhere, but GT-SS dont have HKS markings, only Garrett... save for the actuator which has a black HKS sticker on it Link to comment https://www.sau.com.au/forums/topic/139923-r32-gtr-and-small-single-turbo-sst-upgrade/page/2/#findComment-2611465 Share on other sites More sharing options...
Beer Baron Posted October 24, 2006 Author Share Posted October 24, 2006 thanks for the input. good to get the SAU brains trust on this one. nick, you are right, HKS GT-SS are the proven option and very good value at $3K, but you do need to factor in twin dumps and front pipes which would be much cheaper on the SST set-up with just one simple dump, and one simple front pipe. Gary, I hear you on the 2530s too. They would be my other choice I think. Morgs, I will heed that advice and put the T78 in the BFOT bag. but definately considering one of the small T04Zs. What housing A/Rs do they come in (both ex and comp). Something around .81 rear and a .60 front could be good depending on physical size/wheel size/trim. Should be good for 350rwkw and hopefully full boost before 4000rpm. basically whatever turbo I end up with I'd want the wastegate (s) cracked open before 4000. otherwise it's not really going to do it for me on street or track for that matter.

Roy Posted October 24, 2006 Share Posted October 24, 2006 Someone lock this thread....too may good ideas floating around. Does anyone know the details of the IHI turbos the Z-Tune uses? If its a track car, then i say stick with low mount twins and std manifolds and heat shields. Controlling the heat with a single and tubular manifold is a bitch on the track. And the heat from a little RB20 setup is going to be less then 300-330rwkws. Agreed, Fernis cars is pretty damn impressive.
