Aweeesoommee thats a lot better Mikka33 - thats almost identical to what I laid out for the equivalent + a little more (hence $900) as most of the stuff done with mine will be done at home as well A mixture between me, legendary friends and various hookups I can get is something I am hoping will take the edge off it. Cheers! I'll get info from you if I do buy one though, if thats cool? It'll make it a whole lot easier.. :Pimp2:

Ahh excellent, cheers for clearing that up The GT2871R was actually what I liked the look of as an alternative to the GT25/40R... it seems on paper to be very similar, if not identical to the HKS GT-RS. Do you think the GT3071R would could be used without the need to space the turbo out from the block like the GT25/40R does? Or if the GT28/3071R would have the actuator mounted in such a way to cause the kind of issue Mikka33 described, where he had to remount it to fit?

Cheers DiscoPotato03 - I had initially rationalised that the GT25/40R would be a good turbo to go for in terms of a value for money upgrade, so the fact that the GT25/40R is a dinosaur wasn't going to bother me too much - especially when it looks quite cool too But if it is going to cost that much more to fit, it starts looking like the "expensive" alternatives from HKS etc are not that bad afterall. I want to set up a nice and kinda cool "mild" street combination, 400flywheel hp would be plenty to keep me happy and I want to keep away from running over 1bar. I could be mistaken because I am still new to compressor maps etc - but the GT3071R compressor map didn't look a fantastic amount better to me than the GT25/40R, it looked more suited to higher boost (.. and power...) levels whereas just under and up to around 1bar of boost the GT25/40R looked in a higher efficiency area. While in theory the GT3071R is "better" for a RB25DET if you are going to push it harder, I don't really need the 400+hp the turbine could happily flow with the larger turbine so maybe it would be wasted on me - especially for the ~$200-300US higher price tag? Please correct me if I am wrong, I'm still learning I didn't like the idea of the highflow, the turbine housing from the R33 turbo seems horribly small - though if people think they work fine... I could rethink that?! One issue with dealing with GCG is that I am NZ based, and getting stuff sent from Oz is one thing - but sending bits back and forth starts getting to be a bit more of a headache. One thing I have to factor in which would be worth knowing, is I have stock dump+front pipes on the car and they have to be upgraded if I am going for any reasonable amount of power.... so fabricating one to fit a Garrett turbo isn't going to be an extra cost, as I'd have to do it even with an OEM Nissan turbine.

Wow - $1500, thats more than I had anticipated... I had set aside around $900 - not including intake piping as I've budgeted separated for the intercooler etc. When you say custom made, you did the work yourself and it still cost $1500? You have been an awesome help - very very appreciated

Awesome man - thanks for the input What came with the turbo? Did you have much hassle with space, getting oil to it or anything weird like that?

Pro32 - He specified "RB25DET"... As an additional question (hope this is constructive for the guy who started this thread, otherwise - apologies) if one buys the HKS GT2835 "Turbo", what do you receive? Is it JUST the unit? Oil lines, dump pipe, etc will need to be made up additionally?

Yep, that is the one They are asking US$1075 ATP/Garrett GT25/40R

Has anyone tried this combination? I have been thinking of getting one of these with optional T3 flange with .86 turbine a/r for my R33 GTS25t as they are currently available for a very reasonable price from ATPTurbo.com.

Sorry, my bad

Is that referred to me or the GT30 question? I've been searching on GT2540Rs and not been able to find anything

Has anyone tried what HPIAB sell as a "GT28" or the Garrett GT25/40R turbo, or have any thoughts on them? I have been seriously thinking of getting one of those with a .86a/r turbine side with a T3 flange from ATP-Turbo in the US (US$1070) as it seems like a really good value for money (and not to mention cool looking) turbo which I figure would be good for my 250rwkw target with reasonable delivery.

Am I the only person reading this who thinks its a bit lame buying a car just to beat someone?? If you do that, you are destined for disappointment - there is always a biggest fish. Get something ywhich makes you happy, you'll always be the winner at the end of the day if you take it for a drive and don't want to stop.

Interestingly enough I was talking with someone recently about GT28Rs on an RB26 - and they reckoned that unless you go a large turbine a/r (and therefore a pretty laggy twin setup) they are quite "surgey" turbos as a twin turbo configuration. If you are running ~.64 turbine a/r, then what he was telling me is true...

Thats interesting, someone I know insists to me that the "smaller" a/r turbine housing on the GT2871R (.64 or something?!) is susceptable to compressor surge - and is overall too restrictive for an RB25. I'd be all keen for a 2871R, IF it is able to supply up to around 250rwkw on my RB25DET - do you think that would be a realistic hope?

I thought the "Disco Potato" is more like a parallel of the GT2530 in terms of general performance/air flow? If I wanted GT2835-type performance from a Garrett turbo, I'd probably go a GT3071R. You can get one of those in T3 flange, but need to sort out the wastegate control additionally.

That sounds like a relatively normal day - if not a little under average Where abouts in NZ are you? If you are in Auckland, try and make it to one of the drag meets - we have quite a few nasty (or cars which I get the impression are a little more hard to come by in Oz) Japanese cars racing at Champion Dragway... not far from there. Our rotaries are quite average compared to yours - but we have a rich mixture

Ahh ok - wouldn't an equivalent spec TD05 cost similar to a T3, if not cheaper?

There is some kind of Mitsubishi (maybe Trust???) TD06 based turbo for sale on the New Zealand Trademe website which is internally gated and has a T3 flange, and a dump pipe which was bolted on to an RB25DET that I I have been keeping an eye on. It appears the seller may not be aware of what it is....

Hey man - why not have a look at a pair of TD04s? AFAIK they are the same flange pattern as TD05s and they are a dime a dozen here in New Zealand because of people with GSR Lancers upgrading from them to TD05s or bigger. A pair of TD04s leaned on should be able to make around 300awkw and should be pretty tractable as well.

I am pretty sure my S2 Turbo was a Hitachi one...

Holy crap - very impressive, well done!!

I'd take the RZ, no questions. Better motor, better brakes, better handling. I own an R33, but thats due to bang for buck.

Whats the most power anyone has made @ wheels using an R33 turbo? I'm not looking for theoretical ones, because I know what they can conceptually reach - I mean actual dyno'd results. Please specify supporting mods, boost level, and engine it was on . Might settle a debate with someone who is convinced RB20DETs make at least as much power at the same boost level as an RB25DET when running the same turbo.

The least I ever managed to get mine to was 7psi (the R33 electronic boost solenoid raised it to just under 9psi at 4500rpm). Not 100% relevant anyway, I want to know if it'd be safe like this

So - who votes it'd be safe to run a GT-RS on the stock fuel system with an R33 actuator?? What about a 2530Kai or 2535?
