Difference Between A Garrett 2530 And Hks 2530!

[Munkyb0y]

read the last post on page one mate, the GTRS is a 2871 52T in HKS housings. the 2535 has yet to be mentioned.

yeah that's nice. But it doesnt tell me where the HKS 2535 fits in. afaik it falls about 15kw short of a gt-rs, with killer response.

so what is it's garrett equiv? just how much smaller is it than the 2871.

if the 2530 is good bang for buck, but somewhat underpowered, and the gt-rs is a great performer, but way overpriced, the 2535 should be Goldilocks' pick.

Just breifly , work to do , the HKS "GT2535" has a 69 x 51.6mm 56 trim compressor wheel . Judging by the barb sizes the compressor housing is probably the same as a "GT2530" , T04B 0.60 A/R . Note these housings can be the truck or Nissan style .

My lists show the power ratings of the 2530/2535/2540 as 320/340/350 PS , PS is supposed to be very close to HP figures .

The GT2871R's use a 71.1mm compressor in 48/52/56 trims , the GTRS has the 52T one .

Gotta scram , cheers A .

I'll give the cartridge number later .

I cant match that 2535 compressor to anything else on the garrett site, interesting.

as for being more responsive la la la, somehow i dont think the GTRS will come accross laggy in the slightest... i wish i could have the HKS GTRS housing and the housing off the HPIAB "RB special 2871" to compare.... if the housing is built to be the correct AR for that actual turbine and not a ground out RB housing that could be a very potent turbo.

tho to point out.. HPIAB sell that turbo for nearly 2k on its own... the GTRS kit comes complete with all the gear ready for bolt on for 3k... its not THAT much of a hike for guaranteed results

pretty sure that the HKS GT2535 comes with a 0.8x rear housing (not sure if it's them all or it's a option)

Now that threw a spanner into the works, ive wanted to see a .8x hotside on that sort of turbo matched to an RB25 for a while now... shame garrett dont product a T3 footprint 2871 from the box, the available T2 comes with both .64 and .86

So build a GT2871 52T in a .86 T28 turbine housing with OEM nissan rb25det pattern would be very similar to a GT2540?

I do not think that combination would be very similar, but if you made one, I would want it.

I think the above said combo would be better than a GT2540, and possibly even able to use a 56T.

As promised the GT2535's cartridge number is 446179-19 .

Garrett actually make two 69mm OD compressor wheels in the T3 family .

Part No 446279-0001 69mm x 51.65 56 trim 6.2mm tip height . Normally its bore size is 6.25mm but can be made smaller to suit the GT25BB center sections turbine shaft .

Part No 466279-0002 is 69mm 46 trim .

Both are 6/12 bladed .

Personally I think its easier these days to use the GT2871R cartridges because they are readily available . The 56 compressor trim version is known to be a bit lazy/laggy so I'd say its wise to avoid them if response means anything to you .

My HKS list is not complete and shows a couple of cartridges not identified - 446179-17 and -20 . Pretty sure they would be the GT2510 and GT2540 .

wow a wealth of information in here and I finally find out my turbo is a HKS after a few months of owning it.

If anybody is interested I have a HKS 2530 with the garret front cover with braided lines in Adelaide for $1300

[Brad_32]

howd the 2530 go man?? i cant put mine on for lik 6 months until my motor is rebuilt! but not sure now on how the go lol. make good power??? also might have a might keen on buyin that turbo i live in the hills so not to far out but will let you know if hes keen!

[discopotato03]

Really for a single turbo Skyline the important part of those HKS bolt on turbos is the turbine housing . I think the 0.64 A/R T3 flanged HKS housing is common to the 2510/2530/2535/2540/GTRS turbochargers - the RB20/25 spec ones .

Note you would have to have one off a 2510 re profiled to suit the larger turbine used in the other four turbos .

Also note HKS replaced the old 2510 with the non GTR spec GTSS . It has the larger GT28 turbine with the same diameter compressor wheel as a 2510 or 2530 but in 60 rather than 63 trim . Cartridge number 446179-53 .

Theres nothing to stop you using that housing on any of the Garrett GT28 BB based turbos using that same larger GT28 turbine ie a GT2860RS .

very intrested and good information

Somehow i doubt GCG would stock such an item lol

[discopotato03]

In the past I have seen HKS turbine housings at GCG but don't know about the T3 flanged GT28 one .

It goes against the grain but you can possibly achieve much of the same thing with the Hitachi OP6 type housing and a bit of machining . The 76T GT28 turbine is a little larger than the Hitachi ceramic one and people have used this housing on Garrett BB cartridges at times .

Maybe even the RB25 Hitachis turbine housing could be used at a pinch , would keep the mounting and dump flanges in the RB family .

RB25 BB Hi Flows make if anything a little more power than a HKS bolt on GT2530 so the flow through them can't be too sad .

Plus there like ars* holes , every 25T has one ...

Someone here had a Hi Flow made up out of an RB25 Hitachis housings and a GT2871R 48T cartridge . Real good mild dryer from memory .

[GTScotT]

perhaps the AVO .71 would be an interesting venture then

probably a better option to supply that to GCG and have them profile it up for the 2871 cartridge rather than the HPIAB kinder surprise.. you think a 2871 56T would make the hotside hit a brick wall in the AVO .71 housing? considering they rate it capable of running GT30 series wheels, it would be fairly irresponsible to rate a product as compatible if it couldnt flow that kind of gas.

[discopotato03]

I'm not sure with these aftermarket turbine housings , I think its a big call to say they can work well with GT28 or GT30 sized turbines and just machine to suit . GCG decided to stop putting GT30 turbines in them because too many people had boost creep issues .

I think you have a bit of room to manoeuver machining Hitachi housings for GT28 turbines but GT30 based turbines need GT30 based turbine housings .

If you look at A GT30 housing you can see that they are not only larger in diameter than a GT28 but wider through the volute as well . I dunno but it possibly has something to do with the wider tips on a GT30 turbine and that the wheel itself is physically deeper than a GT28 turbine .

For whatever reason the GT28 turbine 56 trim 71.1mm compressor is not a good combination response wise . I think the mass off the air that compressor can pump is too great a workload for this turbine and they tend to be laggy on most things . HKS stayed with the 52 compressor trim cartridge in their GTRS and only went with the 56T wheel in their "GT2835" which we know uses the slightly larger cropped GT30 turbine .

Note they didn't use the full sized GT30 turbine here like Garrett did in the GT3071R (700177-23 CHRA) so maybe they though it wouldn't spin the 71.1mm compressor fast enough to be "responsive" .

For RB's HKS seemed to nail it with the GTRS and 2835 Pro S but they did use non garrett hosings both sides in both cases .

Maybe someone needs to ring the machine shop in China and ask them to reset their machines so we can have some T3 flanged GT30 IW turbine housings for the cropped GT30 turbine . Then we can use these cropped GT3071R AKA 2835 cartridges on RB's to plug the gap between GT2871R turbos and GT3076R's , and not have to pay a HKS GT Pro S price for it .

lol ill call china now, i know how to say larp sarp (trash) bong o da fei gei (help me smack the aeroplane aka pull my deck) and mo gai (no alternative).

Surely I can string something together to the tune of "HKS housing" because the ones we have are larp sarp and when they decline Ill say mo gai and before I hang up in hostility ill ask the cute sounding receptionist if she can bong o da fei gei.

Wish me luck.

What about the GT2530Kai? Is it rated to more power than the standard 2530, as the pro s is to the standard 2835?

[Kwyjibo]

That is exactly what I have:) Perfect turbo for an RB20.

[White GTS-T]

Awesome, that's good to know. I can't wait to get it on and tuned. Do you know if the spec and trims are the same as the previous model? As in what's the difference between a 2530 and a 2530kai?
