Alternative to the discontinued 2530s?

[GTR-Zilla]

http://www.horsepowerinabox.com/HPIAB2/category12_1.htm

seems very close to the 2350's in both the compressor and turbine trims..

works out about £1000 for 2 turbos

any one have any views or oppinons on these units? what do hks do with the garret units? just stamp they badge? or do they use higher quality materials and charge a premuim?

That does seem cheap in comparison to HKS 2530's & GT-SS's. I'd be interested to see if anyone has used them on here.

They look like N1 turbo,s from the spec and the picture.

IMHO no way 640bhp on a GTR.

HKS turbo,s are developed for HKS by Garrett normally takes around 18months to 2 yrs before Garrett sell the same stuff to the Garrett dealers.

If they are of similar or identical quality and spec as the HKS branded turbo's, then they do seem a bargain.

(this post is based on my very limited knowledge of the cost of HKS turbo's )

[GTR-Zilla]

has anyone got a link to the spec sheet of the hks turbos?

The Garrett rough equivalent to the 2530 is supposed to be the GT2860R. Heres a good thread for you from one of the Oz forums :

http://www.skylinesaustralia.com/for...=80624&hl=2860

and heres the specs on Garretts website :

http://www.turbobygarrett.com/turbob...R_707160_5.htm

I'm looking at a pair of these myself at the moment, if they're as good as the guys on the thread say they are then they're a bit of a bargain

[GTR-Zilla]

To avoid confusion I think we should probably get more specific. I believe the turbo we are referring to is 707160-5. Correct me if I am wrong, but the specs are:

TURBINE:
Wheel = 53.8mm
Trim = 76
A/R = 0.64

COMPRESSOR:
Trim = 62
Inducer = 47.2
Exducer = 60.0
A/R = 0.60

According to Garrett and GCG the 707160-5 is called the GT2860 not the GT2560. The 2560 name seems to be incorrect (and confusing ).

By way of comparison, the stats for the HKS GT-SS are:

TURBINE:
Wheel = 53.85mm
Trim = 62
A/R = 0.64

COMPRESSOR:
Trim = 56
Inducer = 44.46
Exducer = 59.41
A/R = 0.42

And for the HKS GT2530:

TURBINE:
Wheel = 53.8mm
Trim = 76
A/R = 0.64

COMPRESSOR:
Trim = 63
Inducer = 47.7
Exducer = 60.1
A/R = 0.60

Again, if I got anything incorrect say so. Does anyone have stats for the R34 N1s? From the figures it would seem to me the GT2860 is extremely similar to the HKS 2530, but there are significant differences when compared to the GT-SS (at least in terms of specifications, if not final outcome).

Interesting! very very close to the HKS 2530's

Hmmm, interesting......

Being from the Australian forum, I can tell you a lot of people are interested in the Garrett version of the HKS spec turbos. Now we all know that being as HKS have a contract with Garrett for the supply of specific turbos configurations, do you think garrett would a) sell the same turbos specified as per a major customer & b) be stupid enough to risk millions in a breach of contract and intellectual property!?!?!? COURSE NOT!!!!

No way do the generic garretts directly compare with the HKS researched GT series of turbos. I've seen lots of cheap talk on the Oz forum abouth the garrett versions, but when it comes to the dyno they go quiet.....

Guess that is the reason I coughed up the extra $$$ for genuine HKS development and research on the car I own....

As for horse power in a box, I have heard they are copies made in china that don't last in sustained use - hence the price...

Does no-one remember the old saying - you get what you pay for???

im having garreth 2560r's fitted soon on my bnr32,will post some dyno sheets. I think theyre rated at 300hp each so should be responsive

Granted they're not going to be exactly the same turbo as an HKS 2530 (as you say HKS would rightly give Garrett a bit of a kicking if they were) there is a major price difference between the two.

You can buy the Garretts for about £1200 in the UK whereas a pair of HKS 2530's from Nengun are more like £1700 shipped + potentially 25% taxes on landing + actuators as they've recently stopped including them with the turbos.

Are the HKS turbos worth the hefty premium ? For the price difference (and some change) you could get a pair of Tomei Poncams that would probably more than compensate for any marginal differences in spool and power.

It would be really interesting to see a dyno comparison of two cars with similar specs and the 2530's vs the 2860r's.

[OzzieGTR]

The car in skylines australia has not backed up its power at the Drags running near 1/2 sec slower than other R33 GTRs making 80rwhp less.
Im fitting and tuning a set of these turbos in the next 2 weeks so i will post the Dyno graphs.

[Dave_R1001]

Whats the general concensus on something like a pair of GT2560R's then?

[rich24v]

Hello people.
Wonder if you could help me.
I've been quoted Nissan part number 14445-79E00 as the gasket I need for my project. Do any of you guys run a EPC who could confirm this is a good part number, and that it would be possible to drop into a nissan dealer and order it. Also I'd like to know which vehicle it is for ?
I'd explain more of my project, but you might tell me to bugger off at this early stage. I won't bother you all much, I just need this little piece of info.

Here's hoping.......

Regards and thanks in advance

Richard.

Agreed - I would be interested in seeing a direct comparison as well. Only problem is finding two cars that have the same options/ age of cars.....
