Trust 517z Vs Hks Gt-ss Vs Garrett 2860-7's

[Johnny]

My statement was not stupid at all...its based on facts and actual 'back to back' testing on the same car, dyno, driver and racetrack.

Quite often im asked how i get such good results...simple...i now only use HKS turbo's. Currently using the following on our cars HKS2510's (street) HKS T04Z (circuit) HKS T51R SPL BB (drag) and have used in the past HKS 2530's and HKS GT-RS's. All turbo's have performed with better results from any of the 'equivalent' items from other manufacturers.

+1 as garrett and HKS are similar; in business practice a garrett turbo cannot outperform a similar HKS version turbo. Would be stupid if you paid more for the exact same product, just with a logo. HKS have altered geometry over the g items.

But as most of our cars are streeters, im sticking to garrett especially after reading a thread from a bloke who has a warranty repair from HKS which went sour in contrast to places like gcg etc who can fix em pretty easily right here.

BTW i think trust turbos now have a service centre here in the AU, am i right?

T51R SPL BB HA!!! you mean the one you have on your drag car that u cant get off the line because it has been high flowed and is super laggy??? That does not count as HKS, it has been modified

i would agree that 2530's and GTRS's are great perfomers...

2510's are not that great, laggy for the little power they make

i would love to see a direct comparison Garrett vs HKS T04Z

here are some other HKS turbos that "always outperform Garrett and Trust....always."

HKS 2540

HKS 2540R

HKS 2535

HKS T51RKAI BB

HKS T04R

HKS make some great turbos and some shockers!

I believe that this is a gross over simplification. Garrett have been in the business of turbines and gas cooling since the 1930's. This is their core business and it absurd to argue that Garrett cannot produce a better product than HKS.

Take for example the 2860R-5. These were released much later than the HKS 2530 units which on paper have the same size turbine and compressor wheels. What IS different is the geometry of the wheels (and probably the housings also?).

I for one, firmly believe that the Garrett product in this case is superior to the HKS product. My car reads like an HKS catalogue, however I chose Garrett units here on the advice of many track oriented GT-R users. I stand by my choice for these turbos being better than the HKS units in this application.

You can add HKS 2835's to that list as well.

Dirt Garage, if HKS turbos always outperform Garrett (a turbo manufacturing company) what do they know that Garrett don't? To think HKS source turbos from Garrett and then modify them to improve performance is naive at best. The only reason you should purchase a HKS turbo, is in a kit, so everything bolts on for your application.

HKS turbos used to be unique when they had deals with Garrett for exclusivity of certain turbo types (ie. 2530 size). Now that Garrett offer almost every turbo in their range to the public, HKS turbos are nothing more than wank-factor for fan boys.

2835 as a single on my old RB25 was a great turbo... but 2 of them are far too big for 2.6L (maybe okay for drag)

I just added my dyno sheet for the T517z to this thread... last post http://www.skylinesaustralia.com/forums/Rb...47#entry4714047

360rwkw @ 20psi

not bad for a couple of truck turbos hehe but I would imagine a similar size BB turbo setup from garret would spool sooner and be more responsive

We took a Garrett T04Z off the circuit car and fitted the HKS item...chalk and cheese. The HKS item was tuned by Mark Jacobsen who has had extensive experience with the Garrett T04Z and could not believe the difference the HKS item provides. This was the first time he has tuned a HKS T04Z and was very impressed. Yeah some of the older generation HKS turbo's you mentioned were poor for their application but not dud turbo's....id take the HKS T51R KAI BB off the list...i saw one crack 750RWHP at a dyno comp in qld...i was gobsmacked.

Dont bag a product unless you have 1st hand experience with it. Not just the fact that you dont like it because you can't afford it. (that was not directed at anybody in particular)...its like the old saying "if you want to find out how bad something is...ask someone who doesn't have one" Its like chicks who bitch about girls who get their tits done...they only bitch because they are jealous that theirs are inferior.

So is that twin scroll vs non twin scroll and so on?

Other wise its most certainly chalk and cheese because they are not the same

Hi mate no chat on rb26 turbo upgrade thread so i just answer you here:) my rev limit is 7800. my car make 280kw on 128kmh yours 230-240. i think because i got a 256 camshaft thats why the the midrange is stronger, and peak power is not thats good.

[SimonR32]

was the garrett T04Z you took off a 0.84 twin scroll rear?!? did mark tune the car with the garrett turbo or was it maybe the tune that turned the chalk into cheese???

who is bagging a product they dont have experience with?!? i've had first hand experience many of those HKS turbos

brockas and gav have both had hks low mounts on their cars... and both are now using garretts haha

I'll trade you the peak power to have 280kw @ 128km/h... that's great response for those turbos... back on topic OP should have a look at your charts before he decides... benefits of plain bearing turbos are reliability, less plumbing and cheap rebuilds;)

haha - true statement there paul...my ex had her tits 'modified' & fark it went to her head

anyways, ive gone with garrett -10's & ive had hks gtrs & gtss turbines, if there is a difference i will know about it over the next few days

lol...

-5's and 2530's are different enough to make the 2530's perform far better infact on average the GT-SS perform better than the -5's.

-7's aren't the same as GT-SS either.

I had a quick look over some of the results (about 10 to 12 of each type except for the GT-SS , they seem to only just start to be flavour of the month) and did some totals of cars that are similar, standard capacity rb26's on pump fuel. I didn't include some of the hardcore 2530 setups like dirtgarage's to make it a little easy on the -5's.

The average for the 2530's is; 388rwkw

The average for the GT-SS is; 335.4 rwkw

The average power made by the -5's is; 313rwkw

Of the same data the best power of the -5's was 388rwkw

Best of the 2530's was ; 451rwkw (have an examples of a few a fair whack higher again but, left those out).

Best of the GT-SS was 364rwkw

going purely of budget un-opened/ non-built motors maybe with just some drop in cams it looks like this;

-5's average ; 298rwkw

2530's average ; 358rwkw

GT-SS average ; 332rwkw

-5's aren't bad but, then again they aren't HKS either.

these numbers don't include my results to make it a bit fairer for the Garrett's

I would have never achieved the results with my car if i was using the cheap generic Garrett items.

I might be out of date, but didn't the Hi-Octane guys take your "low mount record" with a pair of lower specced generic Garretts?

ohh...c'mon...they will be the 1st to admit they were not off the shelf jobbies. Their MPH should tell you that.

and have a featherweight car, better gearbox, better driver etc....and they use 4th gear...lol

your post was smart and cheeky though...full marks for that.

the research rev210 did was a better example though...sorry.

Problem is different dynos, different amounts of modifications and boost etc for different setups make it harder to compare apples with apples. People who have paid for the more expensive items usually would have more to spend on getting EVERYTHING up to spec and as such squeezing the best out of them. This is an interesting entry in a NZ tuners blog:

interesting topic garrett v's hks...if u look at rips racing in nz they use garrett hair driers on their dirty thirty's

im happy with my garrett -10's

Ill keep using the HKS items.

[Marko R1]

i would too if i had them

[Swiper the Fox]

the real reason i use them is because im a rich fan boi brand whore...lol
