Kkr560 Or Atr43G3

[luvpsi]

got amate here at work that beleives a kkr560 would be alot better than a hypergear atr43 G3. i have tried to explain to him the quality of the kkr560 and the problems everyone has had with them. what your opinions so we can stop this debate.

ps this is a debate of the turbos on a rb25det

[paulr33]

define better?

build quality?

warranty support? ease of installation? transistent throttle response? wide open throttle response? resistance to surge? corrected airflow vs pressure ratio? options of bearing and wheel variants?

do you see the issue? so many variants, options, and it's open to interpretation

or are you comparing for a simple flat out which makes more rwkw at 20psi ?

i reckon both are ordinary turbochargers and there are a lot better units out there, but if i had to put money on one of them i would put $5 on the KKR over the atr43

One of the shop guys on here reckons he has a pile of low km stuffed KKR's at the back door of the workshop all ready for the recycle bin only they wouldn't take 'em cos the metal was so poor!!!!

atr43 is alot better overall then the KKR turbos in my opinion. As seen in the hypergear thread there are several results and people that go with it are very happy as if on a budget you cant beat it. On the other hand all you hear about people using KKR is poor performance and having issues with them. Also youll get alot more support with a hypergear turbo as stao is more than happy to help hes customers.

the prob is hes in melbourne - what about us Sydney guys, the crappy KKR or GCG hiflow??

Once again gcg hiflow have been reputable and have given good results so no way I would choose kkr over it.

If it's KKR, does it matter where you are? You'll still have to get it taken off and sent somewhere. Stao has a quick turnaround with warranty issues, and will be VERY helpful with troubleshooting and any assistance he can give you....get that from another manufacturer (other than GCG, I'm sure they're just as good)

Power vs Response vs Torque vs Overall cost vs Technology vs Customer support. Its obviouse.

Even hypergear's stockie high flow's pumping better results.

thanks guys this helps me prove my piont haha im getting the atr43G3 from stao in the next few months for all these very reasons but he reckons the KKR is better i say bulls***

[joeyjoejoejuniorshabadoo]

gcg highflow... but for an RB25 it's an HKS 2835 pro S hands down

I've got a KKR560 in my 33. Friend has a 34 with stock turbo, both have exhausts, powerfc's, front mounts etc... I can't believe how much more responsive his car is. Mines got more power, but it's much less driveable on the street
