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

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.

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)

'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.

Where you that suprised?

I mean really.

    • Yeh I think i'll message an old contact i had for ages that manages his own tyre shop now.. n tell him what i want n work with him before ordering..  Got this 17x9 +30 Driftteks on 245/45/17 PSR Drag Radials on the rear.. They fit well - for your reference in future - Rear guards  have been lipped in & minimal to non flaring of the rear Gaurds.    
    • If only it were that easy! I also needed to remove seats, shocks, brake calipers, send my car through a fence, and use measuring and ended up guessing because I didn't remove seats, shocks and brake calipers. It can be hard sometimes Can be a little more complex than 'just measure' if you want to truly measure the entire wheel through all of it's suspension travel. But if you aren't going for every last mm then yeah, you can check the space you currently have and guesstimate.
    • If you own a car, and it has wheels on it, and you know the offset of those wheels, and you have a measuring device, you have everything you need to work out if other wheels will fit.
    • Will this fit? but they are staggered set - RAYS 57DR SEMI GLOSS BLACK 18x8.5 +37 | 18x9.5 +38 5-114.3 STAGGERED SET   or If no go could just get a set 4's wheels of 18x8.5 +37 5-114.3 - would i run 8.5's 235s up front n 245's at the back if I do?   Thanks.        
    • Put a clamp on your return line. I have a feeling it's sucking air, and introducing bubbles to your fuel. With a lot of fuel, less problematic. I'd honestly be redoing all the lines in the tank and clamps on everything.   Also, you've given two different answers to the same question: Asked if being followed by the police you could get down to use the whole tank, you said yes you could, so long as you keep off boost. However, you then followed this up that free revving, it would also cause the issues. I'm doubting free revving is enough to make any noticeable boost on what is likely a decent sized turbo.   So now I have to ask, can you actually drive it lightly and use all the fuel, or does it break up even free revving? Also, have you put a fuel pressure gauge on it? Can you hear the pump change noise at all when you're having this issue?
