Hi all,

Just curious as to know what people have actually experienced with the KKR turbos that HPI are advertising on behalf of Otomoto? I have read somewhere that Otomoto is run by Ben Ellis the editor of HPI so they may be a bit biased towards the outcome, if this info is true. Either way i like their price of around $900 new so i thought id throw it out there to see what people may know.

Basically i want to know as i may need to replace the trubo in my car (R32 Gts-t) as i think it blew up on me yesterday. Cars blowing some black smoke and runs like an absolute dog on boost. Splutters and stalls, wont hold boost and idles badly.

Anyway if i do need a replacement i was thinking of buying new instead of the usual second hand R32 or R33 turbos, but without going over the top and buying a turbo that would require other replacemnt parts such as fuel pump etc. Cant afford to do all that just yet!!

Anyway any help would be appreicated,

Cheers

Laine

Ive never used these turbos but the testing they did on them in HPI netted them over 250rwkw on their RB24 (And it also took quite a bit of mucking around to make it fit) So you would need new fuel pump ect..For ease of fitting and just having a nice mild upgrade I would choose an RB25 turbo

Sounds like a boost leak of some sort. check your intercooler piping before buying a new turbo.

Yeh im about to go and check all the pipes and make sure they are tight enough. General inspection didnt find anything though.

Just checked the pipes and found the culprit. Stupid hose clamp was loose and the rubber sleeve connecting the pipes needed to be moved to make the pipes sit better and let the clamp actually clamp!

Still interested in the KKR turbos though cause my turbo is on its way out. (Overboosted in Japan before getting it here)

Cheers

hear is something they sent me when i emailed them

Hello Scott,

The KKR-480 is $899. We also have a dump pipe available to suit the RB25 for $149 (suits standard or aftermarket front pipes).

To fit it on an RB25 you need to rotate the compressor housing and actuator to point the right way. The actuator rod also needs to be bent and adjusted to suit, while the compressor housing needs around 2mm ground off at one point, where it is too close to the exhaust manifold. You will also need a different bolt for the oil feed and a 2.75-inch V-band clamp. We have a mobile mechanic in Sydney who does the complete installation for $520 including the clamp.

We recently fitted the KKR-480 to an RB24, which made 256kW at the wheels on 1.35bar boost.

Here are some more specifications:

KKR480

T3 twin-port type flange (will suit normal T3 flange also)

Oil-cooled, large turbine housing (around 1.1)

Approx 480hp

Compressor side (similar sizing to smallest HKS GT3037)

Compressor inlet pipe 70mm

Compressor outlet pipe 50mm

Compressor wheel inner diameter 53mm

Compressor wheel outer diameter 76.5mm

12 blades, six 22mm high, six 16mm high

Turbine side

25mm flap-type internal wastegate

71/79mm V-band flange (inner outlet diameter 63.5mm)

Turbine wheel inner diameter 56mm (similar to HKS 2835R)

Turbine wheel outer diameter 73mm (similar to HKS T04R)

10 blades, 28.5mm high at tips

but it does sound good im thinking of gettinf one of these

they have a years warenty so thats a good start

you'll find, just like garrett when they have a "warranty" on thier turbos... that its almost impossible to get one replaced under warranty.

i tried with my GT30 when it died due to a faulty cartridge and a bearing letting go. Garrett just told me it was oil starvation and would replace it.

Funny how the new GT30 ran for 8 months after that with no problems <_<

MADE IN CHINA....................................................

BUY A GARRETT AND SAVE YOUR POCKET IN THE LONG RUN..

AND THEY ARE f**kEN LAGGY!

Every thing I have heard about them indicates that they are quite responsive!

no one has a pic of one installed..... coz looking at the HPi install pics ...i couldnt quite see how the internal gate goes back into the exhaust?

coz they say they used the dump pipe they have to suit on the install.

Yeh ive been hearing a bit of both in regards to the response of them. I have heard they can be a bit laggy but as yet no one can actualy confirm. Some people have said they go alright so i guess anyone out there who has ACTUALLY seen one installed and seen how it goes, help us!!

Cheers for the info scott, i think most of that came through in the latet HPI too so im interested to see the final results of that install after its been tuned.

Regards

I was pretty interested in these turbos as well, saw that article in HPI. $900 seems to be pretty good to me if it's a winner. From memory they had to make some slight modifications to the wastegate; they had to bend/shift it on an angle, and they also had to file off a bit of the outside. Will wait and see.

"I eated the purple berries.... they taste like burning!"

Yeh they are laggy.. the internal wastegate gasses muffle the rear wheel and come out of a 2.25" exhaust which is just as big as the rear wheel gasses, then what about the wastegate gasses????

hence......... LAG. BIG CRAP. LAG SHIT TURBOS MADE IN CHINA

they cost 140$USD to import straight from chinese manufactorer.

CRAP!

and how big do you think your average int gated turbo's turbine housing outlet is?

:D;)

Do you even know what your talking about?

Certainly doesnt seem like it from any of your posts which have nothing thats actually factual

Can anyone say CHINA?

Oh also..

THERE IS NO DUMP FOR THE Wastegate flap like Garret and EVERY OTHHER BLOODY TURBO.

These are the specs of the KKR 480 from the manufactorer :)

    • Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!
    • To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules
    • So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket
    • As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year. 
    • I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
