How ever I would expect Hypergear's units to out perform Kando units since their project is soley based in Rb25det and they have a test car. Looking forward to see some results.

Kando T67-25g 10cm is a direct copy of a Greddy T67-25g 10cm which was designed in Japan by a massive company with huge experience for 2.5L applications so I would say that point is null and void, if not a little naive.

Saying that, I have owned both a Kando turbo and a Hypergear turbo. Both are great turbos, good value for money and would (and do) recommend either to anyone who suits their application.

I really find Hypergears sevice fantastic!! seriously i have even rang him at 7 at night with questions and he still is polite :) And also seriously i would of thought that keeping a name like that in Australia would be much better than someone complaining over a few $$ but is more up front but less in the long run once u got the car complete.

To buy and fit one of those turbos you be looking to spend $900 delivered. Then another $800 on a decent manifold, $300 on external gate, $300 making dump and screamer pipes, $200 on water/oil lines and fittings, $100 on gaskets, $100 on intake pipe. By that time you've already spent $2700 plus 10 hours of labor, 1000% defect rate.

For $1850 I can get a ATR43ss2, bolt on, all it cost me is 3 hours labor, at 320rwkws It will out perform that $2700 setup.

Obviously it cost more $$ if the turbo is more involving to make, but price for value based on the final out come is still very cheap.

I have said across many threads that a Hypergear unit will save the majority of entry level modifiers an all out packet. I know they are excellent value, and I know they work well.

If you read back my previous posts in this thread, I do not have an RB motor and do not need the specially designed RB outlet flange, my comments on price are based on a generic unit supplied by Hypergear and not the specific items made for skylines. If I still punted an RB then I would happily own a hypergear turbo at the said $1450 for an SS-1.

Stao, $1200 is a good price and I will keep it in mind, Thanks.

Hi stao a while last year you built a highflow turbo for a friend of mine (pu flow) for a R34 GTT as i did all the installation i was sure it was fine... its recently being worked on at DR DRIFT (installing injectors rail and FPR) but a massive leak was discovered.... now the leak is coming from the comp housing o ring.... i was just curious since the building of the turbo was done by you are you able to fix this problem free of charge because its a build fault?

please pm me asap!

Happy to have a look at it, bring pass when ready. Generally you won't get any oil passing through the shaft collar on the cold side unless bearing housing is flooded. I would be checking the drain side.

He mentioned it was a leak, but not specific to an oil leak.

I assume an airleak was discovered which is why the compressor housing o-ring is being blamed. If the comp housing has not been rotated since build I would consider this a fault.

If the comp housing has been rotated even once since, I would not offer any warranty on the product. Its a 30c part anyway, personally I wouldnt bother returning it to supplier.

Some minor updates:

Suffering from major set back as my R33 had its 4th engine failure. Been told cyc 3 is down in compression and filled with oil. Likely is from that dyno run which the AFM plug vibrated it self out, it made a very bad detonation and the engine had with a little rattle since. Time to rebuild again will updated with photos

Also I've had a small batch of SS-1 castings produced, and by making them in quantity I've saved in average of $200 per unit in materials and labor so they are now $1450 inc GST, high pressure actuator and braided oil line. That is a perfect upgrade for any one who’s chasing 250rwkws in factory response with plenty of usable power band.

Hope you can get the test car sorted soon I look foward to seeing some pics of the repair/rebuild shortly!

Also good to hear you are cutting costs with batches of turbo's being made im sure it will help people out with better turbos for cheaper prices :)

Further updates:

This is a fully overhual and high flow service for people with Ford XR6 or any Generic GT3582 turbocharger. Including:

Brand new CHRA assembly using machined alloy comp wheel with larger blades. Fully machined .70 comp housing and high pressure actuator.

Beefed up turbine to bearing housing adaption area. Pretty much all of them are cracked.

Ported wastegate and larger wastegate disc

The estimate power out put after high flowing is about 680HP, Standard is about 560HP due to limitation from .50 comp housing.

Some update:

Have had the engine pulled apart last weekend to find out of what appears like my mechanic didn't secure the gadget pin's retainer probably during the first rebuild, the pin slide out rubbing the block.

Leaving a very damaged bore.

Ethics its a funny thing, this is a licensed mechanic that I've used for the past 4 years, forwarded many jobs to and pretty close mate with. After diagnoses eliminating faults from hydraulic lifters, I was under the impression that I've got a broken piston from earlier air flow meter incident, so I naturally forward him with this job, how ever he stopped responding to my phone calls ever since.

Any way it’s not looking bad for the up coming engine. Getting it done at a proper engine building workshop. Every thing will still be build back into standard specifications for further Rb25det turbocharger evaluation purpose.

and this is why I trust second hand motors over rebuilt motors even from proper experienced builders. Even when people are spending upwards of $10k you see things like this happen

Hypergear's engine building mate. Obviously doesn't want to take the rap for doing a half assed job on the engine. When it comes down to it, a lot of people will choose money over friendship.

I gave that block to reflex (local engine building workshop). I'm looking for another block at moment but they said they might be able to sleeve it. So I will wait and see.

Also I've had a second hand rb25det earlier. Lucky I stripped it for a quick check up and found 1 broken ring land in piston 4. So I would prefer to rebuild, but once again not really worth it when job's not done properly.

    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
