Kando Dynamics Turbo

[XKLABA]

Note how the 20G falls over on top end. This is from our re-worked version: SL20.5 mentioned earlier. It is made to have the same down low torque as the 20G, while holding the power band up top. Running against Kando's TD06L2-20G on a standard RB25det motor, Same response, more power with much wider power band. Nothing is changed apart from the turbocharger. Price difference is within $100 to listed kando item.

Less then $100 difference, why would you buy the Kando

Do you do this or can you do this as a bolton for the RB26 running in twin form, like the Kando do with the TD06L2S-20g ?

Have you got boost plots to go with those curves?

[Dale FZ1]

^^ I would like to see this also.

In the absence of boost plots, the 20.5G looks to be a little lazier coming on, and then in the best useful torque zone (4000-7000) it flattens by comparison to the 20G up until 5500. And then it seems able to hold torque from 6500-7200 thereby producing the bigger power number.

The 20.5G unit looks more linear (which I like) up where it's doing its thing across 4000-7000, but you've got to be able to consistently use that last 750rpm to make it worthwhile. Debateable which spec would be quicker point-to-point or around a track for a given car setup and driver of average/good ability. That aside, there is value in supporting an Australian business. For the minor cost difference customer service history might influence the final choice.

and one more set of data:

[Dale FZ1]

It does appear that the dyno graph differences are related to boost delivery, and the 20.5G making more boost over 5000rpm. Whether that's more strongly related to pumping capacity (surely the 20G is hitting its peak, if the numbers on the graphs are an indication?), or boost controller settings only the tuner will know for sure.

It's looking like a case of gain in top end at the cost of some spool and mid range. Would be interesting to drive the two back-to-back and see how they feel, rather than base it only on graphs.

The 20G can't be dismissed as obsolete.

[Roy]

If you are making 290-310rwkws (dyno differences and all) out of a 20G compressor based turbo you are getting near/to the limit of what the poor lol thing can pump, lol surely.

The 20.5G seems to be a smidgen slower to build boost but hangs in nicer up top. Boost taper suggests the 20G is at its limit..the hp and torque drop off really confirm it. Why wouldnt you take the extra hp in the final 700rpm if its given to you for $100.

But i wonder if its a compressor thing or turbine. I have always felt that the L2 wheel is a bit rubbish. My TD06 always held on way better up top compared to the L2s despite all their hype. Perhaps the 65mm turbine gives a bit more torque and helps the compressor keep the boost up. Indeed those in the Evo world hi-flowing all the billet 68-82mm compressors on Evo and STI use the 65mm and 67mm turbines...not the lil 61mm L2 version.

Accessing/using the grunt is where I see priority. It could simply be a matter of driver preference and ability. Running them back to back on the road/track would make it clear which best suits, and proves whether the bigger number on a graph equates to a faster car.

I'm not against the 20.5G, and agree its looking like a case of rob Peter/ pay Paul with the response/flow equation. You'd fully expect that the 20G boost tapering at higher rpm indicates it's running out of puff, but it might be that the quicker spool and beefier hit of mid range torque would fire that Skyline off each corner easier/faster than the 20.5 which then has a job to chase it down and hope the straight is long enough to make a pass before the next corner.

The $100 price difference is not an issue in my mind. HG does have a lot of satisfied customers with positive comments about the service, which counts for a lot.

So what do you think roy.? The 20.5g be cool on a built and pon cammed rb25? It wouldnt make it to 330kw-350kw mark though on wmi/e85. What would it make on p98 ypu think for a tune that I can use to get the most/best fuel economy for long trips. A mate just thinks I should get a efr7670 as itll give made response and probably nearly hit 380-400kw but I have no Idea im currently stripping it and painting it in the few weeks so I want to get everything organized. Another mate said ge kando to make me up a gtx3073 in 52 trim on a smaller 1" runner mx performance top mount manifold for better spool up with a 44mm gate off the housing from scotty. Iv also got to choose a new ecu as ive sold the Vi-Pec v44 I had. Was one of the first ones. Adaptronic worth a try you think or just go a link vipec or haltech?

Josh if you have a reasonable budget to play with, I'd urge you to consider a BW. It's good to examine all reasonable options/combinations but I think there's better options than what's been discussed here.

Look closely at the Airwerks range S200SX 7670, running T4 split pulse. Combine that with the small runner manifold you've mentioned and you ought to achieve extremely good response and hit the 450-480rwhp mark. That particular turbo is quite price competitive with what's been discussed here, but likely to easily outperform both for overall response:flow. No dicking around with "special" builds, and durability proven.

It is evidently a reasonably well trodden path in the US, so perhaps worth a bit of wider searching, and enquiry through Full Race. They are also quite responsive to customers.

Your biggest associated cost would be plumbing it all up with twin gates etc if you want to get the very best from it. The pictures of GTRJoey's 8375 install tells a story, but his results bear witness to the return on effort/expense.

SR22 with 7064 on 98 vs my RB20 with 20G on E85 made DOUBLE the power i had at 4,000rpm. We made the same peak power. So on a 25 it would be uber on 98 with WMI and expect it would knock on 330 and leave any Mitsu based turbo in its dust. The SR22 was running under 20psi too so there is some headspace....EFR all the way if you can

[R_34]

Any dyno sheet of that SR22 ?

I need some data to finish convincing a mate with a SR to go EFR and he's thinking in going darton sleeves, 90mm bore if he ever needs to.

It currently has a china 2871 which won't last long @26psi on his still 2L SR.

I would love bolt on borg warner twins for my GTR to replace my HKS 2530s. Anyone know if this could be possible?

Do you think the front and rear housings would be usable?

A pair of EFR6758s as boltons would be very nice

They are a very interesting looking turbo... I would love to run a pair!

Only issue I can see is they look long, and wouldn't fit. And definitely not bolt on. You'd need some pretty wild mods down there to fit them

Two chances of making them fit in factory location.

What you can use is your current front pipe. They bolt up when using the Full Race dumps.

[The Mafia]

that's awesome but crazy haha

[Dale FZ1]

That looks GOOD.

Will someone start a thread on the BW stuff and keep this one relevant to Kinugawa?

[Joshbigt62r]

I thinkthere is a BW EFR thread. Do you just mean BW AIRWERKS.?

[sama1500]

does anyone here have dyno graphs of the kando td05 18g and td05 16g on an rb20? ive been searching through and getting mixed results but not too many graphs, i'm considering getting one of these turbo's and would like to compare spool times mainly so boost/rpm/power graphs are much preffered, thanks

[patrickmm10]

Just wondering how streetable and daily frienly this turbo would be on a manual rb25/30 (only mods are ARP head and main studs and cometic HG)?
