Kando-TD06-RB25-dyno-chart.jpg

Swapped my rear housing to a 10cm, made 235kw on 18psi. Was expecting more, and the Stagea needs more being a big heavy car.

Mick had to put a shim in the turbosmart gate to stiffen the spring, as it didn't want to hold boost. You can see it peaks at 18-19psi and then tapers down rather quickly. Rubbish, my old tial off the skyline held boost rock solid.

Turbo didn't want to make any more power either apparently, which is pretty lame.

Specs:

Kando TD06H 10cm
Turbosmart comp gate (f**king rubish unit, never using it again!)

3 inch exhaust

return flow intercooler

high flow injectors
Haltech E11
Run in RWD
98 Octane

I guess I'll go a T67 next, or probably back to Garret. See what happens. Unless someone can suggest something good for 280-300kw? needs to be low mount though for uber stealth.

Adam I reckon its the return flow cooler. Those always cause havoc..

The turbo should make plenty more than that, especially with the H rear side. I'm assuming its a 20G compressor? 260+ should be more like it.

The fact the tuner thinks the turbo is running out of puff definitely tells me the restriction is in the intake side.

After seen Roy mentioning about the TD06H I went through all TD06H dyno readings on Trent's dyno and did comparison against the SL2 turbine. TD06H turbine appeared to be laggier without making any more power. You can try our billet SS2 comped SL2s that is a step up from the standard 20Gs, or I think a standard highflowed turbo would make more power.

depending on where the external gate is attached. won't make good results if it is welded on turbine housing, locating it to exhaust manifold would prove other wise.

Cheap return flow cooler do have heatsoaking issue and takes much longer to heat sink compare to a good branded cooler.

^^ This, if done right.

All Stao's attempts have been at 90 degrees to the flow I think, mine (Artz's) had a nicely die ground entry knife edge with a curved pipe. There is no way the exhaust flow can do a 90 degree bend while travelling at the speed of sound...

My thoughts exactly regarding what it "should" make. Interesting idea on the return flow cooler setup.

I like how the engine bay looks nearly stock (except the gate off the manifold). But if going the conventional intercooler setup to gain a extra 30-40kw then I'd be down for that.

Though pin-pointing whether it is the cooler setup holding it back, or if I just got a odd turbo or whatever, will be the tricky part.

Just don't buy a "conventional" setup the same as you sold me...what a piece of shit..i fixed it, but what a piece of shit...lol

intercooler pipes didn't line up, not enough silicon, the intecooler pipe mount that goes at top of rockers was complety wrong..lol

cheers

I'm not using a justjap kit, we made our own using a core with inlet/outlet on the one side.

But still, kinda don't want to spend any more money on it until I know for certian, this whole kando ordeal I've had ... I probably could of bought a 3076 or something with the cash wasted :(

I'll do some digging on the return flow cooler problems though while I'm at it, anyone else had problems with return flow intercoolers?

I sold you a intercooler kit? was it brand new? if so you might want to talk to Darren Spencer (as that's who I got it from) about it, he had been importing them and assured they'd be a good fit.

yep, new, ..worst china cooler kit i have ever seen, f**king pos...if you paid a workshop to fit

it would cost a f**king fortune , absolute mongoloid...not angry at you, just telling you, if you go conventional..do NOT buy another one..lol

i just put a 38mm turbodumb gate on my hypergear G3 turbo of exhaust housing, straight 90 right at the flange, in a stagea has to be close as it ends up to near to the strut tower for my liking, and i am not really sure making it a nice entry makes any difference, i would want to see the results backed to back to worry about piss farting around with it(for this car anyway) . I also woudn't be suprised

if using different brands of gates made a big difference aswell

cheers

My brothers car had the same problem low power reading cause the return flow cooler setup on his car

He went thru numerous turbo setups all came up short of what they should put out and got his cams dialed in still similar results

End up just changing the cooler to a normal cheap 3inch inlet opposite sides and bang 20kw should have done it to start

Unigroup told him to change the cooler at the start but he didn't want to butcher the battery tray as it was a 180sx they did all the usual tests pressure drop,exhaust back pressure and comp test all came up good

yep ^

I think its more so the harsh turn that the air has to do in order to flow back the way it came which causes friction to the air's particles and super heats the charge after its already been through the cooler.

You then have a nice cap on how much power you can actually make, and theres no way you can test it as pressure drops and air leaks have little to do with it. The core Adam is describing is the worst, where it basically hits a brick wall and is forced back the other way.

I know the air particles business sounds airy fairy star wars but thats actually the way it works. air gets friction against itself and gets hotter.

This is the kinda core I'm using lads. I get where your coming from Scott. I guess I need to decide whether I want the car to look stock and have average power, or put in a conventional cooler kit and gain the missing power I should have, if thats the problem.

Another thing Mick mentioned is that the turbo didn't want to make any more boost, maybe the intercooler is a restriction after all. I think I'll sort it out after Eastern creek next week.

    • Just wanted to pop in an update on my setup. The CD swap has been great, I love the mazworks housing for the overall simplicity. I ended up sealing my trans tunnel with a thin sheet of aluminum reused some of the holes on the trans tunnel, and laid some window sealing EPS foam around the edges. Works great, really quieted things down and sealed up the car.  As for the power comment. Right now I am also running about 650whp. with the way the bell housing is attached to the face of the transmission I have zero doubts it would be fine, mainly because the input shaft and main shaft bearings are seated into the bell housing adapter. This means the load is NOT on the bolts to maintain the power, rather into he casing of the bell housing; Yes the bolts are doing some work there, but with both shafts locked in zero worries.  End of the day, the Mazworks solution is the easiest and safest. no need to take your trans to a shop to get milled perfectly, it fits with minimal clearancing, and you can use all your existing clutch and flywheel.  Driving wise the CD has been great compared to the big box, I'll probably swap my final drive at some point. The serial 9 shifter is gooooood, my only qualm is how tight it is, it takes a fair bit to get use to, 5th and 6th are a bit eh/hard to find at times, but maybe I need re-adjusting, and I think my clutch master is very tired and needs a rebuild. 
    • If you are keen, have a look at my build thread. Car is for sale for the right money or straight swap for a F80 M3 LCI.
    • Welcome mate.  No point in over thinking it, buying any one of those cars you mentioned is not a smart or logical choice with the availability of many "better" (re price to performance) cars available to you.  The heart wants what the heart wants, buy whatever it leads you too.
    • Hey everyone! Im so grateful to be apart of this community and ill do my best to be apart of this. Firstly, i'm not disclosing my real name due to in real life circumstances surrounding my privacy and public image (sorry lol) Secondly, The only thing personal I am willing to share is that I'm from Sydney and a descendant of one of Sydneys largest mortgage firms. I got gifted my first ever car, a 2022 Porsche Cayenne and I love it to death. Ive been driving it for about 5 or 6 months now and honestly Im so grateful for my parents for gifting me this vehicle. However recently I've been working my ass off to afford my second car (which I need help deciding soooooo community help me out please?). Once decided, im planning to try modify it myself. Recent I've been thinking about getting a Skyline, particularly a 25GT or GT-V, yes I know overrated as hell, but I'm also considering a Chaser which I recently came to love. However my dream is to one day own a 180SX (So hard to find clean versions and im not really into importing).  Lastly before I send this off, I want to apologize if I sound tacky or pretentious. I try not to and want to genuinely learn from everyone and anyone. (Im no expert in this area) Thanks for reading!
