You post the most retarded shit on these forums, as soon as i see your oversized signature picture i sigh

Yeah yeah and you cant drive for shit. :yes: also I didnt say all billet wheels are heavier then the std and also they do spool slower in most cases.

Actually you said:

Billet wheels spool slower because there heavier.

So yeah, you basically said "there" heavier as an explanation of why they spool slower. Best favour you could do yourself is stop talking, at least until you've tried to understand what you're talking about.

For what its worth, here's a couple of interesting stats I've encountered in my travels:

Garrett GT3582R cast compressor wheel weight: 120.2 grams

FP GT3582R HTA billet compressor wheel weight: 93 grams

Wouldn't be surprised if the Garrett GTX compressor wheels are heavier, but they have more blades and are overall larger than their cast equivalents.

Some more stats for compressors, while we're here:

GT3076R HTA - 54.8mm in, 76.0mm exd.

GT3076R - 57.0mm in, 76.2mm exd.

GTX3076R - 58.0mm in, 76.6mm exd.

T67-25G - 60.5mm in, 78.0mm exd.

GT3582R HTA - 60.0mm in, 82.0mm exd.

GT3582R - 61.2mm in, 82.0mm exd.

I ordered that loosely on overall wheel size, and bet a mince pie that you'd find that it matches order of transient response for said turbos too.

I do understand actually, I guess ile have to copy and paste info next time hey :yes:

Should have worded it that way, you make a blanket statement and "forum heros" will tend to try and crush statements which could start a perpetuation of misinformation. It will typically be for the good of people who read through the thread in future, if the comment was ignored and left there it would turn into a "fact" and people who knew no better will be all like "Sweet I need a cast compressor so I get better response" and potentially forgo the latest greatest options. I have NFI what the billet Kandos are like, and wouldn't want to recommend them until I had even an inkling of how they performed and lasted.

hey hey hey now, those who voted labour are looking back laughing that we actually made it through the GFC quite OK. we might have done better if we were under liberal, but thats anyones guess.

Not to get in to politics anyway, just dont give him that much credit.

And Kando Billet heavier? Allow me to introduce Sir ebay himself:

http://www.ebay.com.au/itm/Turbo-Compressor-Wheel-Billet-7075-Kinugawa-Garrett-GT3076-GT3037-57-76mm-BB-/280877255518?pt=AU_Car_Parts_Accessories&hash=item416596cb5e

30% lighter than genuine cast wheel they said

Offer extra 30% airflow than stock cast wheel they said

I suddenly am very very suspicious of Kando, I wouldn't touch that with a 10ft barge pole - at least until I saw some fairly decent evidence it wasn't going to explode. 30% more power with what looks like essentially the same design, albeit milled out? Garrett "only" claim around 10% more.... I'd love to know what kind of testing they have done to make those claims, and ensure it's not going to fly apart.

It's not like a ebay seller would let the truth get in the way of a good story haha

The extra flow does come from the smaller shaft hub creating longer blades, in the photos you can actually see there is a fair difference in blade length. I don't know if there was testing done on actual flow but I would imagine the CNC machine would be able to calculate the extra volume created by the changes and maybe they did rough calculations from there... In terms of them blowing up, I'm sure once someone tries them out they will find out :)

Yeah definitely aware of the tricks - hence the reference to "milled out", trick is that same thing which is a lot of why billet turbos tend to flow and spool better is also some of the same stuff required to keep strength. Whether there has been any design consideration to ensure optimal flow where material has been removed, or structural integrity to the level required to hold together at those speeds - who knows.

Kando turbos have typically been about effectively mimicking proven design, as soon as they go about redesigning (even if it means "just" trimming the existing design) we're moving into relatively unchartered territory. Doesn't mean its not going to work, just I'd rather watch the guinea cops and see how it goes for them.

I love the illiterate use of "there" instead of "they're"

They're spelling is going to improve because their going to back to school on Wensday nights and will get some lessons than come back and post on the forum, provided the whether is ok

Oh god no. You did not just type that! :domokun:

Man, I know my typing is often full of typos and occasional poor grammar/english but i pray I get ribbed on a car forum and correct it before my boss or customer reads it and sacks me for not being able to spell better than his 10yr old :spank: Just a gentle ribbing as I do see western civilisation going down this path :)

But back on topic....is a second hand turbo an option? If so what about the Apexi RX6 turbos. You see them from time to time and they are meant to be very good things with regards to response and torque, don't quite match the T67 but give a pretty meaty power curve.

Also, have you already grabbed the R34? They are rather heavy for a rwd car and quite expensive. If budget and speed are more of a concern than styling I think a cheap R33 shell would be the way to go as they weigh about the same as an R32 (by the time you have considered gearbox/brakes weights etc but at least a full fuel load lighter then an R34 GTT)

Yep, I blame texting for my poor grammar, it auto spells so I dont have to think :woot: , but yes back on subject I was wrong about the billet wheels being heavier but I was right about a slower spool. Turbo choice would be a T67 or Twin Scroll GT3586 on E85

Check out the link above the dyno graph on this page. There's some graphs with a PTE5857. It spools between the 30 and 35 but kicks ass all the way to 7500rpm. The others don't hold boost as well and both their torque and power drop off considerably more. They hardly make power after 7000rpm, not quite ideal in a track car. I reckon it needs to be thrown into the mix seeing that.

Thanks Simon.

Yes, done deal. Always wanted an R34 and whilst this may not be a GTR it doesn't matter as I'll just refer to it as my 34 and say nothing more! Haha.

This one was basically given to me so don't worry about cost, and it's for now just something I want to build for MRA, Irace etc and not worry about a bit of argy bargy like I would do in my 32. I'm trying to make it as different as I can to my 32 so it's a totally different experience to drive, hence single turbo and rwd and anything else I can do to make it different. Why have two cars essentially the same? Same to be said for the build cost, my 32 is no expense spared (plenty wasted) but this will be budget.

It will be interesting to see what gives me more grief over time..........

Thanks for all the feedback guys, appreciate it!

Will be interesting to see what you go with, and the results - have you made a decision?

Re: The PT5857 results, they look really good... and had thought about suggesting that one, but didn't because it starts shooting in territory closer to the GT3582R in power, and obviously response. ie, capable of well eclipsing 370kw on E85.

If you are "only" going for ~370kw then the extra pull up top you are seeing in those dyno plots (which are using US 91 octane) may not really make themselves as obvious when you are using E85 and a lower boost level. I was shooting for the "torque wins races" end of the scale, and equivalent power for equivalent power the PT5857 will argueably be slower than some of the "smaller" choices. If you want to shoot for a power level past what the smaller ones can do however, the PT5857 starts becoming a wicked choice.

Threads like this are a bit tricky, because a lot of these turbos haven't been tried on RBs and I have no idea which turbo you are going to be using or what boost level you're actually going to target etc etc etc. So many variables, so "results may vary". I like where you're heading with it though, and keeping an eye out on how it all turns out. Did FullRace come back with a suggestion?

    • 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"
