Opinions on a 6466 w/ .84 TS on a built 2.6 with 272/272 10.2mm lift cams?

I have poured through this thread, and as such was leaning towards the 6262 or even considered the 6062 Gen2 thats just been released - but my engine builder is telling me the 6466 is 100% the go

I trust the workshop, but just want to double check other's results; dont want something that comes on at 5k or later.. id rather it come on hard at 4.2-4.5k rpm

Its concerning seeing people say a 6466 outflows a T51R

A rb30 usually adds about 500rpm response all things equal... My cams are bigger than yours, so you could possibly base it off that. I'm using a 1.0 divided housing.

I don't think it will be bad, certainly better than a T51R in response, even if it does flow more top end. Thats the beauty of new technology.

If you're worried about response though your are probably better off with a smaller turbo, unless you have a power figure you definitely want. Take into account the 6466 is a 600awkw turbo

Depends on car use, I'd be giving a 6062 a go if your stuck between the 6262 and 6466 for a decision. It should sit right in the middle in response and power :)

I try and do everything with my car from tight sprints, circuit work,1000m drags and powercruise etc. and the 6262 is right in the sweet spot of power and response. I actually turn it down 140hp for everything apart from powercruise and drags because it's more than enough. What do you want from your car?

A 6466 is going to be responsive for its size but it's getting towards drag car only power band on a 2.6L, if that's what you want then go for it but your never going to keep up with the Jones's.

What would you guys recommend for. Street drag VL, auto re401a

Forged Rb30 NEO head

270 9.2mm cams

Plenum etc etc 3k stall

Currently running gt35 .82 internal gate

22psi 422hp but out of injectors

98ron

I was looking at the 6466

6466 1.0 divided.

I make 433awkw on 22psi, 98

100kw more on e85

Should be plenty to run 9's

It's been a while but here is my Dyno sheet from build

Rb26 precision 6262 at 19 psi.

Car is running good other than its smoking from turbo.

Anybody here using restrictors? I just put a .030 restrictor and stopped smoking but not sure if I should drive it.(n1 pump)

Thanks for the quick reply guys. Haven't removed the factory restrictor. I'm running a -4an feed line and a -10 am drain line. Drain line is pretty straight down with now kinks. I also did a leak down test and compression test on the engine. Got 128 psi on all 6 cyl.(running 8:3:1 CR) and dry leak down test was 10% on al 6 but #1 13%. Not sure what other options I have

I'm getting 45psi. Pressure at 2.5-3krpms and over 60 psi from 4k up

Is that America?

because that is epic power in Australia for that boost

Lol yeah. I'm in the U.S.

Setup made

390hp@9psi

450@11psi

560@15psi

611@19psi

This is on a 2.6, 87mm pistons and Tomei type B cams, t4 .84 divided housing and limiter on 8400 Rpms but u can see dyno sheet actually was 7.8k Rpms

Hell yeah. I'm in the USA too. Here I am thinking of seeing 550 whp on pumpgas and I'm at sea level and I'm on a stroker motor. Heck I may see 650 whp on pump after seeing this !

You'll probably see 550 Australian horses if you've been looking at our graphs. More if in USA

    • 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"
    • But first....while I was there, I also swapped across the centre console box for the other style where the AV inputs don't intrude into the (very limited !) space.  Part# was 96926-4GA0A, 284H3-4GA0B, 284H3-4GA0A. (I've already swapped the top 12v socket for a USB bulkhead in this pic, it fit the hole without modification:) Comparison of the 2: Basically to do the console you need to remove the DS and PS side console trim (they slide up and back, held in by clips only) Then remove the back half of the console top trim with the cupholders, pops up, all clips again but be careful at the front as it is pretty flimsy. Then slide the shifter boot down, remove the spring clip, loose it forever somewhere in the car the pull the shift knob off. Remove the tiny plastic piece on DS near "P" and use something thin and long (most screwdrivers won't fit) to push down the interlock and put the shifter down in D for space. There is one screw at the front, then the shifter surround and ashtray lift up. There are 3 or 4 plugs underneath and it is off. Next is the rear cover of the centre console; you need to open the console lid, pop off the trim covering the lid hinge and undo the 2rd screw from the driver's side (the rest all need to come out later so you can do them all now and remove the lid) Then the rear cover unclips (6 clips), start at the top with a trim tool pulling backwards. Once it is off there are 2 screws facing rearwards to remove (need a short phillips for these) and you are done with the rear of the console. There are 4 plugs at the A/V box to unclip Then there are 2 screws at the front of the console, and 2 clips (pull up and back) and the console will come out.
