hahahaha my suggestion was in no way serious :) I'd hate to think what kind of distorted readings the AFM would get when placed directly in front of the turbo inlet anyway.

So does anyone make an alloy one with bov/breather return that isn't $300 ?

Does anyone make an alloy one with bov/breather return that is good? I didnt know there were any at all, at any cost.

I just made one up myself... Just get a 3" 90 deg bend and weld on a few plugs then use radiator hose to connect between original return pipe and the custom intake

Thats exactly what i did. $10 scrap exhaust bend from an exahust shop. cut the bov return and oil breather metal return pipes off (about 30mm cut off) turned them around and welded them onto the exhaust bend, then 2 small hoses (about 80mm) long to join up the now cut bov return and oil breather.

Chasers made mine because, as other people have found, the rev210 mod does have it's limits. 2 x 45 degree bends were used in the end i think, they wanted it as straight as possible.

They did say it was tricky to get it to work, which must be what all of you guys are talking about.

I have the standard airbox and standard BOV, plum-backed.

Wasn't cheap, $300+, but still let me run everything as it was and in it's most standard configuration, whilst being the straightest possible pipe.

that should all be past tense, as i no longer have the car :)

Thats the next level of complexity again as you have to connect it up to the standard airbox. I am just talking about a pod filter so it doesnt have to be as precise.

I made THIS for the same reasons as above.

All you need is some alloy pipes and a welder.

I made this one 2.5" on the turbo end and 3" on the AFM end so no need for silicone reducers (ugly)

Good to see another way of doing it!

However, for the guys with larger turbos I am sure it would be beneficial to go straight to 3" as quickly as possible from the turbo. I know its the not exactly the same but its sort of like a bellmouth if it goes straight to the largest diameter. Thats my theory anyway.

Had car retuned today after I had a few issues fixed up...I'll be providing Stao with the dyno sheet to post up first once I pick the car up, but all I can say is that I'm very happy with the figure. Considering I asked the tuner to be as conservative as he could and very safe up top, it still made stupid power. He was skeptical of the turbo since he'd never heard of them before, but was pleasantly surprised (or astounded moreso) with the power it made.

Since it was running without any boost control, boost came up to ~17psi initially and bled down to ~15.9psi. Tuner took out as much timing up top as he could before it would begin having a negative affect, and it finished up with 11.5AFR. Not sure of the rpm yet, but at 15.9psi it made 294rwkw.

Safe to say I'm stoked with this result.

Thats awesome, can't wait to see the dyno graph.

Mine's going back on the dyno on monday too! last tank of fuel before i switch to E85 :D

You're a prick. I want some ethanol action :no:

Who's tuning it for Ethanol?

Sounds good! Keen to see your boost graph so don't forget to get a print out while you are there :no:

Also try and get the runs printed in rpm if you can

Not sure mate. I'll go back to Ed on monday to get a "before" and base tune.

Then I'll tune the AFR's myself and up the timing a bit. Then bepending on how Ed goes with the before tune i might go back to him.

Otherwise i dunno

As some already seen the ceramic ball bearing high flow results. This is based on a stock Rb25det with factory head, cams and cam gears with forged bottom. Turbo did have some unexpected boost creep issues due to a newer designed waste gating system.

Tuning video footage of 4x consecutive runs. with consistent 321rwkws:

Turbo has been pulled apart, we are analyzing its bearing components and modifying its turbine wheel refer to some skeptics for faster torque gain.

Also we will be testing some cage less air craft ceramic bearings for even faster spool time.

Also for people whom's interested in sleeving stock rubber pipe with metal and hopping for great HP. Below is a dyno comparison to show you it doesn't work. and please don't waste time trying. (The drop at 6500RPMs was from operator back off per discussion earlier)

I would highly recommend going fora 4inch metal intake pipe with pod. All ATR43G3/4 units will be now built with a .70 comp housing with a 4inch inlet unless special request.

Since I got no idea if Stao is gonna chuck these up or not, here's the dyno charts from my tune this arvo. I don't get a torque chart tho :ermm:

One shows power+boost, one shows power+AFR. They've been overlayed onto the graph from my first tune when I was having boost issues. The RED line is from today (though I dare say that will be obvious lol)

Big thanks again to Stao and his great work, another happy customer here :)

Thanks for uploading. I was about to re-size them first. Unfortunately above turbo had some shipping damaged to the actuator lever which caused it not been able to shut in the earlier run. Great to see thing's back in working order. Hopping to see more power at 20psi :ermm:

    • 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"
