the 20g still rocks my world everytime I mash the go pedal..so much fun....:D

That said ,Hypergear has moved mountains since I built mine and bang for buck its a winner for any stock manifold application..

if you insist on 20g get a billet wheel and it should go close to meeting your goals...

And Mick makes a point...my 700$ turbo doubled in cost by the time it was installed while his GTX was a Bolton in comparison for much the same money and less headaches

I still love it tho. ;)

What would you do IF you had your time over again, if you know what you did now?

Tdo6 with billet wheel...I love my car. ... :P

and on paper the only thing that beats its midrange pull is HGs "new" hiflows. So to save all the headf**ks with custom pipework I would get a HG high flow...they are making fantastic power now and reliable as any other turbo on the market .....If your tuner says they are no good ,maybe you need another tuner...

In OPs case I think a GTX or a HG equivalent would be perfect for his needs ...leave the 20g for top mount setups

Before Artz came to me with his external gate ideas the 20G power output was only speculative. I don't think anyone had pushed one to 300wkw on a Skyline. I seem to remember it hitting 280kw on petrol, so there is either a restriction, or much more in his setup as I would usually expect 40-50kw from ethanol. Trent never pushed the tune hard as he was planning to track it.

The response was amazing for the power output. As he mentioned, a billet wheel would only help with flow due to the smaller hub and lighter compressor.

Only one I knew of was Dr Drift pushed 300kws on pulp at 22psi...with e85 im.getting same power on 17-18psi...I hit 312 @ 21psi, and I think Dori hit 308 @ 20psi...its definitely hitting a wall there though that I am pretty sure is compressor

The GTX value is honestly out the window now, I was the last one to nab a deal off them and that was without turbine housing.

Bear in mind a GT30 IWG housing is over $500 and the required dump is also not a bolt bolt, so all in all the current HG highflow SMASHES competition for bang for buck. Like FFS it costs $880 and bolts back on exactly where the stock one came off. Cannot be beat!

BUT, I don't think the said highflow will do what OP is asking..

I think if ill be maxing the td06 ill go hypergear a internal gated atr43ss2. It will put another month or two on my build but if it gets me to my goal I'm happy. Does anyone know how a hg atr43ss2 int gate would fair against a ext gate td06 10cm with billet wheel in regards to response?

Response wise there are a few hundred RPM in it. Check page 1 of the hypergear thread for links to testing, IIRC he tested the TD06SL2 turbine with his SS2 compressor back to back. The TD06SL2-SS2 combo was more responsive than a normal SS2 but made less power. It also is not compatible with an IWG housing (of HG's).

The SS2 is honestly a very good choice, I have seen a couple of locally tuned cars which run them (tuned by different tuners) and the results were on par with my expectations. Both cars had above 270kw on 98 and were mostly 'bolt on' packages, meaning I believe with better cooler pipes etc I believe they could have done better.

And yeah, don't tell your tuner what it is. Tell him its a 3076R LOL

My tuner is a pretty popular one here in Adelaide (not gona name names) but he was not keen on the hypergears a for some reason. I just don't want them to use it as an excuse if something isn't 100% on the dyno for them to be like 'oh we told you hg wasn't the best' - even if its not the turbo. If you know what I mean.

Haha ill say its a hg turbo (Honeywell garrett) ;)

LOL @ honeywell garrett.

Don't worry, I wen't to one of the better tuners in NSW and was told similar. Though I know of other issues in my setup and even the way it was tuned that were totally overlooked. They probably felt it was a waste of time without a fancy pants turbo.

That being said though, I was only 20kw short of what I felt was the best I could get, and my outcome was actually pretty damn good. Even when the tuner drove the car he was impressed, so he sort of ate his words lol

LOL Dave, IIRC you had a cropped GT30 with an old T04S wheel on it right?

Yeah a lot of hate on HG turbos.. I think its because when he first started doing business he was using much older tech stuff.. Things have changed now though and his products are great. My car really hauled ass with the SS1PU, if I wasn't chasing the big 300 I would have never changed it.

I think some of the earlier HG turbos didn't perform that flash from a lot of what I saw, the newer stuff while I am not convinced are as all conquering as there is some implication by enthusiasts - they ARE very good, if not the best bang for buck in terms of simplicity and balance of response and power. The customer support appears to be very good too, so if I lived in Australia and was doing a fresh internally gated bolt on setup I'd seriously consider going one.

If someone said they don't want one however, I wouldn't try and ram them down someone's throat - much the same as where people have asked about which Hypergear turbo to go for I haven't come in and told them to get which of my preferences I would go for.

I remember that POS Dave.

But it's BB core, must be magically better. :P

I believe it probably was a good bolton Hi-flow option....in 2004...it should never have been tagged a 3071 though because not one part of it was...well except maybe the core...but a core is only as good as the wheels bolted to it...

    • 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.
