First of all - what's ".73"? Is it a reference to HKS housing or something?

Second - thought are that we should wait for real-world results. As of now this turbo does not seem to justify the price difference between it and conventional 3071. On the other hand price difference is not that big, 1392 USD for GTX3071 + housing that you can buy everywhere vs. 1448 USD for GT3071 [data taken from ATPTurbo site].

Personally I think (at this stage I have no real world data, so I can only assume) GTX3071 is the best of all medium-frame GTX turbos currently available and is not worse than GT3076. E.g. compressor requires less revs to reach similar airflow to 76mm GT compressor , and in general seems to spend shaft power more efficiently. The biggest concern of course is that GT3076 and RB25 combo is tried and proven many times, as is GT3071, whereas GTX turbos have yet to prove themselves.

Are you sure? I'm not questioning your experience with GT3076, but some results I've seen for 3071's so far, particularly with .63 housings, look awesome in that they have factory-like boost threshold with 1.5 or more times power and make more torque everywhere, which I think is the key to a nice and fun street setup The same definitely can not be said about GT3076.

.73 is the exhaust housing. It's a custom housing AVO can do.

I'm starting to think BW intentionally uglied up their turbos to scare off fanboys.

It just looks untidy...

Possible fitment issues to. The wastegate actuator is hanging in the breeze a bit.

Needs a billet blow off valve cover too :ph34r:

Who gives a toss how it looks if it meets the performace criteria. I hope they wax garretts arse to the point where garrett actually starts doing some real r&d and giving customers something better than 3rd rate service and dated designs.

  • Nope 1

Well, just like GTX Garretts, EFRs still have to prove they are as good as BW advertises them to be.

I wodner if 7670 can be bolted to the factory RB25 manifold. Good prices though - GTX3076 costs 1400 + IW housing 350 bucks , so it's 1750. EFR7670 can be bought for ~1850-1900 with 0.83 T3 flanged hsg, and this price includes boost control solenoid and antisurge valve. :thumbsup:

Bit it really should have T4 twinscroll IW housing, so 1950 for turbo + 1000 for suitable manifold. I need to allocate some money on this...

I think it's great. Stops all the ricers from buying them (ppl who generally don't have the proper supporting mods and give bad names for turbos by posting dyno graphs). I know ppl who refuse to consider one due to the looks of the turbo. Silly people!

Yet those people will happily what a "nice" looking turbo on the side of an RB25 with badly scractched cam covers with no coil cover and wires running everywhere.

GTS-R style low mount manifold looks better than any turbo anyway

Same, hence the comment. Though Noel took offence :)

Unless something even better comes out i will almost certainly be getting an EFR turbo next. Thinking about a high revving rb20 32gtst with a 7470 for some stupid reason these days....low mount of course to hide the elephant man looks of the comp cover

There's an EFR thread with some results in it scott

There should be results in the next day or so of an STI which first had a .82a/r GT3076R, then replaced it with a .82a/r GTX3076R, and now afaik has a .83 EFR7670 going on it :)

Should be VERY interesting to compare!

Alot of good info on nasioc forums already.

Any more real world results on these turbos?

+1 for in particular on a rb25 with a 3076 compared to a gtx3076 really need to see if there are benifets after talking about them for a while.

    • Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!
    • To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules
    • So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket
    • As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year. 
    • I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
