The GTX3584RS will support roughly 850-880HP on a 3.0L (maximum rpm of ~7500-8000) at a PR of about 3.1-3.3 No chance of getting 1000HP out of it, not unless it can be done at a PR of 2.75 and even th

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.

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!

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.

      Installing the fuel sender O ring in R34 GTT

      By DraftySquash · Posted

      Another weekend and another project I have questions about.... I bought a fuel tank sender O ring to install on the car because I'm quite sus on what I've got now.  1. No "whooosh" sound when opening fuel cap 2. If I fill up full tank, there will be a small leak under the car and it comes from the top of the fuel tank, dripping along the side. Stops after a short while 3. Hot days = 50/50 chance to get high as a kite inside the cabin if the car was in the sun for too long This is what I bought: https://www.amayama.com/en/part/nissan/1734279900 My plan was to just replace the O ring but I've got some questions: 1. Does the whole fuel pump assembly need to come out for me to replace the O ring?         Or, could I unplug all the connectors and fuel lines at the top, take off the twisty part (17343) and put in the O ring from the top?  2. Is it a very common thing for everyone to just change the pump whenever doing this?        I see the Walbro 255 gets thrown in a lot but I've got no issues with my pump so far. When I did the tune, I asked the guy to check my fuel pressure and he said there were no issues too. But is it just a good idea to change to the 255 anyway as the old unit may have been in there for so long? The 255 seems to be a direct fit for GTT (I got no soldering iron)

      Normal speedtek issues, bin it and go cdoo# or 8hp. So many issues with these gearsets, a mate went through 3 rebuilds and multiple parts with heat, bearing and vibration issues.

      CAM COVER BILLET HALF MOON RB RUBBER REPLACEMENTS

      By Duncan · Posted

      I wouldn't go near them, they are rubber seals for a reason. Just chuck new cam cover seals, half moons and the spacers for the screws every decade or two. I add a really thin layer of silicone too and it seems to hold together OK

      CAM COVER BILLET HALF MOON RB RUBBER REPLACEMENTS

      By joshuaho96 · Posted

      AFAIK on most Toyotas that half moon is usually an aluminum piece that you seal with RTV so you just source the valve cover gasket but I kind of doubt that you'll ever save money buying an aftermarket piece in this scenario.

      If I tossed my money in a fire and filled my transmission with sand, it would end with the same result as buying from Speedtek. Actually, that's not true... My way, I wouldn't have to deal with Speedtek's dick head of a CEO for years on end and all his lies.
