i'm looking at buying one of these

700177-5007

gt3076R

external gate

front trim 56, .60 ar front surge slotted

.84 rear trim, .82 4 bolt rear

i have the option of the .60 or .70 front

is tthere going to be much difference?

my combination at the moment is a standard rb25det

Ive got a 6boost and plazmaman

was recently making 300rwkw on a standard exhaust manifold. 3076R.70 front. .82 rear internal gated

i

everyone is ignoring my post =[

hey mate, you're wasting your time putting a 0.7 compressor cover on this type of GT3076. The 0.6 is surge slotted and flows more than enough for this compressors peak.

0.7 will just make it more laggy, and give you headroom that you can't access and that the compressor can't reach.

Bumping this great thread with my results that are finally here.

Despite what most people advised, i ended up buying a 3071 with the genuine Garrett .82 rear

I absolutely love it; full boost (17psi) by 3600rpm and makes 280rwkw. If i did get the 3076 i still think i'd struggle to make 300 with internal gate. (I firmly did not want to run ext gate)

it was awesome. I had a 0.82 rear on it and didn't like the lag.

Get the 0.63 rear with the slightly bigger internal gate on it, there is a special one you can get. Its still garret, you've just got to ask for it.

I Was running 14psi, 16psi, 18psi, and 20psi without issues, but I recommend water meth injection for 18psi+ on this rear. It helps with the detonation.

And f**k the response was good. with the WMI, I was lighting 1st, 2nd and 3rd, and fishtailing at 100\kmph when I knocked it back to third, and not even having to dump the clutch. Just rolling on the throttle gave it a kick in the ass.

Just make sure you have a good tuner, and good support systems.

Thing is I cbf changing my setup again.. i don't think my injectors or my bank account have much more to give sadly.

If i start to hunt more response down the track, perhaps i'll go the smaller rear. Good to hear that it can be done!

Nice Ric, intake held up. :thumbsup:

That 3071 is working hard, now dump some eflex in the tank for us... :yes:

Do you have a graph?

I'm seriously considering buying the GTX3071 with .82 garrett IW rear...

After seeing the negligable difference in response betwenn the GT3076 and GTX 3076 on that subie, i really hope the GTX3071 is the same with slightly more top end and negligable difference in response.

Dreams of this turbo running Eflex :D

Does a GTX3076 spool slower compared to a Gt3076? Was the Gt3076 ball bearing?

Thinking back I should have ordered the 0.63 A/R turbine housing on my 76R ad if I can I'll probably exchange it .

As Mr Mafia showed they make pretty good torque on an RB25 and seem to have really good response for a GT30 based IW turbocharger .

    • I'm firmly on the "zero compliance is good compliance" for FUCAs. I'd be looking to solid metal joints even if the primary reason for having them is because they facilitate the twist in the arm. I have never been more happy with the way the front suspension behaves than I have since I got rid of the FUCA bushes. Even the thin little (short lived) poly bushes in the Whiteline adjustables have too much compliance for my liking. It probably won't be long before I have sphericals nearly everywhere, probably including both top and bottom arms in the rear, and I'll start complaining about the increased costs for dental work. But I will be enjoying the driving more, I'm sure.
    • Plus, you'll get great experience in bedding in pads!
    • I have offset Nismo brackets so the fact the gktechs can pivot is less important to me. I have 170mm JIC arms with bushings - but they provide no adjustment and I'm not sure whiteline eccentric bushings will fit them (I don't want to ruin the bushings currently in them to find out). Ideally I want something with bushings + adjustment; hence why I'd like to find a pair of these. Unfortunately they aren't easy to find.
    • @Vee37 How much do you really care about finding these pads again? If your pads are quiet, work well and produce minimal dust, really isn't that enough? If you are set on finding the exact pads again, I suppose I'd do something like this -  Visit your local Jax, find out what brand of pads they carry. If the Jax workshop you previously went to had the pads on the shelf, then you can almost guarantee it will be of said brand.   I'm guessing you don't have the receipt for the previous work and pads. Can you visit a Jax workshop and see if they can look up your previous job to see what pads were fitted?  Still no luck? Put your stalker hat on, find the staff that used to work at the Jax store and ask them. Talk to local workshops, try to find out where the mechanics went to. Talk to Jax workshops, maybe they relocated to another workshop. When it comes to mechanics, its a small world. You'd be surprised how easy it is to track someone down. If these ideas don't work, shit will start getting crazy very quickly.... You could find out every brand and model of pad that fits that car... and try them individually ticking each off the list if it wasn't the one you were looking for.... If you go down this path your going to want to learn how to swap pads yourself, it is very easy, takes minimal tools and space. If you have room to park the car you have room to swap the pads. Plus you have the advantage of making sure all the brake hardware goes back in so they won't squeal!
