Garrett Medium Frame Gtx Turbos

[ARTZ]

So, Phil group buy time? lol

Hmmm me thinks the GTX3076R + 6Boost manifold on E85 with nitrous would be a nice upgrade from the GT-RS......

ME thinks engine wont last long...

[PM-R33]

Quite you

[Lithium]

GTX3071R on E85.... 350rwkw? That would be something.... DO WANT

I would say it would go over 350kw, GT3076Rs have gone over that and this has more pumping ability...

[Harey]

OOOOOOOOOO dont these look good. GTX3071R for me thanks

I wonder if this will expand what they can get our of their GCG hiflows?

[MJTru]

for the 1700 dollar price, has anyone looded at ams gt750r for 1500. witch is the better turbo for spool time and max power?

One common theme I noted from the specs of these 3 GTX turbo's is that they run a slightly larger exducer than previous models, but run comparatively more inducer size....i.e. these 3 GTX turbos all have 58 trim comp wheels - up from 56 trim.

3071 model now also has a .6 comp cover - previously .5 comp cover

For some reason when I log into turbobygarrett.com I can't see the GTX series in their catalogue. And the pics hosted on this thread won't open either???

But if Honeywell have stepped up a size on the inducer then it's no wonder they have shifted their maps over to the right and claim they will support higher outputs than the previous GT models.

Was there an update to the turbine specs that they are using, or just the compressor?

turbine side remains the same from what i can tell

[N1GTR]

Come on X series for the -5's

This is awesome news, i was just about to buy a new turbo. Thankfully I have been putting it off!

Plus i could not decide whether to get a 3071 or a 3076.... Now I will get get the GTX3071R for sure

Note the compressor housing A/R's , 71R 0.60/76R 0.70/82R Port Shrouded 0.70 A/R .

Without seeing pics my guess is 71R T04E 0.60 A/R , 76R T04S 0.70 A/R Port shrouded , 82R T04S 0.70 A/R Port Shrouded .

Garrett do make a 0.70 A/R T04E housing but its a weirdly shaped casting .

AFAIK the GT40 series comp housings have not been used on Garrett's smaller frame BB turbos .

I don't believe what I have just read!

Its good for me as my rear housing has been modified. Bolt off, bolt on 460rwkw

Seriously Dave, as if 460rwkw is going to be enough for you!

[NYTSKY]

Youre probably right mate.

Nice "Bake Cam" vids

[Justa32]

Whats the deal with rebuilding these? Can u rebuild a blown gt30XX and drop the bearing cart + wheel in?

[R31Nismoid]

the cartridge comes with the wheels on it\

nothing to stop you doing it. depends on the pricing i guess

[wolverine]

The compressor wheel dimensions seem to be different so will the clearances be ok in an older comp cover?

The turbine doesn't appear to be an issue.

[GTScotT]

For those who arent sure how to plot compressor maps I have done a quick point to point on the GTX3071R.

This is for a 2.5L motor @ 90% VE

Boost shown on the map is 1.5 Bar

For interests sake I also checked the figures at 101% (to push it to its extreme), 3000rpm became 22lb and 8000 became 54lb.

All in all I would say this is an excellent turbo for the 2.5
