When I hear about people say they have a GT30R, which model are they generally speaking of? Garrett doesn't have a contact number that I know of. A Garrett .pdf file I downloaded first lists the GT3071R, then the GT30R separately. Nothing else.

On their website there's this chart:

http://www.turbobygarrett.com/...t.htm

...which only lists several models of the GT3071R, GT3076R, and a single GT3082R

Yet, I've also "heard" about the GT3030R, GT3037R, GT3040R, etc. I know the GT3037R is usually associated with HKS, but I read somewhere that this turbo in Garrett's line is now called the GT3076R, and another source told me the GT3037R is now the GT3071R. The GT3040R is supposed to be a GT30R turbine wheel with the GT35R compressor wheel. Is this turbo actually sold as is by Garrett, or just built using their parts?

What I'm trying to find out is what are the official turbos in Garrett's GT30R line. Do they have new model numbers for old turbos?

I need one that will fit an Inline Pro T3 manifold in place of my SC44. I like the 4" ported inlet shroud, and need a 2" compressor outlet with a 5 Bolt exhaust housing. Is this an option with all of them?

I dont think you can get the compressor housing with a 4" inlet and 2" outlet. It's going to either be a 3" in, 2" out, or 4" in, 2.5" out. Those are the sizes for the E and S housings, unless the GT35R has something different. But like I said I'm not 100% positive, so we'll wait for other people to reply. Oh yah and as far as the different turbo models go, the 3rd and 4th character (ie 35 in GT35R) is related to the turbine side. The 5th and 6th character is the diameter of the compressor inducer in mm. All of that is explained in detail on the turbobygarrett.com site.

 

BUMP!!

For a really good question. i am also in the same boat as the original poster.

i might answer this question at least 5 times an hour
but, its a good one, and i can see how it can be somewhat confusing.

to put it simple:
GT3071R
-smallest of the GT30R series
-71mm exducer compressor wheel
-available in two different turbine wheels
-also available in two different compressor housings
--4" in / 2" out
--3" in / 2" out
-T2 .64 a/r and .86 a/r turbine housing
or
-T3 .63 a/r and .82 a/r

GT3076R aka: GT3037R
-76mm exducer compressor
-4" in(ported shroud)/ 2" out
- T3 .63 a/r, .82 a/r and 1.06 a/r (lmtd.)
- GT and T31 turbine housing available

GT3040R
-GT35R 56trim 61mm(inducer) compressor
-GT30R 84 trim turbine wheel
-T3 .63 a/r, .82 a/r and 1.06 a/r (lmtd.)
-GT and T31 turbine housing available

hope this helps to clear things up for you.

 

does the GT3076R come in a non-ball bearing configuration?

no.
R is actually Garrett's BB designation.

 

i know...that's why i asked if it came in NON-ball bearing..............

Thanks!!! Can you give a HP rating or lbs a minute for te configurations?

 

Thanks PhoenixTurbo! That clears up most of the questions. I still don't understand why Garrett doesn't list the GT3040R. Not that it matters, because I'm hoping the GT3076R will fit.

 

which one is the 4in inlet and 2.5in. outlet?

 

Can someone give the hp ratings for each one?

Also what about just the straight gt30r that I see? What are the specs on that one?

 

specs for the GT30R can be found @

pm'd!

 

Not that this really matters...but the ported shroud housing sounds super mean on the 30R!

 

Actually . . . there's a bit more to this. As an authorized Garrett Performance Distributor, we have some other information you might find useful. There are 8 different cartridges (CHRA’s) available for the GT3076R. We’ve found these are the most popular:

GT3076R (with the -12 catridge) - 520-hp
Available with the "E" (3" inlet/2" outlet) or slightly smaller "B" compressor cover
in either a T25, T3 (4-bolt discharge .36 up to 1.06 A/R), T3 (5-bolt discharge .48 or .63 A/R) or Mitsubishi (.48 or .63 A/R exhaust housing)

GT3076R (with the -15 catridge) - 550-hp
Available with the "S" (4' inlet/2.5" outlet), "E" (3" inlet/2" outlet) or slightly smaller "B" compressor cover in either a T25, T3 (4-bolt discharge .36 up to 1.06 A/R), T3 (5-bolt discharge .48 or .63 A/R) or Mitsubishi (.48 or .63 A/R exhaust housing)
GT3076R (with the -13 catridge) - 600-hp
Available with the "S" (4" inlet/2.5" outlet), "E" (3" inlet/2" outlet) or slightly smaller "B" compressor cover in either a T25, T3 (4-bolt discharge .36 up to 1.06 A/R), T3 (5-bolt discharge .48 or .63 A/R) or Mitsubishi (.48 or .63 A/R exhaust housing)

The GT3071R and even the GT2871R are available in similar configurations. Just remember that some of these may be more suitable for your specific application than others. That's where Garrett Performance Distributors like us come in.

Also remember to never, never run the water cooled center section on Garrett ball bearing turbos such as these dry as this will void any warranty.

If we can answer any questions about this or any other Garrett product, feel free to call us at (219) 996-7832.

Rod, wouldn't several of those be considered more of a Precision version and not a Garrett turbo? I mean, I don't think Garrett has made a 5-bolt T3 housing, mitsubishi bolt on turbine housing or T04B compressor housing for years (if ever)?

The above turbochargers seem to be Garrett center cartridges with Precision housings. Thus the turbine and compressor flow maps available on the Garrett web page are not completely accurate since those maps reflect the Garrett wheels WITH the Garrett housings and not the Precision housings. Correct?

 

The truth of the matter is that every Garrett Performance Distributor has the same opportunity to buy the same Garrett product as we do. A good reference for this would be the turbobygarrett.com web site.

ATP Turbo (another Garrett Performance Distributor) makes some really good housings as well, but I don't know if they have specific maps available.

There are many different possible combinations of Garrett GT30R's, but we can typically narrow down what's most suitable for your application.

For example, if you're building your own kit from scratch, Garrett has some really good complete out-of-the-box turbos you could build around.

If you're working with an existing kit where the turbo needs to fit as a direct replacement, we can come up with a suitable application.

If anybody wants to go over the Garrett GT30R for your own specific application, give us a call as we need to ask some detailed questions to be sure to get want will work best for YOU. Our number is (219) 996-7832 and we're open from 8:00 AM to 6:00 PM Central Time. Happy Holidays!

Good info! Do you have the HP rating on the GT3040R? Considering that it uses the same compressor wheel as the 35R, what would be the benefits of the 3040R over a 35R with a smaller exducer a/r and exhaust wheel?

 

I was just pointing out how there seems to be some confusion about the differences between a Precision turbo and a Garrett turbo. On the GT stuff, it sounds like Precision is using the Garrett CHRA and adding their housings. This can create some confusion as Garrett (to my knowledge) does NOT offer a GT30R (or any variant of the GT30R) in a 5-bolt Ford style turbine housing and T04B compressor cover arrangement.

As you can imagine, this can easily lead to a problem where one 'GT30R' might perform a whole lot different then another GT30R, even though they are both using '.63 A/R' housings or the same wheels, etc.

Know what I mean?

I do agree, custom housings made to fit existing applications can be VERY beneficial to some individuals.

What do you mean to NEVER run the water cooled center section on Garrett ball bearing turbos? I thought thats what it was there for...

I'm confused...

 

read it again he says never run them dry
