Thoughts on the GTX3067R

[zandrew]

I am thinking about going with one of Garretts GTX3067R instead of a different turbo. I currently have a GT3071R and I like it very VERY much. I am hoping that the GTX3067R will match its flow potential but offer slightly better spool characteristics.

I am shooting for 350AWHP.

Get the hta upgrade. Essentially the same thing

Only problem is the GTX wheels are designed to spool slower seeing the 11 full blades do not move as much air at lower wheel speed. If you want quicker spool then your GT3071r just get the HTA 71r wheel upgrade like Ray4624 mentioned. Thing is with the HTA upgrade on the 30r turbo you end up with a .70 a/r compressor housing unless you ask them for something different. They also offer a 73mm and 76mm HTA wheel option for your turbo. They also offer a 68mm HTA wheel but I don't know if they can put that into a 30.

The smaller back plate and lghter weight allows the GTX3067R to spool faster but flow the same amount as the 3071R. I am in touch with a company that has dyno tested the GTX3067R, GTX3071R, and GTX3076R as well as the GT3071R and GT3076R. The GTX3067R spooled about 300RPM sooner then the GT3071R and made 20 more FWHP at the same psi. They are selling the turbos off that they used and I can buy either a GTX3067R or GTX3076R that is lightly used for $650 shipped.

I like the hta stuff BUT this is an excellent deal and honestly I am thinking about buying both.

[ray4624]

Were those tests on a 1.8t?

2.0. The effectiveness of a turbo from one make to the next is fairly comparable. If a gtx3067r spools 300rpm sooner then gt3071r on one make It should do the same on another. The turbo does not know what motor it is mounted too. To make 14psi on 1.8 will take No more exhaust energy then 2.0. The difference is at what rpm that engine makes the necessary energy to get it to spool.

If all you want is 350whp, then stay with the GT3071R. Run a T31 .63 A/R setup with decent tune and you will have 350whp with just drop in rods. It has been done time and time over. If chasing 400whp, then I would say the GTX3076R would be a decent choice. But with that being said, my friend has a GTX3071R, stock displacement, meth, Maestro Suite, AEB, and has to be around the 400who mark (not sure more of less). There is a video done by his tuner (J Fonz) with his car spanking a stage 3 S4 (not sure what turbos). Pulled on the S4 by 2 1/2 cars. The tuner made that video after tuning both cars.

Just seems odd that you went larger and are now working your way back toward the 2871 you already but a 11 blade wheel and a larger exhaust wheel. If you are just looking for 350whp then why aren't you going with one of the GTX28 turbos to give you the fastest possible spool up and still able to make 350awhp? The GTX2867 and GTX3067 are both rated at 48 lbs/min.

[landfill]

A gtx 30 turbo is bigger than a gtx 28 turbo.
What are you talking about working backwards.
The gtx series turbos are newer technology.
They are designed to spool faster than the regular
gt's not slower. Why would a company put out
an inferior brand new product lol.

You seem to have missed the fact that he already has a GT3071r and was just running a Comp Turbo. Before that he was running a 2871r before going to a much larger turbo and is now working his way back in compressor wheel size. I know it is a little hard to keep track of seeing he buys turbos more often then people buy socks.

A 11 full length blade is not designed to spool faster, they are designed to move air at full spool, the short blades on a 6/6 and 7/7 wheel are designed to help flow more air as the turbo is spooling up. Garrett did the GTX wheel to sell a turbo that has a much larger flow map, allowing them to move more are at a higher efficiency. They also went with the 11 full blade design to reduce the noise level of the turbo.

He says he wants the quickest spool possible while being able to make 350awhp. Wouldn't the best choice be the smallest turbo possible that actually can make 350awhp instead of going with a much larger turbo to just make that same power with a smaller power band? If I wanted to make 700awhp I sure wouldn't buy a turbo that can make 1200hp seeing that would just be plain stupid.


The GTX3067 and GTX2867 have a compressor wheel that has the same inducer (49.7mm ) and exducer (67mm). The 30 has a larger exhaust wheel then the 28.


Sorry to tell you this but the GTX wheel is not "new technology" seeing other companies sold a full blade wheel long before Garrett come out with their GTX line.

[zandrew]

Mike you have always had something against me for having multiple turbo options. I don't quite understand. Those oddly are just the urbos I have used on my Audi. I also have a GT2560, GT2560R, GT3076R, GT3071R (different one then whats on my car), GT2554, S2B, TD04 19T, TD05 E316G, T88, GT4202, Several T3T4, and probably about 10others I have forgotten about. I rebuild and upgrade turbos for people. Consequently I have ended up with a few from different trades.

You said working backwards and I guess so considering Compressor size but I guess when it comes to quality I am working forward. My Comp lasted less then 6 monthes and less then 3500 miles. You brought up full blade technology being old. Your right but your being a bit simple minded saying the GTX compressors are old technology. There is so many more aspects of the compressor design you have left out. Like fin angle, leading edge diameter, compressor design(through bolt, flat back, super back, hubless, and several others), compressor material, etc , etc. Garrett consequently sold full blade turbos a long time ago. The difference in the GTX compressors is that they allow for quicker spool times and higher psi loads and more flow. The GTX3071R flowes essentially like a GT3076R but spools faster. Yes they do spool faster when you consider compressor flow. The 3067 flows more then 3071 with 3.5mm less inducer and similiar exducer (when adding in the the extended tips).

The compressor is one half the equation. Yes I am sure the 2867R spools faster then 3067R but the 3067R can actually handle the extra capacity. The 28 turbine has its limits and honestly my GT3071R spools fairly similiar to my GT2871R and they were both 56 trim compressors. Also my GT3071R uses a 90 rim turbine and the shit-tastic .86 AR turbine housing.With both of those it still spools similiar to my GT2871R which uses a smaller turbine and had .64 AR housing.

The difference in buying a turbo that makes 1200hp on a car with a goal of 700 hp is silly anaolgy. That is 50 lb min difference Mike. The compressors in my equation flow the same. The other part is I have only seen one GT28 turbo make 350AWHP and that was a GT2871R that was fully built and even it flattened out by 6000 RPM. The GT3071R with the same compressor can knock down 400AWHP and after using both the GT28 and GT30 I like the characteristics of the GT30 a lot better (though I have the WG version of the GT30).

Are you saying since the Garrett GTX compressors are "old technology" they are not a good turbo? If thats the case then Precision and Comp should not have a market. Technically the first turbo to be offered to the aftermarket was Turbonetics. Precision simply is nothing more then Garrett turbos. Comp took aspects from different makes and mixed them together. The billet compressor is old technology. Garrett had 7+7 design back in th 70s. Borg used ett 10 years ago. The turbines are just rebadged old Garrett technology. So which turbo really does offer something new completely one off and different with all leading edge technology? I know its not Garrett since the GTX line uses everything from the GT line minus the compressor. The EFR is my choice but unfortunately it ous of my budget currently....

What I was wanting to know is if anyone has tried a GTX3067R yet and if so how they liked it. I don't think they have been used yet.

[nynoah]

GTX turbos are new marketing technology...

[zandrew]

I think the GTX is more of an upgraded version of the GT series. My interest for a turbo is to fulfill this set of gudielines;

-400AWHP capable incase later down the road I change my mind
-quickest spool possible while still being able to fill the rev range up (redline 7200RPM)
-Easy to adapt

What I intially wanted to do was use a Comp Turbo Compressor in my GT3071R. After the merry go round I have had with Comp they can eat $h!t with a dirty spoon for all I care (which sucks since I like to support small USA based companies having had worked for several). I am really not displeased with my GT3071R at all but I would like a lil better spool. I feel the GTX3067R gives me the flow of the GT3071R but better spool like the GT2871R and allowing it to pull better then the GT2871R with the larger turbine. The GT3071R (and 2871) compressor flows 46-47 lb min at 21psi and the GTX3067R flows the same 46-47 lb min at 21 psi.

I think it gives me the best of all the points you are looking for in a turbo without having to shell out a boat load of cash. If I had the money I would probably go with EFR 7670 but I don't have it.

Eat the cost and go T3 .63 A/R. You will want a T3 anyways with your power goals. Try it out on the GT3071R and go from there. If you don't like it, at least you can say you tried it out. And at that point, you can upgrade to a T3 GTX setup.

[zandrew]

I already have the T25 which is the housing you are referring to but it uses a T25 flange instead of the T3. I was planning on going GTX3067R mated to the T25 .63AR housing and use my Tial wastegate. Have it tuned properly with 21psi and 28 psi options.

I don't think he can, since the the WG Gt3071r uses a different turbine that the T3, its a little smaller.

Avant I have that housing already. Its called a T25 plus which is essentially a T3 4 bolt .63 AR housing but it has a T25 flange instead of the T3 flange. I plan on mating it up to the GTX3067R turbo and running it with Tial wastegate instead of internal. You can actually get those housings in GT28 turbine as well.

Really what I was wanting to know is if my thought process was correct on the 3067 flowing enough for my goals and also offering better spool charactersitics of the 3071? The .63 should actually help with spool since I am already using a T25 .86. I think for my current goals the 3067 is the best fit with exception of some higher priced turbos.

Nothing against you, just stating the fact that you have changed turbos more then a few times.


Have you even considered a BW/Airwerks S200 with the FMW wheel?

[zandrew]

I liked the 2871R but I wanted to try the Comp 5552 I bought that I had plans on using on my 2.0 block. The 5552 crapped out and I wanted to get it fixed but ... well you know. I am now on the GT3071R because I had no other choice except the GT2560 and my tune was on the big side for it. The GT3076R is too big for my goals and too much lag. I think you think I can't make my mind up what I want and that is why I have tried different turbos. Its more like I have changed my goals and now I am building my block I want the next turbo I buy to be the last. I "think" the GTX3067R offers exactly what I am looking for and considering I can snag this one for $650 I think its a steal.

Those S200 are nice turbos but they are too big as well. Look at their flow rates but I know a lot of people swear by them.

[ray4624]

650 with the exhaust housing? That's pretty legit then.

You've already got the gt30 exhaust housing anyways so why not.

The GT 3071r with T25 has a 56.5mm exhaust wheel, while the T3 runs a 60mm. My counter was to Seerlah, who suggested you switch to a T3, but I guess you could but it would have to be for the smaller exhaust wheel that came specifically on the T25. Another thing you have to consider is the GTX3067r also runs a 60mm wheel, so I don't think its going to fit in your T25 housing. Double check with Garrett though. The GT3071r has been my turbo target in turns of power, so I've read up on the variations.

From Garrett
"Turbine wheel cast from "Inconel" material for extreme applications Wastegated version of the GT3071R uses specifically-modified GT30 turbine wheels for use in the T25-style turbine housing Turbine housing flanges are outline interchangeable with GT2554R (PN 471171-3), GT2560R (PN 466541-1) & GT2860RS (739548-1) "

What ever came of this did the op ever get the gtx3067 and try it out i am very curious i still cant find shit for info on this turbo
