Garrett gtx3584rs!

[vollosso]

How has no one run this turbo yet??

I have been tempted to buy one and stick it on something just to test it. It looks like the perfect turbo for us.

If someone has a built motor and is looking for a turbo or preferably a turbo and a tune hit me up and I’ll make you a killer combo deal.

It does look like a pretty sweet 700-750 rwhp turbo. Probably more if you run it on kill mode, but I don't know if the turbine wheel can reasonably flow that much even with the big housing.

Turbo technology has made huge jumps in the past 20 years. The 80's to early 00's had very little advancement in comparison. A 700+ rwhp turbo back 20 years would have absolutely huge wheels and need a huge engine to push it.

Exactly what I’m thinking.

Garrett finally updates their turbine aero and nobody notices hah.

It looks like 5-10% more exhaust flow everywhere. I have always thought the 35r was too small on the exhaust side for our motors.

I’d grab that 1.21ar and send it on e85.

Full boost by 3500 and 700whp at ~1.5bar boost. About all the e36 chassis can really handle.

I've been waiting for someone to show me 1000hp out of this turbo because it seems like snake oil. A local Garrett sponsored team were slated to do just that this year on their 2JZ drift car, and they quietly went back to the gtx4088... Might mean nothing but I'd like to see it match the gtx40, or surpass it as the literature claims it does.

it has a bigger compressor and turbine than a 6766 and makes less power. Calling it a gt35 isn’t going to make it spool like a 61mm

Uh, no.

It’s considerably smaller... and rated for more... why the negativity?

Compressor 67/84
Turbine 68/62
Rated 1000hp

Im just not a fan of this turbo or their marketing behind it. It’s not in the same class as a gt/x35. Rated power doesn’t mean shit when they post the compressor map next to it showing less than 90lb/min

Exactly why I wanna try! Someone just has to want to!

When/If Garrett ever makes a G series 30/35 frame turbo, you will regret getting this. The G25-660s have already outclassed all existing 30 frame turbos with respect to HP and spool. G25-660 has made nearly 500whp on AWD Subis, but it's probably choking a 3.2l with it's tiny housings. G series are going to be great for this platform due to how compact their design is over an EFR. They just need to release them in a frame size that works with our 3.2l. I can't imagine an equal length manifold, twin scroll G series spool.

I remember the gtx3584rs looking pretty expensive. I think the cost is pretty comparable to a EFR9180 if it really is a 1000hp turbo.

Either way, it looks like a big improvent for a turbo of that size. Im sure someone will run it, just takes time for someone to start a new build thats not on a tight budget

[NY98M3]

I believe Hayyan is using this turbo...

[PEI330Ci]

ATP now has a twin scroll 1.06 A/R housing for this turbo, so I was highly interested.

Ideally, you'd do a back to back test between the GTX3582R GEN2 and the GTX3584RS.

Personally, I think this turbo is going to run out of turbine flow far before the compressor runs out of breath. And I also doubt that it's a 1000hp turbo on most engines....

Before this was released to the public, someone ran one on a BMW engine and found that it was slower to spool than the GTX3582R.

As usual they are like 8 years late to the party but it looks like a nice 800 whp turbo for the extremely space constrained, but I think I would go for the bigger turbine on the gtw3884r and save about $800, or better yet if you can fit it an efr9180

We maxed out a 6765 gtw with the largest t3 housing. 720whp with weak spool

So you think going to a smaller turbine wheel is going to help matters? The turbine map on the garrett site for the gtw3884 with a .96 AR flows almost the same as the 1.21 on the GTX. You can get up to a 1.32 T4 for the GTW which will probably flow 38 ish lbs a min.

[someguy2800]

I guess what I'm trying to get it is I can't see what I would use this for. I don't think its going to do better anywhere than a 6466 which is cheaper, and its not going to get into the same class as a 6870 or 9180, which are also cheaper. The turbine wheel is probably a better fit on a 4 banger.

I don’t think it’ll ever be in the same class as a 6870 or 9180. I think the gtw release was a total dud, it was a marketing release with minimal, if any, improvements. Trading as a cheap Garrett to compete with pte.

In my eyes this is the first major release from Garrett in three decades. This is the first time they updated turbine aero since the original 35r. And we have done 700whp on the gtx35r. I have tuned cars at 600whp at around 24 psi on a gtx35r more times than I care to count.

This turbo is a good step up in turbine flow almost to the gtx4088r on paper.

I think it’s an excellent *looking* turbo for a 750whp car with more bottom end than a 6466. And I think it could be pushed into the 800s with enough effort.

We tried the gtw, I wanna try the RS and it may be the last Garrett I put on a car hah.

Guy on the supra pages on facebook did just under 900 whp on a 3584RS. Said turbo was ALL IN and boost fell quickly and couldn't be held to redline. Spool was stupid. Thing made rediculous torque.

Surprised it flowed that much, but it was probably out of turbine flow more than anything on a reasonably sized I6. As someone else said, it is probably a better fit for a "larger" 4 banger like a 2.3L or so where you can use the larger compressor to get your pressure ratio up to where the turbine starts going. Most Garretts are actually sized this way, too small on the turbine if you're running a PR less than 2.5-3:1 on the compressor when you max it out.


That said, the cost aspect of modern Garretts is really offputting. I'm a big proponent of the IWG EFRs where you can fit them. With their discount from MSRP to street pricing, plus the fact that they come with everything you need for a turbo to work, really makes them very cost effective. Plus I'm not a huge EWG fan, so there's that...

[pbonsalb]

Unfortunately it seems like the EFR often require an ewg in our application. I run both iwg and ewg. Neither alone will control boost — I had an EWG only EFR before.

[wazzu70]

Garrett charges a lot for what they give you. Not sure why they do that, but they havent gone bankrupt yet so I guess it works. If they want to charge premium prices they should offer a premium product. Their quality is not bad, but they are not technology leaders.

I still think a lot of that is the turbo manifold designs most of you guys run. I could run ~3 psi to redline in a 100%+ VE engine on an EFR 7163.

I used to think that too, until I had the plastic bearing cage blow the F up on my car on a <3k mi GT2871R. Granted it happened on track, but oil and coolant temps were fine, and I wasn't pushing the turbo that hard (~100k RPM max speed). They would give me like $100 off street pricing for a new CHRA, that's it. Basically made the turbo an expensive paperweight. I haven't purchased anything from them since, don't think see that changing anytime soon. Going EFR on the early '90s JDM nostalgia build.

These are my thoughts as well. The IWG has worked on every other platform it's been placed, and there is nothing magical about the M/S 5X engine that is fundamentally different.

Packaging isn't easy and it takes a great design to make all of those things happen. Equal length, twin scroll, packaging it to fit, low mount turbo, and decent WG placement. It basically locks you into an investment cast manifold with tight fitting runners.

Agree with whats been said that the price per HP just hasn't been there lately with the Garrett. If borg warner EFR didn't exist, which a few years ago it didn't, your options were to roll the dice with a precision turbo (could go 20k miles or could go 2k miles) or go with an expensive garrett that didn't perform anywhere near what precisions are doing.

With the EFR now out I would say that's your best bang for your buck that will actually last unless garrett starts adding "G-series" upgrades to their whole turbo line.

Honestly if Garrett could give me Precision HP but with Garrett reliability, I believe that would justify the high cost of their turbochargers, but I just don't believe that can happen without sacrificing reliability (the precision shafts are quite small, but it does allow them to pick up surface area on their wheels hence the better performance)

Ah well. We can't have it all I guess.

The G series is crazy expensive compared to EFRs, and I really don't believe a minor aero update on the turbine wheels gives anything like the impact of going to a TiAl wheel of the EFRs. There's a pretty decent discount from MSRP to street/wholesale pricing for Borg Warner turbos, but that doesn't hold for Garretts.


It also pisses me off that Garrett used to talk about how their plastic bearing cage was "not a weak spot" for years, then quietly updated it with their most recent stuff (from what I understand, they're a little shy on details). That's what blew up and took out my GT2871R, and I used to really defend Garrett's reliability before that. I think their turbos are much better engineered and manufactured than Precisions (that's not really hard...), but they have their own weak spots due to corporate cost cutting for a VERY premium priced product. The EFR lineup I feel really deserves its pricepoint, as I've never been disappointed after driving one. Sometimes they don't put up huge dyno numbers on all out drag type builds, but for the tiny bit they give up there vs. some others, the experience of just driving the turbo is unsurpassed.

I do wish BW would update the compressor wheel aero on the EFR lineup, as it has been quite a while since they came out with it, but the BW machine moves slowly. In the meantime, they put out the best aftermarket turbo there is right now unless you've just got to make max power on a specified inducer, in which case - welcome to the exciting world of Chinacharge... I mean Precision turbos. (I know, going to get some hate from this board, but those things are just NOT well built turbos...)
