Garrett GT4094R turbo ball bearing

[wishihadatalon]

Who told you that? Are you sure they weren't referring to a 4088?

He was referring to them both.

"a 37R is just a T67 ball bearing! the GT4094R sucks ass, too big a compressor wheel in a small compressor. and the compressor is a lot bigger than the turbine housing so its a weird turbo to boot.

the 37R is wicked and will almost make the same hp as the 4094R with about 700rpms better spool time."

That is quoted from the guy.

The inducer on a 4094 is basically the same as a T67 wheel with the exducer just being larger. It isn't that much larger.

Who is that quote actually from?

I've read similar things on many other car boards that use these turbos. They all say the same thing. You can get similar power/track numbers out of the 4088 and if you want bigger you might as well get the 4294. They all say that the compressor and turbine are missmatched as stated above. I dunno...I just wasn't willing to deal with the guessing.

Well, that all played into my decision...just skipped it all and went with a 4202.

He is from Detroit. I don't wanna call him out or throw him under a bus so I won't give names. But this thread has given me plenty of info to make my decision.

Its not that that turbo is too much for me, its that I really don't wanna do all of the cutting and super special stuff to my car with a top mount manifold. I was looking for a manifold that would let me run it somewhere else but I wasn't able to find anything except maybe an AMS manifold that isn't out yet. And all I really want out of the car is 140+mph traps. I feel a turbo smaller than that should get me there.

From what the folks at AMS said the t04z was likened to a ball bearing t67 and the 37r is the "GT" gap between 35r and 42r. They said 300-500 rpm later spool with 75-100whp greater potential (compared to the 35r). They've released a kit not too long ago for the evo and I read like a 14 page thread about it over on evolutionm recently. Looks as though they are pushing the 37r more than the 4088 because they say it is way laggier and only has slightly more potential for power.

You can buy that turbo from any pte supplier for probably less than what ams will let it go for. I was looking at it and have almost thought about buying it. I was also looking at a gt3788r which should make a little more power than a pt67bb a spool in the same ball park. I am still contemplating getting a pt67bb but with the gt3788r I can get the tial ss turbine housing that comes on the 35r and shearer should be releasing a v band tubular manifold soon. What a dilemma

 

[JohnTSI]

I had a dbb t67 on the car befor this turbo. If I had to do it again I would have probably went 4202R since to me this turbo is not as laggy as I expected. But it is much cheaper to run this without going top mount etc. I will try to run it a lot harder next time out I just wanted to make sure it was gonna run befor I leaned on it too hard.

Its in a divided 95 turbine housing

 

[definitiveno]

What exactly is not too laggy if you don't mind me asking?

 

[JohnTSI]

40psi by 57-5800 rpm on a 2.0 without the bottle.

 

[wishihadatalon]

How fast do you expect to go with this turbo? Thanks for all of the info.

 

[JohnTSI]

We will see, goal for the car this year is 150 and mid to high 9s still granny shifting.

That would be awesome. I wish you the best and please keep us updated.

 

[NewTurboTuner]

The problem is that myspace is limited, and in addition spool is amazing. By 4300rpm I have 13 psi already. This turbo unlike the gt4088 is rated at 850hp, a little less than the gt4294 but is a better spool .
I dyno next tuesday, will let you know the results.

Next Tuesday was over 3 months ago
.......wheres the dyno sheet?

Well decided to go back and try to continue tweaking the car today. Wanted to go all out first pass so i could go back home and watch the NCAA games.

First pass of the day 2 step 6k antilag 5200, loaded it on the ebrake. Then I screwed up I couldn't hold it still and rolled through the lights, timer is going I am creeping but I was waiting for the boost to come up where I wanted it. Let it go between 16-20psi and took off. Would have been a good 60 had the timers not started half a second earlier.

Next pass I didn't come out on enough boost and bogged it hard, about half track car started getting real swirly and I saw steam from under the hood. I let out just past the 1000' car was all over the place. Pulled it around and I had lifted the head it seems, filled the overflow and was spraying on the l/f tire.

Guess for me I have reached the limits of this MLS with no Oring, passes where made at between 36-37 PSI. Pulling the head and oringing it this week

which head gasket are you going to put on after oring`ing?

 

[JohnTSI]

SS oring with a stock MLS is what Shep reccomended.

 

[silkcity100]

where are you going to get it?do you have a part #,tnxx

 

[90laserRSfwd]

Sorry to bring this thread back from the dead but I am debating now about selling my 35r and getting either a 4088 or a 4094 and I don't know what would be best. Looking for mid to low 10's around 130 to 140 mph. (91 tsi awd, 2.0L, bc 280 cams, dsmlink, 1150cc inj.'s, etc.)

 

[Turbo Monk3y]

Hmmm Seems that the only 2 people I know that are fast with the 4094R is Johntsi, and Tony N. whos car is sponsored for this 2007 season from extremepsi.
EXTREME PSI : Your #1 Source for In Stock Performance Parts

Both run this turbo with great results, but why there are so few running this turbo is beyond me...

You should be able to get those times with the 35R.

That's the fastest cars with Dsmlink list. Notice that almost half of the cars in the 10's are using a GT35R variant of some sort.

would it happen to be 72mm?

My firend has this turbo on his car from teh last shop that blew his motor on the dyno and told him it was his resposibility to pay for the rebuild. ( so now he doesn't go there) His receipt for his turbo says it's a PTE67 something with a Q trim turbine. The power output is somewhat impressive, but this thing soesn't make full spool till about 5200RPM (similar to the on above) We've both been trying to figure out what the turbo "really is". From teh reputation of the shop he went to, it could have been pulled straight off a tractor out in the country for all we know

Inducer on the 4094 is 70mm.


And the quote Mike was referring to is quite the crock. The T67 is good for 700whp in an absolute perfect world at 2 billion psi (dont even think about posting some BS inflated dyno numbers here) and the 4094 should make 760-780whp in the high 30's psi region in our motors with an efficient set up.

As for what I will be trying next season (if ) I ditch the Twin turbo's..

He was trying to make upwards of 650+ on the previous turbo (regular T67) and almost did. I think he was maxing out at around the 630 range. Until the turbo grenaded, then he went to the "PTE67-XXX" not sure of the entire # on it, but it was supposed to be better than your standard t67.

I hope you weren't referring to me about inflated dyno #'s. I don't' just talk out of my ass, and only give #'s when I've seen proof of them. and i don't believe I've posted any #'s except my best dyno results here that i can think of.

Back to the turbo. The bad part is he couldn't make 300 on that turbo the last time the "other shop" tuned it and it still blew the #1 piston apart at the wrist pin connection point. A look at the map solved that,(can you say 14:1 at WOT and 47* timing advance under almost 30 PSI boost..IDIOT TUNER) I retuned it and although we don't have any #'s we've already come close to doubling the 290 horses he was getting at the last place .. Like i said, no dyno #'s but the seat of the pants dyno would suggest upwards of 450 or so. It will spin all the tires it can with a welded center diff and AWD through 1st gear. The car is a 99 GSX. This car has every part i wish i could have for mine. he's probably got over 60k worth of aftermarket goodies in his car including CF EVERYTHING.. EVEN the roof and rear quarters are getting wrapped by hand in CF, and I'm clear coating it as he completes each part of it. He forgets to pay his mortgage from his parts buying sprees sometimes .

sorry i got of topic there..
