Garrett 57 trim ?s

[a1320eclipse]

I searched and found a couple threads of people talking about this turbo. Its the 57 trim with the .60 cold and .48 hot. Brand new with 0 miles on it. Picked it up for doing a tune on a buddys turbo honda. Im not seeing much positive feedback on this turbo on these cars. Seems like it would be pretty legit. So anyone with real world use of a real garrett 57 trim on their car. Ive got a 1g rod/2g piston motor, stock cams, 2.5" charge pipes, E85, 1600's, dsmlink, rewired walbro. shooting for about 25psi.

They suck on a dsm. I ran one on my car. Fully built engine/cams, on e85. It was the 57trim compressor, with a t31 stage 3 turbine in a .63ar t3 housing. Precision sells it as the sc3431. It was a lag monster, and when it finally spooled it flowed a little more than a 16g up top. Complete waste of time. It also surged above 25 psi. However, the 50trim, and 60trim wheels work great on a dsm.

I'd unload it. Like Donnie has stated, there are better compressor choices....and the .48 turbine housing will never really permit that compressor to reach it's potential on a 2.0 if you're running a boost level high enough to make the turbo worth having.

There is something weird about the T04E 57 compressor. the 54 trim and the 60 trim work fine, but something about that trim cut on that casting is just weirdo.

Weird. i guess i shouldnt have asked the question if i was just gonna use it anyway, but im gonna throw it on and give it a whirl. More of a curiousity thing now i guess. Ive seen the same 57 trim on a single cam honda (1.5L vtec) absolutly roll out on like 14-15psi. I wasnt really looking for people to say it was a bad turbo, was looking more for spool times and max boost #'s that kinda thing. Thanks for the replies guys. Ill report back in in a couple days.

On my setup, i saw 20psi in the mid 4k rpm range. Whenever i tried to run more than about 25 psi it would have surge issues.

My evo3 setup spooled much faster, had a wider powerband, and could almost match the peak flow of the 57trim, but across a much wider rpm band.

I ran the 57 trim because i got an awesome deal on the entire setup. I only ran it on my car for a week, it was that much of a mismatch to the 4g63.

I had the DBB 57trim. Spooled at 4K. Surged past 25psi with the to4e comp cover. Had to have a friend machine and custom fit a new compressor housing with surge ports to make the problem go away and even still it surged a little in 5 gear. This was a few years back when pte was releasing the DBB stuff.

Certain wheels are just inefficient from the get-go for some reason. When you look at the E54, E57, and E60 wheels on paper, there is only .120" of inducer spec difference between all three wheels. Their exducer specs are all the same.

It almost seems impossible that just one of these wheels would perform poorly compared to the next, but a good example is the Big 16G to Evo III 16G comparison...nearly identical wheel spec (inducer/exducer) on both wheels, but the Evo III 16G is more efficient to the tune of almost 4lb/min at peak by a superior wheel design.

I'm running a turbonetics T04E 57 trim with .63ar, I personally like it and have no issues with surge. It hits 24 psi at about 4200 rpm and pulls hard. I like it better than my evo lll, who knows, maybe turbonetics built theirs differently but like I said, I don't have the issues others are speaking of with experiences with my setup. Your best bet is to just try it out, if you don't like it swap it out for something else, turbo swaps are fairly easy to do after you do it a few times.

The Turbonetics "E" series compressors are completely different that the Garrett wheels. All Turbonetics "E" wheels that I've seen have the straight leading edge to the inducer (like the Garrett E46 and E50), where the Garrett E54, E57, and E60 wheels all have a swept- or rounded-face to the leading edge of the compressor blade.

Not sure if Turbonetics did their homework and designed the wheels to be this way, or if they were just trying to get around the copyright laws and dumb luck happened.

Did not know that, good info, thanx Justin

I run a 57 and although laggy, when the engine is built and supports the airflow they come on quite hard and will flow quite well.My 57 trim is in perfect shape as far as the CHRA but the compressor wheel is suffering major errosion from years, miles and failed air filters of the past and still makes 438hp on e85 at 29psi roughly. BUt ultimately if i didn't build it myself when apprenticing at majestic only because it was my favorite number (and it made the power i was looking for atthe time) i would now days choose a 50 or 60 instead.

edit: I have had some previouse part throttle surging on the highway when it built too much boost at 30% throttle and such, but nothing once wide open, and no other issues at all, lag maybe the biggest complaint, but on my car i come loose with a quaffe LSD on both front tires all through 3rd gear even.

No prob.

Just for reference....

Very different compressor design on those two turbos.

 

[turboglenn]

As well as having different major diameters on the compressor wheels (inducers are even different if that's a new T-netics wheel)

Do you have those turbos physically on hand justin? I've been livin with a 57 forever, and only need a good comp wheel to make mine back to perfect, but i'm looking at trying to get a t-netics 60 trim off a local guy here..having one of those you have there might help me in a good way if you're willing to part with them at a fair price (wether they are good or not, and priced accordingly)

Sorry, don't mean to jack the thread.. just can't stay out when i see the good ole fitty-seben

My Precision/garret 57 trim . Was just awsome! Best turbo i ever had!

I've run a 14b, small 16g, big 16g, evo3 16g, 20g, 35r, hx40, and the 57trim. It is last on my list in order of me liking it.

 

[superorange]

Well I believe this is the turbo I just got. I'm very disappointed to hear such bad reviews. I'm running e85 with a built motor, 272's and on link. Will this turbo really be a waste of time coming from a fp 18g to this? I usually run around 30 psi on the 18g and was planning on doing the same with this. How much is this turbo worth? It's in perfect condition just don't want to waste my time if its not a goo match for me

 

[JusMX141]

You can run it, just don't expect to make any serious power with it.

From the sound of it, it's not worth the manifold/wastegate/oil lines required to install it in place of the 18G.
