real turbonetics...?

do you guys think this is this a chinese replica or a real deal...? i dont know what the going rate for a turbonetics is so im fairly lost on that. i know garretts are around twice the price though. i need a new turbo on my A4 since my K03s took a crap finally so now is the perfect time to go bigger. would this be a good upgrade for my 1.8T or should i look bigger? i was gonna go with like a GT2876 or GT3071. dunno if this is comparable.

I'm pretty sure that's just for the compressor cover, not a complete turbo

^This

Real Turbonetics, Garrett, Precision, Borg Warner, etc are all in the same price range. And prices vary depending on bearing and wheel types when it comes to the chra.

thats what i was thinking... would that be a good turbo size for a 1.8T though? as near as i can tell its similar to the GT28 series but like i said, i have no idea what turbonetics are in comparison.

T04E-50 is a very popular turbo for alot cars an platforms. Cheap turbo and rebuildable for cheap when they blow with journal bearings. E is the compressor housing type. 50 is the trim. So in general terms people are used to, that is a T04E 50 trim.

It can be ran safely on the stock block if the tune is conservative. This turbo is still capable of 300-350whp on pump gas, but the journal bearings makes the onset not too harsh. It is tq that snaps rods, mainly boost onset. But it is a very popular and cheap turbo that gets the job done.

i was gonna go with the garrett GT2876 or GT3071 because they are both around 60 trims i think. i wanna turbo bigger than i need so when i do drop in rods and valves i am already set on the turbo and wont be limited by it again. i am gonna do some more reasearch on turbonetics and broaden my turbo knowledge beyond garrett though.

TO4E-50

The TO4E-50 is smaller than either of the garretts. It's also journal bearing, while the garretts are both equipped with ball bearings. Unless you're needing to save a buck, I'd say wait and get the Garrett turbo you really want. The TO4E can get you into some good power, but it will spool slower and run out of air sooner than either of the garrett turbos.

After really looking at the maps, I'd probably go after the GT3071R, it has a much higher range of usable pressure ratios, and the fattest power range in the lower pressure ratios.

However FWIW, after considering the pressure ratios/boost levels (at the bottom of this post) used by most normal folks, the TO4E-50 really seems to stand up to he Garret's spec wise. Chances are you won't be pushing 30psi on those turbos. Any of them would probably do you quite well. The one thing that's undeniable though is that the journal bearing will spool slower than the ball bearings... Now if you went with a T3/T4 using a TO4 compressor housing, you could recover some of that spool... Also, unless I'm
mistaken, I'm pretty sure turbonetics offers ball bearing options for most of their turbos... At a price of course.

GT3071R

GT2876R

FYI: Pressure ratio of:
3 = 29.4 psi of boost
2.5 = 22.05psi
2 = 14.7psi
1.5 = 7.35psi

Oh and yeah... That price would scare the crap outta me!

Been on this forum board for a while and 300+whp on the 50 trim cracked a stock block. This is when people used to actually have fun with it, test limits, and why we have the info we have now. Think he squeezed it to around 330whp before he windowed the block. Thread floating around in the archives and guy lived city next to mine.

My suggestion is OP search more. I really suggest he do all at once. Meaning build engine with turbo he can utilize. Otherwise no matter the size, except the gt28xx, he is in lag territory regardless.

I run a turbonetics T04E .63 AR on my 2000 1.8T and let me say you guys are right, the turbo doesn't spoil up until around 3500-4000 RPM, but when it does....Holy crap, hang on to your shorts lol. I also built the bottom and top end to handle 8000 rpm and haven't noticed any "running out of boost" like some of you are saying. It pulls hard until redline.

For the price, I would buy it.

**VanCityA4Q** · 04-20-2016 01:35 PM

Also puts out 25psi of boost all day long.

**SynapticA4TQM** · 04-20-2016 01:35 PM

I said that about running out of air... But what I said was "before the Garrett turbos..." Not necessarily just running out of air.

Is that a straight t04e or a t3/t4?

**VanCityA4Q** · 04-20-2016 02:12 PM

T3/T4 makes a difference I suppose

Yeah a t3 turbine will spool a bit quicker than a full on t4 turbo

I think there's a little bit of confusion going on.

How so?

**Avant Nate** · 04-21-2016 07:19 AM

T3/t4 is an term for hybrid turbos. Still just a t3.

**SynapticA4TQM** · 04-21-2016 07:24 AM

Sure, but with a compressor side that flows quite a bit more than a standard t3? That's what I was getting at. Sure you will sacrifice some top end flow, but you will regain some spool

**Avant Nate** · 04-21-2016 07:36 AM

T04e is a t3. I may be wrong but t3/t4 is probably just a term from 50 years ago, when someone used a t4 wheel on a t3 turbo. I think that just about any bigger turbo would fall into that designation. i.e. 3071.
For what's it's worth, riding in someone's 50 trim is what really motivated me to mod my car. It was fast.

**SynapticA4TQM** · 04-21-2016 07:39 AM

Oh... See I thought when it said T -oh- 4 whatever... That meant it was a T4 framed turbo and then the trim referred to the profile of the turbine wheel.

Thanks for clearing that up.

But... Maybe I'm more on point than I think... Full-Race.com seems to operate on the same premise... Check out this screen shot of their listing/description of a Garrett t3/t04E ...

Turbonetics' website seems to offer the same explanation
