Sparky, i try to read a lot about the things that i am interested in and since i am looking, i am always open to opinions. A ported (or enen not) atp 3071r why is worse from a 20g? (Speaking 100 octane between 23psi and 30psi)?


Also, i have already a TME turbo that spools nicely but overboosts at 30psi and goes down to 25psi at high. If it is to pay some money, not looking to get only 30-40whp. Does not worth it for me opinion

 

i have the 16gtme turbo,made 370 on pump gas..

 

Nicolas: I am not trying to give you a hard time. I think that the 20G-LT is a better deal than any 3071 kit, including the ATP(maybe I'm wrong). It will spoolup faster than the 3071 and should be capable of similar numbers on your 100 Research Octane Number(RON) gasoline. It is a better pump gas turbo and spools faster and costs less. The 3071 may have a slight advantage on racing gasoline.

If you want more than the 20G-LT can deliver then you would need to go bigger than the 3071. The 3071 and 20G-LT are quite comparable and similar, and in fact, you could say that the 20G-LT makes the 3071 redundant at best and even perhaps obsolete, given that it spools faster while flowing the same amount of air, and bolting right up to your factory exhaust manifold and downpipe.

Most of the other turbo options that have considerably superior high boost capability compared to your TME, have a whole lot more turbo lag. The 20G-LT only spools about 400 RPM later than your TME, while the 3071 is noticeably laggier. But hey, to each his own.

 

After more research i saw that everybody more or less feels/believe believes the following. However i did not find any dynno data:

1. 50trim can make more power than 20GLT
2. 3076r (and 3071r) can make a little bit more than 50trim in higher boost and better gasoline.
3. The best for pump gas is a 50trim and not 20GLT.


ATP is giving 3076 for $1350 (Dual Ball Bearing GT30R). Is 20GLT in a better price? $1700 was last time i saw. If yes, please let me know because i am interested. 400rpm more is not lag for me. The only thing that holds me back it is that some of you say ATP products are no good. Why is that? Any explanation please?

 

Anyone????? Other opinions????

 

ATP=Garrett....how can it be a bad product?
its one of the kits Im considering also over the 20GLT
just add the FullRace manifold

 

The ATP turbine housing used for the kit in question is not a Garrett housing.

FYI

 

I am also considering a 3071 over a 20GLT,

... the 20GLT needs like 30Psi to make the big numbers most people claim its good for but my feeling is that a 3071 on lower boost like 23psi should make similar numbers.

Most people say the 50Trim is the best pump gas turbo but technically the new technology Garret wheels on the 3071 make it the better turbo...

.63 Exhaust housing on a Garret should outflow the hotside on the Green?


Too many oppinions and too little objective answers.

The Ultimate for me would be EVO 9 Bolt-on Turbo thats Ball-bearing with like a 49lbs Compresssor wheel and a TD06 Exhaust wheel...

.

 

In reality, I've not seen where a regular 3071R has demonstrated significantly greater power potential than the FP Green, probably because there isn't much of a difference.

Where the difference between the two is far more evident is the fact that a 3071R with .63 A/R T3 hotside is noticeably more laggy as compared to an FP Green, which is why it isn't more popular than it is with this application. If the 3071R is configured with a .78 A/R twinscroll T3 however, the picture appears to change rather dramatically.

 

OK, So the ATP GT3071 with a .63_Hotside is not really significantly better than a FP Green... But it is about $300 cheaper and your Downpipe can be modified to fit onto it... hmmmnn

Saw on EVO 400 they offer a Ball Bearing Conversion to the FP Green...

If someone made a EVO 9 bolt on Turbo like the FP Green with a Superzilla 49lbs compressor wheel and a larger Turbine Side that bolted straight on like the Stock Turbo, what would that be equivalent to? GT3076?

.

 

unlike most of you here...Im looking for a turbo to bolt onto my oem manifold for a more stealthlike oem look....something bigger than stock to get me around 400whp around 24psi and pumpgas...it might be alot to ask but its what my quest is for...does anyone have a gt35 that bolts up?

 

You could wait for the often rumored EvoRed from Forced Performance. Also, if I wanted the power that you´re after on pump, then I might look into a twin scroll 3076 setup. Although, it wouldn´t bolt up to the stock manifold. You might be able to get real close to your power goal on 93 octane with a Green or a fifty trim if you ditched the fatory MAF and went with a speed density setup.

 

Comparing turbo's is fair enough however if you want a totally stock look from the outside the 20G LT is obviously what you would use.

 

I hope the rumored "EvoRed" is ballbearing and capable of 500HP that would be exactly what I'm looking for

.

 

when is that goin to happen
