GT6131bb vs te44, with stock converter on the street

[sugarandopium]

Need some advice....
I'm looking into upgrading the turbo while i still have the stock converter in the car to get a little more power.

From what i read, the 2 best options for a stock coverter are the GT6131BB and TE44. Is this correct?

Huge difference in price....
How much more power will i FEEL with the 6131 opposed to the 44.
I'm not looking for 1/4 performance, my car is just a weekend cruiser, seat of pants torque is all i really care about.

Is it worth spending the extra $$$$$$ for a 6131 over a 44?
Are there any other options for a stock converter?
Will either of these spool slower than the stock turbo?
I have no engine mods, just the usual first mods (fuel pump, hotwire, adjustable regulator, lt1 maf, translator, maf pipe, k&n filter)

I will be of course be purchasing a downpipe, injectors, and alky when i get the turbo.
Just trying to plan my next steps and am a little confused on what to do and how much power the turbos compatable with the stock converter will get me..
Or, should I wait until I get a new converter to go with a new turbo?

this is just my 2 cents...... I would wait until I could step the converter up a bit then get a little larger turbo....if you want it to feel like a stocker then you will need more converter....jmo....I have been there done that and bought the t shirt....you will get tons of opinions and ever car is different but you not going to spool like a stock turbo with out upgrading the converter also....a bigger downpipe will help however...buy once!! instead of 2 or 3 times...and get the good stuff the 1st time

Nice review on the 6262 w/ stock converter recently. Cheaper and should make more power than the 6131 BB.

your comparing Journal bearing and ball bearing versions.....

Yes... Still a better all around turbo I would think and should work w/ stock converter as posted. Manual boost controller will bring the boost up quicker as well.

Yeah you're probably right.
What is ideal for a street converter/turbo combo?

 

[jcawley3]

I have I 6162BB with a restalled stock converter...and was very unhappy with the lag....when the turbo comes up to boost I love it very strong..... just got a new converter so i have not drove the car yet...we will see.

read lots of good things about the 6262 they did not have that turbo out when I bought mine.....but if your like me and like the fast spool of the stock setup your are going to need to change your converter also.....

Turning up the boost on a 44 will introduce turbo surge/flutter. While 6131 will not. I ran about 20 with no surge anything above and hold on.

were you on the stock d5 running 20 on the 6131?

For a weekend cruiser with the stock converter the 44 cant be beat. Use the Garrett .63 ex housing for sure. Pay extra to use that housing if need be. The 6131BB will cost more require a lot more plumbing and probably wont make any more power at the boost levels you will be running.
Both will spool slower than a stock turbo without a converter re-stall.

I would also go with the 6262, ball bearing if you want quicker spool. Do what you can to open up the exhaust and intake for quicker spool and better response. I would also change the stall for.

Dont forget, an external wastegate/boost controller will help with spool also, and if you have a 6262 its a good thing to have.

It wont be quicker than stock with a stock converter. External gate will not help spool and is a waste of $.

 

[sugarandopium]

Thanks for all replies.
And very good point on the extra plumbing Bison,
I did not even take that into consideration,
was just comparing the two pieces $ for $.....

I really don't want to introduce slower spooling for a street car....
I'm getting the idea that I should just wait and get a converter and turbo together...

External gate wont help spool?
Boost controller does help the spool though?

I never said it would be quicker than stock, I said the 6262 gives a quick spool. Yes, external WG does help spool, its been proven countless times. They build and hold boost much more consistently. If you want to debate it, call any big tuner and you will hear the same thing. An external is designed for better boost control up top, but the second benefit is quicker spool.

I run a regular journal GT6131. I've been experimenting with a 2800 stall but the times in my sig are with a stock converter unlocked. I use a Boost Commander to control spool up. It's not as quick spooling as a stocker for the street but then again I don't waste my tires spinning everywhere with too quick of a spoolup. The 2800 allows much more boost to build at the line and spoolup is earlier. There's many ways to skin a cat. Alot depends on your goals and money.

I dont need a big tuner to verify if my internal gate is working properly. Post your proof of the external increasing spool up if you can and any of the BIG tuners you want me to call. The external gates need an outside source of pressure to keep the exhaust from pushing the larger valve open in high hp applications. So in many cases the external gate will cause a premature exhaust leak. Ive had both work fine on 10.0 and slower cars. Jason White still ran an internal on his TSM car. He won the TSM class this year. If there was an advantage to an external he surely would have jumped all over it.

Your internal wastegate might be doing its just, but they arent as good as external gates, plain and simple. Why else would they be used for high horsepower applications and internal gates arent?

Search google for external gates and quicker spool, Im sure you will find something. Search Subaru and Evo forums and you will see its common knowledge, Ive even seen datalogs to show that boost builds quicker. Who to call? Titan Motorsports, AMS, Boost Logic, Full Race... hell, ask Precision Turbo. They will tell you the same thing. Boost builds quicker because internal wastegates dont hold boost as well.

Ive never seen an external gate leak boost like an internal gate. All WGs need some sort of reference as to when they should open, internal or external. Most people buy a boost controller when they have an external gate anyway, why wouldnt you have one?

I was using a 2800 not a stock D5.
