For what purpose? The more detailed your explanation, the more likely you'll likely get a real answer.

 

lag time......when i should expect full boost and etc etc

 

i dunno about ur motor, but i love it on my gsr. 18psi came well into in mid 5000 on my sc34, it was ungodly laggy compared to my 30r. This so far i've run about 10psi, and I get that around 4k. I'm sure once i get tuned it'll reach my old 18psi well before 5k.

Lag is still there obviously, it's still a fairly large turbo, but it's a minimal amount i think. I wouldn't trade it for anything bigger or smaller. I'm sure there might be some considerable differences on the y8, so maybe someone can chime in, but that's my experiences on the turbo.

 

yeah someone told me to get the 3071 but i want the 76

do you even know why you want the 76 instead of the 71?? It sounds to me that you've read too many other setups and based your decision on them....like TheShodan said, tell us what you plan to use it for and what your power goals are and we can give you a better answer....you might not need to spend the $1000+ on a ball bearing turbo depending on your application....their use is completely misunderstood it seems....

 

y8 im gonna fully build it and sleeve it but it is gonna be my dd...and lookin for 375+

 

look in the FAQ and i believe there was a GT28RS blowing the GT30 out the water

 

i agree with you, IMO the gt3076R is too big for your setup based off of your power goals and to the fact that other turbos will get you that power athalf the cost

as stated before, sleeving dumb at that power level and so is a gt3076r.
rods/pistons/and a standart t3/t4 will be fine and save you $1000+

a bb turbo really isn't necessary for your goals-just a properly designed setup

 

IMO sleeved MIGHT be a good idea IF he plans to start with that power level and go up from there. HOWEVER if he doesnt plan on making more whp than his sleeves can handle, then it would be a waste of money , however boosted applications are so adicting and ever changing sleeving the block would give you an endless ammount of power range as long as your tuning and turbo kit can make it that is.

 

exactly im goin for 400 plus

 

then sleeves are definitly in your best bet, depending on your final whp goal that will determine what kinda turbo you need, if you know the whp you are looking to make specificly, then you can choose the turbo that is best for your power goals, you dont want to overkill the application with a high whp turbo but dont want to undercut the whp of the motor by choosing too small of a turbo. a happy medium is definitly what you are going to want.

the gt3076R might be good for your application given the specific specs of the overall build, but its hard to tell without an indefinite whp power goal 375-400+ you can make good whp with any medium size turbo and smaller AR , 450-500 the gt3076R might bwe good if you are running a little higher compression ratio like 9:5:1 ect definitly dont want to undercut your setup. as for the turbo being too large it all depends on the application at hand and how much psi you are looking to push and how much whp you are looking to make ect that will determine if its too large or not

You know the "plus" part is always a reality when going turbo...So I say sleeve and use the 76, because it is very capable of doing 450-500whp which is not out of the question after you get used to the 400whp. . . .

Don't limit yourself on injectors or your clutch either, no point in buying ones that max out at 400whp if you're going for more in the future....

 

i still say 3071r. it'll support up to 460whp and is slightly smaller and will give better response on a smaller engine-like any d16-and still some room to play.
now if by400+ you mean 500ish, then i'll vote for sleeving and the 3076r all day.

 

i just bought the 3076 for my s2000. which is a tad on the big size for what i want, but i have a high reving good breather 2.0 motor, so it makes more sense for me

 

3076 here with the .63 on a stock z6. I see 10 pds at 4500 and have no complaints. It just went 12.9 on 22" slicks and feals like the perfect turbo.

 

yeah im gonna be using the vitara and eagle setup and lookin to make 9:0:1 CR and yeah im sure ill turn up the boost more and more and have more power than im saying i want

i was just thinkin about the 76 cause i wont have upgrade turbo if i want more boost, being if i got a tad smaller turbo i would probably have to upgrade

but i definately get what ya'll are saying and im gonna stick with the 76 thanks for the input guys ill keep yall up to date

I would agree with this, and there are plenty of others that would work in the journal bearing area as well. In fact, one does come specifically to mind....
