Garrett 3076r Internal Or External Gate Rear Housing To Small?

[lookingforboost]

Hey guys i have a R33 that has the following mods

Trust catback

3" dump pipe

de cat

blitz pod

boost tee 9psi

walbro fuel pump

Last time its returned 255hp 188KW at 9psi (dont want to go any higher and goes into R&R after10psi)

i have a Power FC, plazaman plenum, front mount and tomei FPR to go on next but turbo choice

Is the 3076R to small with the .63 rear for the 25? and would the internal gate or external gate be better i would love to run external gate but is iit worth the extra money

i want fast response and good midrage to redline pull i want to use the car for daily driving, drift and every now and agian drag and curcuit. power comes second to response and relaiblilty for me i wont be pushing it to the extreme but i want headroom.

Yes i have upgraded all the suspension and braking in preperation for more power

IMO the .63 is to small for the GT3076 (given its a 300rwkw(+) turbo).

If you want super response and a .63, then a GT3071 fits into the equation there much better.

It should make around 250rwkw give/take and should still hold nicely to redline. It won't be anywhere near the top end the GT3076 will have (in a .82)... but all comes down to what you want.

More response or more top end. Something always has to give.

External gate is not required either way.

Are you using factory exhaust manifold or not?

[Sheriff Wan]

Might need to add injectors to that list also.

Agree with Nismoid, potentially you could also look at something like a HKS 2535, might sacrifice the headroom but will provide the response.

3076 .82 is still boring and small

go bigger if u want something that will scare u a little.. maybe 3582r .82 mmm

way to much lag for a 25. I wouldnt go that setup unless it was a 3litre. Even still i think the gt3076r 0.82 in a 3litre would be my first choice.

Id go for an external gate. I regret not getting one on my gt3076r

might be a bit laggy but once it comes on its fun

3076r arent exactly the most responsive turbo either. i dont see 20psi until 4100rpm

How would it scare him making 300rwkw?

All it's going to do is be overtly laggy for the power and a silly suggestion really...

If there was intent to make 370-380rwkw then fine, GT35...

Fact is he isn't so getting a turbo that's oversized, for upto 300rwkw, and will make it overall slower - totally against what the OP wants anyway.

The 0.63 housing would be nice on E85 - may even see 300rwkw.

cause ive got near 300rwkw with 3076 .82 and its boring only going off proof been in 350kw gt3582 and let me say alot more fun and alot f**king faster, but hey thats me

[l0WRB]

Also got a friend with a GT3082 .63 and its making 285kw and it feels good, dif not 2 small turbine for gt30 series turbo.

Has it made that power on more than 1 dyno?

[l0WRB]

only been on 1 dyno and its pretty much spot on for power figures

lol already bored with the 3076? should've kept your old turbo and get a set of cam gears . Well. I'm making 321rwkws out of it (hypergear build 3582 in .82 housing) at moment. I'm seeing full boost on 4300RPM, not much on 1st and low 2nd. but 4000rpm+ on 2nd, 3rd, 4th it flys. Need to get more traction.

and you need some thing bigger then .63 to work with a GT3076 core. But should be good enough for about 270rwkws mark if you can hold boost.

He has a factory motor mate... come on... use some logic.

Of course a 350rwkw car is going to be more "fun" above 100km/h than a 300rwkw car. On the street however you've gotta argue what's going to actually be faster.

Mine with 280rwkw is virtually perfect, when it had 370rwkw it was just impossible.

Running 350rwkw through a factory motor that is going to see some circuit/drift... It won't last very long at all.

With a 3071 it will cover EVERY single base thing OP wants and still be in the realm of reliability.

yeah i understand nismoid.. just dont want him bolting on a so called balanced turbo that isnt going 2 give him that "wow" factor lol not saying 3076 is completey boring but it just doesnt cut it i dont think even for 300kw range hey.. maybe im fussy?

sell it to me then...pm me if you REALLY want to get away from it.

must be internally gated though

Boring??? Small???

The 3076.82 i had on my car produced 370rwkw and had full boost by 3900rpm. Smashed anything on the rd and IMO a more of a handful than the GT3582.82 i have now.

Light switch power from low RPM compared to the gradual push of power from the 35R.

They are not as laggy as you think, a mate is running one on a stroked 2.4ltr 4cc vr4
