GT3076R vs GT3071R
I have turned of my GT3076R today, because my wastegate is blown away..
Now im thinking to change against the 3071 to get a better response,
so at the moment i need nearly 4000 rpm to get the full power.
But i dont know if the difference is big enough to justify buying a new Turbo?
Has anyone experience to the tell me how much rpm difference is between
these turbos to get full boost?

I have 420hp on my gt3076r, and i would like to have the same power but with better response..
I heard some good things about the borgwarner, but i never see one in germany on a cosworth and have no idea which modification, changes are necessary to fit them..
I know it was some work to fit the gt3076r, i had to make a other oil return, other water connections and oil inlet..

What turbine housing does your GT3076R have on it?
The turbine (or hotside) is what will determine spool characteristics.
The GT3076R could be ordered with .63, .82, and 1.06 AR turbine housings.
The 1.06 being way too big IMO.

I havent a Dynosheet of my car, but i was on enginedyno and had 420HP there.
At the moment im thinking about to change to a 3071 or a Borgwarner, but i dont know the difference at responce and have no idea how tedious it is to mount the borgwarner.
Or i repair my 3076 and swap in the winterbreak..??
Your car revs up to 8.000 rpm??

My old engine made full boost faster than yours with a gt35r .82
But I had fully ported head and cams specc'd to suit the turbo, I honestly think that is what your missing
A cosworth head becomes very restrictive at the power level you are at and you really need at least a inlet cam change, and a decent inlet of some sort
Also what ecu are you running and is it a live mapped car or a chipped standard ecu, all these things will matter at that power

are you saying you had a gt35 on a 2.0 yb making full boost before 4000 rpm ?

8200 so i believe
Mark are you commenting on my car or Brockers?
scoooby slayer is referring to Marks comment

If the EFR makes a big difference at the responce i could thinking about a swap in Winter, but then i need more Infos about them and how to fit..
At saturday i was on the Nordschleife, my setup feels well at the road, but at the racetrack its not funny to wait for the power after the corners.. Here is a Video from Saturday, but i didnt drive attaking because it was really hot, i had 130°C Oiltemp and didnt drive the track for 2-3 years..

Mark Shead has done a few YB's with the BW turbo's. From what i can gather you'd be mad to consider anything but a BW.
They are not cheap but worth it for the better repsonse/ spool. unsure what is required to fit the BW, but i believe they do a internally gated one.
hopefully someone who's got a BW fitted can answer your questions

Hello Brocker,
You have full boost by 4000 rpm. That doesn't seem too out of line for a 400+ HP 2 liter engine.
Did you want full boost by 3000 or lower rpm?
I am not sure full boost by 3000 rpm on a 400+ HP 2 liter is possible?
Maybe someone else can comment.

TBH I cannot see why if you already have a very good setup you would want to change ? Even more so if you haven't even finished getting your current setup working ?!
There is no denying that the BW appears to be a great turbo but its not exactly a direct fit so costs a lot and I really do feel people under estimate the real world performance you can get from a GT or GTX turbo, more power than most can handle and probably more torque than your transmission can take anyway

Cost wise i'd stick with what you have or maybe down size to a GTX3071 to give you better spool up.

I really like my GTX3076 it produces 590bhp and 578 ft/lb of torque, if I had the money i'd like to fit a BW but as said it's the best part of 4 grand with the cost of the turbo, twin scroll manifold and two external wastegates.

I dont know how you reach 4K..
The BW cost only a little more than the GT, i looked for the
EFR7064 with twinscroll and internal WG, bevause i heard the twinscroll spools better
and i would prefer a internal WG. The only negative i see at this setup is the .92AR what could be to big
for good responce?
With T3 manifold its a .83AR, its still bigger then my GT with .72AR, no idea if its still better for the responce?
Ok, i will need a other manifold, no idea how much this cost, i never looked for one,
but i dont know if something else is needed?
Im quit happy with my power, ok maybe i will raise it up to high 400hp
later, but i would like to have better responce with the same power level..

You have to add the cost of a manifold as well as the turbo.
