As stated the GTX3071 will spool quicker than your GT3076 but flows more air. The GT3076 is a ~54 lb/min turbo the GTX3071 is ~56 lb/min turbo.

the manifold and turbo together, i would say yes, the downpipe would require modification, but the downpipe is not the manifold.

also i don't remember anyone even trying to put a 7064 on their AGP manifold. and from what i remember of the dimensions, the compressor housing should have plenty of clearence, it is the turbien housing with the Vband that is long and will require the downpipe be modified/fabricated.

I'd like to see it done on an SRT and see what issues come up. I wonder if the built in boost control solenoid and WGA would work on pcm controlled boost as well. I wasn't even thinking about the exhaust down pipe not fitting, and now that I'm actually thinking about it, the hot side pipe would need some type of adapter as well. This is not a swap in, bolt in type thing, but if it fits, it's an option.

the WGA solenoid that comes with the turbo operates @ 60hz frequency i beleive as opposed to the 32hz the stock solenoid does, so the PCM would need a rescale.

but if your going with a bigger turbo your going to need a tune anyway so......

I see this new gtx 3576r spools faster and makes more power.
Looks like a kick ass turbo in a .63, I'm thinking hard about it!

the efr 7064 spools faster than both with 560hp capacity................ and it has the best transient boost response of any turbo its size from the super light weight TiAl turbine wheel... the GTX turbo are over priced for what they are your better off with a bullseye power BWM s252 which is 520 whp capacity
if you want the best money can buy curently its made by borgwarner...

Sold My Soul for a Neon

TIRED OF YOUR EGO HARD DATA IS MORE IMPORTANT AND USEFUL TO OTHERS SEEKING KNOWLEDGE AND THOES WANTING TO ADVANCE THE PLATFORM
DONT GET STUCK ON PRECISION TURBOS AND BWS THEY ARE NOT THE END ALL........ OTHER GREAT OPTIONS EXIST DO SOME RESEARCH DON'T BE A SHEEP

Please post Dyno sheets for a turbo on an SRT4 that makes a better powerband or has a better spool than my GTX3071R. Everyone is happy to quote advertised numbers, but I haven't seen anything posted to back it up!

Not saying something doesn't exist.... But I haven't seen it!

My info is linked in post #4.

That 7064 is the same price as the GTX3576r $1700.
But the GTX3576r can make 750hp, I agree It's $$ but the Reg 3576r is cheaper spools alittle slower.

That is very nice, and got me looking into the GTX series!

Just make sure you match the parts to the desired outcome. It's always funny when people wonder why thier "same" turbo doesn't put down the same numbers on thier log manifold with a T3/T4 and a factory intercooler....

~59-60lb/min compressor side, with a gt35r turbine wheel...

Not a chance it will make 750hp... GTX3582, or HTA3582 will, on complete kill mode.

That's the best powerband I've ever seen on an srt.

On the flip side...for a street car, that screams carnage to me. 650tq at 4500? Death to transmission parts (and your bottom end too if you aren't careful with your tune!), lol.

My GTX3076r is the business (so was my HTA30 when I had it). Garrett did well with the GTX turbos.

Thanks! Nigel put in a very safe tune... He knows my car and what I need.

Already spun all the teeth off both sides of fourth gear... Now I carry a spare gearset to the track...just in case. LOL

With that tq curve, I believe it. Are you able to utilize all that power, and put it down on your tire setup, or was this just a dyno only run?

The crazy thing is...you could easily run 32-35psi...and maybe not have much steam left hp wise, but the tq would be ridiculous.
