Ok so twinscrolls are the new hot topic and are amazing based on firsthand account. I am looking for a GT3076R kit, but I need to decide between:

1. One of the many standard proven GT3076R turbokits on the market + 2.3 stroker

OR

2. Full-Race twinscroll GT3076R kit


I am interested in spool and part-throttle responsiveness. Car is an 03 Evo, mostly driven on the street with some circuit and autocross. Not so much drag. I've heard the twinscroll kits described as "having the spool of a 2.3 on a 2.0", but if it came down to it....what would be better? Is it better to spool quicker due to more displacement, or thru turbo and manifold design?

Any ideas or suggestions would be appreciated thanks.

 

Do the 30R+ stroker. You get all the benefits if not better results with that than the 2.0 and 30R, plus you have a built motor which will take 30 psi much better than stock internals.

Also that 2.3 can also spool up any other larger turbo quicker than a twin scroll.

My 2.3+30R made 490 480 at 30 psi on c16, peak tq at 4800 rpms.

tru but you can rev the 2.0 to 9k as opposed to 8k

 

True, but how many turbos make power after 8K. The GT3076 doesn't on a Evo motor, so I would say go with the stroker.

More torque is never a bad thing....

 

ATP 3037s kit making 472whp 426tq with pump 93 octane, 100% meth, and 25 psi. was told by ICS with c16 and about 30 psi the car would see about 550whp.

 

He made no mention of a built 2.0 so the answer is "No".

 

Yeah the fullrace kit would hypothetically go on a stock 2.0

 

You doing some internal work as well should you go Twin?

 

You was told a lie.

Exactly what he said

 

also I'm thinking to buy twin 3076r + tomei 2.2 ... my goal is = 510 whp

( aem ems+ meth + fullrace intake manifold + throttle body )

sounds good...maybe I will reached that power at 30 psi ...

 

we can happily supply you a single scroll 3076R, in fact after some test results we just saw, im confident our single scroll setups will outperform most of the other "standard" setups out there.

We've made some of the best single scroll setups for years, very few single scroll turbo kits will outperform ours. Our twinscroll kits are simply next level -- they are capable of more performance and offer tremendous versatility You can run a single scroll turbo on our twinscroll setup and it will be an efficient single scroll. You can run a twinscroll turbo on our twinscroll setup and get the benefits/gains of the twinscroll. You can run a twinscroll 30R, or 35R, and there are even some options that should be available in a few months for twinscroll 50 trims.

if you are interested in part-throttle response, twinscroll is what you want. A stroker will have a fat powerband, but response is ultimately dictated by turbine efficiency, and that is where twinscroll excels (because the turbine has to power the compressor)


its best to have an efficient turbo and manifold design, in conjunction with an efficient intercooler and charge pipe layout, along with a great fuel system and good tune, along with a good bottom end... it ALL matters. everything works together as a system, you cant pick and choose parts, you need to integrate them to work together.


The best thing you could probably do is ask the people who have experience with the twinscroll 30R.

 

well only one way to find out

and i think ur just mad that my ATP kit is making as much as it is with only 25 psi (1.7bar actually)

 

The difference between 25 and 30 psi on a 30R is a lot less than 25 and 30 on a bigger turbo.

Mine/your 30R will start to run out of steam/efficiency at the RPMS where more power would be made. You will increase tq a lot and HP by a little when you crank up the boost from where you are now.

Go and prove me wrong please

well i thought it was high as well but i can see another 30whp with 5more psi and c16. its funny too because when i was there ready to pick the car up, they were very impressed with it. they were tuning my car and a 35r then same night and they said it pulled just as hard as the 35r did. the 35r had more hp but less tq. my area under the curve was a lot meatier as well. i was surprised.
