Hey guys,


I'll be running a 6266 on a stock longblock and wanted to get your take on the V-Band turbine vs. a T3 Twin-Scroll housing.

My goal is for the car to be as streetable as possible on the setup - meaning I'm not out to break any HP records with it. Especially since it's a stock motor.

There's always been a debate on the V-band setup vs. Twin scroll. I currently have the V-band turbine housing. Does anyone have first-hand knowledge and can offer an opinion on which setup will have better response?

Sounds like the only way to make larger turbos fun on the street it require a Twin Scroll setup and a 2.4l.

definitely go with a t4 twinscroll set up with the precision 1.00 a/r. i have this set up and its awesome!

The vband stuff is better in all regards to standard t3. T4 twin scroll is amazing as far as boost response but you have to make sure you have enough hotside to not choke off at high revs. You can't go wrong either way.

I'll be installing my twin scroll 6266 next week with a 1.15 A/R. I'm hoping its going to outspool my last setup (hta3586) but still have some killer top end. Unfortunately pump gas is going to be a limiting factor.

Stuff like this makes me chuckle...wanting a streetable setup, with a stock engine and huge snail. Or wanting big power from huge snails and only wanting to run pumpgas.

T4 twin scroll is my vote and is what I will be running once I get my engine fired up. It's pricey, but well worth the fast spool while maintaining top end power.

Look around, there's many many people boosting stock motors past 600WHP. I had a heavily modified 1G DSM with some mild head work and a maxed-out 3076 making tons of power with no reliability issues on E85. Not sure why this would cause a chuckle - it's common practice

What's your motor specs? Remember I am using a stock longblock with upgraded valve-train.

So the consensus is that the T4 TS housing will spool quicker for me? It makes sense, I'll start looking for one.

Chuckle all you want... I've seen people. Make low 600's on the 6266 on pump gas. Pretty sure that would make for a pretty killer street car... My last setup made 614 on pump/meth.

Because there are smaller options that will have a wider powerband on stock motor and still reach your goals. A 6266 is capable of 750+whp and will shift the powerband to the right to make that 750whp. A 5858 would spool significantly earlier and still be capable of making close to 600whp

Anyone have an idea of how the 1.00 a/r vs. the 1.15 a/r would compare? I tried to PM TwStDeVo about his but he didn't respond. I'm more concerned with spool-up and response rather than max HP and its a street car. My DSM spooled the 3076R around 4300 and it was making around 450-500 and I was pretty happy with that, just to give an idea. I understand this one will be a little less responsive but with the TS I'm hoping the difference won't be much.

Thats exactly why I chuckled. A 6266 TS or not will be nowhere near a 3076. Maybe look into an gtx/hta3076(has more headroom than a standard).

You've contributed absolutely nothing to this thread. Keep chuckling. I understand what I'm getting into - I've probably been running around in 4G63 powered cars longer than you. I just want to know which housing is going to perform better with what I currently have. Which is a 6266. Not a 3076. Not a green, red or black. A 6266.

Let's keep it on topic, boys.

I think he he contributing. And I agree 100% what he is saying.

problem with running big turbos is 99% who have them are really only concerned with the drag power they will get. trying to make a 6266 responsive is quiet pointless really. its gonna be very laggy even with twin scroll. I dont think there is a thread on here with a 6266 6466 TS. TS setups are rare enough as it is. And with so many turbine housing options and manifold builders there is no beaten path out there. it will be really hard to get any solid advice from anyone on which one to use.

bushur doesnt sell any TS stuff period. He has tested them many times. he only sells what works. TS housings hurt horsepower when running high boost.

bottom line. 6266 deserves a forward facing tial vband.

Just because Buschur doesn't run it doesn't mean jack.

TS setups, when done properly, will have a fatter powerband and match the peak power numbers of the single scroll setup. They will have better transient response. They will also tolerate low octane fuel better due to reduced reversion.

The downfalls of TS is weight, complexity, and packaging. If those things don't matter to you TS is the way to go with anything bigger than a GT28. The only time I would argue for single scroll is if you have a turbo that meets your spool goal and you are maxing it out on airflow using good fuel. Even then, the car better be a stripped down race car to warrant the concern over weight and complexity.
