Your posts are all conjecture. If the T3 housing was the restriction with a .75 a/r then why would they offer it in a 1.25 a/r?
Trust me if you ran a 1.25 a/r twin scroll T3 housing on this turbo it would make way more power than any MHI housing turbo at the same boost levels. The exhaust wheel is bigger which helps out downstream.
Besides if your that worried about it the T4 hotsides are even cheaper than the T3's for this turbo. Since he doesn't even have a manifold yet just get the T4 manifold.
It is all conjecture. I don't think anyone has ever had any T3 twinscroll results on the Evo. But I don't see how going smaller on the manifold outlet could be good.

His goal is 450~500 horsepower. T4 will reduce exhaust velocities which is bad for scroll, and is way overkill. That's why a T4 vs. T3 same a/r scroll different. DSM boys have run T3 twin scroll setups and it's proven.

You have a very rough grasp of how turbine housings work. Educate yourself and come back. T4 divided is the way to go.

Ignorant people make my job hard, that's my new slogan. You have a very rough grasp on reality newbie.
If you knew you would know that all S200 turbos T4 hotsides actually are T3 cross sections with a T4 flange. When running a T4 twin scroll manifold you need to open up the S200 hotside to match. See pics. Why not just run the custom T3 hotside no porting required.
Mr peepers has an HX35 T3 twin scroll that makes 500hp @30psi and is at full boost by 3500 rpm on a 2.0 dsm, 264 cams. That's spooling faster than a single scroll .55 a/r BEP housing. HX35 has almost the same exact specs as the s257sx-e. So tell me it don't work.

Here ya go...
T3 twin scroll with HX35 $250~350 on eBay add $75 rebuild kit and your ready for action. May I also remind you that this turbo older technology, I'm sure the SX-E turbos are better spooling and higher flowing with a wider pressure map. Comp. Inducer is 57mm on both the sxe and the holset, except the holset has a cast wheel which is heavy and flows less. Both are journal bearing. VS
FP red at same exact boost levels tuned by the best evo tuner there is on a 2.3l
Dam I think the FP red just got its a$$ handed to it by an 20 year old technology, cast wheel, journal bearing POS off of ebay! DSM boys know the advantages of twin scroll maybe you should educate yourself better.....just sayin. Wholly crap that's a 2.3l red setup just noticed!!!!!!! 2.0l with faster spool than a 2.3l!!!! Checkmate

The HX ripped quick, but nosed over sooner.
I think the 12cm² T3 turbine housing created too much back pressure.
Torque falls off terribly for a 2.0L, almost looks like a 2.3L.
It would've been nice to see the boost plot from the HX35 run.
However, 2winscroll is 100% spot on.
The S200 is clearly a T3 volute in a T4 flange, which I think is *****in!
I'm very interested in running this turbo on the road course behind a LR2.4L, but then I'm torn because I want a big turbo I can throw on and light up local V8's, so I'm looking at the S362SXE too.
Probably end up getting both for less than the cost of new BB stuff, plus the BW stuff is oil cooled only, so less to deal with there as well.
****Edit****
I just reread the post above, the Red is on an Evo 2.3L...

I see the point you're making 2winscroll, but the FP red vs Holset graphs you just posted both make 400wtq at around the same rpm, (3800ish). The red also makes a few HP, more torque, and its making more torque at 7k rpms, as well as revving to 8k. I would like to find out if that red is a signle or twin scroll, and did the car have mivec or not. Also, what fuel are both cars on?
Now you guys are splitting hairs. 2.3l vs 2.0l looks to me like torque at 7000rpm is only about 15~20 ft lbs. less. 2.0 spools quicker and we are comparing it to a 2.3l that's why you see more torque early in the run from the FP red. Top end power are within 200 rpm how much closer of a comparison do you want?
That FP red ran out of injector. Could have easily made 600whp+
I'm not sure what the HX35 is fully capable of, but that FP red for sure had 100whp left in it.
HX35 has a cast wheel so no it can't make 600hp. The S257sx-e has a billet wheel that's good to 650, so someone needs to buy one and test it out. Until then I guess we will never know 4 sure.

I will be buying a S257SX-E with the 1.22 A/R twinscroll T4 hotside, but first I have to pay for my 93rwhp Yamaha Banshee motor that I just had built.
