Twin scroll turbo
i have been looking at a turbo that i like but it is a twin scroll and i really didnt want to change my mani to the twin scroll mani. so my question is can i use a twin scroll turbo on a non twin scroll mani and will there be that big of a difference?
Thanks

Re: Twin scroll turbo
You can sharpen the dividing wall like a knife edge and use it on a non twin scroll setup without any downside but I doubt it will perform any better than a single scroll. Or, if it'S off a huge truck with 1.15 or 1.32 a/r turbne and your engine a 4 cyl with 130-160hp, you can make a block off plate to send all the exhaust flow into only ONE of the 2 holes to accelerate spool up a little.

Re: Twin scroll turbo
h23, that's 160 HP right?
You don'T want a T4 turbine on this engine. Unless it's a rare one with low a/r under .60 and a small wheel like N or O trim.
Ideally, for quick response, you want a stage 1 t3/T4 with 0.63 turbine. concerning the compressor, most of the small to medium T4 ones will work. I suggest a T04B S or 54 trim or a T04e 46 trim. I am almost certain the compressor side of your T4 would be worth a try. If you post a picture of it, we can tell you what it is and if it's appropriate or not.

Re: Twin scroll turbo
i have a t3 saab turbo at the moment and its way to small for the car. yes the h23 is 160hp 2.3L i was thinking about the t3/t4 57 trim but alot of the b series run that one and i am afraid it will run out of steam in the higher rpms. i am not looking to make huge power around 250-300 would be plenty.

here's a pic of it in my car you have to move the alternator up but it's worth it the thing spools really fast and makes great power at really low boost.

But yeah... t04e 57 will work on the H23. turbine wise it's eaither stage 3 .48 or .63 or stage 1 .63 or even .82 IMO.
