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

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.

cool cool no i have an h23. anyone have an idea of what turbo size i should use on this engine?

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.

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.

Re: Twin scroll turbo
 

Youve got an h23 so unless it's an obd2 h23vtec then you can use the manifold and turbo from an 04 evo. It's a big 16g and I have one on my accord. It's taken some modification to make it work but I'm telling you it's worth it. And you can get a good used turbo and manifold off of ebay for like 250-300 range from an evo guy thats doing a 20g upgrade.

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.

yeah i know i have an evo mani on my car right now but its not that one and i would rather not have to change over to the mistu turbos ( i just dont like them) i have a t3 mani and still want to be able to use it.
heres my engine bay

Re: Twin scroll turbo
 

You have a lot more then a twin scroll turbo manifold to worry about. :y

Re: Twin scroll turbo
 

you're not specific enough, i can build 20 different sizes of t3/t4 57 trim, some too small, some too large, and some just right for the h23. turbine trim and a/r are the most important specs. t04e 57 trim is the one size fits all compressor that everybody know about because it's the only one that is sold all assembled by garrett and that ebay peddlers can push on the market without having to build them. 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.

I'd listen to this man. He should be paid to speak :6

Re: Twin scroll turbo
 

Like what ive run this setup for over a year with no issues other than the turbo is to small.

when it comes to all those numbers about trim and stuff i am clueless, im pretty much here to just learn what will work best for my car. the turbo that is on the car right now is a garret saab turbo they say its like a 14b its ar is 48 and thats all i know about it, i got it off another accord.

You need to buy an msd delete kit. They rape your timing and tear up ignitors . :3

Re: Twin scroll turbo
 

How come I don't get sackriders like Blaast? ;)

Re: Twin scroll turbo
 

please tell me more about this msd delete kit, i have never heard of it before.

Re: Twin scroll turbo
 

For $100 American I'll come to your house and take all the msd ---- off your car and return it to stock.

Re: Twin scroll turbo
 

bahahahahahahahahhaha .. silly noobs

Re: Twin scroll turbo
 

sell me your msd

Re: Twin scroll turbo
 

duh sorry it was late when i reponded im usually not so dumb. usually but then i am a blonde. i dont want to take my msd off, i like it more spark better reaction with the car. no spark blow out, why wouldnt i want to run the msd?

Re: Twin scroll turbo
 

msd makes good ---- for domestics, not so much for hondas

stock spark on a honda is perfectly fine until you get into very high hp levels. MSD just complicates ---- and it is not needed

Re: Twin scroll turbo
 

what kind of complications might it cause?

Re: Twin scroll turbo
 

itll replace an ignitor perfectly, but using in conjunction with an ignitor = bad

Re: Twin scroll turbo
 

explain that please.
I am stuck to 10 psi on my prelude, we had to stop tuning because of a surging problem that happens around 4000 rpm and when it does it, the RPM needle is jumping all over the places. i got a new ignitor from honda, the guys there told me that it's certainly not the ignitor because they either work or don't and apparently can't cause an on & off problem like that according to them.
i do have MSD 6a+ coil. Tried to bypass them completely and the problem remains. Changed plugs, wires, ECU, conversion harness, distrib rotor, checked all connections.... the problem doesn't go.

Re: Twin scroll turbo
 

msd ignitions put out big voltage and amperage to stock coils/ignitors, youre lucky to make 5000 miles before itll either eat the coil/ignitor i replaced my $400 to replace ignitor/coil with a msd 6al, accel coil, and 22re dizzy pickup coil (stronger magnetic fields, carb pickup doesnt have the oomph for msd to realize its triggering)

n/a i can gap plugs out to .045" at 13.5"1, .040 in boost. if you've ever been shocked by a coil by accident, wait till you get hit with msd and feels like you got struck by lightning. definitely the way to go if you need huge fat spark though.

i really doubt you can delete the honda dizzy internals, but here's the wiring for honda to msd

Re: Twin scroll turbo
 

but did i understand that with a 6al and blaster coil you can remove the honda ignitor?

Re: Twin scroll turbo
 

i promise you i have over 10,000 miles on mine with no troubles. im not gonna bother with it, if it isnt broke dont fix it. i need to worry about the next turbo i get, not the msd.
