I wanna bring this back from the dead years later, anyone tried it? If not, I'm considering trying it just for shits and gigs.

Heres my idea and I'm all ears for any opinions good or bad.

Two paralell 14b or 16g turbos,cyl 1&2 into one turbo,cyl 3&4 into the other turbo (open scroll turbos)

Or a set of small twinscroll turbos (not sure what the smallest ts t3 turbo available is) , 1&2
Go into each twin volute of one turbo, and 3&4 will go into each twin volute, so basically each volute will habe it's own cyl pulse. Exhaust would be merged into a single pipe, charge piping merged into a single pipe, and routed their normal ways.

Only wondering about this cause ive never seen it done on a 4 cyl. Curious to make something up to try. I know compounds habe been done, but this seems a little wild not to try before i do outlaw style drag setup with a xona 95•68

Mazda used a sequential back in the day ant that was only a 1.3 liter, well 2.6 when compared to a 4 stroke engine. Exhaust and boost pipes fed the larger one and finally the engine exhaust. The gate on the smaller one would have to feed the large one as well to maintain exhaust flow. Could work but waste of time and money if you ask me. If your worried about down low lag then spray a little 30-50 shot and call it a day. Liquid torque would do the same and less complicated.

I'm talking about a paralell setup. And I'd fab it all. Wouldnt be more then the cost of two 14b's and some of my normal materials.im not worried about lag or performance, i just wanna try it to try it and see what comes of it my car is a dedicated drag car/weekend warrior, kinda wanted to try something fun and unheard of before strapping down the single 67mm and going to the normal planned route

Then screw it, if your doing it and its not costing much, then in the name of car science do it. Have not seen many if not at all twin turbo 4 bangers.

It's possible. Darrell Cox Racing did this with SRT-4s; used 2 stock turbos hacked together for a twin turbo 4 cylinder. A big single turbo was cheaper, more powerful, and farrr less complicated.

If be interested to see it, but I don't think it'd be effective. Seems like alot of the exhaust energy would be diluted, unless you used gt15-gt17s, which wouldn't make more than 275-300 hp.

There was a pic from way back that had 2 14bs/t25s in a twin setup on a 4g63, I'm just too lazy to go find it. It wasn't pretty, but it was done at least. I have no doubt you could make a beautiful setup for it @Archer Fabrications

No dount it's easier to big single. I'm just curious how it would do haha it's not something I'd offer as a production piece. Just one of those things to get some what the f*cks and actually work to some extent.

I totally agree, if I had the time and expendable parts/income, id love to see one working. If you do attempt it, make a thread, if love to follow along with it. If i get the time and scratch, I may rebuild a couple of my 14bs and give it a shade-tree-try.

If you've got the itch to fab something weird and learn new shit, I still think compounds is the way to go. It's at least been shown to work well in many cases (many others have not succeeded). Yesterday Nick Stack and I were in the IFO Outlaw final round both with compound turbo setups running low 5s in the 8th (low 8 quarters), spooling on autos with no nitrous. I still learn new things every time I take the car out, and I've been doing it since 2009.

On the other hand, if you really want to try twins, I say go for it. What is there to lose. You're bound to learn more than you pay in time and parts.

Not against conpounds at all, I'd like to try that too. Let me know if you guys need a redo on the hot piping

If you have the money and ability to fabricate the setup why not just try it and see how it goes? Unless you are looking for advice on how to go forward with it, then why not just try? Personally I don't think twin scroll turbos would work better, if anything my guess is they would be a bit worse because there wouldn't be enough pressure at one time to get the turbo spooling. I would imagine it would just cause the gas to flow through the fins.

In my mind it seems like a twin scroll would be like a continuous slight breeze to try to spin a fan vs using two pulses at the same time to give it several strong gusts. But I could be wrong, turbos do move pretty freely. I'm just not sure it would have enough pressure to get it to spool up.

It is actually a thought provoking idea. It would be a very cool experiment to see how it works out. Personally if I had the time, skills, and resources to do something like this I probably would. It would make a very fun youtube video.

Yup, I get the benefits of both worlds in a twin-scroll setup, less lag and ridiculous top-end power. I spool around 20 psi at around 4400-4500 rpm and it's very capable of breaking at least 800 HP in the top-end.

Where did you get the manifold? I’m trying to twin turbo my 96 eclipse and I haven’t been able to find a manifold for it

So i'm just curious but has it ever been tried a twin turbo set-up for a dsm?
You think the engine would handle it? And yes its only a 4 cylinder which would probably be useless but how many people can say they have a twin turbo'ed dsm
maybe something new to try if you got money to blow
inputs please

So, technically, you can do a twin turbo setup as there are a couple of people out there who have done it before and the two I can think of off the top of my head is one guy who did a twin turbo setup on a Beta 2 2.0L Hyundai Tiburon that you can find online (380hp Tiburon or something like that) and there's the Twin Turbo K20 MR2 made by Boostedboiz YouTube channel.) As far as I know there was also some twin turbo 4G's as well out there that have shown it's been done previously so it can indeed work but it'll also take some work to get it done as well as money and time as well.

I mean, you would need to get some things made up for the intake manifold to split between two of the cylinder banks to use both turbos and have two individual flanges for each turbo to sit on top of which also includes they both may need their own wastegates for each and many more things but I'm not too sure on that specifically as there's a bunch of other stuff involved with it too and it would involve lots of custom stuff to be made to get it to work. But it is indeed possible.

Personally, it's just simpler and more cost effective to run a big single over the twin turbo setup simply because it's just already been done plenty of times over in the past to the current present, it's known to be effective enough to get the job done too and the only reason you'd ever need to go twin is just for the brownie points on the fact that you can say you did it when no one else really has along with a somewhat unique setup and that's about it. I vote, keep it single as a pringle and send it.
