Is it possible to make a standard T3 flange manifold into a divided?

[Tiki2777]

I was wondering, since I am looking into a full twinscroll HX35 setup (and i am looking for a nice and cheap manifold... he he haha...), is it possible to weld a plate into the turbo T3 flange to get a cheap divided t3 setup? Has anyone done this? Is this possible? Thanks in advance .

Just welding in a plate probably wouldn't work as the whole point of a twin scroll setup is to keep the pulses separate. The collector would probably have to be setup perfectly with still some additional modification to keep the runners divided or you'd have to heavily modify the collector to make them properly divided.

How cheap are you looking? Have you talked to redjack racing or Dark performance.

Like dirt cheap . Redjack is the cheapest, but ive never heard of dark. If i have to I'll get my friend to help me make my own.

Don't you think it would be possible as long as you kept the divider all the way through to the pairs of runners?

Anything is possible. All depends on how much time and effort you want to put into it and what you're starting with. I can't really say without know what you're starting with and what fab skills you have.

Keep in mind you'll also have to add either two wastegate tubes (one off each side of the collector) or a split single gate tube that merges both pulses at the very end.

For the wastegate side of things, I was hoping that the stock internally gated turbine housing on the 35 would be good enough (for the time being anyways). I started to think about what you said about the exhaust pulses with the runners, and, honestly, if I was to go ahead with either welding a divider in or making a manifold myself, what kind of manifold would either be less of a mess to work with or what kind of angles should i look for or try to make on the collector/runner side of things? I hope that makes sense.

Does the 35r have a divided exhaust housing? I can't say I've heard of one that does. But there may be that I don't know about.

I really don't know how an internal gate will work as I would think that'd negate the purpose seeing as it wouldn't be divided. That seems like it'd be the same as running an open T3 manifold.

No idea on what to start with. I don't take the "do it as cheap as possible" path so if it was me, I'd either start with something twin scroll and be done or do your research and talk to people on what it takes to make you own if you want to go that route.

Oh my bad , I was talking about the HX35, you must of missed that over my original post but no big d. I have no idea how exactly it works but i guess it does .

I try to stay away from cheap stuff as well, but the dsmtuners member Mr.Peepers inspired me to build my own, and he has had success with his setup. (he even mig'd his whole manifold)

Yes, the HX35 has a twin scroll housing. I forgot you had mentioned that, and then got confused on which turbo you were talking about.

Just check out pictures of his and you should be able to replicate it. You'll have to determine what size tubing you want to use, how to mock it up and make sure placement is correct for all clearances (water pipe, block, front roll stop, radiator/fans, alternator, power steering pump, etc.), figure out how to get runners to match head ports in size/shape (since tubing is round), location of wastegate, how to keep it compact but not too much that you can't weld, make sure runners are as equal length as possible, etc. His design will give you the basics but you'll have to do a lot of work on your own to get it made.

Yea...

I don't know if that's a "Yea, I know what needs to be done" or if it's a "Yea, that's a lot of stuff to consider"

Building a manifold isn't an easy task. But if you want to do it, I'd be interested to see your approach and how it comes out.

There are two ways to do this...cheap-out on the turbo and buy a twin-scroll manifold, or cheap-out on the manifold and put money into the turbo by purchasing a turbine housing that will fit a DSM manifold.

If you cheap-out on both and use a single-scroll manifold on the factory twin-scroll Holset turbine housing, you'll have a super-laggy turbo that you'll be quite disappoined with. This is how so many guys end up bashing certain turbos that are proven to work for others...improper setup.

Yea I'll be sure to take plenty of pics and either add it to my build thread or make a write up on it.

And that's a "yea" as in, "this is gonna be a pain in the ass" .

I've already decided against a single scroll, and a BEP housing would not flow enough to max out the 7 blade (i haven't decided if maxing it out would be a good idea or not yet). A twinscroll setup would be great for the street. Open T3 to Divided is a horrible idea.
