RonnieJ Posted June 16, 2012 Report Share Posted June 16, 2012 (edited) Some of you know that im going to be making a stock replacement tubular manifold soon (as well as other for guys that want bigger). Well today Jesse (our fabricator) and I got to thinking about the downpipe issue. Before we make the manifolds we were thinking to offer a downpipe is divorced and open dump. We do that now on our Evo stuff. Guys are getting great gains from them and we thought why no start with that. Im going to get some before and after dyno runs once get to making them. I would also need some core exh housings so we can weld the wastegate path shut to keep turn around time as minimal as possible Thoughts, ideas, input, extra exh housings???

One will be 3D machined to taper from the oem goofy pattern to 1.75" pipe and the other cut like oem and stepped to fit 1.75" pipe Initial rapid prototype http://sphotos-h.ak.fbcdn.net/hphotos-ak-ash3/44708_2609134244229_551455762_n.jpg Edited December 12, 2012 by RonnieJ Link to comment Share on other sites More sharing options...
Frenchi934 Posted June 16, 2012 Report Share Posted June 16, 2012 you'll have to weld something into the turbine housing to make this effective. these turbine housing have a path for the gas to travel inside them. When i built my divorced downpipe for my car I had to go in and close that off (it is not like typical mitsu turbine housings) Link to comment Share on other sites More sharing options...

89BananaQuest Posted June 16, 2012 Report Share Posted June 16, 2012 I have two spare housings soon to be 3. I would also be interested in the down pipe! I think its an awsome idea. Link to comment Share on other sites More sharing options...
RonnieJ Posted June 16, 2012 Author Report Share Posted June 16, 2012 Let me know what you want for them and we can work something out Link to comment Share on other sites More sharing options...
nomofwd Posted June 16, 2012 Report Share Posted June 16, 2012 Sounds like an easy way to bolt on better exhaust flow for sure but having ridden in more than a couple cars with open wastegates I would have to wonder how many people would be irritated with the 12a making boost pretty much every time they leave a light! Have you considered a piece that rejoins the exhaust stream further down? That would be the best of both worlds. Of course it's not reinventing the wheel in either way. Props for wanting to provide new parts to the people who desperately want to avoid having to piece things together from other cars or old parts just to make it work. The tubular replacement has me seriously interested. Link to comment Share on other sites More sharing options...
RonnieJ Posted June 16, 2012 Author Report Share Posted June 16, 2012 We can offer it but for the added fab time/cost it would take would drive up price. Im trying to keep costs as low as possible and still offer great products. Im ok with spending a good chunk of change for quality parts but some arent.

nomofwd Posted June 16, 2012 Report Share Posted June 16, 2012 Oh I completely understand that there is extra time, effort and material involved and that would cost more. If it was offered as an option that you were willing to make available I think that would be the best for people who either do not possess the skills or facilities to make the piece the way they would like or would rather pay a little extra and just bolt on exactly what they wanted to accomplish without having to cut, grind and weld something that they just bought new. In my ripe old age of 24 I am finding myself in the group that wouldn't mind paying a little extra to save myself the hassle and have top notch performance. That, and I can't weld worth a damn lol.

creakyjoints Posted June 16, 2012 Report Share Posted June 16, 2012 Speaking of spending a good chunk of change when will you have some headers ready for sale? T3? Divided? Link to comment Share on other sites More sharing options...
RonnieJ Posted June 16, 2012 Author Report Share Posted June 16, 2012 (edited) I can offer the recirc'd option for you guys just trying to keep costs down as much as possible Shouldn't be too much longer.

RonnieJ Posted June 20, 2012 Author Report Share Posted June 20, 2012 Anybody know who sells flanges for the downpie and wastegate portion on the turbo? Link to comment Share on other sites More sharing options...
Lance_S Posted June 20, 2012 Report Share Posted June 20, 2012 Ronnie, I have an EVO 3 S16G. Is the rear of the EVO 3 the same as the one you have pictured? Might be interested. Link to comment Share on other sites More sharing options...
RonnieJ Posted June 20, 2012 Author Report Share Posted June 20, 2012 Lance I think the Evo 3 discharge is 4 bolts not 5. Can you verify that Link to comment Share on other sites More sharing options...
Lance_S Posted June 20, 2012 Report Share Posted June 20, 2012 Yup, your right, 4 bolt. Shoot, no worries. Ask him if he has ever done one or might have one laying around. Link to comment Share on other sites More sharing options...
RonnieJ Posted June 20, 2012 Author Report Share Posted June 20, 2012 I plan on going to a Precision 5858 in a DSM housing. It would be the same flange as yours so im sure we can get something done up for you that will work Link to comment Share on other sites More sharing options...
Lance_S Posted June 20, 2012 Report Share Posted June 20, 2012 Nice. Actually, even with the WG dumping into the DP, this housing moves a lot more air than a stock housing. The WG isn't technically external but it's not internal either. It's a much better housing to work with. Link to comment Share on other sites More sharing options...
speedyquest Posted June 21, 2012 Report Share Posted June 21, 2012 One issue I see with this is going to be that wouldn't each persons hotside be a different diameter? For instance, I have a s16g, so I would imagine that my hotside diameter would be totally different than the guys with a 12a, 14f, small 16g, 18g, etc. How will that be accounted for? If I'm totally wrong and misunderstanding just let me know. Allen Link to comment Share on other sites More sharing options...
RonnieJ Posted June 21, 2012 Author Report Share Posted June 21, 2012 (edited) This would be for a stock framed turbo. Im assuming since you have a 16G you have a DSM flange like Lance. On the flip side of things I have a 20G in a 12A housing that was bored out to fit it Your flange look like this? http://www.treadstoneperformance.com/~treadstone/prod_imgs/img-560-0-large.jpg Edited June 21, 2012 by RonnieJ Link to comment Share on other sites More sharing options...
Lance_S Posted June 21, 2012 Report Share Posted June 21, 2012 Actually you can get all of the sizes in the standard 12 type hotside as long as it's a 5 series. They are the standard 3 bolt. Not many people are running the DSM EVO style housing because they take a custom DP and most don't want to bother with it. So the 12a, 14b, 16g, s16g and 18g all have the same 3 bolt standard hot side housing. Some have to be ground out to fit bigger wheels but most run that standard 3 bolt out.

RonnieJ Posted June 21, 2012 Author Report Share Posted June 21, 2012 Well I have one 12A housing on the way. Ill try and source a DSM housing as well so that way we can offer both Link to comment Share on other sites More sharing options...
speedyquest Posted June 24, 2012 Report Share Posted June 24, 2012 I am running a non dsm hot side. But what I was referring to in my previous post was that if you need to weld up the hole in the hot side and you would be using cores to speed up the turn around time... then wouldn't there be an issue as to whether or not the person has a TD-05, TD-05H, TD-06 etc? Unless you plan on machining each one to each persons setup (which I would imagine would be expensive). I hope that i've explained myself more clearly lol sorry.
