j_jza80 Posted September 2, 2015 Share Posted September 2, 2015 (edited) Just weighing up the pros and cons of various single turbo setups, and I came across this FSR Streetfighter cast manifold. It is based on the SPA cast manifold, but is ported and has a larger V-bad wastegate fitting. It is a much nicer design than most cast manifolds, and you can see that some thought has been given to how it flows. It obviously won't be as good as a true tubular manifold in this regard, but this does have the advantage of price, faster spool and strength. I'm aiming for a high quality, very responsive 550hp using a Garrett GTX3576R Turbo.

Scott Posted September 2, 2015 Share Posted September 2, 2015 That looks like a great bit of kit! Quote Link to comment Share on other sites More sharing options...
mwilkinson Posted September 3, 2015 Share Posted September 3, 2015 V band waste gate fitting is a good thing. I'm running a cast manifold and have no complaints thus far. Quote Link to comment Share on other sites More sharing options...
Big Mark Posted September 3, 2015 Share Posted September 3, 2015 Good find. Just had a read on it http://fsrmotorsports.com/index.php?page=shop.product_details&flypage=flypage.tpl&product_id=29&Itemid=87&vmcchk=1&option=com_virtuemart&Itemid=87 Also, it's in their clearance section so price looks pretty good.

Big Mark Posted September 3, 2015 Share Posted September 3, 2015 Interesting that they talk about running it on stock ECU at 450hp. I thought that when going single you had to either piggy back or go stand-alone. Quote Link to comment Share on other sites More sharing options...
Josh42 Posted September 3, 2015 Share Posted September 3, 2015 The only warning I can offer reference log style manifolds is that the pitch is very deep and doesn't sound like a typical single 2J. Other than that, they spool well and make things simple with regards fitment Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted September 3, 2015 Share Posted September 3, 2015 (edited) Looks like they have tried to address the lack of gasket area, and only a two bolt fixing for the original wastegate. I thin Wes here had issues with the gaskets blowing out on the original wastegate and had a flange welded on. It also seems to have been ported inside the turbo exit, and there looks precious little support for the gasket there. If it's junk material it will warp and blow that gasket out. Remember we are talking turbo manifold pressures as high or higher than boost pressures, at hotter than glowing red temperatures, a real trial for successful sealing. But here lies the rub, the manifold is grey cast iron, I think. Welding to it is tricky. Very tricky. Muffle oven job, special filler material. It will be interesting to see how the weld interface holds up. I am not even sure of the metallurgy of welding what seems stainless to grey cast iron. The OE makers use high nickel content cast iron, Toyota used it for the original, totally trouble free cast manifolds for the twin turbos. They successfully production welded stainless expansion bellows to the high nickel content iron of the 2 manifold sections. Then used oversized holes to allow some movement on the special multi layer stainless steel gaskets. Lots of R&D, with a perfect end result Edited September 3, 2015 by Chris Wilson (see edit history) Quote Link to comment Share on other sites More sharing options...
V8KILR Posted September 3, 2015 Share Posted September 3, 2015 (edited) Lots of guys running this in the USA. Most power I've seen so far on this manifold is 1018whp with a Precision 6870 on a dynojet. http://www.supraforums.com/forum/showthread.php?913673-1018whp-on-a-cast-manifold& I have the SPA manifold and did my own port matching. It is fairly good quality and no problems or complaints so far. I'm only at 490rwkw as running a smaller turbo than previously, but have a Precision 6870 that will go on it after I upgrade the wrist pins.

I thought that when going single you had to either piggy back or go stand-alone. With a piggyback you're still on stock ecu. A lot of standalones are set up as a piggyback as well.

It's a very proven cast manifold with multiple supras using them at over 900 whp. Quote Link to comment Share on other sites More sharing options...

What I meant was that from the write up it sounds like they were talking about running it up to 450hp on the stock ecu only, i.e. no piggy back.

Rob_Mitchell Posted September 3, 2015 Share Posted September 3, 2015 That looks very neat I might even consider one for my build as my power goals ain't far off yours, should make a very responsive street car.

Wez Posted September 3, 2015 Share Posted September 3, 2015 Looks like they have tried to address the lack of gasket area, and only a two bolt fixing for the original wastegate. I thin Wes here had issues with the gaskets blowing out on the original wastegate and had a flange welded on. My original single install was based on a kit from Induction Motorsport which used the Turbonetics log manifold, this had a downward facing wastegate port that was too small and installations suffered with boost creep, Induction Motorsport got round this by adding material and then enlarging the port. This worked fine on the road but for track use I had issues with it spitting the gasket out, I solved this by having the wastegate adapter pipe and manifold faces cleaned and flattened and then welded together Looks like these guys have gone the same route, plus the added bonus of having the port on top to help with supporting the weight of the wastegate.

Chris Wilson Posted September 3, 2015 Share Posted September 3, 2015 Is the manifold pictured in this thread available as *JUST* the manifold? Is the casting from someone else, and they have added the flange, or is it their own casting? Thanks for reminding us of what your setup was Wes. If my concern about welding stainless to cast iron proves unfounded this manifold looks a very viable way to go single with minimal hassle, assuming their downpipe and wastegate exit can be merged (with a flexible bellow of course) and their downpipe does not have clearance issues on a RHD car!

Wez Posted September 3, 2015 Share Posted September 3, 2015 Looks like a SPA manifold with the flange added by themselves. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted September 3, 2015 Share Posted September 3, 2015 OK, thanks Wes, will Google SPA. I will ask my tame welding expert if there's anything trick needed to weld stainless to cast, and if not I may do one or two myself. I fixed up my lovely old TIG the other month, after it blew its output choke, and she's purring again Quote Link to comment Share on other sites More sharing options...

The Turbonetics manifold is still available, now sold by Treadstone. It is highly regarded for a cast mani, bhough it is obviously a more basic design than the SPA/FSR one - - - Updated - - - Looks like a SPA manifold with the flange added by themselves. It is the SPA one, ported out and with a modified wastegate arrangement. It is also available with a wastegate port in the bottom. I prefer the top mount, though more for ease of maintenance than weight concerns. Quote Link to comment Share on other sites More sharing options...

j_jza80 Posted September 3, 2015 Author Share Posted September 3, 2015 I would go with a Wagner tuning manifold if they made one for the 2JZ, but apparently they have no iterest. Their cast manifolds are a work of art. Quote Link to comment Share on other sites More sharing options...
