slydog 7,873 Posted September 14, 2013 Lol @ telling stories. <br /><br />Like I said, wastegate off the turbine housing is the best form of boost control and it's not that hard to do, for someone half competent anyways. Not overly hard to weld just as explained have to pre heat the cast item before welding.Fixed a few camping cook pots in this manner that are still fine today and they get many many heat cycles.The placement on the turbine would be ideal aswell so I would buy a new 1 as above or weld the housing as explained.

The gate on housing will work fine, no dramas. But comparing your bush tucker pot which hits a max of 280 degrees or so to a turbine housing which can see 1000 degrees and with stupid pressures is like saying .....well.... it's just not like saying anything sensible at all. Do the world a favour and stop chiming in on shit you have no clue about. Your cook pot is not a turbine housing. All this false information is not helpful. It will work but welding a pot and welding a turbine housing is no where near the friggen same. Stick to your crossflows. Share this post Link to post Share on other sites
slydog 7,873 Posted September 15, 2013 So your calling Millan and Charles idiot's too cos they recommend it and Charles has actually done it or do you mean just me? Beyond that I infact know how too and do weld my own stuff (just like Charles and Millan/Branko do) or you can check my build thread that I actually do not sub out or pay for so maybe I do have more idea about this than you can accept.Besides having welded for oh about just over about 16 odd years I have welded up cast exhaust manifolds before with no failures or issues but perhaps you can show us all the ones you have done to show how wrong everyone else is and why your the worlds expert on the matter seeing as you don't have the hardware to do anything mentioned above.

PRO250 1,506 Posted September 15, 2013 good read thismy cortina has a cast manifold on it and the wastgate on 1 side of the manifold its on 18 psi and makes 250killer wasps on a almost stock engine so they must work ok it does boost creep a little butbye wes Share this post Link to post Share on other sites
matt_lamb_160 252 Posted September 16, 2013 No doubt it would "work" as the top of the collector is open, but I could see that it was less than ideal and was after ideas on how to fix it which I have received. The cast welding is not a major issue, I can use cast steam pipe and Ni rods (pre-heat does not need to be super hot), but then welding my s/steel v-band flange to cast I am not sure? Some have suggested "buttering" the cast with Ni and then welding the s/steel to the Ni??? A good manifold that already had a v-band flange to suit a 44mm Tial wasgate would be nice .

I migged SS to Cast using Nirod years ago, not on an exhaust housing (lining a cast pump) but principal applies regardless."Buttering" does work and gives the weld something to "bite" onto, join some scrap pieces first to perfect you technique if you have doubts, but it definitely can be done.

matt_lamb_160 252 Posted September 26, 2013 Thanks mate. Now thinking of having a mild steel piece of pipe in between to position the wastegate to where I want it. Will try Nicore 55 rods to joint cast to mild and Weldalls (because we have them) for mild to s/steel. Share this post Link to post Share on other sites
PSI_LTD 37 Posted September 28, 2013 1. Avoid having extra flange joints pre turbine... so no gate adapter plates. 2. Reallistically u should have the gate either off both branches, if a log manifold, one off to the side is fine. The turbine option is ok, just ensure its welded right. lol at the pissing contest though.. 2 Thom and XFute-1JZsoarer reacted to this Share this post Link to post Share on other sites
matt_lamb_160 252 Posted September 28, 2013 Thanks mate, agreed extra flanges are asking for leaks. Looking at making a manifold (low mount high gate) now or getting a good cast log one. KLR250's old low mount mani had the wastegate between number 5 and 6. Mine will be in the centre but it just shows what can 'work' (on logs at least).

rswepn 66 Posted September 29, 2013 Here is a split pulse manifold with a gate off a housing i did recently. Pics arent the best but thats all i got at the moment. Share this post Link to post Share on other sites

ricktewagon 39 Posted January 4, 2014 Cool thread...... What do you guys think of the positioning on THIS manifold? Its basically a stocker-style that runs straight to wastegate from original exhaust port, with turbo on the side. Running 16lb boost & no BOV. See if you can make it out from the pics. I can't seem to make them big? Share this post Link to post Share on other sites
XPT 673 Posted January 5, 2014 Hey mate, use photobucket and links etc to upload full size pics. A long shot of the setup would help. From what I can tell it looks like you've cut a hole and welded a turbo flange onto a stock cast iron exhaust manifold and used the old exhaust outlet as a wastegate feed. Correct ? I'm not an absolute messiah of turbo manifolds but I have made/modified a couple that turned out ok. That setup is crude looking and probably not absolutely ideal for power with all of the sharp angles etc. However, if it does control boost (you said running 16psi), you're happy with the spool up and overall power, it probably works fine.

matt_lamb_160 252 Posted January 7, 2014 Wastegate position is good, but the entry to the turbo may be questionable. Share this post Link to post Share on other sites
ricktewagon 39 Posted January 8, 2014 Yeah turbo position is okay but could be better. Definently will need an exhaust manifold upgrade at some stage regardless Share this post Link to post Share on other sites
PRO250 1,506 Posted January 10, 2014 seems to work but, 250killer wasps under 4000rpm speaks for itself Share this post Link to post Share on other sites
ricktewagon 39 Posted October 30, 2014 Just thought I'd share a couple pics of my setup while my exhaust Manifold is off. Let me know your opinions. Share this post Link to post Share on other sites
gerg 10,871 Posted October 30, 2014 Yeah looks ok to me, the stock iron manifold might be a bit weak in some spots, time will tell. Turbos are more about pressure than flow and I've seen some factory diesel ones that look like shit (literally a log manifold with a flange) but they work. VL turbo ones were nothing to look at but did the job. Share this post Link to post Share on other sites
PRO250 1,506 Posted October 30, 2014 Is it a stock manifold with a J pipe?if so can you take some pictures of how its done? Share this post Link to post Share on other sites
ricktewagon 39 Posted October 30, 2014 Yeah will do in the next day or two, the stock exhaust connection just goes straight to the wastegate and there is a flange on the side for the turbo. I should have turned those pics around to....Heres a couple more pics. 1 Mixalis reacted to this Share this post Link to post Share on other sites

ricktewagon 39 Posted October 31, 2014 After the engine was in the car I basically bolted the Turbo on to the Manifold & gave it to the exhaust shop. Told them I needed Starter Motor access without pulling it out & showed them where to put the Wastegate. 1700 Bucks later...This is the first time Ive actually had the whole piece out as is together.
