arnout Posted October 29, 2004 Author Share Posted October 29, 2004 Ok back on topic. About the manifold. Not much news this week. The manifold has been here for the whole week and it has been picked up a few hours ago to go back to the company that makes them to drill the holes and make the threads for the bolts. We had some issues with finding a correct gasket. The gasket I planned to use was from an austin healey or something. It was an exhaust gasket but it can't stand the high temperatures in a turbocharged car. My quest for a new gasket continued and it had to be a three bolt with the correct holes and PCD for the bolts, as the manifold was already cast. We ran into a gasket from a volvo, which had a hole slightly bigger than the 50mm we designed for the manifold. The gasket had the same design as the 2 bolt gaskets from turbonetics, only it is a three bolt. Here you can see a picture of it: http://www.supras.nl/iB_html/uploads/post-2-50743-mini_DSCF0001.JPG We also test fitted the gasket on the newly made manifold: http://www.supras.nl/iB_html/uploads/post-2-50785-mini_DSCF0004.JPG So long everything is progressing pretty nicely. We haven't test fitted the manifold on a car yet. I don't have a manifold with the correct bolt-holes. I only have this unit in the picture and there are no holes in, nor is it resurfaced etc.etc. I hope to have a unit next week which is 'finished'. We designed the flange slightly further away from the manifold so even the really big compressor housings (like the T61 A/R 1.35 or the Greddy T88) will fit the manifold without any issues. I know the turbo is pretty close to the struttowerbrace, but I don't expect big problems there. In case we will have these, we need to adjust the design slightly.

eyefi Posted October 29, 2004 Share Posted October 29, 2004 how about making the manifold twin entry, keeping the pulses from 1/2/3 separate from 4/5/6. if u fit a twin entry turbo it could b quite beneficial. would it hurt the performance of a single entry turbo though?

arnout Posted November 20, 2004 Author Share Posted November 20, 2004 here is an update I've put on moronforums: ok guys. We have more news. We test fitted the manifold on a 2jz head to make some pictures. Here you see the newly designed manifold fitted: http://www.solidus-ict-2.demon.nl/mini-DSCF2014.JPG As you can see in the following picture the wastegate flange is about the same direction as the turbonetics 2 bolt flange. We use a 3 bolt flange which is pretty universal and for which you can get various gaskets (we used one for a volvo turbo) http://www.solidus-ict-2.demon.nl/mini-DSCF2019.JPG One of the annoying problems we had with the turbonetics manifold was that the two inner bolts (near to the wastegate port) where not reachable with a ring spanner, only with an open-end one. As you can see in the following picture this problem was solved in our design as well: http://www.solidus-ict-2.demon.nl/mini-IMGP0808.JPG On the next picture you see the port matching of the manifold on the head. The port matching is almost perfect, so little or no turbulence is generated due to bad matching: http://www.solidus-ict-2.demon.nl/mini-DSCF2008.JPG Next picture shows the massive wastegate hole, which is a three-bolt flange also, so you have less chance of leaking or blown out gaskets. Also the surface is mirror finish, like all surfaces on the manifold. http://www.solidus-ict-2.demon.nl/mini-DSCF2012.JPG Next we checked the fitment of the manifold with an SP67 turbo on my own car. My car is a 2jz equipped mark 3 supra, so the engine bay has considarably less space than a mkIV supra. It does have to fit my own car, cause originally I decided to design this manifold for my own car. Here is the first picture: http://www.solidus-ict-2.demon.nl/mini-DSCF2021.JPG The Cusco front strutbar is not bolted down, but from the picture it's pretty obvious the turbo will never hit the strutbar. On the next picture you can see the spacing between the turbo and the struttower. As you can see there is enough room in between, more than you would have available with a tubular runner (if it would fit in this car anyways). Again, if the single kit fits the mk3 body, it will clear up the jza80 body even more! http://www.solidus-ict-2.demon.nl/mini-DSCF2023.JPG The turbo is set about 12mm more away from the engine (the manifold is about 12mm wider). This gives all the advantages explained here previously and this space is available anyways. In my own car I don't have to adjust the downpipe, because it's flexible enough. If we are compiling a turbo kit with this setup, it's obvious the pipes need to be made to fit the whole configuration. Welding and design depends on the used turbo and used wastegate as well. On my own car I will install the HKS racing wastegate (GT spec). http://www.solidus-ict-2.demon.nl/mini-DSCF2024.JPG The next picture shows the space between the compressor housing and the manifold. As you can see, it's enough for the SP67. I do have a greddy T88 somewhere here also, but I haven't had time to make pictures with it yet. http://www.solidus-ict-2.demon.nl/mini-IMGP0810.JPG Well, that's it for now. For all the people who asked me if it's for sale. Yes obviously it is. However, this is not a commercial post, nor will I be able to sell this in the USA anyways due to the postage and handling involved. I'm discussing a distribution with one of the big names in the states and they will announce it when it comes that far. In the mean time, just enjoy the pictures and give me any feedback you might think of (positive, negative or pointers or whatever). On monday I will have new contact with the casting company to discuss what was needed to make the fit from 'good' to 'perfect' (I did some grinding), I hope they will do that for me on the commercial samples (this has all been prototypes yet).

arnout Posted November 22, 2004 Author Share Posted November 22, 2004 Today I made the threads to the holes for the turbo and the wastegate. This thread is just regular M10x1.25, the standard M10-fine thread used by Toyota. So, we can use any good Toyota stud. Here is the first picture I made today: http://www.supras.nl/iB_html/uploads/post-2-45866-mini_DSCF0002.jpg As you can see the gaskets fit the manifold without a problem. Next I tried the turbo on the manifold. To easy reach the bolts for the turbo, I've put the turbine housing on the manifold first: http://www.supras.nl/iB_html/uploads/post-2-45922-mini_DSCF0006.JPG Here you see the exhaust flange with a V-band clamp: http://www.supras.nl/iB_html/uploads/post-2-45961-mini_DSCF0007.JPG And the full assembly: http://www.supras.nl/iB_html/uploads/post-2-45989-mini_DSCF0009.JPG That's it for today and most likely even for the week. This week I have to discuss the final pricing with the mold-maker and the casting company. Also the finishing details must be discussed (resurfacing and heat coating etc). After that I have a final price on the product. I will also take the flanges to my welding guy and make up some midpipe and wastegate setup.

eyefi Posted November 22, 2004 Share Posted November 22, 2004 some good pics. it's alot larger than it looked in the first set of pics, now its on an engine. r u going to polish the inside? impressive stuff. Quote Link to comment Share on other sites More sharing options...
arnout Posted November 23, 2004 Author Share Posted November 23, 2004 Originally posted by eyefi r u going to polish the inside? No i think not. if we do the whole coating and stuff, the manifold will be good enough I think. No need to polish. Quote Link to comment Share on other sites More sharing options...

arnout Posted November 29, 2004 Author Share Posted November 29, 2004 Does anyone have experience with these wastegates? I got them today, they are made in china and SS autochrome sells them on ebay also. Wondering if it's any good for my turbo kit. http://www.supras.nl/iB_html/uploads/post-2-60840-mini_wastegate1.JPG http://www.supras.nl/iB_html/uploads/post-2-60858-mini_wastegate2.JPG Quote Link to comment Share on other sites More sharing options...
eyefi Posted November 29, 2004 Share Posted November 29, 2004 a short while ago i had a quick investigation around the supra scene and didnt turn up much info. horsepowerfreaks where using one in their kit, might b worth asking ChrisBergemann about it. i dont think the gate has been around for very long. the honda forums where the next place i was gonna look. look here Quote Link to comment Share on other sites More sharing options...

Agree, it use to be interesting to see what Arnout was working on. Perhaps we should just offer all foreign members free membership?

terawua Posted April 18, 2005 Share Posted April 18, 2005 FYI guys Vortex hold 5 of these manifolds in stock and are currently building a full kit around them. Any ideas of price yet Terry? Budget single territory, or more? Oh and does the wastegate vent to the exhaust in your kit? Quote Link to comment Share on other sites More sharing options...
