  1. That would be great for N/A applications but having to adapt back to use the GTR plenum would be a pain with DCOE style throttles. Luckily many people discard this over complicated setup so parts can be had fairly cheap. If anyone wants a set of flanges I'd be open to making them. It would just be up to the buyer to fit them properly. The distance between the runners and throttle openings do not line up well so there is a considerable amount of welding to fill and porting. But I have heard of welding on the flanges and forgetting about it. I just dont want to catfish people into thinking this is an easy solution, bolt-on or otherwise. 🤣
  2. Thanks for the kind words. The flanges are really simple to make / have made. the hard part is the fabrication of the welding and porting the openings to match which is why I would be hesitant to sell them as a kit. Plus I bet very few are as stubborn as me haha -Jordie
  3. I 100% agree that another intake setup would be better performing but I like the uniqueness it brings to the build. I am not paying someone to do the fabrication and this has become something I want to figure out. Call me stubborn for being sold a "bolt-on" adapter plate. The waterjet has been down so it was quicker to machine them. I had one of my machinists at work (who is enthusiastic about making car parts) to give me a hand over the weekend. We started with .75" scrap we had kicking around and profiled out the shape. I transferred over the studs from the balance tube for a test fit. There is a slight interference caused by the distance between the top and bottom studs being off by .75mm. Not a huge deal as the split pins which locate the throttle bodies are on the bottom holes and they fit perfect. I just oversized the top holes on the ITBs to accommodate my stupid error in measurement You can see the difference in the ITB spacing vs the OEM RB20DET runner spacing here. The plan is to fill it with weld on the inside and weld on the outside as well. I can then smooth out the transition. -Jordie
  4. Bumping this thread to keep the dream alive. Finally got cracking on this yesterday. Cut the runners off with a bandsaw and machined the runners flat. The plan is to retain these two sensor locations. But remove the steel insert, cap the end and thread a nipple in which will go to an aftermarket swirlpot. The lower coolant runners will have to be cut and modified after seeing where everything mounts up. Hopped on the computer and measured up the flanges. They have been sent to the waterjet and should be back in a couple days. Ill update when the parts get here. -Jordie
  5. For the record I am Canadian 😆. I am still waiting on my spare lower manifold to show up then will be cutting and welding adapters on. Do you have any pictures of your friends adapter? Maybe there is an easier way. Like I said before, I'm a mechanical designer by trade and play around with 3D CAD for 8hrs a day. My current company has full machining capabilities as well so we might be able to get something done!
  6. That's the thing. I don't want to give up on this. I think just need to take a different approach. Adam, I wish it were that easy
  7. It was leaking from where the forward most coolant passage met the block. On the small ear. (shown in the screen cap from your video)
  8. Not the update I wanted to make but I feel its important to keep people updated. As everyone else echoed the Otaku adapter kit is TRASH and will leak no matter what. I've taken every precaution with getting this to work and it leaks no matter what I did. It Achilles heal of this kit is the added points of failure. Stock you have a single leak point where there manifold meets the head. With this kit, you create 3 potential leak points. I've gone back to my single throttle setup for the time so I can enjoy the car. Not to give up on having ITBs, I have also ordered a stock lower plenum to cut and weld on adapters I have designed and had machined at work. Ill keep everyone updated as we move forward. -Jordie
  9. Yea thats the thing that gets me. I design stuff for production at my day job. There would be no way I would release a part or product that would require that much dicking about to get to work properly. AND sell it as a bolt on solution.
  10. Here you go. Not on SAU but its pretty detailed. You might need the photobucket fix extension for chrome to see the first post but other than that its all though flickr so it mostly works. https://zilvia.net/f/showthread.php?t=579803 Enjoy -Jordie
  11. Just to update everyone. Got the car together and running. No leaks or big dramas. Ive adjusted the ITBs and managed to get everything to idle at around 1050-1100 RPM. Which seems decent by old ITB standards. Since im an expert at removing it all, I might try from throttle coat over the winter. Drove it to work today and it ran super well (surprisingly) with my tuned ecu. Once I figure out a turbo and manifold I will properly get it mapped. If anyone has any questions about this conversion, feel free to inbox me.
  12. I drilled them all out to 9.5mm and everything mounted up just fine. I used a little bit of RTV sealer to make sure it seals well. I filled the coolant with water to check for leaks and we are all good (yes I have added rad hose clamps ) Just need to get some cold side piping fitted and I should be able to start it all tonight. Fingers crossed.
  13. Got everything all apart again last night. You're right, 10 holes line up with those in the block. I am going to drill out the threads and get fasteners to go right through the plates into the block. There seems to be enough tolerance in the holes that if they are not 100% bang one (less than 1-2mm either way) it should still all bolt up. I believe that I have the right fasteners for the job but Ill assemble tonight without gaskets and double check. -Jordie
  14. no no I mean the cast portion of the intake manifold assembly. that goes between the throttle body and the adapter plate. I have it all apart again now. going to take another crack at it.
  15. it started leaking at the back. it looks like when I bolted the RB26 balance tube piece on, one of the bolts was a little proud and caused the plates to separate. New gaskets should be here today so Ill try again
