Howie at HE Performance makes custom manifolds for around $600 usdBNR GTX14 1.4T Turbocharger Kit
Using a big ball bearing turbo requires hand built Turbo manifold which is not ideal, and no one is making them atm...
But keep me posted on this because if it's cheaper than 600$ I may go this route and use my srt 4 Turbo I have laying aroundI'm looking to design a manifold flange for the 1.4T, I was going to make a 3D model of it so anyone who has a machine shop nearby can get one made via CNC.
Going to order the exhaust manifold gasket and use that for dimensions, hoping I can print it out on my 3D printer and do a test fit before I send it out to be CNC'd.
Should be a pretty low cost for anyone wanting to make a manifold, From what I can see, bigger turbo setups (Such as Mark's) use a manifold design where Cyl 1 & 4 go into 90 deg elbows, and Cyl 2 & 3 go directly into the Collector/flange. A very simple design like that could probably be made with a MIG as well, As long as the welds are pretty much perfect.
I made this horrendously crude model in tinkercad to show what I mean: View attachment 233842 View attachment 233850
