I can't wait to see some pictures. I am honestly very interested where you are fitting an EFR to still be AC/PS compatible.

I think I know of a couple ways it will fit, it'll be interesting to see what they do. Since they all have some pretty different downsides (intake or downpipe restriction, or pushing the limit of the angles the bearing will take). She's a big bitch when trying to put it into the engine bay when you think of how small of a turbo it really is.

A top or even side mount should fit the EFR and let you keep ac and ps. The harder part then is IC pipe routing, especially on NA cars that have the popups

On a more serious note, what is the advantage of machining sand versus doing a lost-plastic process with an FDM positive? Seems to me that the latter would be faster, less labor-intensive, and allow for more complex geometries.

Andrew,

Any recent updates: I thought you had a go with Foundry and we could be looking forward to track-built Miata turbo system.

FYI: today I watched Marc Hoover in T1 at Laguna, quiet an impressive performance by Turbo Miata.
It inspired me.

Lots of progress, but nothing I am interested in discussing publicly. If you are meant to know more details at this point, you already do. I will have more information for the general public when the production samples arrive in a couple of months.

Do you know how bad I wanted to edit your posts and make it say that the kit is ready for shipping?

Probably as bad as I wanted to make it say the kit was ready except he was still working on good sourcing for Inconel nuts.

This SLA has been sitting in my office for a few months now taunting me. I haven't talked about it because so much of the process has been up in the air, but the big stuff and a lot of the little stuff has been nailed down now. The foundry is chosen, meetings held, the PO is issued, and the (really scary big) check has been cut.

The only question left to ask is this: Who wants one?
  • Designed to fit the Borg Warner EFR B1-frame turbocharger family (6258, 6758, and 7163)
  • 3D modeled from bare flange locations
  • Shell mold sand cast - similar resolution to an investment casting at about 1/3 the cost
  • Cast and post-machined in the United States
  • 347 stainless steel
  • 4 into 1 tubular-style. Computer modeling during design has the "blend point" of the four runners beyond the end of the outlet flange
  • Unequal length, but small volume. The focus here is on response over ultimate power
  • T25 outlet lets us use the small-A/R EFR turbine housings and keeps cost down. With Inconel studs, flanged joints are stone reliable

This isn't a 100% final part, but it's basically there. There are some wrench relief cuts that aren't shown here, but the fundamenal shape is what you will get out of the box. I am approximately 6 months from shipping production manifolds. I should have a single working sample in about half that time. Foundries work s-l-o-w-l-y.

There will be an initial group buy for those of you who are interested in helping me capitalize the 5-figure mold and 5-figure initial purchase order in exchange for a discount on the manifold and a sizeable discount on a turbocharger to go along with it. The manifold will be sub-$500 for this group buy. I'll announce more details about that part of the process in the next week or two. We will, of course, bundle a downpipe with the manifold/turbo, but I don't have any details to share on that. Needless to say, it's getting a similar level of attention to detail as what's been put into the manifold project.

I never thought I'd see the day. Welp, I'm in for a mani/turbo/downpipe.

Wow, congrats andrew. New brakes and new manifold announced in the same week? Looks like a lot of hard work is finally coming together.

Where do I sign up for the 1.6 version.

Oh man, that is exactly what I wanted to weld up back when I first started down this rabbit hole. I'm guessing fully fabricated downpipe?

I'm local and already have an EFR, built motor, MS3 and EV14s plus you already knkw im really I'm good at breaking ****. Let me know when I can buy one. If I can't break it you know it'll be golden.

Glorious update, I can't wait to see one in person!
