Perhaps have a three piece manifold: A top portion of the plenum (pass. fender side of the plenum), a bottom portion with runner holes (engine side), and runners. With this setup you can put the runners into the "bottom" of plenum and weld them down from the inside, weld the top and bottom together and trim the runners to suit length requirements. Not sure why FM hasn't considered something like this; NOBODY has a real option, ready to ship.

With this, you can custom fab runner lengths on the fly. Only issue is the damn cracking...

let's see how long mine will last..

above:

there's a V -shaped support plate on top of the every runner

below:

Support plates/ribs there also. (don't mind the burned spots. my desk caught fire during pre-heating)

This is the last time I’m going to repair that ****. If it broke one more time I’m going back to the OEM flat-top

What about incorporating the OEM manifold support brace?

Did you hold the tig rod in your mouth and rub your socks on carpet to weld that?

Just looks like they dipped the tip, and just kept going so now the manifold has a drippy dick.

I dont think adapting the OEM brace will be easy, I do think that making something that bolts to the same spot as the oem brace and the bolts to the plenum would work though. Then you'd have a pretty solid triangle.

that's more or less what I meant

Wouldn't making your own manifold be cheaper?

Technically that's not making your own. that's just welding it together.

Plus you don't need to pay out the *** for an aluminum pipe labeled "runner"

It just didn't make any sense to me. Aluminum can't be that expensive, right?

That guy's prices are pretty jacked up on normal stock $12 for a foot long piece of 3x1/2" Al Bar stock? Give me a break I can get 48" for 4-8 bucks.

He has "racing" in his name. Add 100% right there....

Right right! I forgot about that.
It must be racing aluminum.

Racing aluminum > regular aluminum duhhhhhh

I'm glad somebody thought that was funny... I thought I was the only one, lol.

on unrelated note
where is this cheap aluminum?

I sent an email to these guys to see if they would be willing to adapt the B18 manifold to a Miata flange. Carbon Fiber Intakes
At first glance $1,200 seems pricey but after this round of repairs I spent half that amount fixing the skunk 2. This solution seems better.

I never saw a price but I went to their " authorized dealer " and found this:

Im not sure you can get manifold from Endyn anymore. Also, he was legendary for making bullshit claims. Like his MP62 D16 Civic that was supposed to make like 500hp or some ****.

I plan to make carbon fiber intakes like those very soon!
I am almost done building my shop and should be making parts in a month or so.....
