This...it's about 3" back to include both the bosses and the fuel rail mounting points. Luckily the runners don't start bending down until right after that, and you can still reach that point with a dremel to clean up the weld.

1.6L intake manis are probably cheaper than flanges anyway lol*

...so 1.8 has injectors and mounting on head,- that explains why the Victor X on previous page has no provisions for fuel...sorry Im 1.6L
I got a price for the intake flanges,after setup fees & hourly,works out to $75 each,there would be a minumum of 5 to begin.They would be out of 3/8" AL.

I could also get flanges cut on a cnc mill out of 1/2" 6061 for $65-75 depending on the number of pieces, no minimum (plus shipping to you). I have gasket-matched patterns for the 1.8 BP05 and BP4W heads.

I'm not sure 3/8" is enough. You may want to price 1/2". For our 1.6s, I'd want a CNC'd flange with the injector bosses machined, but what you suggest works for the 1.8 guys.

There's nothing wrong using the flange off the stock manifold. Many fabricators do it.

That's a great price for CNC'd flanges. How about 1.6 ones with injector provisions? Any idea what they would cost?

I have never held a 1.6 manifold in my hands so I can't say. Would 1/2" material even be thick enough for the injector bosses? I'll go look at some 1.6 pics now to see what all would be involved.

Just looked at Braineack's pics and I'd estimate you would need to start out with 1" thick material to be able to have enough meat for machining the injector bosses. You would still need to weld on the fuel rail attachment 'towers'. Rough price estimate is that 1.6 flanges would cost about twice as much, so ~$150. In this case, I'd just use a cut-off stock flange...

You're probably right. Here's how SLS does it for Honda flanges:



Maybe 3/4"?

Has anyone seen this one?

Mazda MX-5 Miata 1.6l intake manifold B6 MX5 : eBay Motors (item 350303846766 end time Feb-10-10 05:02:32 PST)

Sure doesn't look like cast to me but wha-eva. Plenum too large, runners too short?

Use 4 silicon hose couplers & 8 SS T-bolt clamps to physically join the Miata flange to the Honda manifold along with modifying/adapting the stock Miata intake manifold support to the Honda manifold so that the silicon hose connector tubes aren't holding any weight. Ghetto, but very functional. FWIW, Lycoming aircraft engines have logged millions of hours with these funking rubber/silicon connector hose intakes.

YMMV
Adjustable runner length too. Seriously.

Too much for a chinese product maybe, but as far as custom IMs go, $500 is not expensive. Begi's sells for more and there's a lot less work involved in making it vs the one in the link. CNC'd flange, formed plenum/runners, velocity stacks, all that costs money.

The cut&paste method will cost about that once its all said and done (including price of new manifold) assuming you don't own a machine shop.

I've been working on pricing out Intake Manifolds, Flanges and all Welding/Labor and I might be able to bring the product to market.

BRAND NEW Intake Manifold welded to Billet Flange and Port Matched to flange.

Pricing would be based on minimum group buy of 10 Intake Manifolds. Keep in mind the 97-97 and 99-05 flanges are different.

Who would be interested at the price of $450-500 based on a minimum Group Buy of 10.

I would be interested (99-05 engine) but would like to see dyno evidence that it works well before committing.

Honestly, I don't think you well sell many if any at that price. Especially if this Honda mani works good enough. I'll have this mani on my car for under $300. I think if you or anyone can bring a decent manifold to the market in the $300-350 area you would sell a bunch.

+1 to that, 500-600$ for an intake manifold is pretty hefty when other cars manifolds are going for alot cheaper.

You got the manifold used and for cheap. New versions are $180-280ish, plus a billet flange and welding. The Aluminum Welding is not cheap. Aluminum Welders get paid very good money in my area.

Most of the money in our estimate is welding and fabrication costs.

The issue is the tooling and setup. I have contacts to make a cast manifold just like the Skunk2 or Blox but the $10,000-15,000 in tooling/setup costs at the foundry is too much unless you are amortizing it over 1000s of parts in the first 12 months... (which I don't think we have a market for with the various years of Miata)

Otherwise your price is just too high...

This is making me feel old, but I remember when a custom intake manifold would go for a grand or more. No one balked over a custom turbo kit costing 3 to 4 thousand because they knew it was a good deal (And this was in 1990's dollars). I don't know if the cheap cost of Honda stuff is the cause, but 500 is cheap for just about anything custom under the hood of a car that actually make power. That doesn't mean everyone can afford it, but its custom work, not something mass produced. Consider water reroutes are going for 300.00. COPS kits for 300 plus.
