Excellent - that's the answer I was after. Thankyou.

There was a diy thread few days ago that was also very good guide.

Don't forget ARTech. Abe's stuff is some of the best in the business. And IIRC, Tim (absurdflow) is not currently taking orders.

Since the day I bought my ebay manifold I've looked for a replacement that would work with my 1.6 and Mitsu-flanged 16g turbo...I have not seen one in a year and a half of looking.

Here's what I came up with option-wise:

Buy an FM/Begi manifold and use a flange adapter to convert from T2/25 to Mitsu 7cm, or cut off the flange, weld on the correct one, and hope/pray that welding to the cast mani would hold. Then I'm only left with remaking the dp to fit. I didn't like either of those options.

Pay someone (Artech for 1.6) to fab a whole new mani/dp setup, or attempt to do it myself. Don't want the downtime associated with either, the cost of a custom piece, or the fail of my own rushed attempt.

So I went the direction of buying a relatively inexpensive complete mani/turbo/dp combo that will keep my car on the road indefinitely. Then I have all the time in the world to refine my welding skills and remake my 16g mani/dp. Then resell the interim turbo setup to recoup that money.

I'm actually a bit surprised that given it seems this is not a one-off issue, none of the manufacturers/suppliers - even the ones that specifically service this community, have come up with a reasonable price replacement for what seems a popular setup - I'm facing (it seems) around $600-$800 to get a mani (or more for mani and dp) fabricated locally, because none of the off the shelf options match the current placement of mani-turbo-dp, and no-one locally has gone down the same route I have.

You guys in the US seem very lucky to have so many more miata-turbo resources - here we have very few.

Building and marketing a quality replacement manifold specifically for a market of people who were too cheap to buy a quality manifold in the first place is not a sound business decision.

Show me where I could have purchased a high quality, commercially-made manifold for my 16g two years ago and I'll go back in time and buy it. I still don't understand why there's no good manifold on the market, for either 1.6 or 1.8, that works with a Mitsu footprint. It's not for a lack of interest, evidenced by the number of shitty eBay manifolds for that application that are sold.

This should probably be posted at the top of every FI-specific Miata forum everywhere.

If you think the market is there and no one has jumped on it then this would be your chance to do just that. Even if you can't fabricate you could partner with and make some money. If you aren't willing to take that risk or put in the effort then you must not be too confident that there is money to be made.

Quality parts cost money. Why would the manufacturers/suppliers - even the ones that specifically service this community make parts for people who were being cheap in the first place?

If begi or fm or whatever dropped their prices by 100 bucks per part, people would still buy ebay and cry about it.

I made my 1st manifold myself. Spent about 300-350 in materials, but more importantly, a TON of hours working on it and making sure it fits and works and all that jazz.

Now consider someone that wants to make a profit off this: how much more would they need to charge for it to be worth it?

Suddenly, 600-700 for a mani really isn't unreasonable at all. Hell, the only reason begi and fm can sell their logs for 300-400 is because they made a metric shitton of them and are making more money off quantity all total, and not each unit specifically. I bet their profit is no more than 10-20% or something silly like that.

Quality costs money. The only way to get cheap products that are GOOD is when you find someone that doesn't value their time or makes eleventy billion of something.

ETD used to make the cheapo ebay style, but it wasnt popular and it was a bit pricey, but well made. It also wasnt advertised as a "miata" manifold, people would have a better chance searching for a BP 1.8l or ford escort GT/mazda GTX manifold.

If I had $50K to play with for R&D I'd do it in a heartbeat. I mean ****, I've been trying to buy that HKS setup for sale here for 2 months...perfect manifold to copy and adapt new flanges to. We've even got a 3D scanner at work to get the ball rolling on the CAD files.

But I still don't have startup money, so yeah, not gonna happen.

nonono, I mean ive seen their version SIMILAR to the one they sell on ebay, but thicker steel and more reliable. When you mean long tube, do you mean the singular runner type?

Eh, no worries. I know what you mean now. I was confused because the ebay long tubes are actually ripping of Corky's s4 design and are bottom mount, while the ETD is a top mount (though I see the resemblence now)
