Buy mine! Ship to Gotpsi?.... ~300 bucks gets you SWEET manifold

I'm new to this site and new to miatas but I was a hardcore die hard Honda head.. I can tell you that in allmotor setups the edelbrock victor x manifold is best for b series as far as cast manifolds go, custom sheet metal are best in my eyes and from experience but to each his own... Iv left my Honda dreams behind because I'm tired of all my work being for nothing when it gets.... stolen I had my 92 all motor civic hatch stolen on 8/16/10... (sleeved 84.5mm X 89mm 12-2-1 compresion b20vtec 236whp 189wtq on 93 octane and I used a victor x manifold)
I'm realy liking miatas just trying to learn and be as successful with my miata as I was with my civic..
So my question is what's a max whp on a allmotor miata?

180whp give or take 5% in either direction. Be prepared to spend ~10-12k to get there.
We have factory oil squirters, 9:1 compression, iron blocks, and a damn oil feed port pre-tapped on the side of the block. There's a good reason why a lot of people turbo these cars.

Cheap turbos like a recycled "greedy" from CL can make a 1.6 run about like a 1.8. Locally a guy added one and in 70F weather can run 0.3s quicker in a 1/4 mile than my NA car did in 100F / Humid. Which is to say about a draw. With his lag from a traffic light he is doomed in street fun. I'm hoping he'll come out to the next autocross, but have warned him that the mod bumps him way up to a mod class where cars can be considerably wilder.

If you guys are looking for a low cost manifold, there was a guy one of the the turbo dodge forums making sheetmetal intakes for cheap (like 300 dollars).
I'd bet if you found him flanges, did some research to give him dimensions for runner length plenum volume and the rest of the dimensions he'd probably build one for you. I klnow there are alof of guys on here that are proficient with CAD.
I havent done anything with turbo dodges but Ill do some looking around and see if I cant come up with some contact info.

Thought you guys should know, it didn't work out so bad. I'm going to weld those bungs shut later and smooth it out in there. A very small bit of work with the grinder and the OE fuel rail works. Also, fuel lines re-routing in the future, and the vapor canister needs to go.
Just seein if it fits with everything. Which it does.

So the long and short of this thread is:
Skunk2 with 1.8L flange welded on (CNC flange or hacked off OEM) and some port clean up from the welding should give good gains on NA and FI engine. The cost of this is the manifold (whatever you can get them for on ebay, or used) + $100 to get somebody to weld it up?
Anybody care to estimate what gains this intake would give to the following configurations (assume I/H/E mods and programmable EFI):
- 94-97 1.8L head with intake/exhaust cam
- 99 head with intake/exhaust cam mod
Why aren't more people doing this?

-Blox skunk2 copy saw nearly identical peak power and lost lots of midrange(10hp/12ftlb) on my built 9:1 NA engine with 99 head+bolt ons/AEM EMS. There is a dyno plot in this thread
-Alumnium welding is expensive. $75-100 per hr. The shop that did my motor build and modded my mani put nearly 6 hours into it they said.
-Cam mods and/or high compression may be the kicker to take advantage of the flow
-More people arent doing it, i think, because its all theory. Only a few examples on pretty highly modded cars. Not towards the cheap end of the $/hp scale untill the stocker becomes a signifigant bottleneck to flow.

Piece by piece...
What length runners did you use?
GotPSI? Will hybrid the two for 150$.
Cams/headwork is only needed above 7000ish RPM, all the intake builds are showing that.
Even on a 2560, an intake has been shown to be worth 40whp. NA, Emillio has shown it to be worth 10-15whp.
It's well past just a theory.
I don't mean to be spammin my **** all over this forum, but..

What length runners did you use?
-filled and redrilled blox manifold, ported to match miataroadster plastic gasket on the outsides of 1&4 runner
GotPSI? Will hybrid the two for 150$.
-sounds like a great deal i missed out on :(
NA, Emillio has shown it to be worth 10-15whp.
-My build showed it to be worth -10 in the midrange and +0 anywhere :(
i linked to my dyno but here it is, dotted line is blox mani and coldside intake, solid is 99 miata mani and monsterflow intake. 94 block built 9:1 CP/eagle/arp/cometic with stock 99 head in preperations for boost
I suppose "your experience may vary" this is just mine. I did it for future boost, but never expected to lose power while n/a

And you didn't hybrid it, you used the blox flange?

And really, you used a honda flange on a mazda head? Is that really true?
