The original manifold was a really good design for flow, the only reason you probably saw any increase was because you removed the catalytic converter which was probably the only real restriction in the exhaust system

[@TheFRiNgEguitars]

Good point! But also a factor, the longer primary tubes on the header scavenge better in the mid band, increasing torque through the power band.

[@rbm4163]

Looks like that NA had the stock iron head swapped out with the NB 01 header, which is pretty decent. I had a 00 with iron header, swapped it out with the 01 header which I had powder coated and kept the heat shield and have the RoadsterSport mid-pipe and RS4 exhaust along with a CAI and MazdaSpeed intake camshaft. The engine really pulls above 4k and has a nice low burble when cruising around. But, when you are really going in the canyons, it's sonorous and responsive. Stuck with he 01 header so I can pass emissions testing, plus it was cheap and still better than the Iron one.

I'm surprised you made as much as you did. The weather (temperature and pressure) might have accounted for the difference you saw. The stock header didn't look like a bad design (unlike a lot of the horrible cast iron headers found on many cars), plus you ditched the heat shield, which means you're losing energy from the gases which can reduce the ability to scavenge and you're increasing your air intake temperature.

[@JonarusDraconius]

Some sort of re-tune would have to be in order at some point though - All these parts, and the limited gains from the parts themselves? You could gain so much more from a re-tune that is actually mapped to take full advantage of the parts. That is why on my L36 engine build (Holden Commodore, being Aussie and all), I have every intention of replacing my stock engine management sooner or later, even though my plans don't go beyond "mild daily-driver NA spec". Bonus - A retune with better equipment should not only gain me even more power, but actually make the engine more fuel-efficient too! ~JD

[@ckbhack]

In order to pull this off you really need to go to a standalone. Miata ECUs do not lend them selves to easy tuning.

Older vid, but good info and fun. The stock Mazda part looks really great. Typical engine with log style irons can get 10% gains with long tubes. If you're looking for a few ponies, get rid of that heat soaking under hood air filter. Get your stock box back and use a KnN drop in. Sucking in hot under hood air causes your PCM to pull timing to prevent knock. Also, run a 160 thermostat if your car won't throw a CEL, otherwise a 170 will net you a few ponies as well.

Wow, this takes me back to 1968 when I bought a Datsun 2000 roadster that had 135 hp stock. I was stationed at Edwards air force base and we had unlimited space to run flat out. I was in the army and one of the civilian engineers (MIT) had a new Porsche 912 targa and we would race in the desert . I could always beat him on top speed (135 mph) but cornering I couldn't keep up. I decided to look into speed equipment and even being a So Cal boy in 1968 Datsun was like what? Luckily I went to Iskendarian looking for parts who sent be to Pete Brock who had an operation sponsored by the Datsun factory to develop racing cars and parts and to support independents like me too go fast in Datsuns ! I bought the factory racing cam, side draft webbers ,factor racing headers and to many small items to mention. I swapped out the stock 560-14" wheels and tires for Minilite magnesium wheels with Goodyear Blu-streak racing tires. The Porsche guy was in shock when we had a chance to go again as my funny little Japanese Datsun with north of 200 HP could go north of 160 mph and corner as good or better than the Porsche! I didn't find out until years later how famous Pete Brock was! I'm still remembering him and his also famous mechanic being regular super helpful guys actually turning wrenches under my hood when I was just a soldier back from Viet Nam stationed at edwards AFB....they treated me like a VIP !

Only if the flange is really thick and you don't get exhaust leaks.

[@eniklisnihm4565]

@Darth Giggity Had leaks for years on my 1967 pontiac, took it in to old timer guy, he planed the head and the header, and used no gasket, been on there for 22 years now and not leaked! So I'm going with thick flanges.

The stock header looked REALLY good. The headers also replaced the midpipe so he now is running catless. I'm not sure the headers themselves did a thing.

[@jedadiahtucker2132]

was going to say the same thing mazda forked him on that one, the stock manifold looked pretty well set up.

[@rickhayner2514]

In my opinion you could tell by the looks of the stock Mazda exhaust header that the after market header was not going to give you much more power. Replacing a stock cast iron header is one thing but the stock Mazda header was a tube header and looked pretty sweet.

as a guy who works with carbs and manual distributor timing, you do. that timing could probably be advanced and make even more hp. stock timing on most older cars is retarded waaaay back. some adjustable cam gears to advance the stock cam about 4 degrees would help too.

[@Dudeman9339]

The MOST important thing to do when you change the airflow of any vehicle is to TUNE IT. Just adding headers, exhaust, and intake arent really going to gain you anything without a tune.

[@benwilliams3539]

Yep. You may be getting more air in but not much point without telling the engine it can now also spray in more fuel aswel

[@dr.hugog.hackenbush9443]

Depends on the year and complexity of the ECU as well. Older setups can make gains without fine tuning, but youll allways make the most of what you do with a little fiddling.

[@wolfbloodchain]

Yep agreed. The Miata has a new engine map and will need to be tuned to reflect that

[@jerrodriley4290]

Nah, maf and o2 sensors will adapt. The header just straight up didnt make any power.

They did need to tune the car because the header & the intake were changed from the factory configuration. They really should have put a real CAI on. If they tuned the car with that setup, it would have probably gained 5-7 hp realistically.

Would assume they've pretty much optimized the original ones for the stock engine to begin with. But i guess this could be called a success since there was no reduction in power with the new headers. Unless low end torque suffered making it worse to drive in normal conditions. I would call this plain dumb if you have to spend $400 and a half day for basically nothing, or possibly making it worse. Denying that this wasn't worth it is just human nature to make you'r self feel a little less of a fool.

You don't have to tune it to get gains but they will be small and a tune will compound them. I would say the intake and the rest of the exhaust has already helped a bit. I would say starting stock at 100hp at the hubs and now 107hp is a good gain from better flow with no tune

When I switched to dual 2 1/2 with race mufflers you could feel a big increase, probably around 15 to 20 horse difference because the smaller tubing was restricting the engine.

My current plans are to mod the v6 a little bit for some fun but I've also tossed around the idea of just putting a v8 in it eventually.

I do however have access to an old small block 350 thats been sitting in a pickup since forever. Do any of you guys think putting an old school 350 in a modern Camaro would be in any way an upgrade from the current v6 that makes almost as much power?
