Everyone knows i have done nothing but crazy builds in the past but now im selling my car. Im going to be getting a nice 92NA 1.6l with standalone in it. I love FI but i dont know if i really need it for what i want out of the car. I have found the love of corners with my miata i have now seeing as it has full suspension.

So what could i get out of my miata NA if i did high compression, head work, and some ITB setup.

Or

Should i do a EVO3 16G setup like i had back in my NB.

I would like a 200-250whp.

200-250whp isn't gonna happen unless you have loads of cash N\A wise.

Can happen way more easily with F\I

^^Agreed. I've heard of/seen several people try to accomplish a lot of power N/A and it's not nearly as "practical" or cheap, as going FI. POPSTOY on m.net is a classic example of this. He wanted to make lots of N/A hp, but after $10k+ with all the bells and whistles, I think he's only making around 160whp... He didn't do ITB's though, so maybe you could squeeze out 180whp or so? Idk though. It's next to impossible to get to and break past the 200+ range with FI, short of swapping a different N/A engine in IMO...

I had a lot more money when I built my car years ago, I can safely say I'd still be happy with only 150whp on an NA build, but only if I went W2W racing in it in something other than SM.

Well all of that was not very promising. Looks like im going to have to go FI again.

if you want more than 200HP N/A you need to pick a better motor. Like a v8, or a wankel, or something. (200hp n/a won't happen on a stock wankel but is easy to do). and 200HP n/a is less than stock, I think even the cheap $500 5.3 LS motors make nearly 300.

I have thought out a potentially fun/cheap na motor. Grab a 99 block, some of those 10.5:1 pistons on ebay, cheap rods, BE gear, some head work (diy of course). Some cheap headers and stockish exhaust. You could get 140-150 wheel for fairly cheap.

Bend over and I'll show you my wankel.

i thought about v8 and i have done the 13b. I have an SR20DET now but i need something i can get in and drive beat the **** out of and know its not going to pop. I always seam to have bad luck so that why i was looking into the NA build.

If you want to build a miata sourced motor try an 01+, I remember reading someone got one to around 150-160whp NA. They are ~155hp (132whp?) stock in Japan IIRC with software and a bit better IM.

FWIW I have no concerns about reliability with my car, it's been mostly problem free for 25k now and returns 28mpg being thrashed daily.

Ocean's VVT high comp N/A builds are hovering around +-200whp. And that's on his personal car with all the extra stuff. If you wanted anything around there you would be paying out of your ***.

Im going to end up going turbo, im going to buy an ebay 16g manifold and downpipe. Im going to make a jig and rebuild the manifold with sch10 pipe. Then going to run a EVOIII 16G. with some 550cc injectors and shoot for 250whp.

I don't understand why you wouldn't just build your own manifold, instead of wasting time with a jig. It's going to be much more difficult (and more expensive) to get a manifold to meet the jig than it would be to just do it yourself from the start.

Seems like the obvious choice is an F20C, leave it almost stock, keep the car light.

IF you wanted to put a chunk of $$ into an N/A motor for a miata, the honest truth is: don't stick with the miata motor. An S2000 motor in a miata, which has been done, would be one heck of a fun machine, and very track worthy as well as reliable.

That said, if you want to actually get up to the 250whp mark, you just have no choice but to go turbo.

Most people commenting has never driven a well built N/A.

Do not get hung up on the whp numbers. If you are doing track duty, you will have lots of fun with a well built N/A. You will not need 200whp with a N/A car, but you will easily out run many turbo cars with 200whp.

Take that from someone who has built and loves his N/A car.
