People have spoke of doing cam swaps from a miata, but you will find a lot of conflicting and non useful information on it now. What you really need to do is starting pricing how much things will cost to do and weigh the benefits against each other. All of the N/A work that you might have to do to get X gain could easily cost more than what it would take to get the same gain with a low boost turbo setup.

That being said, there is a good deal of information in the FAQ's just you need to set it so it shows all the threads and not just ones of 30 days old.

This thread has some good pictres on intake installs.

Just read a lot on the forums and you will start to see what you can do to gain the power you want.

I've read allmost every thread that interest's me even the older one's but in that kind of question i have,i found no answers.for example for the bolt on kit i must pay 2000 euros here in greece,but for the regrinded cams 300 euros and for the exhaust system 350 euros(because i 've already have the half system).and also i love N/A tuned engines and i have deferent opinions for the benefits that provides the turbo.

as to the degrees of timing i have no idea.... you can just use a timing light to check it and make sure you don't advance it too far, we just adjusted it a few seperate times and drove it hard to listen for nocking and power loss. I'll see if i can get a pic... it might be easier to just have you stand at your car and look for it as i describe it cause there aren't many hoses coming out of your TB

A lot of the information you get back dependson where you dig, I have posted this link many times it would be hard to find where without knowing to look specificily for it. As much as I like to tell people to search I realize most people are not good a data mining.

This one talks a lot about hwat you are oging to want to be doing, reading the whole website could be useful even though its directed at miatas, which for a few years used a similar motor as the Mx-3.

Better yet, read the whole webstie it will help.

http://members.aol.com/solomiata/miataCSP.html

There are lots of good articles on things for hondas or other cars that can be used for other platforms.

Is good on doing a home made intake.

I would also like to point out you need to measure gains of modificaions vs doing a motor swap. If its going to cost 1500 to gain 30 horsepwer and you can do a swap that gains you 25 yourself for 1000 then your cheaitng yourself. As a general rule of thumb the higher displacment from a better swap will allow more gain per each mod you perform as well.


Also never underestimate weight reduction. Its cheap to do and makes a diffrence, also suspension is important as well.

Did you do a rear disk brake swap yet :)

Regrinds typically are not going to be popular, most people turbo because that is what the motors do best. Even when you spend a lot to make power N/A you can spend the same amount in the US on a turbo setup that will make more power and torque, pending what labor costs you anways.

You will want to look into Miata cams and how to use them on a MX-3, its might be better to grin down a set, or even oreder, a set of miata cams that meet the profiles you want. Cam profiles is way more complex than most poeple online can or are willing to help you with though. If you have someone local who is really knowledgeable I would suggest talking to them about it.
