A couple of projects I have coming up:

PFC brake pads, compound "11", fresh rotors and fluid. Ill be doing my first track day in this car on March 10 at Thunderhill (east). I picked the pads based on rave reviews on this site, this will be my first time tracking a car on anything but stock pads (previously tracked cars include Golf R and C7 Corvette, both of which seemed to work okay on stock pads, admittedly I wasn't pushing them as hard as I could). Grabbed some fresh centric rotors and RBF600 fluid.

Fresh Mazda-speed Engine Mounts. I am throwing in some new mounts in the hopes that it cures my mis-shifting into 3rd under power situation, it's super frustrating, also my friend did a minor money shift because of it...

Megasquirt! I bought a megasquirt like 2 months ago and haven't opened the box, bad miata owner, bad.

BP4W + Supercharger swap. I got a great deal on a low mileage BP4w motor with a Jackson Racing Supercharger. Not sure on my timeline on this, but my car already has a CARB sticker for a Jackson racing supercharger so I figure ill give it a go and see how she does. I have a turbo car in my life, but ive never had a supercharger, so I wanna check that whine out.

You won't be disappointed in the pads. I suck at...errr need to work on my braking and the PFCs are the most forgiving I've tried.

The car I bought had one of those. I dyno'd it before and after and it made a whopping 35 whp.
But if you live in CA and legitimately want to be carb legal its the best bang for the buck solution.

Well, I am not suffering from any grand illusions haha. My golf has like 10lb:1hp, my Corvette had like 7:1, so I don't expect to be outpacing either of them with 13-14:1

I am encouraged by TDR making almost 200 whp with basically the setup I have now + their intercooler/crank pulley... But mostly I got it for basically less than $500 bucks (with the an upgraded pulley and the TDR tensioner) , so I figure lets give it a go!

Spent the afternoon hopefully solving my lack of bump travel issues. I installed a set of custom top hats made by a local Miata enthusiast who was not happy with the quality of the isc top hats. Paid $225 for a set of four beautiful aluminum extended top hats.

Haven't been able to road test them, it was my plan to swap brakes today and my top hats were scheduled to arrive tomorrow, i figured because of President's day, but I guest the post office doesn't get many days off anymore.

Well, at least it isn't a 1.6 with an M45 like I have... I am making a whopping 145hp according to VD... I still have a stock cat and a very not good tune though. The instant boost in first and second is nice though?

Thanks! Sadly, I mostly just work on my car and rarely drive it since I've got a 1 year old son who can't really ride in it. I will be at thunderhill on March 10th though!

Haha, how much did you end up making with it? Just curious...

Haha, I hear the M45 is actually more appropriately sized for the 1.6! 145 hp isn't too bad... that;'s like 50% more than stock right?

Yeah, but 5-8psi gets old :P

And yep. About 50% more. Made 100hp on a dynojet NA with a crappy tune by me on 87 though!

I too think you'll end up with a bigger SC, or more likely a turbo.

Source- been there, done that.
