Serious question - have you spent any time on track yet?

A stock power miata with a decent suspension and sticky tires, in the hands of a good driver, is enough of a track weapon to absolutely frighten inexperienced passengers. It is an excellent, quite possibly the best, platform to learn to track with.

Add power and that miata becomes a beast.

Power magnifies mistakes. Learn to track properly in a lower power car. Build the safety equipment and suspension into it first, and use street rubber. Add stickier tires. Do the brakes. Then add the power last, to a car you already know how to drive hard at the limit safely.

 

This is the right way to do it, and it's also another reason why IMO turbos are better than LS power for track cars. Take your naturally aspirated track car, add the ECU and injectors, and dial it in. Then add the uprated clutch and get that broken in. Then add the turbo parts, but keep the boost low while you're shaking everything down and working out the kinks. Then add boost slowly, stopping to sort out things like cooling, oil coolers, etc. With our setup, you can do that very progressively without any real power ceiling. The 6258 will be smooth, linear power delivery at 7psi on a stock engine, but it has enough headroom to make 325whp, and if you want more than that down the road, the 6758 drops into place with zero modifications and gives another 125whp of headroom.

With an LS, it's like trying to learn the car all over again, and at the same time you're shaking out the kinks. Too much going on.

 

I have 225whp in my MSM with the FM Big Enchilada. It's no joke fast. In the corners you are absolutely bumping. I'm going FMII in a couple of months to get to 260whp. Beyond that I imagine would be terrifying to take on a racetrack.

 

Nah, it's not really scary. 250rwhp is enough that all of the fast corners on the tracks I've been to are "real" corners (as in, can't take them flat), more than that just means a higher top speed on the straight and more braking.

You do need more cooling and go through brake pads and gas faster, though.

I would add that if in the corners you are "absolutely bumping," you need to look at upgrading your suspension.
