Cool.
230whp in a Miata is a lot...equivalent to 300whp in most of today's more popular tuning platforms.
There is also a very distinct line at 250whp as far as investment, return, and reliability.
Miata rods (all motors), and the 5spd both become timebombs over 250whp. This means you'll need a 6sp and a built motor to push more than that. Also, most kits are suited to the 220-250whp range, so you'll be looking at a bigger turbo, possibly custom manifold and downpipe, and a 3" exhaust.
If you start with a '99 though, the head flows better (higher ports), and I'd consider those worth building. A few guys here are pushing a little over the 250whp mark easily, but are using some of the best engine management out there to avoid being at the ragged edge of timing and such, which could result in killing a motor.

To be honest, with the exception of boost pressure and fueling (and some other small things), the difference between 300whp and 400whp is pretty negligible when it comes to reliability. You will need a built motor, a six speed, and some sort of aftermarket LSD(or an rx7 unit) to reliably handle either if you beat on the car at all. Most people around here seem to shoot for 200-250whp as a reasonable goal for a street car. Horsepower is just a number anyway, drive a 250whp miata and see if thats enough for you ![Giggle](https://www.miataturbo.net/images/smilies/gay.gif)

I want to start off with suspension and run good wheels/tires(maybe like 255-275 not sure). I assume a lot of people that run cheap **** have traction issues with significant power gains.
