need help
 

hello everyone,
well i own a 90 miata, and ive been working on it to make it better and so far im loving every minute of it. I just came out of honda's and toyota and now own my first na. For now im looking for more power, my recent upgrades i have slotted rotors, and tokico illuminas.

Then i came around that hks makes cams for the 1.6L and wondering is their gain out of these?
Also will the original valve and springs handle these cams?

Im hoping if possible to get 130 rwhp w/o boost, like i picked up project magazine and showed 91 na with bolt ons i/h/e went to 115 rwhp, hoping maybe with ligther pulley, hks cams, adjustable gears could get me to 130rwhp. Still thinking bout the greddy kit and call it a day, but dont know if it requires tunning, because in my town i was told they want me to pay $2000 to $3000 for installation and tunning.
thanks in advance

2000 dollars is worth the kit and installation....the kit runs from 1300 to 1600 new, ansd with the installation, do it.....i am thinking about getting the greddy kit for my 90 miata, but i have so many miles.....

my 92 has the greddy kit on it and i love it. it is my first turbo and could not have picked a greater one. I only paid 3500 for the car and like i said it already has the turbo, roll cage, pimp ass rims, great tires. It was a steal if you ask me. I would do it to mine if it didn't have it already. Don't know much about turbo cars but learning alot. the car has 147000 miles and drives perfectly. Hope this helps and here are some pics.
