I'm looking at squeezing a few more horses out of my newly purchased 03 SP20. I'm not really all that keen in going down the turbo path because of the insurance cost and the fact that i don't really want that much power at the front wheels for obvious reasons.

I haven't done any modifications to the engine and gearbox yet but i have a few things in mind:
Stock airbox with K&N filter and free up the intake snorkel
Headers (not sure what brand) + full exhaust (unsure what size)
Mazdaspeed LSD
Piggyback ECU for fuel management
Suspension + Sway bars ect
Short shifter

There are also a few things that I would like to do but am not sure whether they would work on my car..?

I'm just wondering if anyone has put one of these intake runners on their N/A motor?

Does this intake only work when the engine has forced induction and has anyone used it?

I'm also wondering if anyone has put the JDM camshafts in and how much they changed the performance over stock. It says on the site that they can add up to 18 hp..

I'm sure a lot of SP20 owners have done some of these mods to their own cars and i was wondering what sort of results you guys got as a guide to assist me in my build. Any sort of help with how effective these mods are would be greatly appreciated.

Cheers guys
