hmm lots of options from stock depends if your wanting to keep the tmic or go down fmic. u could bang on a air filter get a plug and play ecu and it would make nice little change. personaly before u get a adjustable actuator ull want to get rid of the stock manifold before the restrictions in it are pretty mental ( jam do a manifold that looks just like the stock manifold but with no restrictions but its pretty rare to find) everyone has there own option on what the best way is but for me i would get plug and play ecu aftermarket manifold and decat and route the air filter to the front bumper ( re-locating the filter u would need to get rid of a/c so depends if u want to keep that or not.) after all this ull probaly suffer some boost spike so would most likely have to port the wastegate then its just a case of deciding if u want to run a fmic or stay with the tmic u can always upgrade to an rx7 or arc top mount which are ment to be fairly effective. once the stock manifolds out the way and u have some form of management ( plug and play ecu or fcd) u can get an adjustable actuator and wide the boost up and it should be pretty safe and make one hell of a difference. its a slippy slope tho lol my original goal was 200ish bhp now am aiming more down the 300-350 mark lol
