depends what do you wanna play
you want to go more on higher boost go for turbo
you want better response go for super charger
if you go for turbo you need to decide what kind of turbine do you want and single or twin turbine. They are selling the turbo kit at
www.kia-fx.com
but do remember one thing
playing with turbo & supercharger ain't cheap
why?
you need to change your camshaft, pistons, etc
why?
because it can't might not stand the boost.
As for myself I'd stick with stock.
It isnt worth unless your engine already koyak then go for a transplant with a mazda engine. It fits nicely for a B6T or B8 210
Also you need to set your priorities straight. What do you want to modify first?
Engine first? Handling? or Braking?
I myself would rather go for basic engine mods like breathig system, spark plugs and spark plug cables, voltage stabilizer and grounding, Strut Bars(Handling), add some gadgets of two but not too many as I don't really believe in those gadgets. Thats as far as I would go for the engine as I am not going to race it. I am just modding it for smoother and easier acceleration.
As for suspensions I'd change to adjustable coil over with helper springs but Titan customised sounds inviting to me.
Braking system........I am satisfied with the current one. Maybe change the fluid to a Dot-4. Why? I tested emergency braking at 145km/h and it performs very well. Everyone was like Whoaaaaaaaa. never knew a spectra could brake that way.
As for ICE, I am just a basic ICE person. Nothing serious. Maybe a sub to compliment my mids thats all. I am more to SQ.
Do remember that certain engine stuff are not permanent as when you change cars you might have to sell it off with the car where as ICE you could just remove it and place it in your new car.
Therefore I strongly believe that basic mods is sufficient unless you are a racer.
As a racer only race in tracks. Do not endanger yourself and others.
