Unless you like to upgrade for sound, those wont help you performance wise.. Just save your effort and money and just leave it stock until you get some forced induction.. And since you are planning to turbo, i suggest tons of research and reading about forced induction.. turbo upgrade without knowledge will just end up in frustrations and waste of time and money

 

DO NOT WASTE YOUR MONEY ON BOLT ONS IF YOU EVER PLAN TO GO TURBO. that should be stickied.

but really, i wasted soooo much money on bolt ons that do next to nothing except make some nice sounds (or not so nice sounds). If you want an exhaust right now get the dezod turbo exhaust that also sounds nice NA. Also do tons of turbo research. i have been doing that for 2 years and have barely scratched the surface of turboing an NA car.

GL with your tc

 

Consider this your warning page for when you go boost lol

^ That right there is why treadstone sucks. They tell you, you dont need Engine Management. There kit is alright except for what i just said and needing to cut the bumper for the intercooler pipes and removing the crash bar. That size intercooler is not needed. No other kit makes you do that.

 

ha ya i have messed with F/I before and you have to be retarded to think you can slap a turbo on and not have to mess with a tune. o well though. Some people are retarded. Donno i am starting to kinda lose intrest as far as trying to get this to get going performance wise..Kinda seems like a lost cause. Maybe its cause i am getting older now or donno.

 

The turbokits.com "custom" kit makes you do that for a completely oversized intercooler and has the BOV mounted to the core...
