Style chooser

hi to all bro out there,

I own a proton perdana with a standard mitsubishi eclipse 4g63t a/t. yesterday i got a problem with a throttle body. I go to workshop and mechanic service that throttle body but that mechanic says this throttle body won't last long. I go to kedai potong and they says that throttle body is very hard to find.so i think maybe i can change to s90. but the problem is can standard turbo with no management using S90 because its bigger than standard throttle...
