im gettin ready for turbo buyin parts ill need right now i got an aem fuel rail, skunk2 IM, exhaust, next im lookin at the s2 tb but cant seem to find a good size for the car because i was reading too big or too small can hinder the performance. i know the 16y8 has a 56mm tb and i was wondering if i should keep it the same or up it to a 65mm.

 

i'd leave it for now and try it with the stock one. you might not need a bigger TB depending on your power goals.

 

my idle flux up an down when in park and neutral so i wanna get a new on anyways, i looked for vacum leaks, drains fluids, changes iacv so now im ready to just replace the tb
