After searching several posts I am still not sure which would be better for a N/A application. I know that 60-62mm is too big. What do you guys suggest for a 2.4 with full 2.25" exhaust system and WAI intake. I am also considering getting a HO mani but don't have the $ yet so I'm just going to go with a new TB to free up the flow. Thanks.

56mm ..theres no reason to go anyhigher on an NA engine unless its built..and even then its iffy
