simple man.
going of my asumpting on you having a 32 rb20 gtst???
as for exhaust i also asume you have somthing as majority of 32s come over here with liek a hks or kakimoto.
1. spent 300-500 on a fmic kit, chinese / jap do the same sort of job. (ISC, Coolerpro, Basic Hybrid) if you spend money on a hybrid they come with instructions, if you pm me your email ill email them, have a read and think about doing it yourself.
2. spend 30-80 on a boost T, asuming you have a boost gauge go for a drive and bleed 10psi.
that will be safe an effective.
