.36 or .48 A/R Hot Side
Right now the turbo i have is a T04E with 50 A/R cold with a 57 Trim and . 63 A/R hot and it start's to spool about 3300 RPM's and it's ok but i want to spool about 2500 RPM's so i was thinking changing the hot side either to a .48 or .36 so what do you guys think what would be better the .36 or .48 A/R to get me to my goal of 2500 RPM's Spool.
.36A/R
.48A/R
.36A/R
.48A/R

maybe autocross, I spend alot of time in mid 2nd gear

Yes as well as some stage 1½ mercedes turbos that are also .36 a/r ! This is choking the exhaust stream big time!!
all the .36 setups i made, regardless of the engine, lacked top end. it just doesn't flow enough exhaust. I would also avoid it and stick with .48 a/r minimum.
Stage 1½ in .48 a/r is a good way to improve low end without impacting the top end as much as going .36 a/r.
