Garret GT40 questions?
 

so i found this turbo new for 899. i have some options on it and i was looking for some input on which way to go... compressor: 82mm, 50 trim .58a/r
88mm, 54 trim .72a/r
Turbine: 73 trim .94a/r
84 trim 1.19a/r
84 trim 1.34a/r
what would be best for more road than drag but i still want fat power. spool sooner but not too much back pressure.. half bridge later hoping to make semi p-port with the half bridge/primaries/secondaries..... needs to flow big ## still

what did i say something wrong..
