Default Turbo Upgrade on slightly built motor.

OK so i have decided to keep the wrx so yeah. I am looking to see what the best turbo would be for the car as an upgrade based on bolt on supporting mods i have on the car now.. im not looking for a certain WHP number so please dont think this.. right now im making 309whp/350wtq. just wanting to keep the same spool rate but increase the hp to a reliable point without having to worry about damaging the motor or trans. Just looking for input. Please dont slam my thread with BS..

Mods

CP Forged (Stock Compression) 99.75 Pistons
Perrin turbo inlet
Invidia Q300 cat back
Grimmspeed 3" catless DP
Perrin UP
Cobb Light Weight Crank Pulley
Fast MotorSports FMIC
Walbro 255 FP

Current Turbo is Stock VF52 Running a Cobb Stage 2 Tune @ 19.5 PSI making 309whp/350wtq.

Im thinking about running ID1000's and going for a FP Green. I know I will have to do a TGV Delete if I run the 3" outlet. So im thinking of running the 2.6" Stock appearance housing.. with an E85 tune..

What do y'all think about the idea. and what kinda numbers and reliability do u think i will have with this set up.

Tgvs are for any bigger than stock turbo generally.

You want a faster spool time? When are you hitting boost now? Does that vf52 hold until redline?

I run a greddy 18g. 3400 on a fmic running 16psi on 90oct. Just about 300whp.
Built stroker. Etc etc

Also 1k cc is prolly overkill on a fp green.

Considering he's trying to go e85 I believe those injectors are not overkill. Could use a FP green or Blouch Dom 2.5
