just get a vf53 or whatever the new sti turbo is, it's good for 350 i think, get tuned for e85 and call it a day.

OP, have you ever driven a car that has a larger turbo? do you think you'll like the way it'll feel (i.e. lag, power, overall reliability?)

the common consensus, which is usually reasonable, usually prevails. and that's: get the smallest turbo that will help you achieve your [fictitious and likely arbitrary] goals.

the vf52 is on the wrx, not the STI. Why intentionally buy another IHI turbo when you dont have too? The reliability of the CHRA's is proven as less than stellar....esp when having a turbo with the GOOD IHI housings and a mitsu CHRA is available.

The vf turbos just run out of steam at the top end on a 2.5. I agree with you unless he only has a few hundred dollars to spend.

18g and 20g arent even needed. just go vf52 (stock 09 wrx), externally gated with supporting mods. youll be fine.

Vf52 is a 35lb/min turbo

You can figure about 10hp/lb. I have 38lb/min turbo on my 08 wrx. I had 30hp more than a vf52'd wrx, with the exact same mods I had, that ran right before I did on the same dyno.
