How Much Power For These Mods

[paulr33]

im with craved, sounds too small

why are you dead set on this turbo?

have you seen a compressor/flow map of it ?

Its took me 6 months of research to only partially understand how turbos work when it comes to wheel sizes, housings etc.

I highly doubt a t4 will manage 500hp with those covers.

I have a Garret GT30, with a .7 Comp Cover, and it needs at least a .86 rear housing to flow enough exhaust to make over 270rwkw.

.58? Did that come off a GT Starlet or something? Thats way too small. You car will max out at about 230rwkw.
