Acually, the number on the IHI turbos has to due with the order in which they were designed, nothing more. Case in point: A VF22 puts out less than a VF24, which puts out the same as a VF29, both of which put out less than a VF30, which puts out the same as a VF34 although the 34 spools faster, both of which put out more top end than a VF35 which spools faster than either the 30 or 34.

IOW, the number only designates the order in which they came out, nothing else about the turbo or its power/spool abilities. Therefore the only thing that can be said about the IHI's judging from the number alone is that the VF22 is an older (though not neccessarily less powerful) turbo than say the VF30, which is older than the current newbie the VF35. Hope that helps a little.
The VF-22 is the bigest of the VF's, and bigger than a VF-24. VF-24 was stock on some of the Limited STi's.

what about 300 awhp, would you need for that?

which turbo would get you aroun that power level with the lease lag? and would a STi TMIC be enough to hold up to that power?

Stiles check your facts man

The vf 22 is HUGE compared to the 24 and 29. I know what a 24 is. I have one on my car.
The VF 22 puts out more than a VF30!The 24 and 29 spool VERY quickly, the 22 spools in the mid 4000's but MAN O MAN when it spool you know it


300WHP?

here is how

Good engine management
vf30-or better yet vf22
FUll catless exh and up pipe
sti or larger injectors
Fuel pump
Bigger intercooler (sti isnt going to cut it here)
GOOD dyno tune


You are also going to need
Better clutch
Good driving skills to not waste your tranny.

Well, I have a 24, which is basically identical to the 29, and I barely notice a difference. It spools PLENTY fast for autocross.(which I do)
