Are you serious?

This is opening a can of worms but why a 23? @blaze2099

If its old tech what would be the now-a-day choice for a moderately sized turbo with lower boost threshold as well as a decent amount of power through the whole powerband?

Forced Performance Turbochargers: FP 71HTA Turbocharger for Subaru WRX/STI

If you want something smaller and faster spooling than that (which already spools faster than a VF23) then just get a regular mitsu TD05 16G turbo. They come in many varieties.

Or a VF39, 43, or 48 will work for much less cost.

You don't need cams.

Okay are those easily bolted on to the 02 wrx or do they require modification? Also at what point do i need cams? because i already have some and if i dont need to put them on great, but i would like to know when they become necessary.

Yes, it's a "bolt on" turbo, as much as any non-stock turbo is.

VF39/43/48 are all similar sized and considerably smaller than a VF23. You also said <$2000 which is a very high pricerange for a smallish or medium sized turbo.

If you are considering turbos of this size, you don't need cams.

Its not that i want a small turbo, i want one with potential to reach 350 whp while still holding a decently low boost threshold. At this point i am only aiming to reach 300hp due to the fact its a dd. thats why i was thinking the vf23, it fills the criteria i want to obtain. Also thank you for lettinge know i wont need the cams. that will definatly save me some time.

VF23 is not considerably larger than the ones I mentioned. It's smaller. It has a larger exhaust housing, but smaller compressor side. The modern VFs will make more power, though the 23 will be negligibly more responsive.

Another point is that you're only talking about a +/-10 whp difference between a VF24 (smallest Impreza VF turbo) an a VF22 (the largest Impreza VF turbo).

You don't need cams until you're pushing something closer to a 30R (100 hp more than you want to make).
