Not 100% certain on what models the type R and 2003 STI used. It'll start VF for sure and have a two digit number after.
I think the standard turbo on an R was a VF22 but could be wrong.
I'm sure one of the guru's will verify shortly buddy.
Classic usually have VF22,VF23,VF24 or VF28 or TD05(16G) or TD04(usually these have WRX)
And on your Type R i think standard turbo is VF24,but maybe i'm wrong
New age STi have usually VF35,VF30 or VF34(only one model this have Spec C Type RA V7 bugeye)..
You might have to look really carefully at the plate as the numbers can be quite faint sometimes, unlike on the td series of turbo's which are normally stamped in on the body.
