How To Tell If my 1998 WRX is JDM model

[Guest]

This is the car

With this interior am I Right to think Its not a V3 , It would more likely be v4?

[ben-jamminn]

v4. but technically the 'version' moniker was only given to the STi models. WRX were just distinguished by manufacture year (MY98)

[kamineko]

hmmmmmmmm weird

love to see what ecu code it has

The weird Bit being That If its V4 it should have vf23 not vf22? Im 90% sure I read vf22 not vf23, Maybe its been replaced at some stage .

Ill confirm vf22 on wed

V3 sti def came with the the vf23, as did the 22b. Hmm theres a turbo thread somewhere in here that went into what year got what.. I was under impression the vf24 came in v4, 28 in v5 and 29 in v6

Yeah, but you are talking STi factory fitted turbos. I've only ever heard of the 22s being factory fitted to non STi WRXs.

indeed i am, and yes correct with the 22's - i was simply "eliminating" what the others came on.

i dont think we ever listed what v1-v6 WRX's came with.

97 and 98 wrx came with vf22 - late v3 and v4 only

once i had a v4 wrx 1997 and after that a v3 sti 1997 as well (no really!)

and the v3 sti had the vf23 while the vf22 was on the wrx

they were pretty much equal in performance bit the sti seemed better somehow

WRX turbos change with market, jdm manual is TD05 ver 1-2, vf22 ver 3-6, but it can vary as ive seen some with td04's, that are imports????????? confusing. all nz market ver 3-11 wrx have a td04 varient.

mines exactly the same, 98, yellow injectors, vf22 etc.

big hp boost over standard wrx's! supposed to be 280hp the same as the STI's.

[kamineko]

yeah they go well, but the tune is pretty dull compared to the STI. these cars are perfect for a sti ecu swap ;D

[SimJen]

the tune feels fine in mine.........

[gazzy2000]

do the JDM engines that get the VF22 and yellows (STI bolt on goodies) do they get STI heads too? (speaking about v3/4 here)

I was under the impression that the JDM engine gets ALL STI bolt on goodies, all bar the forged internals... so yea heads = STI??

EDIT - i have a JDM ECU and a STI ECU for my BG5 ST project, so i will be able to compare them

[Pappu1]

different cam profiles in the heads
