Default JDM wrx ver 3 or 4?

I am looking at possibly buying this 01 rs which has a wrx swap. Thing is, the present owner (second overall) really doesn't know a whole lot about cars and is unable to tell me a lot of the specifics about the car. He gave me a list from the previous owner which mentions all of the mods done to the car. The engine is listed as a jdm wrx ver 3 or 4. How can I tell exactly what engine it is? Are there codes listed anywhere on it? Also how can I tell which turbo the car has? And if it happens to be one of these engines, is this a good thing? The guy selling the car is straightforward and appears to be very honest about the car. I just want to make sure of what is inside this thing before I make the plunge. Car also has an avo fmic, link em, rps clutch and various susp bits. Thanks for the help.

That's for the STi's--the WRX's had a vf22--at least the v3 did. version 3 and 4 blocks are both EJ20K, so there's not a lot of difference, if any.

What he said. You really will be getting the same quality and construction with a '97 or '98 engine. The catch is really gonna be the EM and ECU. Depending on how emissions goes in your neck of the woods, unless he's using a USDM WRX ECU, you may not be able to smog it. And that may be why he's selling it. I have seen many a swap get sold after a year or two because it became time for emissions and the owner just figured make it someone else's problem...

My friend has an L with a version 3 swap and it is very fast so if it is that engine it is a good thing. However his L is a 1993 therefore he doesnt have to pass the OBD2 test, in an 01 RS this might be a problem as far as passing the test, unless you know someone...

Do some research, there might be counties near you that don't require emissions--register in them.

I have a very hard time believing this, considering the VF22 is larger then either the VF23 or VF24. Plus, the VF22 is a super laggy turbo and I don't think they'd put it on a WRX. I also thought the v3 wrx is when they went to the TD04 instead of the TD05H-16G that were on v1/v2.

td04's wernt used in sedans until v5 years, not in the v5 itself but in the base wrx's. before that it was used in the wagons. the reason why the ej20k was so legandary is because of its having the vf22 in it. with a small tune it could beat any sti.

Damn, I didn't know that. So they put the VF22 on the wrx and the VF23 on the STI in v3 form? That's nuts!

my STi V4 Type R has a VF23. I am not sure there is a reliable way to tell a V4 from a V3

Well there is if the applied engine code sticker on the timing belt cover or the back corner of the block is still intact. But beyond that, it is tough to tell.

And one other thing to add. People don't generally realize that most everywhere else but here, WRX's are referred to by their version number quite often. Here, people always assume that you are talking about an STi if you say "version", but '93-95 WRX's were V1, '96 was v2, '97 was v3 and so forth. Then in '01 it gets a little sticky because in ROW it was v7, but we didn't get the v7 until '02...

Version 2 wrx had a tdo4h instead of the td-05h found on the sti of the same year.

The v1-v2 WRX wagons came with the td04 and the sedans came with the td05 IIRC.
Thanks

Are you sure it wasnt? It was based off the EJ20K which is open.

No it wasn't X 2! That is a totally false internet rumour. The Ej22G block has no relation to the Ej20k. In fact it was the first phase II engine that Subaru ever built. Ej20K's are center thrust engines...

As far as I know, VF22's never came on any Sti versions from 2-5 . When you look at the parts book, the VF22 part# isn't even listed on any model.

I'm 100% sure the EJ22G (22b) is closed deck.
