thats not a EJ20k its an EJ207 sti. and yeah that has a different style timing cover than what comes stock on an EJ20k (at least different than what comes with mine)

That one in the Ebay link isn't even an STI it's probably a normal EJ205 out of a JDM WRX.

Ok, so one more question. Are the V5 and V6 cam gears and intake manifolds the same as the older engines or the newer ej205 usdm wrx? Thanks for clearing this up. I am going to be working on these engines more in the future as they get cheaper and easier to come by and want to know what fits what.

The version 5 and most of the version 6 engines have the same cam gears (and camshaft diameter) as the v1-4 engines. Partway through v6 production was when the made the change and I've seen very little firm evidence on exactly how to tell the change without actually removing the covers and gears and looking. Maybe Marnix can shed some light on this.

However, they both use the later style offset bolt pattern on their intake manifolds. You can bolt a v5 or v6 manifold up to a USDM Ej205 engine as an alternative approach to the TGV delete mod so many people do.

Matt, Version 5 is already Phase II (EJ205 and EJ207) and therefore have the same cam gear as USDM WRX.

Sorry, upon re-reading I realized I wasn't very clear about what I was trying to say.

It is my understanding that v5 and early v6 continued to use the earlier camshaft diameter but went to the phase II gear designe and triggers on the gears. Isn't that correct? Aren't there two different camshaft diameters that have been used?

Version 5 and 6 (MY99 and 00) already used full Phase II heads and cam gear, there is no transition period.
