I have searched the interweb and forum for some clues as to what is on my bench!
I recovered my car from a mechanic who failed me in a big way.
The original engine was not only missing but also the replacement engine I bought and I was supplied with a engine with no documents or history.
I am in the process of a full tear down and rebuild but cannot workout the EJ20 variant.
The clues are thus:
DOHC with AVCS
Cam runs on bucket that is specific to gap, no shim on or in.
open or semi open deck (pic of this)
Common coil pack that is on manifold, off center.
Inlet manifold is red but I suspect this may have been painted!
The block is stamped EJ20BUG with 270074 serial number.
Cam belt adjuster is piston type pushing wheel not integrated type.
I need to order the gaskets and seals so need the engine type.
I have a rebuild kit but half the parts are wrong including belt tensioner.
Help greatly appreciated.
