EJ20 variants

[Roo]

Have found some info but struggling to relate it to my own car.

When I bought the vehicle I was told it was "rebuilt 35,000km ago" which I call bullshit on due to visible block surfaces showing they haven\'t been machined since new

As far as I have gathered the ej20k has smooth rocker covers, and an ej20g has \'FOUR CAM 16 VALVE\' on the rocker covers.

My dilemma is that my rocker covers have the writing/lines on them, I stopped a local guy the other day with a stock v3 sti sedan and his rocker covers are smooth

I had a cdb ej20g (recently took a trip to scrapyard) in bits and the rocker covers like mine shared the writing. But the actual shape of the rocker covers was different between it and mine.

So my question is

How many variants were available in the pre 98 ej20\'s, is it unusual for mine to differ from another sti of the same version?

heaps bro : My gtb now has a CD EJ20g block running TT heads so no rocker cover identification will help you if you come across my wagon in 20 years time trying to decipher that

For a V3 STi, I would personally think it would be a 20K with the \'smooth\' rocker covers.

Oh and my wagon is a 20g with smooth rocker covers.

Yeah I reckon too that it should be an ej20k with smooth covers like this other v3 I know is original

Sounds like I should just not worry about it and if I build a motor for it at least then i\'ll know what\'s in it

Legacy experience. Bc/bf with hydrolic rocker arms had ribs above and below as well as 16valve etc.

Early bg with hydrolic buckets had ribs above spark plugs. 96 onward with solid shims had flat rocker covers. same with a 97 wrx
