They were hydraulic up until the Sti 3 was launched with the phase 1.5 engine and underbucket shims. However it would seem that the Sti 2 RA had top hat underbucket shims...well Andy F's did, but lord knows if his was a 'normal' car in the first place

actually, I have been reliably informed recently that all imprezas have solid lifters, either over or underbucket shims.
Only legacys have hydraulic lifters.
Tgus the heads should be good for 7k rpm, only the pistons wouldn't be in the older engines.
This comes from someone who has taken apart more engines than anyone else I know of.

On cold mornings you can actually hear mine take time to 'pump up' .... i'd like to take a big bet mine has hydraulic adjusters
