hello all.....My name is Marc.....and I'm a newbie... I drive(figuratively cuz it's been in storage for 4 years) a 1999 Isuzu Rodeo...or Vauxhall Frontera to you folks. its got an X22SE w/5spd. the clutch broke so I took it off the road..since then I've changed: clutch-plate, replaced OEM clutch with Exedy H.D. and Kevlar Clutchmasters disc., slave cylinder, starter, coils, rear main oil-seal, lightened flywheel, posi-rear Loc-Right diff kit, plugs, air-filter, fuel-sending unit. i'm thinking of making more power w/turbocharging. anyone have any experience with this. i'm also trying to find out which of these engines came with the variable valve timing....can i swap the head?
