all factory 100kw 4age's run 232 duration cams. the ae86 4age (and supposedly late aw11) run 240 duration cams - are 0.1mm greater in lift. suppoesly good for another 5kw though.... (i have a set i'm putting in a rebuilt/ported head that will find its way onto my ae93 when i get boored and have the time)
budz--> Big hunt to find cams? Nah...they're very easily available. Anything from std replacements up to huge lift, massive duration ones. Most of the cams on the AE92/93s are the same (4AGEs), but I have seen some with the earlier model (AE86) cams on them. A good upgrade is to use a camshaft of around 260 degree duration, and about 8.4mm of lift. This will enable you to still use your std computer. Pretty decent gains for just a camshaft change too. Around 15-20% increases are quite common.
