Can anyone tell me which STI models (JDM and otherwise if applicable) have the variable timing on them? My friend is after an STI enginefor his rally car but that variable timing setup wont work with the Haltech hes using, so we are trying to pin down what year engines to avoid.
Thanks

 

European and us JDM models have VVT in them.. to my knowledge in all New Age STI's to date

 

Do all bugeyes have them? Whats the year of introduction of the AVCS (i forgot the name of the system when first posting).
Its pretty much all JDM engines we get to choose from.

 

Think so - the UK engine has hardly changed since the Euro-spec STI came out in '02.

For '05, the JDM STI has AVCS on the exhaust cams too - previous models have it on the intake cams only.

 

Basically all STI since 2002 have had AVCS
