sti forester engine

ive got chance of a 2.5 sti forester engine complete with 2.5 heads and inlet manifold would this be ok to put straight in my classic type R or would i need to use my 2.0 l heads.

if i used everthing 2.5 ie, block/heads/inlet would i need to change anything on my type
R.

also what injectors come in foresters std the car was a 05plate.

i already have most other needed mod. exhaust/filter/walbra/apexi ecu

Any help very greatful.

Thanks Nicky

AVCS heads will cause you an issue.. would need either the ecu and loom for it or use your heads as well as issues with tps sensor wiring etc

injectors should be 550cc and yellow and be in the same style rail ie. side feed as on the phase 2 classic.. unlike impreza newage top feed.
