Hi im driving a 4g15t so i was thing swap the 4g15 head with the 4g92 mivec head. Is it possible? I search from the forum earlier some ppl say cant but need to mod, but they didnt say need to mod what to get the mivec head to fit to the 4g15 block. Oh by the way, my 4g15t was sharing the same head gasket with waja 4g18p.
