Just to clarify, this is the first USDM car to have the AVCS. JDM versions have been using it for a while, including the naturally aspirated engines.murley said:This will be the first to have the Active valve timing also which is a very kool upgrade.
Oh ok, I hadn't realized that they had made internal upgrades to the motor (don't know what I was thinking!). :lol: That sounds good, though.91TB78 said:No..there is no history behind this engine.
However, it should do as well, or better, than the EJ20 in previous STis. The reason being is the semi-closed block, forged pictons, etc, etc. The internals look up to snuff for mods.
VVT will be very nice! None of my cars have it, yet, ( :roll: ) so I am looking forward to finally getting one with it!murley said:After having talked to my Subie rep, I think that the 2.5 in the STi is almost the same block as the standard 2.5 they use in everything else besides the few modifications made with the closed deck and all. This will be the first to have the Active valve timing also which is a very kool upgrade. The 2.5 that they use in everything else has been a great motor! The biggest benefit, and probably the biggest reason they decided to use it in the STi, is that it has Great "low-end" torque numbers. It pushes much harder at low RPM's than the 2.0. That plus the 6 speed tranny should actually blow our minds... It's gonna be fun.
