Default Need Help: VVT=AVCS

I know about AVCS and such, however, there is a guy locally selling an 08/09 Forester XT long block. He says it has VVT, which i interpret into avcs. SOOOO, did subaru switch to VVT on the new cars or does he mean AVCS. I dont wanna buy a block and heads that i cannot use. I have an 04 STi at the moment. Any response would help!


Thanks everyone,

Garrod

you wont be able to use the vvt or avcs regardless....if this engine is going into your 04 sti.....your ecu is different

also....the whole intake manifold and throttle system is different

I already have another built 04 STi block. I was mainly going to get this for the heads. I am also using a intake mani from an 06 2.5i. I am also going with a standalone autronic ecu. My car is equipped with avcs, so i dont see why this wouldnt work. Isn't vvt a toyota thing?

He meant AVCS, some call it vtec, some call it vvt, some call it avcs, whatever floats their boat.

It's still AVCS

You should be able to the run the heads on your car (unless subaru made something different)

Thank you sir, that is what i am looking for. I just need to find some evidence, before i invest in something that wont work. I am pretty sure it will, but, i am not familiar with the newer subaru's.

It is my understanding that AVCS and Toyota's similar VVTi only affect timing, they do NOT have a mechanical means of having followers use a completely separate higher lift/longer duration lobe on the cams themselves which is what Honda's VTEC does.

Thanks everyone,

Your only worry should be if it's dual AVCS like the 08 and newer STi's. You can get any single AVCS ECU, with the exception of JDM setups, to work with another.

I think it'll work if it's still single AVCS. Dual AVCS, not without the corresponding ECU from the new motor.

Yes, the AVCS solenoids and connectors are the same. You would be able to use your STI cams and solenoids if you wanted to anyway.

In fact, you would be able to use the whole motor as long as you took your wiring harness since the main connectors are different. Even with the plastic manifold, as long as you had a turbo/intercooler to work with it. Those plastic manifolds are really great if you want to flip them around, too.

So, what if he decided to swap the cam gears from his STi onto the new heads?

Or...what if he swapped cams and cam gears?

What are YOU on about? The holes are from SOA punching them into the block to render them useless. Please think before posting. KTHXBAI.

Yes PANG, i know they had holes(drilled by subaru), but i just got a complete longblock with, complete heads, all sensors, oil filler, dipstick, all pulleys, cam gears, front and rear timing covers, water pump, oil pump, tgv gaskets, coolant crossover, oil pan, and maybe some good internals. I didnt buy this for the block, i already have a machined one at home, i got it for the heads and accessories. Not bad for $200.

You are just sad that you snoozed, and you losed!


Thanks to everyone with helpful responses. **** off Stibungydouche
