Hi, the engine on my 2006 Scion tC blew up, I don't know exactly why or how, but I'm ordering a new engine as soon as possible. I just need help verifying which of the two options I need to order, based on the manufacture date, if it matters at all.







Thank you in advance! -Jkuhn9

The difference between '05/'06 and later 2AZ-FE engines should only be higher compression, different cams, and the addition of piston oil squirters for '07+

Hopefully someone who has done an engine swap can tell you for sure.

So could I order either option and have no problem with wiring, trans or any other hookups?

Like I said, I'd wait for someone that has done a swap to confirm for sure.

Subb.
I would like to know this information also.
I know 100% the maf sensor is different.

And the data should be on that sticker 10/05 so oct of 2005.
Yes i know you said you have an 2006. Sometimes they make them easlry. So you should be the 04/06

I stumbled across this thread from 2013 of swapping an '09 engine into a '06. Looks like there are a couple differences between the different gen engines but nothing that can't be fixed.

I just rebuilt a 04' 2AZ-FE from a Camry. The 07' up have revised head bolt design that won't fail. 07' up have a plastic spacer in the water jacket to slow down water flow for better cooling. I used my 08' dipstick, cams and head. Not sure if the 9.8:1 vs 9.6:1 ratio comes from the head chamber or pistons because I didn't CC the head but .2 compression is hardly going to change your HP numbers. I do know that almost everyone has oil issues on these engines. Looks like the oil rings and oil relief holes clog up very easily from the two I just worked on. I have seen some people without the oil issue at high mileage and I bet they are using a full synthetic and also regular or early changes. The 04' I picked up maybe had 2 years use after Toyota rebuilt it under warranty and the piston oil reliefs were 100% clogged on the new pistons. I would never install one of these engines without pulling the pistons and throwing a $30 set of rings and cleaning the pistons thoroughly. We have a similar problem on our SR20 engines burning oil after 80k miles. changing to a good full synthetic and 5k mile changes has fixed it for them.

Edit: Also my 04' has squirter rods just like the 08'.

One more tid bit of info. If buying a engine form a salvage yard get the VIN number from the ENGINE not the car. Get a free carfax account and run the VIN. I just ran into a salvage place that tried to screw me twice in a row saying LOW mileage and "A" condition when in fact they were super high mileage and not even the year specified. Another cool thing is you'll see if the engine was regularly maintained if it was taken to reputable shops and/or dealerships.
