2AZFE Differences from 05-06------07-08 Block/Head
I searched and found no real evidence in differneces in eninge years. I just bought a 2005 block and 2006 head. I know they will fit but I will change out parts such as Timing cover, valve cover, pulley system, upper oil pan, intake manifold from a 2008 engine. All the parts are still the same correct??? onyl the maf and ecu are different?

05-06 blocks are 9.6:1 compression while 07+ blocks are 9.8:1 compression. Also the 07+ engines make peak power higher in the power band (and more power over all) so I assume they have a more aggressive cam shaft. And one last thing. The 07+ blocks have oil squirters under the pistons so they can probably run more aggressive timing.

Will I have a problem running the 2008 ecu with a 2006 head/block? It will be a stock head built block. Thanks for your help guys----oh and i will be using Wiesco pistion s 9:0:1 i believe standard bore

I have a 2007 with a built bottom 8.5:1 compression running on stock computer/injectors

oil squirters in the 07+
different size head studs from 07+
different maf but who cares thats not a major deal when building the motor
different compression on the pistons
different oil pick up and pump
the only difference in power is 1whp and 1 tq... the newer motor only has a compression upgrade.. the head is the same.
there is an NCF file that shows ALL the differences.. from what i remember the ones listed above are the most important

Just remember. In 2007 the way cars sold in America are dyno'd changed and most import 4 cylinders lost 5 to 10 HP while our car gained 1 hp. The reality is we gained a lot more then 1 HP and this is shown though the difference in stock dynos between the 05-06 and the 07+.
