2012 to 2006 motor swap

As title states. Looking to swap a motor out of a 2012 tacoma to a 2006 tacoma V6. Any known issues?

 

as long as you use the 06 exhaust manifolds you will be good.

 

Just curious, but how are they different? The frame?

 

2012+ v6's had the addition of the smog pump which injects clean air in to the exhaust manifolds to aid in catalytic converter efficiency during cold startup. your 06 doesnt have this system so the manifolds would be left with holes in them, though you could just block them off.

 

Also the passenger side valve cover should come from the 06 as well

 

We have a whole 2012 parts truck. Could we use the 2012 manifolds on the 06 ,if we use the 2012 ecm ? Manifolds are rusted out on the 06. We're going to swap the whole 2012 motor/tranny into the 2006 truck

 

Red truck is the donor. Total loss 140k miles. Blue truck is the recipient 2006 190k, new frame , good title, blown motor. Title in hand on both rigs.

 

Are the tail lights and hitch still good on the red truck?

 

I need the hood scoop insert off that red truck!!

 

Just don't do it, unless you swap everything!

 

I spent alot Of time, I mean months deciding on an engine for my 2006. A 2012 will have the emissions issues, the work around and 'fixes'... They don't work. If you replace everything... May work, because basically you will have a 2012 truck on 2006 frame. But, hay, you have both trucks, so go for it, I would! just know, it's not just an engine swap. The best engine for that truck is a 2007-2009 1GR-FE from an FJ with VIN starting with 'J'. That means totally compatible and made in Japan.
