New owner of a 2.7 l 4cyl 5 speed 4x4

I know the 2.7 had a timing chain and gets a few more MPGs better than the 3.4 what else is a benefit of the 2.7?

Also which engine is most reliable?

 

Thank you for that video! Is the 3.4 an aluminum block?

 

Sorry I have a 2002 first Gen was the 2.7 liter different that generation. The video shows the second gen

 

Completely different from a 3RZ

 

Yeah, you'll get that a lot.

 

oh no im sorry bro, didnt even notice this was the 1st gen thread

 

the 3rz is a great engine with proper maintenance and care the engines see over 200k only common issue is the heads are a little weak besides that by far my prefered choice over the 3.4

 

The 3RZ has a stronger bottom end but that doesn’t really matter unless you’re adding boost. IMO the 3.4 is usually more reliable in real-world applications since you don’t have to worry nearly as much about the valves going out of spec or the head(s) warping.

 

For what ever reason the Exhaust manifolds like to crack. Not really the engine but good to be aware of.

It all comes down to the history of the engine some people can ruin anything.
