Re: Need help from turbo 3.4 guys out there
Since you are running a Megasquirt and can set the rpm limiter to whatever you want you should know that the 5vz probably has similar rods to the 2rz and 3rz. They can take lots of compression force and handle boost very well however if you raise the rpm limiter much they will likely come apart. No one really knows for sure but it's probably weak rod bolts in these engines that make them self destruct if you raise the rpm limiter much. I think stock the 5vz limiter was set to 5600rpm.
