3406b turbo upgrade???

The one in the intake that the coolant runs through. When oil starts coming out of the turbo it can cake up on the top and not let air across

 

Thanks, that is what I was thinking, but wasn't sure.

 

Yes, it is. I paid about $1300 for the one I have, no core charge.

 

The only adaptation required is to either replace the solid oil tube with a braided steel hose off of an E model, or carefully bend the existing tube, or adapt the mounting of the waste gate actuator to clear the oil tube. Purchasing the E model tube would be the simplest way to go.

The advantage is that the engine will build boost much more quickly and at lower RPMs. The 177148 is an aftermarket replacement for an E model, and supports 550 hp.

 

I believe so. Mine are both 4MG with air to air, but the bolt pattern should be the same.

I know of folks talking about round port versus square port, but I am not knowledgeable about what has what. @wore out , @SmokinCAT , can you help here?

 

Understood. Best to let folks with more knowledge than me help you determine that.
