Thread: Porting a Gen V

Can and should it be done? Who has done it and what kind of numbers have you seen with it?? I am wondering if I should have it done or not. Also how it would perform with Full size I/C.

Thanks. I will do that. I kinda figured with the difference between the Gen 3 and V that might be one of the unnecessary things to do to it. Ill just change the Coupler, check the fins, change fluid, clean it and dip it.

Edit: Wont porting it make it a little louder though?? It did on my Gen 3

Yeah, I think I should as well. save me some money.

if you buy an intercooler for it, try to get one thats made for a gen V. The gen3 cores will still work with a genV but you lose functional PCV and its slightly more restrictive as it doesnt quite line up properly. The difference isnt huge but its worth getting a GenV IC core if you're buying new.

I was planning on a Gen V full size I/C for the Gen V. I have seen videos of GP's that scream. I just want that whine. My gen 3 screamed but not quite as loud as I wanted.

For porting a Gen V, it's best just to clean up the outlet triangle since there is still a bit of rough casting there, and on the inlet side I filled my egr I wasen't using to reduce turbulance as well as took a few sanding wheels to polish the inlet. Was it nessecary? probably not but any improvement is an improvement and it all adds up in the end.
