Now my engine has a 130k on it so I was wondering if I could upgrade other internal parts so nothing else goes out. Basically I'm upgrading and making it run better and faster than new or trying to get there.

And this car will be N/A all the way

 

are you going all motor or turbo?

 

I've decided no Turbo, All N/A.

It will be used for daily driving, I plan on keeping it for a while as well. I figure if I upgrade the engine internals it would be basically like having a brand new modified engine.

 

i think it really comes down to which one you want to pay for. if its a daily driver i dont think you will like a full race port on the streets. maybe a street/strip port with a decent cam will hold you over until you can build your bottom end with high compression

 

Bring it to a local shop and get quoted there..

 

how much HP increase would I see with a ported/polished head?

 

theres so many factors from what compression you have to what cam your running to how well it was ported out.
