I was wondering how much an m103 block can be bored out until a diesel cam is needed?

Also would an intercooler that's 28 X 6 X 3 be sufficient to enough to run 5-9psi w/ a turbo that has an .50 A/R rating?

What are some quality turbo accesories I should look for boost guages, fuel mapping etc...........


I'm trying to stay on a budget so boring out my block is my only option unless it's cracked. I've searched and searched the forum haven't got too many questions answered for what I'm trying to figure out. Hopefully I will have money soon for this project going to cost me big
