Should I keep my stock IP or possible get one newer off a 6.5? I'm wanting max power with not a lot of $$$.

Stick with the stock IP or get a mechanical 6.5 IP,might need different hard fuel lines if using 6.5 heads and injectors?

These are not high HP engines 200HP is about it stock.

Might be better off with a cummins or Dmax.

So Holset turbo, stock pump, stock injectors. What about the ebay intercoolers? And also you wouldn't recommend anything over stock injectors?

And 200hp will be better than what I have now N/A just ain't cutting it for me. Cummins is my dream but that's a lot of money that I ain't got.

Would you recommend the HX35 or HX40 for value and power?

Mine is an ebay intercooler much like ebay item #:
140916704706
with something like piping kit#190798616114

Not sure how to tell you Holset HX40 any other way than the 3 times I have already?

Stock injectors are plenty good enough on a 6.5-not sure about the 6.2 injector output?

I'll do a little more research on the injectors before i decide on what to do. I know the 6.5 probably has bigger injectors than the 6.2. And I know more fuel and air usually equals more power. That's why the turbo and injectors are on my mind.

The reason i keep asking about different Holset turbos is that i can get a 12 valve turbo for less than $200, which i believe is the HX35 correct? Any idea on what a good HX40 may run me?

Those are basically the intercooler and piping kit I was looking at, so thanks for that info.

There are new chinese knock off HX 40's available,some research into them might be worth the effort.

I think there are 2 different 6.2 injectors,fine thread and coarse thread-the fine threads are the same for 6.2,6.5 and are short body to make room for the turbo,but the coarse thread might be long body only-I forget at the moment,more research required.
