The 4JB1-TC in my jeep now has 15,000km on it with no problems.
Nice family vehicle.
So now I'm starting to get "itchy" again and looking for something to build. I just bought a
1999 Dodge Dakota 4X4 and have been measuring up the Isuzu 4HF1 sitting outside.
Anyway thats another story and not what this post is about.
How much turbo boost can the 4JB1 take? This one is set at 8 PSI, how much can
I crank that up and what other mods would I have to do?

Thanks
Randy
