I need help im planning to turbo my 93 240sx with a ka24de. I need to know about how many pounds of boost can i run on stock internals. The engine has been very well maintained and has never missed a tune up or oil change.

 

you can safeley run 8 pounds of boost on 91 octane with 9:1 compression pistons if you have 10:1 pistons you can boost like 6 pounds if you run race gas you can run higher boost just make sure you run a good sized front mounted intercooler. just remeber more horsepower= more broken parts.
