I am going to turbo my LS motor. First i want to upgrade the fuel system. What exactly do I need to do this? How many PSI can I run on the stock motor with the upgraded fuel system?

 

i recommend Hondata and some injectors. dont forget... tuning is the key.

 

I think that needs to be your title. You say it all the time.

He's right though. You can have the best fuel management out there but if you don't know how to tune it then it wont do you any good. Your engine will fail just the same.

 

What hondata would I need (and where are they sold)? Also, What sized injectors for 12psi max boost?

 

You can purchase hondata from one of the following dealers on this page:

Get 440cc injectors.

 

I would go w/ 550's for 12psi. I run 12psi stock motor everything is ok but its all about having a safe a/f and most importantly running safe timing.
