My buddy has a 93 CTD, I not sure what hes got done to it but I know its turned up. He wants to put injectors in it but hes afraid of the miles. 180k Is he safe to put them on? ???

 

That engine is just broken in. Go ahead and put them in there man. ;D

 

What size would you put in it

 

Depends. Does he have gauges? Personally, I'd go with a set of 370 Marine injectors but I'm a little on the extreme side ;D. I really don't know about injector sizes for the 12 valves. Maybe you could try the equivalent to a step 2 injector for a 24 valve. Don't know what size that is.

 

I think he wants to put 285s in it, or would you go bigger. Anybody that knows about injectors on 12valves

 

What about the Prince Of Darkness injectors i heard of some guys running those there supposed to be really good!
