i'm running a t25 at about 6 psi on a d15 del sol. i'm going to run it through a 2G eclipse stock intercooler. What size intercooler piping should i use. Also, what size downpipe do i need to make. also do i need to run different plugs or gap the plugs different?do i need to turn the dist. any to retard the timing? thanks

 

so you are already running? and you don't have fuel management? (injectors,FMU,fuel pump) type stuff? You are just going to run 6 pounds untill it blows up? You need to read up just a bit more. to answer you questions
1) 2.25
2) 2.5
3) NGKs or something colder
4) some come pre gapped, but (.028-.030) gap
5) retard the timing

 

no i am currently putting it on. i have larger injectors and a safc. i just wanted to know what plug number to run and how much to retard the timing
