I have a 97 ITR with:
-JRSC with the 8psi pulley and Endyn stepper pulley
-Hondata 4b
-Comptech Ice Box
-Comptech 4-2-1 header
-Thermal 3" exhaust
-What size injector should I use? I am looking at either the RC 440 or 550 from Importparts.com. BTW, I am planning on going turbo next year to run more power. Will it matter.

 

if you're gonna get a turbo you may as well get the 550's then..otherwise, they aren't required for the jrsc...

 

go with 550cc
