my motor is b18c change this anything or is tha same diameter with that you give me60mm (2.36").
yes i have type-r motor b18cthats good for what you have, your exhaust is holding it back if you have a 3" 70mm one. do you have a Type R motor? Cause no chip would give you 30bhp
really? stock type R is only 2.25" i thought exhaust diamiter was dependent on build and WHP.I'm going to take a guess that since he is measuring torque in kg he is not local, so his b18c is the type r version, not a b18c1. If this is the case you should look at getting a 2.5 inch exhaust.
Okay, i suggest a ITR B pipe or 60mm exhaustyes i have type-r motor b18c
