#243203 hey i was wondering if there are any other ways beside looking at the serial plate on the block if you can tell if you have a b18c or a b18c5?
is there any other spots with labels or serial numbers on the block???

#243207 Look for P73 on the head. P73 = ITR P72 is a GSR.

Look right in between the header and valvecover

Great things, without it you dont have torque :thumb: :lol:


GSR two stage manifold wins as far as driveability. :thumb: :thumb:

Getting on the freeway, emergency lane changes, pulling out into fast moving traffic... that's why I chose the B18C1 over the B18C5.
