1.8L Question
 

Am I correct?
B18C1 & B18C5 are the same block.
B18C1 & B18C5 have the same rods.
B18C1 & B18C5 have the same crank.

Im looking at the shop manual and per the specs it all looks the same. Is there a difference other then the head?

C5 rods and cranks are a bit lighter from the factory(nothing you will notice) They are the same length as the C1's so they are interchangeable.

yup! ^^

The ITR crank is also balanced closer to 0 than the GSR from factory. Used one in my NA build a few years ago and took it to 10k a few times with no problems:tits::tits:

Thank you that is what I though.

C5 is just a hair more refined in many aspecs, but as far as specs, totally interchangeable

Not exactly true.
The type R crank is heavier.

ive heard this as well, but dont have any proof to back it up.

x3. ive heard that the gsr crank is lighter. but ive only heard. and ive heard alot of bullshit. lol

nice
