    I have a friend who was rebuilding a GSR. Unfortunately, he overheated the engine and didnt notice for about 5 minutes, causing his block to warp, and now it wont start. He already had new pistons and rods and everything, but were not installed. Could he take a B16A block and install the b18C1 internals using the b18c1 head?

    the blocks are not the same
    the b16a has a shorter deck height

    as for whether or not it will work? :shrug:

    if he overheated, i bet the head is warped too

    the pistons should work in a b16 block though

    Pistons WILL work, but if i'm not mistaken on the exact height difference, I believe it is 7 MM....Not for sure, but i know there is some difference

    not directly they wont'. the bore is correct, but they won't fit the gsr rod properly.

    which furthermore supports the fact that the blocks are not the same. deck height is different between b18c* and b16*'s...

    Well, in order for that to be true, you'd have to substitute the * in B16* with an A, since the B16B is the same block as the ITR. Also it doesn't include any differences made by the crank, which could make the deck hieghts teh same, but they aren't :)
