ok guy i'm really needin help here, i bought this motor of a guy which he says it is a b18c,but i cant tel tell if it is a b16 or wht, (engine code is grinded off it ) so ive stripped it down to the bare block, i have pr3 pistons and rods, head says p72-2 (obd0,1,2?)and cam shaft pulley's say's pr 3 also, how can i tell wht i actually have??? b18c? or some crap all jst put together? cheers guys much appreciated

 

b16 block with gsr head

 

Hey i'm on my other user name now lol, are u defo sure? i have the wrong ecu n every thing for it not lookin good. is there no way u can tell by casting marks on the block , cause i was thinkin i could be a b18c but with b16 runnin gear in it? or is tht not possible?

 

c'mon man some 1 must know here? i think weak squad is right but i need a few other opinions.... and maybe wht i should do with it

 

If the rods say PR3 and when you took off the head the pistons were in line to the deck height. I believe the rods would be too short to make enough compression in a B18 block to actually run. Just like what weaksquad said, you have a b16 bottom with a GSR top. I'd say try to get your money back for that torque-less POS

 

just look at the water pump side.. easiest way to find out. if the block surface is about 1/2 inch taller than the top of the water pump, then its a b18 block. if the surface of the block is level with the top of the water pump, then its b16a.. hope that helps

 

There's a good chance the engine is stolen if the marking are ground off. If you knew this before u bought it shame on you. If not rhen don't pay attention to my post.

 

pr3 rods means b16 crank or pistons sitting low in the block.
