My question is what exactly different from a gsr engine to an ls. I know the LS has a lower output water and oil pump, the crank is not zero balanced, the stroke is up like 1.6mm, the rods and rod bolts are not as strong, LS has no oil squirters, and no crank girdle. So how balanced is the LS engine. Also is there any other differences that I didnt put down. Any differences anyone wants to put would be appreciated. Thanks J

LS's dont have Vtec cams, or Vtec solinoid

 

The entire head is different

 

The LS also doesn't have a knock sensor.

 

My bad I meant just the bottom end. I know the you cant bolt a VTEC head straight up to the LS, I know the LS dosent have the oil passage to the head. I just want to know whats the differences in the block not the head. Thanks though. I heard the gsr and type r bearings have a silicone overlay over them or something.

 

a gsr block will have a block girdle

 

Thats right...totally forgot that. It is like a half-girdle.

 

I know the GSR has a girdle but are you saying the LS has a half-girdle or the GSR does? Also on the bearing part I think there teflon coated(vtec 1.8). Can anyone confirm on that?

 

the GS-R motor (B18C) came in integra GS-R's, and the LS motor (B18B) came in integra LS...hope i cleared that up
