is there any modifications used to put a B16 oil pump onto a b20 block? im trying to put it on and it wont slide all the way on like my stock b20 oil punp does. Another question is can i run b20b oil pump and a gsr water pump?

 

use GSR/ Type R/ B16 for ur oil pump, otherwise you mite not get adequate oil pressure during VTEC

 

I have a gsr one and it wont slide all the way on, but my b20 one slides on perfect..should i force the gsr one on? i dont know.

 

Yah, force it on with a hammer for 2 hours.

Did you check what is not meshing? Is the oil pump gear lined up right with the crank?

 

hell yeah i did, but ill go and try it again tomorrow and look real good...dam i hope this crap goes on.

 

b20 oil pump share the same part number as vtec oil pumps, therefore its a vtec oil pump. no need to replace it for the same pump

 

I'm sorry but I do not believe B20 engines share the same oil pump as VTEC motors. Someone correct me if I'm wrong but I think that guy above me is full of ****.

 

OBD2 B20 oil pumps share the same part number as the VTEC oil pumps. They tend to be a bit cheaper too.
