my friend built a b20vtec and he used a b16 oil pump.. is this a good idea or should he upgrade to a type r or gsr? cuz his vtec isnt working either. but it has 80 psi before vtec..

 

b16a pump is fine, his lack of vtec lies somewhere else

 

i know gsr and type r have the same part #

 

well we've tried 2 differeent b16 heads.. one was on a b20vtec and worked great.. and the other one he has is on the car now and does work.. tried 2 different soleniods with pressure sensors.. have a oil pressure gauge hooked up.. both soleniods clicked when saw power.. but when the car was on aand you gave them power there was no difference..

 

my b20zvtec has a stock b20z oil pump and does great

my b20bvtec has a stock b20b oil pump and does great too

 

B20, OBD2 GSR, and Type-R are the same oil pump, same part #.

 

Early gsr pump does not have a mount for the crank angle sensor. Other than that, it is the same as the obd2 pump. Stay away from the b18a ls pump.

 

itr/ gs-r oil pump
p/n 15100-p72-a01

you might as well get the water pump too (has more teeth)
p/n 19200-p72-013

 

Weird thing is the gsr oil pump was more expensive than the type r oil pump from acura.

 

Yeah this has always been an unsettled debate. IIRC, the obd2 oil pumps are all the same for b-series, they were revised flow over the obd1 and they all have the stiffer pressure release spring, but the obd1 pumps had difference between the LS/B20 pumps and the GS-R and Type R pumps. pretty sure this is correct. And yes the obd2 have the crank fluctuation sensor and the obd1 do not. You have to use the lower timing cover from the same generation OBD.

 

Or take a dremel and make your timing cover work.

 

The obd1 pump is about $30 more than the 0bd2. Other than the angle sensor provision, the pumps are identical. Makes no sense but I only use obd2's now.
