Is there a differnce at all in affecting anything using a gsr oil pump and water pump on a lsvtec setup? Iam sure it will see high rpms in the 9000 range. Just wondering if it would be ok to use for my setup. Compression should be around 11.8 give or take.



Also iam going to be putting my engine on a stand soon but need to know what size bolts to use?

 

One more question, will the ls crank be fine to use?

 

gsr and itr pumps are the same(obd2 at least) and it would be kind of hard to build an lsvtec motor without an ls crank, dont u think?

 

u can get a itr water and oil pump from inlinefour.com water pump comes with everything u need belt, tensionor or u can jus get the pump

 

B16A oil pump 53qpm
B17A oil pump 54qpm
B18B oil pump 53qpm
B18C oil pump 75 qpm
B16A water pump 140qpm
B17A water pump 140qpm
B18B water pump 148qpm
B18C water pump 148qpm

LS oil pump ---> ITR/GSR oil pump = straight swap + if you bore it out you'll get better performance?

LS fuel pump ---> ITR/GSR fuel pump = straight swap but after 1995 all Integra fuel pumps are the same?

LS water pump ---> ITR/GSR water pump = straight swap but you need to use an ITR/GSR drive belt because there are more teeth driving it?


from some where on ht i copied it a while back cause i was planning on swap water and oil pump on ls for my turbo setup

 

all the obd2 replacement part numbers are identical for b series oil pumps

 

eh.................lol

Ask the top 10 head Honda builders in the US, they will tell you the same thing!!!

ALL B-SERIES OIL PUMP ARE THE SAME, SAME SHIT, SAME PART, SAME FUCKING PART NUMBER.............FUCKING ALE


For those who are learning, ITR Oil pump is the same as the stock CRV, Civic SI ('99-'00), LS/GS/GSR/ITR motors. Yes, part numbers are different from '94-'95 due to OBD-2 on the later models. OBD-2 have the Crank sensors, whereas the OBD-1 don't have.

 

good info but don't the itr flow better than b-16 or just mainly isn't it better? i know you say that all b series are the same. Juast asking..

 

ok thanks for the help on the oil pumps and water pumps. What about a ls crank vs a crv crank?
