ok the blocks a b18a1 with a b16a3 oil pump and timing belt along with the a3 b16 head. if i use the b16a3 timing belt and oil pump shouldnt it go on? it wont at all ive switched the ls and b16 water pumps out too and same ****? wtf

 

I think u have to use a gsr timing belt.....

 

i always though u used the belt for the same water pump on there.

 

i think i has to be a gsr belt and you need to run the gsr WP with 22 teeth.

 

b16 belt way too small-type r belt (not sure if gsr will work with b16 head) with b16/b18c water pump.

 

b16 block has a diff deck height.. belt will be too short. i think you use ls water pump youuse ls timing belt. you use gsr/itr then thats the belt you use

 

you need a 1.8L Vtec belt.

B16 is too small, wont fit, as you now know

 

dam i though people used the b16 belt, well **** looks like ill just go ahead and get a ls.

 

get the ls water pump too. and you shouldve gotten a type r/gsr/b20 oil pump instead of the b16.

 

Gsr head, b20 block with itr oil pump and gsr water pump. My gsr belt fit just fine.

 

whats wrong with the b16 oil pump?

 

if u use the gsr WP then u use the gsr timing belt, if u use the typeR wp then u use the typeR belt, use the belt that matches the WP.

 

^--- those are the same belts and waterpumps. b18c pump = b18c belt : b18a/b pump = b18a/b belt. There is a reason as to why they are different. Go with gsr since you already have the pump. just my .02

 

in response to mycrx7, im pretty sure gsr/type r/b20 flows more than the b16 oil pump.

 

GSR/b16/typeR water pumps are the same 22 tooth pulley. Use Gsr/typeR timing belt. LS water pump is a 18teeth pulley so u have to use the LS belt. The 22 tooth waterpump and GSR/Type R belt is the best setup cuz the LS setup will have a little more slack.
