ok so my last ls blew ... i made a thread about it , it was smoking did a compression test cylinder 3 was on 60psi 1,2,4 were at 150 so i didnt want to deal with the headech anymore bought a jdm b20 low compression at jdm engine depo but i have heard jdm engines dont have a crank positionin sensor and i need to change the oil pump to the b20 because if not the car wont start ... is this true ? and i would like to know what else
do i have to switch i also heard my block dosent come with a knock sensor ... help is appreciated thanx in advance

also will the jdm b20 be a drop in direct bolt on to my 97 teggy ?

 

what year integra is this going in?
if your car is 96+ and is equipped with a crank mounted crank sensor, you can just swap your pump and sensor over. use your ls distributor and intake manifold. low compression b20's with the p3f pistons won't have a knock sensor. however, high compression b20's will

 

its a 97 integra the b20 came with a lower mounted intake mani so i dont have to switch .. so i dont need a knock sensor ?
