i just bought a b20b or z motor from h motors online and they ask me do i want the high compression or the low compression. i said the high cause i know it comes wit the 146hp so hopfully i wont get dick when the motors gets to my shop. but ive been doing alot of research and i came a cross in how telling if u have the high compression motor or the low one and that u can tell if it has a knock sensor in the back which share the same style plug as the honda prelude. my question is how is the wiring is suppose to work cause i have a 1996 integra obd2a and i know the motor that im hopefully getting is a 99-2001 and i know does r obd2b. and does the distributor have to be swap with my old ls motor.and do i have to use the crv 99-01 wire harness cause i know u can use the ls harness.please

 

i recently swapped my 93 ls with a b20b, i used my wiring harness and dizzy. Now my ls motor had an extra sensor(which i beleive is the knock sensor) in the back next to the oil pressure sensor. the b20 didnt have this sensor at all.. but it did have a "plug" were it would be. so i removed the "plug" and screwed in the sensor. Does that make sense???

 

i used my old intake manifold and left hand side motor mount braket, the b20b bracket fit too low. everything else is basically bolt on.. everything from the ls bolts on to the b20. i also beleive u cant use the b20 harness or dizzy because b20 are automatics!?!?

 

this sounds crazy for saying but wat is dizzy.distributor? i just checked the fourms and one guy was asking the same question and they said that the ls did not come with a nock sensor so its not in the harness so i can leave it unpluged and nothing would happen. off topic any body bought a b20z from hmotors and actually get the right one only reason why i ask is alot of people say they r great place to buy motors and the guy told me you can tell if u have the high compression motor by looking at the intake manifold

 

dizzy=distributer when i came across the knock sensor i had to make a few phone calls to my buddies about this and they didnt have it either on there motors. (ls or b20). so i decided to unscrew it and it screwd into the b20... problem solved.im pretty sure your ls doesnt have it either nor the b20 u ordered. but my ls did.. crazy huh? you know what i think the b20b is the motor u want. i think the b20z is the motor off the old school preludes which is not the crv motor.double check on that. but other than ive heard nothing but good stuff about hmotors.

 

well from my research basically if it comes wit the knock sensor its the one wit the 146hp and i guess sine my ls dosent come with the knock sensor in the harness i shouldnt have to worry just leave it unpluged. last thing alt and crank pully has to be change right because of the b20 crank pully is different. just swap it with the ls motor. oh by the way im also doing the tranny swap just waiting for the motor to get here so i can get started.

 

anybody bought a b20 high compression motor from h motors cause i just bought one and im hoping they wont play me. they bascically said on the forum to look for the knock sensor and the the question will be answer.

yo guys i just got my motor from hmotor b20b the high compression.only reason y i know is because of the knock sensor in the back. all high compression b20 come with knock sensor. hmotoronline is the way to go all the way.

 

dude no worries on hmotorsonline... i coulda told you that i live right next to them and ive bought 6 engines for different projects. the engines were always perfect... if they werent i woulda stoped going back after the first time... i also bought a gsr tranny from them which shifts like if it was brand new.
