I was wondering if any one tell me the difference between the two motors any specs would be awesome thanks guys

 

I think a better question would be the difference between the two versons of the B18A1, 90'-91' & 92'-93'? The later verson has 140HP while the B18B1 has 141HP. So I've been told.

yes i would like to know why the 94 b18b has 142...whats the difference? i thought the engines were pretty much identical

 

you answered your own question. "pretty much" = operative words

they added a solid 6 more lb/ft of tq... which changes the whole thing. c'mon, we have hondas.

my little doll-size hand wrenching makes more torque than the car the bolts are on...

any more specs would be great

 

one the cams in the 94 up are a little bigger (exhaust) ,94 up intake manifold are more smoother,other than that its the same


that is why i use the 94up cams/im/tb on my 93 b18a

 

I should get same if not better results if I run the 94 and up cams/im/tb on my 90' B18A1?

yea you will i noticed a differnt in mid to top end power

 

The cam lobes on the B18B on the exhaust cam have a .2" larger cam lobe height, along with the freerer flowing IM. The 10hp difference between the90-91 to 92-93 B18A's I think has to do with the switch from OBD-0 to OBD-1, probably better fuel management and things.

 

Also, the OBD0 B18A1 has a 4-1 exhaust manifold where as the OBD1 has a 4-2-1.

 

What is the code for the head of a B18B1? And if I buy one that is complete would I still want to use my 4-1 exhaust manifold?

 

Aww P75. If I bolt up a P75 onto my B18A1 block, and leave them both all stock..... what kinda of HP & TQ gain would I expect?
