are b series motors are interchangable.

example: b18 from 93+ into 91 teg, or b16 into 91 teg, or b20 into 91 teg.

anyone know?

i've found a gullable slack jaw'd old man run'd junkyard, i want to get a newer b18, like the 93+ integras, 10 more hp i believe.

 

get me one for a good price an i will tell you...

yes they are, you will just need to swap over wiring. but you probly wont get anymore hp unless you swap over ECU's too, which is a complete bitch...

 

do the 91 and 93s use different fuel injection systems?

 

yeah in 92 they went to OBD1 system. but the engine its self is about the same, think it has a couple extra sensors/emssions crap. just swap your intake manifold and i think you will be fine...

 

the non-vtec b18 motors that have 10 more hp are the 94+ ones.

90-93 = b18a
94-2000/1 ? = b18b

 

Johhny you best bet would be a longblock B20z, and just swap the intake manifold from your B18 on it..

 

Where is this junkyard your talking about? I wouldn't mind getting a good deal on a b-series motor.

 

Almost all b's are interchangeable The B-20 and B-21 in the 3g prelude are not interchangeable. there more easily swapped with H-22's than other b's.

 

Correction:
90-91 B18A=130hp
92-93 B18A=140hp
94-?? B18B=142hp

 

what car is b20z from? crv?
