got this off honda tech:
PS: I use up about 4k doing a B20 exchange, and another 4k turbo, running at about 250WHP, think about it
B16
These may be found in the JDM SIR and SIRII among other JDM cars, which I do not assert to know all of which it came in also as the USDM 99 00 SI EM1 and the 99 00 Canadian SIR.
Pros
160 hp stock
High RPM power
Fairly inexpensive
Good transmission
DOHC VTEC
Cons
113ft/lbs torque bit more than a D16z6 stock
Without knowing what you are looking for you may be able to end up with a high mileage JDM model
Under 4k or so it feels just like a D16
B18B
This is the motor in the non Type R and non GSR Integra.
Pros
Good torque for a 1.8L 127 ft/lbs
Inexpensive cheaper than a B16
142 hp more than any stock D series
Boost heads love them
Cons
No VTEC
Longest B series transmission
B18C1 or JDM B18C
These come out of an Integra GSR.
Pros
Good Hp and TQ numbers 170, 121 ft/lbs in that order
DOHC VTEC
Tons of potential
High revving
Cons
Expensive
Becoming moreso as people keep scooping them up
Slighty longer tranny than the ITR and B16
B18C5 or JDM B18C
This is found in the Integra Type R. IMHO this is the best exchange for a Civic.
Pros
GREAT HP and TQ numbers 195 and 134 ft/lbs
High revving
Hand built motor from Honda
Optional factory LSD
Best transmission for a B series from the factory
Red valve cover
Cons
EXPENSIVE
If JDM ITR can be used, the 36mm axle 32mm hub problems occur
B16B
This is the motor found in the Civic Type R found all over the world.
Pros
185 hp 117 ft/lbs
High revving
Good top end power
Red valve cover
Cons
Expensive nearly as much as an ITR for lower performance
Very little torque still, have to rev the motor to make power
B20
Pros
Great torque 133 ft/lbs
good increase motors
inexpensive
B20z=146hp
Cons
Thin cylinder walls
Have to peice together a exchange for a Civic can not drop it in with a B20 tranny
Won't pass BAR light truck motor in a car
Low hp in the B20b 126 hp
H22/JDM F20B
Pros
200 hp
H22=156 ft/lbs torque
F20B=145 ft/lbs torque
Great torque
DONT WEIGH THAT more THAN A B exchange..
honda tech.com/zerothread?id=684550honda tech.com/zerothread?id=684550">honda tech.com/zerothread?id=6845.
Cons
Harder to install than a B/D motor
transmission feel is indistinct IMHO
Less information out there for the exchange aka, less experience as they're less common
Price of exchange is comperable to a B18C5 after everything is said and done mounts, etc
K20
This may be found in the new EP3, the RSX base and Type S also as other cars across the world RSX R, etc, and this is the future of the exchange IMHO. there's a writeup on installing one of these in one issue of Sport Compact Car magazine June 2004 I think
Pros
200 hp 158 ft/lbs torque RSX R
I VTEC
Respond well to screw ons
6 speed transmission
Most have low miles
Cons
Still super expensive
More hard exchange than a B or D
