I have a 1990 with a 1992 b18a1. Just wondering if it would be a good motor to put money into to fix up, as in horsepower? If not, is the b16 a better motor, as in faster or more powerful?

 

a b18a1 is like 140 hp and a b16a is 158-168hp i whould do a b16a or b18c- b18c1

 

I'm assuming that you have a civic.
It depends on how much money are you willing to spend on your motor.
A b16a would run you about $1200 without labor.
Or you can put those $1200 on a turbo/supercharger.
I don't know much about the b18a1 and what numbers it would put out with turbo/supercharger, but it would be more hp than the stock b16a.
What condition is your current motor in?
If it has 140k+ miles on it forget about the turbo or supercharger.
The motor wouldn't last more than two years. Depends on how you drive it.
You'll be better off with the b16a.

 

how will you be driving the car?
how much power do you want to make?
how much money are you willing to spend to get there?
why did you post in this forum?
do i look fat in a white shirt?

 

sell ur b18a1 get a b16a and go turbo thats what im going 2 do when i get enough $$$$ im in a 1991 hatch back si civic

 

nah keep the ls it has more torque. in stock form and with turbo. way cheaper to fix and buy. then u dont have to run more wires. just my .05

 

You make you good point.
The ls is also good for all motor, if you get another head.
