i want to do an ls turbo, but i cant find a good deal on a b18b..

i had a shop tell me he could get me a full b18a swap for between 600 and 800..

so should i hold off and wait till i can find a newer one in my price range or is the b18a a good motor?

 

they're the same thing basically. the important question is what car is this going into?

 

92 civic and up = hydro tranny, 92 and below (b18a swap) = cable tranny. if u got a newer car get a b18b for simplicity for ur sake it'll swap right in. but there is no difference between the motors. minor if any.

 

the b18b (140hp) make 10 more hp than the b18a (130hp). the headwork on the b18b is a hair better. So id personly start with a b18b.

 

Im not positive but, i think the b18a doesnt have a crank case breather( you know the little canister next to the oil filter)

It does

 

b18b has very slightly better cam profile and intake manifold, hence the extra 12 hp.

also, theoretically a newer b18b will have less miles and less wear

 

A b18b top end is dirt cheap so go with wich ever is in the best
shape for the least $.

 

ive also been hearing alot of shops telling me that obd2 is not very good, and that its going to be harder to swap an obd2 into an obd1 car..

 

if your going LST then get an obd 1 motor. you'll be able to chip the ecu for it without getting a jumper harness

 

and the obd1 motor is the b18a.. correct?

 

90-91 is obd0 b18a1, 92-93 is obd1 b18a1. 94-95 is obd1 b18b1, and 96+ is obd2 b18b1

 

theres no differance between the 2 motors
blocks are the same
b18b has a better intake manifold and bigger cams
but the 2 motots are the same

 

so my best bet would be to try to find a 94 or 95 ls..

 

92-95

 

yeah but 92 and 93 are the older ls, b18a..

so if i could have my first choice it would be 94 or 95.

 

either or would be better. just try to find one with good compression and low miles
