Why is it that people are going with the B16 dohc engine instead of the b18’s??? I’ve heard of a lot of people swapping a b16, why is that? why not a b18??
first off, which “b18” are you trying to compare it to? a b18a/b or a b18c engine? because as i’m sure you know one is vtec, the other isn’t.
the main reason why people swap in the b16a is because its a really cheap way to get vtec. Say $1000-$1200 for a b16a compared to $2500-$3000 for a b18c. Of course the b18c engines have more power, but still, they are twice the price.
Which would be cheaper, a B17a or a B18c1? Which one would be able to produce more power. Would a b17a turbocharged engine be able to keep up with a b18c1 turbocharged engine?
Both are comparable engines although the b18c1 is going to have more torque. Both engines can be built for a lot of power whether normally aspirated or forced induction.
I think both are going to cost around the same price if both are in the same condition. But considering they only sold the b17a in the US and only did so for two years it is hard to find one in good condition for a good price.
obviously the turbo b18c will be better than the turbo b17a----just right off the bat because of displacement differences.
the b17a is 1677 cc while the b18c is 1797cc. As i’m sure you know an engine is just a big air pump—the more air you can get in and out the better----larger cylinder volume is one easy way to do this.
but there is more to think about as well. the b17a will have a slightly better rod stroke ratio, and lower compression, which means you might be able to run more boost.
if you want a good specific answer you need to ask specific questions (eg. give us details about how much you want to build each–or if you just want to turbo the stock engine…)
like whitey said, both are comparable in price. I paid $1200 for my b17a engine with ecu (but no tranny), oh, and its got 125k miles on it. They are rare, so for that reason alone i’d say it’d be easier and possibly cheaper to get a b18c.
thanx for the advice everyone, I think i’m going to go for the b17, just because not many people go with that engine and because it’s a lot more rare than the b18c.
well, you should be able to find one (as i, and a few other members have been able to), but its not gonna be as easy as finding a b18c, and unless you are super lucky and find a low mileage one (which there are very few of) you’ll want to dump some money into it for a rebuild. Especially if you are planning on turbo.
You don’t want to mess around with turbo, do it right, or you’ll regret it later.
good luck on the search for the blacksheep engine!
Keep in mind that a B17A motor is just a stroked B16A motor which makes the same amount of power and only 4 lb/ft more torque.
You can pick up a B16A for a lower price which contains about the same potential as a B17A1 motor.
amen to that, you can get a b16 swap which is the engine/trans/and ecu for anywhere between 1000-1300… if you wanna turbo you can sell your tranny off the b16 and stick the one on from your b18a. just a thought
B16?
I just bought an integra so none of this talk about b16’s, b17’s and b18’s is making any sense to me. Could someone fill me in because I want to try to stay up to date about engines because I am looking at replacing the one I have due to high mileage.

you wanna keep a vtec tranny on a vtec engine because of it’s close gear ratios

unless you’re turbocharging, in which case, as previously mentioned, the LS tranny with its taller gearing will allow longer spool for the turbo, thus making more power. sometimes it’s not all about VTEC.

good call
Keep in mind that a B17A motor is just a stroked B16A motor which makes the same amount of power and only 4 lb/ft more torque.
the lower hp and tq numbers are based on a 9.7 cr. if the the b17a had the same stock cr as the b16a then we’d see an increase in hp and tq, more like 165hp and 123lb/ft; apples to apples. with the physical dimensions of a b17a you get more torque than the b16a and a better rod ratio than the b18c. i think it’s the perfect compromise. but that’s just my opinion.
so the best v-tec would be a b18a bottom and a b18c1 or c5 head. the bottom would have to get new rods and pistons. the top should get new cams. (jun for me baby) and keep the ls trany. dont put the v-tec trany on. so is this some where in the ball park?
no if you do this, N/A motor. you should be looking at what kind of gain? i know it will not be all that much. what if you took it a step further and got the drag turbo kit and put it on. now what kind of gain? or is putting on the turbo a bad idea for the ls/vtec. i know that you need the rev lim. and all that junk. but what about the ecu and getting it chiped??? well enough with the questions. 
I always like the b16a swap thats rebuilt… I got a b16a swap for 1000 bought ctr pistons, jdm itr cams and valve train, toda cam gears, got my head ported, and had my ecu chipped… I am not sure what hy hp is because I had to wait till after the holidays to tune it … but I raced a stock type r and when I shifted into 4th I was about 4 car lengths away… it cost me about 2500 for the whole swap and work… also I upgraded to a itr intake mani and a ported tb … just aa thought
I bought the itr cams, valve train, tb and intake mani seperate so factor in another 1000 I guess…
