b16 vs b18
I am having a very hard time deciding which swap to do. I've searched so much my brain hurts. I have a 95 civic coupe ex/si and i plan to put either a JDM b16 or a b18b in it. This swap is going to be done next week so i really need to decide. I am not looking for an all out race car but a good street car and daily driver that i will ocasionally take to the track. I plan on staying N/A. For the longest time B16 was what i wanted but since its a street car the torque of the b18b is appealing. Any input would be GREATLY appreciated. I know this is MY decision but i just want to get some info from you guys.

this topic has been talked to death do a search
if you like rev high and hard and like to shift alot B16 is the way to go. you need 92+ octance to keep it going.
if you like to great daily performance and saving money at the pumps B18 is the mature feeling motor.

Go to Honda-Tech, you will be overwhelmed by the discussion.
Both has its merits, it is a tough call.
I personally love to rev, I love the high pitch engine sound. Cause if you go NA but can't rev, that really suck.

I've spent hours searching on Honda-tech.com and hondaswap.com but am still indecisive. I'd really like to go for a ride in or drive an EG coupe with a B16 and another with a b18b. That would be the easieset way to make up my mind.
PunkInDrublic what do u mean "unless you have a b20... in which case its not a problem"?

correct me if i am wrong but a b18b has a redline of 6200 and with a b16 tranny it will rev @4000rpm doing 120km/h... now would reving that high all the time not reduce the life of the engine meant to rev alot lower all the time?
just wondering

i agree with BBarbulo.
B18 is cheap and just b/c its a non-vtec motor it dont mean that they dont have MODS for it....
they have tons.
B18 is nice to boot around on the street, pretty torquey
but comparing it to the track where a B16 has more pulling power at 5200RPM since its a JDM motor, it will not fall flat on its face whereas the the B18 will
since u mentioned that u want to track it.
the answer is simple.
B16A
unless u go B20 CR/VTEC - if do go this route, build it up slowly and not half ***'d

also remember jdm motor may have higher compression then there usdm counterparts but they will have been driven like we drive d16's here.... that being extremely hard... so a jdm motor with 50 000 kms might have wear similar to one that was well driven at 150 000 kms

The B16A tranny gearing is far too short for a non-VTEC motor.
One of these reasons is mentioned by zc_hatch
A B18B will perform just fine with a LS tranny, especially on a road course or daily driving. You'll also be laughing all the way to the bank with how much $$ you save on gas. You'll be able to cruz 140 @ 3500 rpm prolly get
If you want to go shorter gearing, GSR is on the borderline of too short. so thats as far as I would go.
I've seen a B16A tranny and a GSR tranny mated to similar non-VTEC motors and the B16A tranny runs out of gears way to quickly and is easily beat by the longer gears.
Shifting a B16A tranny on a non-VTEC motor @ redline will drop your rpms to 5800 which is already past peak horsepower on a non-VTEC motor.
so when you accerlate you're using the part of the engine curve that begins to slope down.

well you sacrifice fuel economy for performance or you build you a hybrid tranny with a long 5th gear. but who are we kidding, we're not putting $5000 under the hood in order to save $10 a week at the pump. 
think about what you're saying for a second and you'll see what I'm saying.
I dunno why you guys are trippin about when your cruizing rpm is 4000.... these are 4 bangers, they're supposed to do that.
sure it uses as much gas as a V6 would, but who's counting? Now, I'm not sure if your complaint is with paying at the pumps or if you think you'll have a problem with longevity.
either way... you mod for economy - buy a Echo or a Prius or a Insight and put solid core tires on it and get mooneyes wheel covers. if you mod for performance... you know the rest.
the only exception to this rule that I've experienced is the JSK EH3 V2.0... that thing is a true champ, power and economy in one package. it's truly a revelation. but I don't think anyone can duplicate.
