This is a newbie question but iam really stumped on where to start my research.. I tried searches but the search always came up with advanced posts. My questions are simple:

1) what is the difference between b16 and b18?

2)if iam planning to put turbo on, which one is better?

3) what model integra comes with b16's and b18's?

Thanks

 

Technically, the b16 has the perfect geometery for a turbo.

But the b18 has more displacement, so it could be faster.

Differences. They are mostly the same, but if you have a specific question that wouold help.

 

which b16 is vtec??? and why do you say vtec sucks in your sig?? just wondering... I am def planning to put turbo on my engine, so i should go b16 series?

 

B18C(GSR) or B18A/B(LS)?

You need to be a lil' more specific about which B18 you wanna know more about.

screw turbo..that's the EZ way out!

Either B16A or B18C is good to have...both are different in flavor though.
A B16A's power band is more up on the high end side and can handle higher revs than a B18C with the proper cam setup.

While the B18C has better power all round. The B18C power band usually dies off ealier than a B16A's power band.

I've always compared B16A's and B18C's to people...

A B16 is a hard working minority - makes the most of it's time and is very efficient. ... While a B18C is a rich lazy *** white guy, who doesn't have much work to do at all - it's all done for him.

 

wow.. no mention of the almighty B17!!? i'm impressed.. hehe..

 

nah..thats my own personal engine...no one gets ta have dibs on it.
Your B17 belongs to us/me.

 

gotta question about the b17..
where do you rate it between b16a and b18C??
i know the b16 and b17 have similar HP, but what advantage would i have with the b17 other than displacement?

 

soooo turbo is the easy way out... hmmm sounds like a plan to me i like your analogy btw

 

B17's are just that...in between a B16+B18C.....
it makes more power & torque on top of the B16A, but not as much as a B18C. But, there are ways of making almost the same power as a mid-built B18C, though.

B17's come with way low compression due to the no-dome flat-top piston, yet, makes the same power as a stock 89-91 B16A engine...yet again, has a bit more torque. Now just imagine swapping out the pistons in favor for...lets say.. some B16A pistons or even some CTR pistons! now we're talkin power upgrade!

That's only real downside to the B17A...
you need to at least, change the pistons to make better power on top of a B16A engine. The rod ratio in a B17 isn't too bad either.


side:
- unique block, kind of rare
- has the potential to make more power than a BUILT b16a
- rod ratio is still good
- is a US only block, so if yer the **** type that's a worry bug about smog n' all that crap, there's no worries.
- any other B-series Vtec parts are compatible with a B17 - cams, pistons. etc.

side:
- need to upgrade the pistons (this is actually a good thing though!)
- used B17's might have high miles, may need total rebuild, new bearings etc.

All of the 94+ integras come with a b18 motor (1.8 liter) the B18B is the LS motor with no vtec, but a little more torque (so I hear). The B18C1 motor is the GSR motor More horse but a little less torque (overall faster stock vs. stock). The B18C5 is the type R motor which has the most horse power and and like 2ft/lbs of tourque more than a GSR motor.
Ls: Horsepower = 140 (at fly wheel) Torque = ?
GSR: Horsepower =170 Torque =128 (at fly wheel)
Type R: Horsepower =195 Torque =130 (at fly wheel)

Now, the b16 engine comes in Civics. It is only a 1.6 liter but you can get it both with or without vtec. I am not sure about the Civic motors so ask someone else. I also do not know much about what engines are in older year Integras and Civics so could someone please fill him in on things that I left out. And PLEASE, by all means correct anything that I said that is wrong or untrue, I don't want to spread bogus info.

P.S. I would choose the B18C1 motor just because it is bigger, and because I wouldn't want to go down in motor size; but that doesn't mean it is right for you. So do a lot of research and decide for yourself. Good luck and welcome to HT!
