What would be a better swap for my crx?? Pros and cons? Both are awesome motors. Just curious

1fasthb

b18c5 pros- more power cons- expensive
b16b less money but less power

i recomend b18c5

jaydmcrx

yah i was gonna go with that too

1fasthb

i sell you mine

temp

b18c5-pros-more displacement, higher compression
b18c5-cons- poor R/S

b16b-pros-better R/S and i cant think of much more
b16b-cons- less displacement, lower compression

jaydmcrx

Yah but with the c5 you make more power. And i doubt the rod to stroke ratio is that big of a deal with the c5. The main reason i want it is for endurance racing and day in and day our driving hard. As far as im concerned that motor is made for such things

cjb92

I'd go B16B. Once you get tired of it being 1.6 litres get a gsr crank and rods and blamo you just stroked it out and have a high compression(somewhere around 12:1) bad *** motor..... With all the goodness of the ctr motor like the crank pulley, cams, head, intake manifold, and aluminum lower front driver mount....

temp

uhhhhh 1.5x compared to 1.77, uhhh yes that is a VERY poor R/S in compairson to the CTR R/S

jaydmcrx

Yah but still that motor can take anything you wanna throw at it. Its very well balanced and can take an *** kicking in many races. So now its not as easy of a decision now damnit i hate asking questions oh well here goes the decision making process

temp

both are well balanced and can take anything you can throw at it, but using geometry the b16b in theory should last longer while taking more abuse

what you be revving the engines to? Isent the R a grand more?, why not go b18c and build it, or you just want to throw it in and leave it?

poison

C5 by far.

you will regret getting the B16.

Man up and go for the big one!!

Thanks for the laughs!!!

Funniest thing I've read all day!



Really man that's weaksauce. the B18C5 doesn't have a "poor" R/S ratio at all, it's just that the B16B has an awesome one.

I've beat then **** out of my B18C5 for 3 years now and it has NEVER given me one ounce of engine trouble - ever.

20+ passes at the strip, numerous auto-Xs, out of town road trips, and daily driving that sees 8500rpm daily - best engine I've ever owned.

50K miles and it doesn't smoke or anything.

If you plan on leaving the engine mostly stock, I'd say B18C5 all the way.

I think if you're going to tear down any Honda engine and add in human error and potentially ruin the build, try ruining a B18C1 instead of tearing down a B16B.

The B16B is great for one thing - road racing. It still has no torque so IMO it would suck for daily driving when compared to the B18C5.

temp

puhhhhlease, it DOES have a poor R/S, did i say that the engine would not be reliable? no, it is designed that way from the factory so it will withstand what you throw at it, but engine geometry and the R/S theory would mean the b16b would last longer IN THEORY......both engines are RELIABLE engines and i never said they werent, but you cannot deny the fact that having a 1.5x R/S is BETTER then having a 1.77 R/S for overall longevity......

I really doubt thats an issue, if that were the case honda wouldn't have produced this "performance" engine...

NO, it does not have "poor" R/S. Maybe "poor" is not a specific given definition, and just an opinion.

Because if it was POOR, in terms of speaking by a real "poor" RS, such has as an old school V8, it wouldn't last long at all.

Regarding the C5, it's not as "good" as the CTR's R/S, HOWEVER, it's in no way "poor".

`nuff said.

Hey genius, what type of engine do you actually own and have experience with?

temp

i OWN a b18a, building a b16a and have experience with the following honda engines (since i do not want to list all engines i have experience with)

b16a
b18c5
b18c1
b20b/z
c32's
f20c
h22a
f22's

does that satisfy your likings GENIOUS :roll eyes:

you are right, i was talking poor in relative terms, it just didnt come out how it sounded in my head, the way you worded it gets my point across much better....neither are poor engines and both will last forever, the b16b will just put less stress on its engine internals during that time

it isn't really, like i said, they will both last forever just the b16b will be putting less stress on its engine components

yes but no....b16b can handle a little higher revs. When it all comes down to it power difference is so minute that it should not even be an issue. Its a tough decision, your basically talking apples to apples. Both are perfect for All motor setups and handle very low boost stock w/o some major internal modification. Compression is the almost same. tough decision. Tom did make a very good point: ITR motor would be best if you have no plans for modifications past the swap. He also brought up the torque issue, which cant be contested, CTR motors have **** torque, remember its a civic motor. Are you completely against a LS vtec or GSR motor???

honda's dont have torque.....

...but I'd rather have 130ft-lbs. or torque to the WHEELS with my B18C5 than some 102 torque at the wheels like some B16B would.

I don't give a **** what engines you've "had experience with" quite frankly. Until you've driven one every days for years, you cannot really tell me that a B18C5 "has stress on its internals" or whatever line of BS you're trying to spoon feed us.

The B16B is just a sillt idea IMO for the price.

"Yeah but put a 1.8L crank in it and it's a Type R engine"

Yeah well what about labor? Parts? Machine work? Are you going to trust a foreign crank in a block that you're revving to 8500rpm on a daily basis? Parts and labor to stroke the B16B would exceed the price of an already-built B18C5.

I have driven a real Civic Type R, RHD and all. The B16B is a gutless rev master that pulls worse than a B18C1.

Have you driven both engines before?
