it's time for a swap for my hatchie, i'm between a gsr or b16b.
my reasoning behind the ctr is the ability to achieve 1.8l by the stroke while others still think it's a 1.6, plus it's a bit more rare.
the gs-r is a great motor, i just think it's a little too common on the road.
can anyone post their experiences/opinions on the two?

 

Huh? The b16b is 1.6 liters. Basicly its just a destroked b18c5.

 

thats what i mean, take it to 1.8 by the crank, therefore having a 1.8 badged as a 1.6.

btw: what is ops/sds?

 

i'd get a b16b

 

If you plan on building either motor, which I'm assuming because you're talking about throwing out the 1.6L crank, I would go with the B18C1. It's gonna be cheaper than the B16B and will leave you more cash to mod it.

 

The B16 has a shorter deck height. Therefore, you cant use the B18C crank or rods in it. I would get the GSR motor since its going to be much cheaper, and with the money you save, buy some JUN cams and high compression pistons

 

i have to disagree w/ you on the b16b crank issue, guy i know did the same mod and it ran-in fact it ran 12.1 on the motor. i'm confident this can be done.

 

...uhh if you're referring to a B16B's deck height, you're wrong. B16B uses a P72/B18C block casing which means equal deck height.

that's my understanding.

i just got word on a '96 gs-r locally for $2000., everything but axles,ecu,harness.
should i jump?

 

I would..that's a pretty good damn price. Make sure it's legit though. You can reuse your civic harness if you plan on upgrading to a Skunk2 manifold along with reprograming your ecu. Axles you can find somewhere else...

 

Get whatever you want, but stroking a 1.6 to a 1.8 would be going from a near perfect R/S ratio to something a bit worse. The B16 will be grrrreat to rev. What about boring out a B16 to 1.8 instead?

 

So your saying a B16B(CTR) uses a different block than a B16A? Why would Honda use a B18C block, which has a longer stroke, therefore longer sleeves, with a 1.6 crank? That doesnt make any sense. Ive seen a few B16Bs and they are just B16s with higher compression, cams etc. B16B is to a B16a as a B18C5 is to a B18C1. Just my take on it.

 

the R motors are wastes of money
if you wanna drop over 5000$ on a swap, buy a second gen b16 and build it. it will spank any b16b or b18c5.

I am with the earlier post, having the B16B you are at a revving advantage over
the B18C1. Undersquare engines make less TQ than square or over square engines. Most Hondas are undersquare, the K20C is perfectly square at 86 x 86 for example and makes GOOD TORQUE. If torque is what you want, build a B16B sleeve it and put balanced, forged 84.5mm pistons and stock sized forged rods in it
and spin till your heart is content! The rod to stroke ratio is superior in the B16B
over the B18C1 < this is the motor I have.

My $.02

 

You could bore a b16 to 84.5, and have a 1.8l, or you could bore a B18C to 84.5mm and have a 2.0l. Yes, the 1.6 has a slightly better r/s ratio, but its not like a B18C wont rev to 9k. It would cost the same to bore either, so why not build a bored 1.8 and have way more torque/hp than a bored 1.6?

 

The deck height on that b16b is wrong.
Its the same as a B18C.

 

By B18C, you mean the JDM ITR block ? Would that be the same deck height as the B18C1 anyways ? (My personal curiousity)

 

B18C1,B18C5, B18C6, B18C7,B18C4, B18C , they all say B18C hence they are all the same block.

Doesnt matter if its US ITR, JDM ITR, JDM GSR, Euro ITR, WHATEVER.
Same thing.
