Ok im starting a new project on my 98 coupe.

my question is which jdm type r motor swap would be best, itr 96-97 spec b18c? 98+ spec itr b18c? or ctr b16b?

i heard the cams in the ctr are better?
also that honda put ctr cams in the 98+ spec b18c?

i knw tht the b18c has 11.0:1 compression nd the b16b has 10.4:1 compression but people tell me tht thy went with the b16b swap nd thier car was a "beast"

Only time its really worth bothering with a B16B is if you are racing in some kind of 1.6L class. '98 spec gives you an alright 4-1 header (which is easy to change on the '96 anyway), and '98 has lower diff. Basically need to decide if the extra money is worth those two things.

Why does it matter which has the better cams or higher compression? Look at the power and displacement.

B16b: 1.6 ltr 185 hp 116 Trq (10.8 compression)
B18C: 1.8 ltr 200 hp 134 Trq (11.1 compression)

It's pretty obvious which one is the best option and the best platform to start with. I'd take the JDM b18c-r over the b16b any day.

the way i see it i think its worth the extra cash

EJ8_R

true. but idk why peopl keep saying tht the b16b is better whn the 200 hp ovr 185hp to strt says it all

fv8s

easier to change? lol

and a lower diff? i think you mean different final drive/ gear ratio.

Just so you know, CTR cams are the SAME cams used in the 00-01 ITR engines

People get all hot and horny over the B16B because it's rare, but meh....the B18C makes "more" power!!!! I would take a B18C any day of the week over the smaller torqueless 1.6L CTR engine

If you have money go with the 98+ model ITR

You wanna fight? jk.. ^^

When I first bought my hatch it came with a b16b..it was a fun lil engine but it did not compare to the b18cR that I had before it got built. I would say get the ITR swap..Any years is good..

EJ8_R

then a 2000 b18c is the motor im going to go with.

I meant the '96 header is easy to swap for another one anyway. And yeah FD is what I should have said

96-97/ 98-00 b18cr motor it doesn't matter as long you get the type r tranny with it. That matter. Remember there are two different tranny with final drive 4.7fd/4.9fd. I haven't seen any b16b motor out where I live so like you guys said it's a rare swap than a itr swap but from my opinion when swapping in a b16b why not add a grand and get a itr swap when it has +15hp + more TQ + bigger liter. Have a 96 itr swap myself loving it.

EJ8_R

the FD on the 98+ spec is 4.7 nd i believe the 96 spec is 4.4. correct me if im wrong.

Deetz

This isn't correct.....

the jdm 1996 and 1997 had a FD of 4.4 just like all of the USDM Type R transmissions

It's the 98+ ITR tranny that came with a 4.785 final drive for very spirited acceleration

fv8s

4.785 fd = sex

canadaek

anybody know what the final drive is on the CTR ?

EJ8_R

nd with lsd

EJ8_R

so im gonna go pick up this motor (00' jdm b18c type r) at a warehourse in new jersey called JDM Engine Depot, idk if any of you heard of it? but their price isnt bad. they are asking $3,699 for the swap with lsd tranny. but i see it doesnt come with axles, shift linkage, nd motor mounts.

since this is a warehouse nd have alot of motors, they should give me paper wrk that state it came out of a 2000 right?

nd the year of the motor is on the head if im correct?

93egSLEEPER

The B16 is honestly on its way out. LS platforms are more sought after now, at least in my area. I would get the ITR swap (JDM B18C-R or B18C5) before a B16B anyday.

jerryegk24

You guys are right 4.4/4.7 lol...my bad. Yes the year of the motor it should be on the head cylinder right above the header. Should have something like 9/6 = 96 and so on.

mr_masel

no replacement for displacement

I'd go for the b18c spec R 2000 spec

oh and correct me if I'm wrong- its the late 2000 model that comes with the b16b cams. the 98 spec comes with b18c cams. both in 4-1 stainless steel headers

difference in tranny gear ratios as well but I'm sure all knows about it

I prefer 4:4 though

good for highways

bought a 96 spec instead of 98 cause i want the tranny better

also am rolling on 195/55/15 ad07s, so better suited for 4.4 tranny

engine number starts with 190*****

Deetz

The opinion of of which tranny is better, is in the eyes of the beholder. I got a 98 spec tranny because of the 4.7 FD. I then refreshed it with new syncro's, new 3rd gear, and a new 5th gear from an LS tranny....so there you go, a tranny for the best of both worlds

B18C5-EH2

Guess what?

The ITR tranny with the 4.400FD and 4.785FD have THE EXACT SAME RPM IN 4TH AND 5TH GEAR!!!

Impossible?

What you probably don't know is that the 4.78 tranny has a TALLER 4th and 5th gear to make the overall ratio (once multiplied by the FD) nearly exactly the same as the 4.400FD tranny!!!

Here's 5th gear for comparison:

4.78FD x .787 5th gear = 3.76

4.400FD x .848 5th gear = 3.73

You will absolutely NOT feel an overall difference of just .03 in gear ratio in 5th gear.
