Why doesn't anyone do this swap for this car? it seems like this motor would be the ultimate motor for going all motor on a CRX. All you need to do is get some mounts, the cable tranny which usually comes with a complete swap, and the OBD2 wiring...

i have yet to see 1 b18c5 in a crx...everyone does b16's adn sometimes, MAYBE a b18c1...can anyone show me a b18c5 rex?

I was planning on going all motor on one of these in a rex, which some Comptech headers, 2.5'' piping and an HKS muffler, AEM intake, throttle body, intake manifold, high flow injectors, dyno Tuned V-AFC, cam pullys, unorthodox under drive pullys, a stage 1 camshaft set, valve springs, and retainers Tein RA coilovers, comptech sways, stablizers, short shifter, master urathan bushing kit and work rims with 205/45/16 toyo proxies...how does this set up sound? i'm thinking really low 14 or high 12...is this off? infact, with this set up..i think i'm under estimating the car.


thanks for the time guys

My friend's car does 13.0 with a basically stock B18C5 that is choked with a 2" exhaust. This is an 89 hatch, btw. The setup you're talking about could hit mid 12's with traction quite easily.

EDIT: Get slicks.

 

Well first off there was post about this, I think it was called "B18c5 civics/rexs lets see um" or somthing like that try the search with somthing close to that and you should find it.

On top of that, when you buy a complete b18c5 swap it doesnt come with a cable tranny, all b-series from 92+ come with hydro's(well most all esp. the Type R)

With the hydro, you have to convert from cable to hydro clutch and you have to have a different rear tranny mount from what I know. My biggest concern is switching to obd1.....which IMO is stupid since i know alot about on board diagnostic systems its kinda dumb to do this, and you ask for alot of troubles, but on the other hand alot of guys have been able to make it work, and its a great swap.

Id rather just do a b16a, rebuilt by yourself/ Ls/vtec with b16 tranny or 2nd gen gsr tranny, made to be obdo, and everything you can get from hasports.

Personally I would buy custom axles, the linkage, mounts, and even the wiring subharness to make things easier even though I have an si.

There is one here in Greece with the b18c series motor (and some other stuff) which is faster than a S2k .
but I think that it's not as simple as it seems to...
....to fit that motor in a '89-'91 CRX...

 

can't u slap on a YS1 cable tranny to the R motor so you won't have to change the rear mounting bracket?

 

yes, a great find esp with a quaife installed...i have a jdm b18c just put into my 91 ex and am getting past the teething (also have todas, pistones, etc.)

 

short gears are good

 

Hasport has a mount kit for putting the B series swaps with Hydro trannies into the EFs. It includes a mechanical setup to convert the hyrdo operated tranny for use with your EF cable clutch.

 

Sounds Gravy....but hows a b16b? that'd be pimp...but 1.8 lol...i dunno...we'll see...my friend has a b18c1 in a rex and it dropped in fine with mounts and thats it...thats all he cahnged.

 

Hmm 16b is good for a rex it would scream.

So will the type r.

As for the OBD you have to go OBD1 If you want to say preobd u can but I suggest with all the **** u getting you will need Honda data to top it off.

I have drove a 16b its nice and fast but the type r is 1l8 block more torque low end the 16b u can rev that bitch like I do all the time make sure u run open headers to scare pedestrians/bums/crackheads when vtec kicks makes them jump off the road when they are walking on the road

also get the hasport kit or run a ys1 gsr or jdm xsi tranny sell the jdm lsd tranny and get the ys1 rebuilt with lsd etc.. its a good swap for a rex or civic

 

Locash sells an OBD0 to OBD2 adapter so you can run the CTR ECU with a B16B swap.

 

ok, so lets get this strait...I need to get a y1 tranny, wiring harness for obd2(what other obd2 parts do i need?) and some mounts...and then i can go get it installed propperly and go get it barred by a reffery right?

The JDM B18C5 and B16B are not really OBDII motors. Being JDM, they are actually non-OBD motors (and not like 1988-1991 USDM motors, which actually use an earlier version of OBDI). In other words, the only things that is really 'OBDII' about these motors and ECUs are the ECU plugs and distributer plug. As far as the rest of the wiring and the sensors go, the setup used in the JDM B18C5 and B16B is quite similar to 1992-1995 USDM cars. In other words, it is basically the same as a 1988-1991 car. But the ECU is not compatible with a 1988-1991 distributer (and vice versa, just like 1992-1995 OBDI). And it uses a four wire oxygen sensor (again, just like 1992-1995 OBDI). There are, however, a couple of important differences, both of which actually make life easier. First, there is no terminal for an EVAP purge valve. So you don't have to worry about this (although wiring the purge valve is not a big deal, as the wiring already exists in your car). More importantly, the JDM B18C5 (and probably B16B) does not have a VTEC pressure switch. This means one less wire you have to worry about adding.

 

On a recent trip to Maryland international raceway for the NIRA Import vs Domestic race this past November a friend of mine brought his freshly swapped 90 crx. He had CAI, JDM header, Apex N1 and ran 13.1 on street tires. He had been driving the car for 4 days. Im sure he will improve his times with more seat time.

 

probably cause you can do an ls/vtec without having to change the clutch and make about the same power as an itr and not spend $5000

sounds like a good reason to me

A couple of things. First of all, you don't have to pay $5000 for the whole swap. I only paid about $3000 for the complete motor and used my B16A transmission and mount kit. Secondly, the B18C5 has the advantage over the LS-VTEC of not having reliability depending on how well the engine was built or the quality of the parts used. And remember that a properly built LS-VTEC is probably not going to be any cheaper than a B18C5.

 

well here is one, It says with GsR but it was a c5 he ran I think it says 12.08@113mph all motor.

yea...cept you can make one legal...the c5.

AMEN

 

my friend has a B18C5 JRSC 10 psi CRX....photoshoot will come next week..be on the lookout...cleanest rex I've ever seen
