Has anyone seen it done?

 

im not sure of this..
but theres one crv here did a
b20/V with a typeR head and a turbo..

from what i know, b20 is a bore out
b18 block, not a high revving engine,
coz of the thinner sleeves,
and im not sure if theres gonna be
an issue with the tranny, if its rtawd..

 

good luck finding a CRV with 5 speed, they aren't exactly plentiful. Theres always conversion.

 

Conversions are mad expensive. It can be done, but it won't be worth the money spent.

I can't see why a B18c5 engine wouldn't work. I've got a C1 and B20block and they're loving each other, especially when VTEC pops. The main problem you'll have is tuning it. Autobox, you won't be able to chip the ECU - so you'll need a piggyback. Manual = love!

 

There are manuals available, so I am not worried about that. My main concern would be mount positions and possible hood clearance (haha... JDM tilt, yo). May have to beef up the tranny,etc.


Anyway, back to my original question, please.

 

you should be able to tune it, you arent talking about a newer crv are you? that would be kinda lame i think.

 

The B18C5 will fit right in, only real problem being the transmission. The B20 that comes in the CRV is higher displacement, longer-stroked B-series motor that can't handle the higher RPM's of a B-series Vtec head for long without reinforcement. IIRC there is a way to mate an automatic tranny to a formerly-manual drive motor. Anything's possible with enough time and money.

 

Not looking to put this in an auto. I am hoping to find someone who had done it or knows of someone who has. This uncharted territory could be expensive and time consuming and I rather have a map

 

It's got 12 inches of hood clearance, mounts will bolt right up, and switching to obd-1 and running a chipped p28 you could tune it just fine.

 

California would not approve of my Obd2-OBD1 conversion. I would actually like to get it BAR-ed so as to be legal. They want the same emission equipment as the year of the engine.

 

You could use a type-r ecu but it would have to be of the same year to work.

 

"Light Duty Truck" and "Passenger Car" engines can be problematic for the BAR.

For example, it is illegal to use the B20 from the CRV in a passenger car, regardless of year of either. You simply can't use a truck engine in a car and pass smog.

I have never bothered to look if the same restriction applies for using a passenger car engine in a light duty truck, but it's something to check up on.

 

OP, I'm not flaming, but what is your intent? Are you doing this just to be different, or do you just want more power? You have some constraints on your options regarding legality since you must bow to CARB.

 

rather have a c5 in a civic.

 

i waited 2mos. to find a white stick CRV....
ive seen couple its just not my type,
im in the process of doin a B20/V conversion;
im just gathering few things and waiting for
the weather to rise up a bit, its still cold
in the tri state..
anyway there are a few write ups regarding
this conversion you should be able to search it!!

good luck on your swap/conversion project!

 

the should be no problem whatsoever. its a b series motor in the crv and you are replacing it with another b series motor. there should be no clearance issues whatsoever. if you decide to do the head swap you shouldnt even need rto take out the motor unless you are doing internals too. you could even do a type r tranny if you wanted but you would have alot of dead weight from the rest of the awd system. if you are going through all the trouble i would put in an h22 if you want good tourqe and hp gains. i found my manual crv i one day. saw it called up the dealer and went and picked it up later that day. your best bet is to just do a turbo or just a crap load of bolt ons to pick up a few horse. it would be the same as doing an ls teg. so in regards to all this light duty truck and passenger car crap, what makes the ls and b20 so different besides displacement? nothing!

 

Going to be very exspensive.

 

Besides displacement, what the law considers them to be is what makes them different, and that matters much much more than the reality of it being just a stroked B18B.

Light duty trucks are not held to the same emissions requirements as passenger cars. I would assume that is the primary reason truck engines are not legal to use in cars.

As I posted, if the OP needs to pass the BAR, he needs to verify that it is legal to use a passenger car engine in a light duty truck. That is what the law considers the CRV, and all other logic applied is meaningless.

The law doesn't care about logic, only that you follow what is written.

I have a 1979 Triumph Spitfire that tested 5 PPM HC on the smog sniffer test, and is good for 50+ mpg freeway. My Integra GSR tested at 49 PPM HC, and only manages 27 mpg or so freeway. My Integra is smog legal (its stock), the Spitfire fails the visual due to a non-smog legal carburetor, header, distributor, coil, intake manifold, etc... 1/10 the pollution, almost twice the mileage, but not legal...

 

Lots of misinformation in this thread in regards to the swap (not in regards to California laws).

I know you're probably not going to do the swap, but if you were, it's not as difficult as people may lead you to believe. The engine bolts up the same, but you need to reuse your stock CRV transmission because the CRV uses cable shift linkage as opposed to the ITR's rod linkage. There's no problems with engine clearance because the B20B and the B18C5 have the same deck height, but the CRV engine is a little bit taller because the intake manifold has extremely long runners that stick straight up. Throw in a VTEC ECU (don't forget that OBDIIB P73 has immobilizer), wire up VTEC solenoid, knock sensor, etc., as you would with any other Honda B-Series swap, and you're all set. Stock CRV exhaust manifold bolts up to the B18C5 engine without problems. No need to worry about the AWD because the AWD system is hydromechanical, not computer controlled.

 

Do it!!! b18c5 all the way night and day compared to a stock b20.
