I am doing a swap in my 84 CRX and was told to go with the B16A I went to Osaka and they have the B16A1 (SiR-1)

seen here

What are the differences and what will be any install differences if any??? all the HOw-To's I have talk about the B16A

 

B16A1 (although I don't believe there really is an A1, thats just what people call the first gen B16) is just the 1st generation B16. It was OBD-0. I think the only real difference between that an a B16A2 is that that is OBD-I and has like 10 more hp.

However for you it doesn't bolt right up into the '84 CRX. You will need to buy custom mounts (they might make them for that swap, I'm not sure) and a custom linkage to at least get it in the car. Then wiring. Is your '84 Carb or Fuel Injected. If it is Carb then that already makes it more trouble than its worth for the swap I think. There are other Carbed Honda engines that fit into your car. If it is Fuel Injection than you can do the B16A easier, also if you want a cheaper alternative I believe the D16A1 bolts right into the 1st gen CRX.

 

installing the b16 will have 2 major differences mounts and wiring, aside from that u have to deal with throttle cable and clutch cable lengths and of course the shift linkages. it sounds intimidating but www.hasport.com sell coversion parts that will help a lot. they also have online instructions on how to tackle the swap. i'm 98% done with my swap now.

 

Personally I wouldn't buy from Osaka. I heard way too many bad stories about them. If you do a search you might find a forum about them. Becareful buying from them! But since you live close enough to go check out the motors, maybe you're ok. Just have them do a compression and leak down test for ya. Good luck w/ the new motor

 

we can help you alot more if you let us know your exact model/trim.

 

Good luck, that swap is a bitch-and-a-half.

There was no such thing as a fuel injected 84 CRX, at least in North America. This means you have to fully convert to 85 Si spec, swapping a lot of crap (fuel lines, pump, gas tank, wiring harness, ECU, etc.).

Then you have to go to HASport and buy lots of custom parts to wedge the B series into the 3G platform (mounts, shift linkage, axles, wiring conversion harness, etc).

If you get all this done, your bank acount will be a few thousand dollars lighter and you will have damn fast car, as the 84 CRX is the lightest body that B-series swap kits are availible for.

Much more info, including my longer posts on this subject, are in the motor swap questions sticky at the top of the page. Any info regarding carburated 84-87 Civics and CRXs will apply to your car.

Note: Carburated cars have no real OBD system. The 85-87 FI system is a primative OBD-0 which I personally call pre-OBD, and the 88-91 cars use a true OBD-0 system though it was not know as such until the implimentation of the OBD-1 requirements in 1991 for 1992 model year cars.

 

1984 Honda CRX POS


I am not sure EXACTLY waht trim it is. its the old carb POS.

 

Everyone says that converting from Carb to FI is a pain, but if the car is striped down to fram it shouldnt be that hard to run wires.

 

B16a1 is cable tranny, b16a2 is hydrolic tranny... get b16a1.

 

Thanks
