Im getting ready to start a new project and wanted to see if anyone had some info. Ive got a 89 CRX Si and am thinking of droping a B20.

Anyone have any info or websites with info on this swap?? Please throw the info my way.

Thanks alot! !

 

It's the same as any other B series swap into an EF. You'll need an aftermarket mount kit and shift linkage, B series tranny (other than CRV) if it's hydro you'll want to get the HASport mount/conversion kit, Integra LS intake manifold and a 90-93 Integra driver's side mount bracket. The amount of wiring will depend on what OBD you go with. OBD1 would be best and will require an OBD0 to OBD1 adapter harness, 4 wire O2 sensor and a little added wiring. Just read up on general B series swap info in any 88-91 Civic or CRX. If you can't find exact specifics on a B20 although you should be able to, following an LS swap would be basically the same thing.

 

Go to http://www.b20vtec.com

They have alot of info!

 

The only REAL difference between this swap and any other B-series swap is getting the parts you need. Unlike other B-series swaps, there is no swap package you can buy. You must separately buy the engine, transmission, ECU, intake manifold assembly, and mount brackets.
