its the same as any other b series swap into a CRX.
you need
mounts, hasport, place racing, innovative... etc.
modify your
stock engine harness. if your CRX is a DX, HF (88-89) or Standard you will need to add MPFI, lengthen the TPS sensor as well as map sensor, I think. Don't listen to competeiveaudio... (no offense dude) because you not use the 90-93 integra harness. for more than one reason. the harness is not plug-n-play with a CRX, not only that but the 90-91's were obd0, 92-93 were obd1.
you need to locate an
LS intake manifold
get
obd0 injectors
get
obd0 pr4 ecu
get
obd0 or obd1 (they're the same, no difference in the big green plugs)
alternator
obd0 ls
distributor
You will also want a
90-93 integra transmission, or if you're lucky and can find a cable b16 transmission then get it. but make sure to find out what year it is. if you don't, then you might have some trouble getting the right clutch. 88-91 are small spline input shafts where as 92-93 are large spline, they use the same clutch disc as hydraulic b series transmissions
90-93 integra throttle cable and clutch cable
you need the
rear engine/transmission mount bracket from 90-93 integra, this is crucial, no 94+ wont work nor will any other b series or d series.
If you've got a standard or HF CRX you will need to get either
DX or Si steering knuckles AKA hubs, otherwise you'll never get the axles required for the swap to work...
lastly, you need
90-93 non ABS axles as well as the intermediate shaft. passenger axle depends on what year transmission you get.
I've bolded everything that you'll need... this list is just off the top of my head, im sure there is stuff missing, but for the most part im sure its pretty accurate.
