I must say this has been a pretty easy swap with all the good writeups. Props to droppedcrxsi and his great howto (http://www.norcalcrx.org/droppedcrxsi/) and to these other great links/threads:

I do have a few questions:

94 B18C1 --> 91 CRX Si

1.) What is this CRX sensor? (Back of the intake manifold)




2.) What is this GSR sensor? (under intake manifold, sorta by knock)




3.) I kept the GSR intake mani, but my fuel filter hits the intake tubing. I think I'll just relocate a few inches lower.




4.) (I can search this one... ) what about the mechanical vs electrical VSS?



Everything else is ready. I'm sticking with obd1 on the injectors so I repinned the injector clips, eliminated the injector resistor box by repinning the OBD1 block-off. Also distributor repinned, fan switch relocated, backup switch soldered, VTEC subharness is next to-do. Any other wires need to be extended? IAT, TPS, EACV? no? (I'll find out with trial and error)


Thanks to all who respond

1. Majestic Honda just lists it as a valve assembly, looks like it has something to do with vacuum assembly:



2. Not sure what that is, but looks like its related to vacuum again.

4. If you use mechanical, you can keep your stock instrument panel in the dash. If you go electronic, you'd have to convert over to obd1 type clusters (gsr, civic si...)

 

As I suspected on all. Thanks for the reply.

 

2. IAB solenoid

4. Use the mechanical one.

 

Isn't #1 the FICV?

 

#2 is definetly IAB (secondaries) hook it up to the vtec solenoid, kinda neat and cool, when hooked to vtec sol. wire (spliced in) secondaries will open upon vtec
on the 2 wire plug, 1 will go to a ground on the engine and the other to vtec sol. wire.

As far as the electronic speedo toss it, use a 90+ DA speedo unit mechanical if that doesn't work I beleve even a D series 88-91 Civic speedo unit may work. Both are junkyard items.

Edited- Yep #2 is the IAB secondary butterflies. Thanks yo. (I had the EVAP purge and IAB mixed up in my head - do I need the EVAP hooked up?)

Found this nice thread: https://honda-tech.com/zerothread?id=1077854

On the Speedo sensor, I do have the oem 91 CRX Si mechanical, but it seems affixed to the tranny, am I wrong here? EDIT - I guess I lock on it with a vice and tug. Fun.

Thanks for the help yo
