97 ex in a 89 hf? whats it gonna take?
 

The only reason Im not doing an a6 is because my friend has two 97 ex motors in his garage. Besides the hubs/axles, what wiring problems/mount problems can I expect. All help is apprec. Thanks

if you use an 88-91 L3 tranny (HF, DX, LX, Si, or EX) you DONT need to swap axles or hubs...

Ok, well I have the hf tranny and axles ???, but is it anywhere near ideal for an ex 10 psi car?
I'm more concerned about the wiring and all that ----. Help!

well i think you should get a Si tranny, but im saying that you can still use the HF axles and hubs. axles will be fine i didnt break any in the many months that i was boosted...

OBD-0 wiring: use a 88-91 Si/HF/EX dizzy, and wire it up with the stock HF harness. then use a RPM activated switch or VAFC/Fields/whatever to activate VTEC...

Re:97 ex in a 89 hf? whats it gonna take?
 

use a vafc or fields to activate the vtec because if you use the switch, you wont get the bumped fuel and timing curve. you also need to extend the wires from the coolant temp sensor. obd0 has it on two needle plugs on the back next to the oil sender unit. on the 92+ obd1 motors, they're on the thermostat housing. its a different plug so you should cut one off from somewhere to match the male to female. on the intake manifold, you might need to extend a few wires due to different locations of sensors....but it depends on witch manifold you're gonna use. 96+ ex would be the best choice but swap the tb for one off an accord 94+. or you can drill out the holes from one off a b series and it'll bolt up with little ease. good luck
