Just swapped an obd-0 b18a1 into a 1991 CRX HF using both the HF engine and chassis harness.

The Engine runs, but like ****!

Are there any plugs/sensors that need to be changed/added/deleted when doing this swap?

TIA

 

The dissy is you problem. The hf and si harness are diffrent. I did the same thing. I was swaping in a single cam. I just used the hf dissy and intake but you cant do that. you need to swap the under dash to si. or repin the dohc dissy to the hf wiring if you can idk. good luck those hfs are a MF

 

Were already running an obd-0 b-series dizzy.

So your saying that the plugs on the HF harness are different than the plugs on the b-series dizzy?

DO NOT LISTEN TO THAT POST!!!

The HF and Si are the same as far as wiring.

 

ask rywire thats where i got my info.

 

So the HF harness should plug right into the obd-0 LS motor without any modifications?

No extra plugs needed?

We already have the motor running, but it doesn't run right. I'm just trying to make sure that I don't need to add any plugs..

 

Couldn't tell you for sure, but Ryan Basseri, the owner of Rywire can.

the trick with my swap was the obd-0 to obd-1 try that it should run better because the ls motors are obd-1 any ways i think

 

Make sure your Map sensor plug and you TPS plug aren't switched they are the same.

 

^^^ also iac and iat are the same and easily mixed up. if it is an obd1 enging then u may need to advance the distributor alot and by that i mean past what the distributor notch allows. at least that is the case when i ran my d16z6 with a obd0 distributor. and what ecu are using? i hope not the hf one.... that would be a problem

 

any error codes
