i have a 93 ls motor that i am putting in my 91 crx si and i was wondering can i use a 90 integra dizzy and 90-91 ecu with my stock si harness and have everything work fine? what else will i have to change if i use the stock si harness?also 90-91 ls b18a have 130hp and 92-93 have 140 is the hp difference b/c of the cam or the ecu or alittle of both? if no one knows i will ask the integra forum i just figured i'd ask while i was on topic.

 

u can't use the 90 teg dizzy (obd0) on a 93 teg motor because its an (Obd1). BUt obd0 to obd0 is koo.

what? If he's using the si harness then it should be 0bd0 which is the same obd as the ecu he is going to run. I have no clue what you're talking about.

 

i would say http://www.rywire.com BUT you don't need us for this.

The fan switch is different on the OBD1 block, but with that engine you can swap the Si Style Fan switch onto that block so no wiring is required. The fan switch on the thermostat housing can be left alone, you just don't use it but you don't need to remove it either.

You can use your OBD0 injectors with no changes.
OBD1 injectors require 12 volts.

OBD0 (non-OBD) ECU's use OBD0 Distributors, OBD1 ECU's require OBD1 or 2 Distributors. (OBD Compliant)
