i have a 93 b18 motor with a 93 gsr head i want to put in my 90-91 integra...plug and play? is there a wwiring diagram i can use to do the swap???

 

well first you have to get the vtec harness into the other DA then from there on it should be plug and play. i believe all the mounts should line right up. good luck!

 

plug and play, no.

you need a pr3 pr pw0 ecu to run the vtec. you need to have that tuned for the engine.

you need to wire vtec.

search LSVTEC enjoy the results.

yeppers.. and if you just plug and play, your motor isn't gonna last long before everything ka blows

 

Keep in mind that 90-91 ran low impedence injectors with an injector resistor box.....The 93 has high impedence saturated injectors, so some type of rewiring might be necessary if your using the 91 harness....

 

or he can just use the OBD injectors. since you know they both flow 240cc's

 

That is true, but you're supposed to use the injectors that correspond with the ecu as it is what controls the them....So, if the ecu is for a motor that runs saturated injectors, then you will have to use them, or they will not work properly.....ALL 92' and above Integras ran saturated injectors, it would be futile to go out of your way to run 91 or earlier injectors, especially as it will require a different computer....Some simple wiring mods to the harness can eliminate the peak and hold to saturated problem, if you search this forum, I'm sure you'll be able to find any diagram you might need.....

 

I am confused. I thought high impedance injectors with the resistors would work in place of th elow impedance ones (or is it the other way around?0.

 

His car is OBD0, this is why I said to use a pr3/pw0 since they are OBD0 as well. He can run the head OBD0 as well as the engine, with no problems.

 

thanks guys imm pay a shop to do it
