on a side note, I have a gen one manifold for sale.

also if this is going into a rex, you are gonna want to keep it all obd-0

the head the block doesnt matter like Kai stated.....the year of the motor doesnt mean dick, as long as you have the proper obd and wiring then it will work just finel.

oh and you will also need obd0 injectors to work with that obd0 ecu. I also have those for sale.
