If I use the pm6 or pg7 ecu with the swap, which intake manifold can I use?

Also if I get the odb-0 to obd-1 harness is there still anymore wiring? and which intake manifold can I run?

 

u can use any 88-91 Si intake manifold. u can use any Z6 intake manifold ( if u do use the stock Z6 TB MAP sensor)
with a OBD1 converison harness u still need to repin the distribuitor, the injectors and vtec, oil press, H2O temp

 

what distributor are u using
