As long as it's a 7 wire MPFI OBD0 distributor, you're fine.

Si distirbutors have CYP and TDC sensors built into them.

 

ok so i'll make sure before i buy one. all i do is get this ecu...pluigs right in, run a wire from the output pin on the ecu for the auto feature straight to the vtec solinoid. after that when i burn a rom chip i can just select the radio button on turboedit set my vtec and i'tll work.? thanks

 

Yep.
