Few questions on DPFI to MPFI

Since my car is an '89, will I need an '89 Si Distributor / '89 Si ECU when I convert it?

Thanx.

well anything 88-91 and you will need a resistor box

Yeah I know, just wanted to make sure that the computer and distributor were compatible between models.

any 88-91 MPFI (EX/Si/HF) distributor will work with any OBD0 MPFI ECU (PM6,PG7,PM5,PR4).

Wait...the PM5 is the computer in my LX, isn't it? That'll work with MPFI?

oops, i meant pm8, CRX HF ECU. sorry.

Ok, gotcha. Thanks.
