which manifold mpfi?

right now i have the 1.5 dpfi, i was wondering which manifold i need to use if i go MPFI. I plan on going to the LS b18a/b, so will the crx si mpfi swap work with the b series motor?

yes. almost all honda MPFI wiring is the same, if its OBD0. OBD1 doesnt have the need for the resistor box, and also has differnt plugs on the injectors. If you're swapping in a 90-91 B18A1, which is obd0, it will plug right in. If you want to use an OBD1 B18A1/B1 you'll have to convert it to OBD1 by removing the injector box and using OBD1 injectors.

If you are saying you first want to convert your 1.5 to MPFI using a MPFI manifold you will need the 88-91 Civic or CRX Si Manifold. However that manifold will not work on a B-series, they don't work with D-series engines. But if you plan to swap in a B-series later the wiring is all the same as long as it is OBD-0.

hey..thanks for the info, Yeah i wanted to know if the d manifold would work with the b engine. well then i might as well wait til i get my b18.

thanks guys
jus

oops misread, just thought he wanted to know if the wiring was the same :eek:
