I had an idea of running prelude injectors on my crx with turbo kit. I'm getting an FMU so I want to upgrade the injectors a little bit but I'm still OBDO. Does the 3rd gen (88-91) preludes run OBDO?

 

Here's something to referrence Injector Flow Rates:

1988-91 Civic si/crx si Peak and hold 240cc
1992-95 Civic si/ex Saturated 240cc
1996-00 Civic Saturated 240cc
1990-91 Integra Peak and hold 240cc
1992-00 Integra ls/gsr/type R Saturated 240cc
1992-96 Prelude non-vtec Peak and hold 240cc
1992-96 Prelude VTEC Peak and hold 345cc
1997-up Prelude VTEC Saturated 290cc
1991-up Sentra se-r/200sx se-r Saturated 265cc
1991-up MR2 Turbo Peak and hold 440cc
1988-91 Supra Turbo Peak and hold 550cc
1993-up Supra non -Turbo Saturated 315cc
1993-up Supra Twin Turbo Peak and hold 550cc
2000-up Celica GT-S Saturated 310cc
1990-up Miata 1.6 liter Saturated 215cc
1993-up Miata 1.8 liter Saturated 240cc
1993-up RX-7 Twin Turbo Saturated 550cc/850cc
1990-96 300zx Twin Turbo Saturated 370cc
1991-up 3000GT VR-4 Peak and hold 350cc
1989-up Eclipse Turbo Peak and hold 450cc

Years Pre-92 (as in xx-91) injectors are pretty much all OBD0 and are called peak and hold style injectors that use a injector resistor box for their primary control unit. OBDI are 92-96, and OBDII are 96 on (someone might correct me on the years, but they are pretty close) and are called saturated style injectors that are internally resisted and are controled by the ECU. Anyway, any OBD-0 injectors will work for your application.

BAM!!! What do you think about THAT?!

those 3gen lude injectors are probly 240cc same as all the other B's. although there was so few things to do to them it was never an issue and no one ever talked about it O_o. so im not sure.
and they should be OBD0, if you see a little metal box on the driver side fender they are P&H OBD0 injectors.

i have some 90-91 teg injectors if you want them. they need to be cleaned though. came on a motor i was putting in, but i put the owners original on and kept them.
