ok i seached a lot for this and couldnt find a definite answer. can i use HF injectors in an Si setup? (si manifold, ecu etc. ) in other words are HF and SI injectors interchangeable

 

yup

 

arn't hf's dpfi? (we dont get hf's in canada) but I was sure they were dual points.

 

no. they are mpfi. only the crx dx is dpfi. the std and dx hatch are dpfi also, FYI..

and that is why hf's are awesome.. they are the lightest no frills model, with no mpfi wiring required for a b16/b18 swap.

and yes.. the injectors are identical.

 

just in case you needed a 3rd yes, i have Si injectors in my 91 HF right now. They are the same.

 

awesome thanks for the help guys

 

i once heard hf injectors are only like a 185 cc flow rating? thats why i did'nt use mine when i put a B7 in the car

 

most of all honda injectors are 240cc (and thats what should be in your car)

I agree

 

I agree that they arn' the same. the numbers on the injectors aren't the same as the si ones i have. anyone else care to chime in?

 

they were fine when i put them in my hf motor. never ran rich or anything either.

 

The 88-89 CRX HF Injectors do not flow the common 240cc... tested. But the 90-91 HF injectors are the same as the Si's.
