I was wondering if anybody knows if you can use blue top dsm injectors in a H22A and if you need a resistor box? Will the car run right after you install them? Because I have heard they they have problems idling and starting when you use them.

 

From what I have seen in the junk yards the h23's have resistor boxes meaning that the OBD 1 prelude injectors are peak and hold. So yes you can use them if you already have a resitor box on your prelude. However I do not think you should use them without some type of injector controller. They flow 450cc compared to your 290cc prelude injectors. In other words it will run far to rich.

 

You will need a resistor box for an h22a, my buddy used one in his 99 turbo lude. I have a set a blue top injectors in really good shape with low miles f/s for cheap if you want them. Let me know.
