I have a OBD1 h22a swapped into my eh2. I purchased the car with the engine already swapped and today a friend noticed that there isn't a resistor box at all. The car has been running like this for at least 3 years.

What can happen if one isn't installed? Since I've been running it like this for so long can I see problems by installing one now?

I've searched all through the archives and found lots of info but none told what's the outcome of not running a resistor box.

 

the use of resistor box depends on what injectors your using, and what ecu. if its been ran for 3 years then most likely this guy knew that and set it up accordingly. but for ***** and giggles find out what ecu and injectors you have, and we'll go from there.

 

yeah i too say its prolly already setup to run without. i doubt it would work otherwise.

if youre lookin for a box, i saw a few on ebay today pretty cheap.

 

it's an obd1 P13 ecu. How do I find out what injectors I have?

Upon inspecting the car after I purchased I replaced misc. missing bolts, re-installed the throttle cable and tons of other things that wern't right. I really wouldn't doubt that they completely forgot to put a resistor box when one was needed.

 

running peak and hold injectors w/o a resistor box will fry an ecu in about 30 seconds....so you obviously have saturateds in there....

 

i thought that video said more like 30 seconds....ehh i havent watched it in a long time...

either way, obviously yours are fine...

Sorry to surprise you but they are peak and hold injectors. I am lucky that no damage occurred for 3 years. Needless to say, I now have a resistor box installed.

 

are u sure they are peakholds? because it is alomst physically impossible for an ecu to withsatnd that kind of heat for 3yrs.

what was the resistance across the injectors?

 

sounds to me like you have saturated injectors, especially if the engine is not boosted and doesn't need especially large injectors

The injectors have a resistance of exactly 3-3.1 ohms. They are low resistance injectors which lasted 3 years without a resistor box.

93-96 h22a motors come with 345cc low resistance peak & hold injectors.
