Have a 01 Integra Obd 2. Going turbo. Can i use this for the resistor box?

Um, personally I don't know you need a resistor box for a turbo. Unless your running obd0 injectors, and an obd0 ECU. The obd0 integras had "low impedance" fuel injectors. (90-91). The obd1 integras used "high impedance" fuel injectors, therefor did not need a "resistor box". Really if you are going to run a turbo, you just need to make sure you have a "tuned ECU" , oil running from your pan or block to your turbo, and ALWAYS use full synthetic oil! Turbos fail when the oil gets contaminated. I run full syn in my non turbo and usually change it every 3000-5000 miles. Granted the recommended interval for Hondas is 7500 miles, but replacing it every 5000 will keep your gas miles up, your sludge down, and give you piece of mind that your turbo is well lubricated!

What injectors are you planning on using?

I think you need the resistor box for the injectors. I have a obd 2 integra so OEM is saturated injectors, and the ones I got are low impedance, so you need to resistor box so you don't blow up your ECU.

I honestly don't know a damn thing about 01 integras. I know obd0 was low impedance, and used a resistor box. Obd1 was high impedance, and did not use a resistor. NOT positive, but I belive the injectors of obd0 and obd1 were actually the same, obd0 just had the resistor. Now for an obd2 system to have to need a resistor, just seems a little backwards to me. I could be wrong! Like I said, I'm unfamiliar with obd2 systems, so don't take my word for it!

Wouldn't the resistor make a high impedance injector a low impedance, and make a low impedance virtually useless?

Reading up on it

After thinking about it, what I said sounds a bit stupid. Low impedance NEEDS a resistor. The main reason I'm confused is because a guy I spoke to selling injectors on ebay, was selling them as 90-93 injectors. I informed him the 90-91 was obd0 and used low impedance and needed a resistor. 92 and 93 were obd1 with high impedance. He replied to me that he has never had negative feedback on the issue. It makes me think I can just pop my 91 injectors into my 92, and since there's no resistor, they will run high impedance. I've seen many threads where people just wired up a resistor to run obd0 injectors on obd1 systems. I have a 91 obd0 engine in my 92 obd1 integra. Rather than take chances I just used the fuel injectors from the blown obd1 engine. Other than that I had to move my o2 sensor and use the obd1 dizzy because I didn't feel like hacking up my wiring. I think the easiest thing u can do, is just get injectors compatible for your ecu. Or get a tuned ecu, which your going to need anyway with the turbo, and ask about compatibility.

You are going to need a Multimeter and measure the Resistance of the injectors in OHMS. At the terminals of the injector clip, there's plenty of videos of how to do this on the web once you get the resistance measurement there you determine if they require resistor box or not, 2.5 - 3.5 OHM is low impendence around 12 OHM is high impendence. low impendence REQUIRES resistor box, high impendence does not. simple thing to do is check if Precision came out with a High impendence injector, im running PTE 1000cc and im running a resistor box, my injectors are at around 3.6 OHMs
