getoffmyinternet Posted November 26, 2007 Share Posted November 26, 2007 So I'm guessing you're stonehac? Dang, every time someone finds one of these on ebay I'm too late and only see the ended item. Well at least there was a buy it now this time for ya so you couldn't be outbid. Quote Link to comment Share on other sites More sharing options...
stony Posted November 26, 2007 Author Share Posted November 26, 2007 Yea sorry i wasnt gonna wait on this one :> Quote Link to comment Share on other sites More sharing options...
WizardBlack Posted December 1, 2007 Share Posted December 1, 2007 Looks almost precisely like many other resistor boxes I've seen. Another poster pointed out that most japanese low impedance 6-cylinder cars will have precisely what you need. Heck, you could probably use a V8 box if you saw one somewhere and use it as well.

getoffmyinternet Posted December 1, 2007 Share Posted December 1, 2007 It's quite possible. Also, I found the stock box on RHD Japan if anyone is desperate enough to pay $60 or so. Their parts seem to be somewhat overpriced by 30% or so. I'm just gonna build my own at radio shack like they say. Besides, the plug isn't going to work anyway, because the plug that heads to it on the harness goes to another plug first. I'm about to post a blurry picture of that plug on my progress blurb. Perhaps others have something different. Quote Link to comment Share on other sites More sharing options...
Careless Posted December 3, 2007 Share Posted December 3, 2007 does anyone need a legit part number for this thing.... or? Quote Link to comment Share on other sites More sharing options...
getoffmyinternet Posted December 3, 2007 Share Posted December 3, 2007 I finally found it on Fast! rb26dett: 22698-U5U10 I tried to use the part code to find the part number for the rb20det but it said it was not applicable. Quote Link to comment Share on other sites More sharing options...
Careless Posted December 4, 2007 Share Posted December 4, 2007 I finally found it on Fast! rb26dett: 22698-U5U10 I tried to use the part code to find the part number for the rb20det but it said it was not applicable. 22698-05U10 works for both RB25 and RB26 perhaps because they have low impedance injectors. RB20 would then use High Impedance, because I also did a search for "RESISTOR" and I found RESISTOR-DROPPING, but it didn't cross on the RB20 at all. And it does not cross with anything in the US either. Quote Link to comment Share on other sites More sharing options...
Booztd 3 Posted December 5, 2007 Share Posted December 5, 2007 I think I typo'd in my original Radio Shack post......the resistors you're supposed to use are 10watt/10ohm, not 6watt/6ohm as originally stated Quote Link to comment Share on other sites More sharing options...

Stealth-Z Posted December 6, 2007 Share Posted December 6, 2007 boooooo. now i gotta go change my illustration!! Not so fast on the changes. Do not forget I have measured the resistance on a stock RB26 resistor pack to be 6 Ohms. Quote Link to comment Share on other sites More sharing options...
Careless Posted December 6, 2007 Share Posted December 6, 2007 LOL I couldn't edit them anyways, but I did edit the image itself in illustrator. Good call, i'll just leave it as is. Quote Link to comment Share on other sites More sharing options...
Booztd 3 Posted December 6, 2007 Share Posted December 6, 2007 Could be, maybe radio shack is playing games I could have swore when I went there the first time the ones I bought were 6w/6ohm but when i went there last week they only had 10w/10ohm and no place for the 6'ers.....

stony Posted December 6, 2007 Author Share Posted December 6, 2007 Well i guess all someone would have to do is measure the resistance of a low impedance injector and compare it to the Stock hi impedance injector right???? The get a resistor to compensate for teh difference. Anyone have a set of the stock 444c injectors? I have a set of low impedance 1000cc injectors i will measure tonight and post teh results.

getoffmyinternet Posted December 7, 2007 Share Posted December 7, 2007 When did you start saying "teh?" Heheh. So now I'm all screwed up. Is it 6w 6ohm or 10w 10ohm or 10w 6ohm????? I have stock injectors. Are they all high impedance? I was thinking there were variations depending on setup. I don't know much about them, or what the difference in result is for that matter. Plus, the book I got on CD says different things. I'll have to check it again for what the resistor is said to be on the 26. Quote Link to comment Share on other sites More sharing options...
stony Posted December 7, 2007 Author Share Posted December 7, 2007 teh, adn, and various other 3 letter words for some reason my fingers get out of order :> Quote Link to comment Share on other sites More sharing options...
mannyvig Posted December 7, 2007 Share Posted December 7, 2007 Ran into this same problem a few weeks ago. Read 4ohms across the 444 injectors and 13ohms across the rb20 260's. Ended up using 10w 10ohm resistors. I really doubt you will easily find anything else. Quote Link to comment Share on other sites More sharing options...
Stealth-Z Posted December 7, 2007 Share Posted December 7, 2007 Just measured two sets of stock 440cc RB26 injectors and two sets of stock 270cc(?) RB20 injectors. Stock RB26 440cc injectors measured a near consistant 1.7 ohms Stock RB20 270cc(?) injectors measured a near consistant 13.4 ohms The difference between a Radio Shack resistor rated at 6 watts vs. 10 watts is its heat dissipation. More wattage rating = better heat dissipation. Quote Link to comment Share on other sites More sharing options...
zilvia_gt Posted December 12, 2008 Share Posted December 12, 2008 Hate to bring up an old thread. But it seems like there really wasn't any closure on this topic. Is the 10ohm 10watt or 6ohm 6watt resistors that is needed? The last couple of posts seems to be leaning towards the 10's. Quote Link to comment Share on other sites More sharing options...
Zmanco Posted December 12, 2008 Share Posted December 12, 2008 I ordered 6 pieces of 6.2 ohm 10W resistors from Mouser. I wired 3 in parallel for each bank of injectors creating an effective resistor of 2 ohms 30W. The Mouser part number is 280-CR25-6.2-RC and they cost $1.09 each a year ago. If you assume a worst-case resistance of 1 ohm for the injector + 2 ohms for the resistors, then you have roughly 4 amps current. That equates to ~30 watts being dissipated by the resistors IF the injectors had a 100% duty cycle. Of course they don't and the injectors are closer to 2 ohms, so you might be able to go with smaller resistors (say 5W), but I wouldn't do it as the resistors will run hotter and could cause issues with where you mount them in terms of heat dissipation. The key is you want to get to ~2 ohms resistance with ~25W capacity. Quote Link to comment Share on other sites More sharing options...
Zmanco Posted December 12, 2008 Share Posted December 12, 2008 One more thing, these resistors have solid wire leads (not stranded) so it's important to mount them so that the wire leads don't move around and eventually fatigue and break. I mounted everything on a piece of masonite under the passenger seat and used zip ties to hold them to the board. Quote Link to comment Share on other sites More sharing options...
