cobrAA Posted December 26, 2013 Share Posted December 26, 2013 Actually, I'm speaking with a company in USA.. they produce 220amps ( https://www.dcpowerinc.com/high-output-alternators.html?make=Nissan&model=Quest) I sent them an email and they are currenctly beta-testing one for a RB in a 240sx.Should be available this winter once they done with testing and said I will be the first one to order one Link to comment https://www.sau.com.au/forums/topic/436765-high-output-alternators/#findComment-7153741 Share on other sites More sharing options...

mattie4270 Posted December 26, 2013 Author Share Posted December 26, 2013 600+ KWs,fuel systems alone takes 32amps,ive already blown 2 secondhand alternators and the brand new one im using is getting very hot!As im an electrician i understand all your electricals should be at least 150% overkill for reliability.Checked out the RH9 mentioned above,sounds the goods,but $1000 once you ship from UK,found a website in Japan that can get one to me for $610,this will be my christmas present.Thanks for the help guys Link to comment https://www.sau.com.au/forums/topic/436765-high-output-alternators/#findComment-7153861 Share on other sites More sharing options...
Piggaz Posted December 26, 2013 Share Posted December 26, 2013 RH9 will do it with ease until you're running 11ty pumps. Bolts straight in and does the job.

cobrAA Posted December 26, 2013 Share Posted December 26, 2013 What are you running to warrant 150 amp? add fuel pump and audio amp and your in for at least 150.. so if you want a bit of space in case of.. then you need a 180 amp.. Actually I calculated I needed about 200amps. I bet my ignition and throlle will feel snappier once I install the new alt.

discopotato03 Posted December 27, 2013 Share Posted December 27, 2013 If you want Nissan OE the go seems to be later Maximas with all the elec options . I know we got Hitachi 110 a alternators here but the belt tensioner mount is in a different position on the I think front casing . I have a 110a one here gutted for when I get around to needing an alternator , for me 110a replacing 80 should be fine . I never got around to researching Mitsubishi alternators to see if there's anything better than 80 for an RB25 that's direct fit . Something to remember with high output alternators is that the rotor is usually considerably heavier so revolving inertia to have to accelerate and decelerate . Note the pulleys get wider for contact area so they don't slip . Also some big late alternators have some wacky decoupling guts type pulleys I think so the alt can run faster than its pulley sort of like the free wheel on a pushbike . Probably makes life easier for the belts and off throttle engine transients . A .

turb33gtst Posted December 28, 2013 Share Posted December 28, 2013 either RH9 hyper alternator 130 amp or Advance Black Alternator 130 amp both about same price you can get for under $600 from www.rhdjapan.com cheaper when they run weekend specials difference between both is just Cosmetic first is Blue & Silver ( blue pulley ) & the second Red & Black ( red Pulley ) got my RH9 within 6 days from them to Country Victoria.

discopotato03 Posted December 28, 2013 Share Posted December 28, 2013 The ones to research are late luxo barges that had a filming studios worth of electronic poser crap . These often have high output alternators to run all this crap at virtually idle for traffic driving . Unfortunately we didn't get the real Nissan lux sedan , Infinity , like they do in the states . We got fobbed off with the Maxima FWD POS though the real one is available here now . Also worth researching late four tonne drives because these are often rolling lounge rooms with all the crap as well . A .

discopotato03 Posted January 3, 2014 Share Posted January 3, 2014 (edited) I had a bit more of a sniff into Mitsubishi brand alternators since some Skylines have them and it looks like its easier to have a win with them than later Hitachis - exc maybe late Maxima 110a ones . So far the highest output one I've found is off a Mitsy 4B11 and it's 12v 130a . Search for 130a Mitsubishi alternator because I can't post the link . Also things like RX7 Ser 6 7 8 and Pajeros have Mitsy alternators in the 90-110a range . Be good it their guts went into Skyline Mitsy casings , cheers A .

Shoota_77 Posted January 3, 2014 Share Posted January 3, 2014 Can an alternator rewinder/repairer bump up the output of a standard alternator? Obviously they'd need to change regulator as well but wondering do they add extra windings or something to bump them up?

mattie4270 Posted January 3, 2014 Author Share Posted January 3, 2014 Yes they can,but only old school auto electricians can do it,and can be quite pricey.Thats what we did years ago,remember turning a 25amp one up to 45amp for a torana,that was hi tech in the day.Much easier now just to buy one.

r33_racer Posted January 3, 2014 Share Posted January 3, 2014 I fitted one from a 2010 turbo diesel patrol I think...not sure exactly what year it was, but it didn't have the vacuum pump attached to it. I believe it was rated at 130amps also.. Was about $500 brand new from Nissan spare parts. It was not a direct bolt up though, I did have to machine up a linkage so it could still adjust belt tension. Bolted to the block the same but the lug to pick up the slotted adjuster bracket was in a different spot, hence the linkage.

discopotato03 Posted January 4, 2014 Share Posted January 4, 2014 I found another possible in Nissan Muranos , I think they have a Hitachi 110a alternator 2003-2010 and a 130a from 2011 to 2013 ? BTW can an auto sparky tell me if you have to wire up the 3rd and 4th pins used on later alternators ? I think the engines computer must have some control over charging loads possibly for emissions BS reasons . A .

Brandon Posted January 6, 2014 Share Posted January 6, 2014 Anyone can provide some confirmation as to the RHD Hyper Alternator is a straight bolt on replace of a R33 GTR or any skyline for that matter?

Sinista32 Posted January 6, 2014 Share Posted January 6, 2014 hi Brandon - I had the RH9 Alternator installed on my R32 GTR just prior to Christmas. It was direct bolt on. However, they did put a new inline fuse in mine. Will find out the ampage and reason in the next day or so.

However, they did put a new inline fuse in mine. Will find out the ampage and reason in the next day or so. Cool. Please do. By the way, do you know if the alternator comes with voltage regulator or are they external? I'm wondering if that might be faulty. Any case, I've placed an order for the RH9 alternator, hopefully its all good.
