you can get a Delco/GM type alternator from Nathan Peddicord at www.excessiveamoerage.com. I got one and the damn thing is bad ass on top of the fact it is 200 AMPS... very easy to instal wiht a small amount of modification. I can tell you how to do it !!

Reading the this and the other page. Does the White/blue wire need to be connected to a live 12v wire or switched 12v wire??

Here is the writeup:



IT'S 100% CORRECT



http://www.rx7.org/public/altxref.html

I use the S6 alt. on my 10th AE. I drooped the lame ass v-belts in favor of the 13B-RE main and water pump pulleys (powder coated = ) They allowed me to use the stock s6 alt pulley.



The wiring is straight forward and no relay is needed. The relay way is Mickey Mouse BS! The shaft on the S6 alt is not only thicker, but shorter (I think MD already said that though) I picked up a 5 ridge (I think it is) belt from Auto-zone. It's a special order item if I remember right.



I went round about, back when I 1st did mine. Lots of wrong info floating around and as a result, fried a brand new alt.



Real quick, if it's done right, no relay is needed or draining the batt. The cosmo pulleys fit kick ass and match up with the stock S6 pulley like a champ. It's pulley is small but needs to be that way to get the most of the alt. Anything larger, will defeat the what where're trying to accomplish here.......13.6 volts @ idle with all the lights on, heater blowing and the big system pounding!! Hell yeah = )



If you like, I get check the the part # of the belt and what wires go where. I'd post a pic but not sure how to on this board.

I think that S6 alternator is more trouble than it is worth. BTW if you got a real FD alternator from a FD wreck or ordered a FD alternator from the dealership like what I did. Those Higgi Alternator pullies don't work on a real FD alternator. They only work on the alternators taht silverrotor sells, so I have no idea what kinda of alternators those are. The pulley seat is too shallow to properly butt up against the bearing that supports the front of the pulley shaft, so if you torque down the higgi pulley on a real FD alternator, the pulley bottoms out on teh alternator casing and prevents the shaft or pulley from spining. I had to take a banzai FC dual alternator pulley, bore it out on a lathe, then make my own shim/spacer similiar to what a FC alternator has.



What a mess, should've just gotten another S5 alternator. BTW the belts are on there really really tight if you use the stock sized belt. So tight I could barely get them on. I tried going one size over, but that is too lose and causes the alternator to sit too high have all the tension loads supported by this little alternator bracket which flexes when the engine revs up and down and the belt slips off.

i'm running the stock FD pulley with cosmo main and waterpump pulleys also. I think i was the first one to do that, anyway, i've got an FD waterpump i'm going to try with the setup. Also have greddy pulleys for that and the FD alt, are you saying that the greddy pulley might not fit because i got my alt from silver rotor? or is that only in reference to the higgi Vbelt pulley? for the tension issue, try using and FD alt tensioner, i just got one.

I can't say enough good things about my set-up. It's bullet proof. The S5 alt doesn't have **** on it.



I tested my second, new S6 alt before I put it on & it's putting out 130 amps!



No slipping belts or back dust all over the place. When I was changing the oil the other day, I tugged the belt because I haven't check it in 8000 miles. It had stretched some & had about 1" of play on the drivers side. Nothing odd there but, I wouldn't of known the slack was there if I didn't give it a pull. Even with that much play and my HP, the fucker was still going without a problem!



I like it when stuff just works https://www.nopistons.com/forums/pub...IR#>/smile.png

himni- does the use of those pulleys allow for the stock fan and shroud to be used? I would assume so?



now the trick is to locate a set of those pulleys!

Just passing by and couldn't help but notice Cheers! post.



Real FD Alternator? You have been spouting this a few times now but now I got to speak up and cramp up your style. You may have got your Impression of this

due to the front casting/lip/ being slightly trimmed to accomadate the modified Pulley. This Is done to the few different types of Pullies we receive. Even for your I'll disputed claims, hIGGI has sold more than 20 FD Alternator Pullies. Some to owners whom I don't even know. Results? The Pulley went In as It was supposed to. Futher and finally I have sold several FD Alternators to FD owners. What do you think I am going to say now? All went well.



You have to seperate our past bout (where I made an example of you In the Canadian Forum on rx7club and In the same thread you foolishly call the owner a rip off ) with reality. Get of the space machine and get laid, seriously.

are higgi and himni the same people?

no, higgi lives in the czech republic.

it looks like im going to try to do the cosmo pulley set up, anyone have any info on that set retaining the AC but no PS?



or has anyone ever used a FD or cosmo AC compressor on a S5 TII motor?

i looked into it, i actually got it setup with the FC PS on a Vbelt originally. You just need to stack the main pulley properly to get the correct spacing. It should be possible to run the FD AC pump if you have the FD bracket. Two of the holes line up with the FC studs, you'll have to drill two and adapt the lines to fit. Getting the lines to fit might be the most difficult part.

Summit Racing sells Taylor braided AC lines made to order, just need to find out if they have the fittings or not, otherwise I might eveb be able to use a local shop that makes lines.

I bought the FD alternator from the evil forum. He included the pulley and the connector plug. I just a straight rewire. No relays. I see 12.5 volts at idle. As soon as I rev a little bit. It jumps to 14.0v and stays there.

On a related note, what component typically craps out on these units? IC Regulator? Rectifier? I had one go bad--it pretty much just quit charging--and swapped it out with the one on my parts car. I really don't have any power hungry devices installed. As little as this car gets driven, I may elect to have the old one repaired or do it myself, then keep it as a spare.

Usually at idle you will see really low volts. This is due to the car not being under any load. So it's really no cause for alarm. In your case, you probably just got the rotten apple. Theese Alts don't have a fetish of going out.



[attachment=38441:attachment]



You don't even have to use the plug for it. I forgot the name of the fitting, but most people use them for wiring projects, etc. I have a plug off a skyline, but didn't want to go through the process of ripping out the old wires and inserting the new ones.

just posting because ill be doing this over the winter

Same here , i get like 12~V at idle and max 13~ with load. Thing is i need to wire in a few things like a new fuel pump, some guages and CDI . All of which is gonna suck juice . And i do not think the stock alternator is going to cut it .



Can the alternator be rebuild to put out more amps ? oh...and pics :P need more pics ..haha.. https://www.nopistons.com/forums/pub...DIR#>/wink.gif

hey whats up people ive got a question i was putting my alternator on my 87, i was tightening the bolt when it snapped and touched something in the process. it sparked when it did this now my car wont start, i checked the fuse box under the hood and the are fine........WHAT THE HELL DID I DO!?! if any one knows what i did please let me know thanks

solenoid?

I'm ashamed to say it but I've had it happen to me. Check the MAIN fuse again under the hood, I think its 80 amps. Thats what I blew, hopefully thats all you blew as well.

does any body know if you can put a FD alternator on a FC?? bought my S4 Rx7 two weeks ago found this guys plans n i wanns do all the things he wanted. so yea message me if you do also how hard is it to do a 5 lug conversion ??

putting a FD alternator on a FC was discussed in detail earlier in this thread- check it out.

btw- here is what I ended up with, I ended up using cosmo main and waterpump pulleys, FD alt and FD pulley, FD AC compressor, FD tensioner pulley for the ac all on a S4 TII power steering delete AC bracket that I had to get modified so that everything would line up.

Re: Let's Do This Alternator Convo Again...
 

Guys my day keeps getting worse. I replaced my alternator, checked pulley alignment with a laser and everything is straight. I still shred belts off. Everything spins freely.
With all the electrical components disconnected and no current, everything WAS fine.
I was putting the B terminal back on the post and I did the SAME stupid thing. The wrench touched my intake manifold and made one little spark and now my car won't start. I pulled the 100amp main fuse I have in my S5 and it's fine. I'm really trying to not get discouraged but this has been really messing me up for work and everything, as this car is my daily. Does anybody have any idea where to start?

Re: Let's Do This Alternator Convo Again...
 

Nobody? This is really detrimental to me as this is my daily.
What kinds of things do I need to check? Fusible links? Solenoids?
All the fuses including the main, are good.
What kinds of things should I do to check the brand new alternator I put on once I manage to get it to run?

The only lights I get when I turn the key to just on are Hatch, Brake, Door, Washer fluid, and Check Engine. The rest try to come on but are very dim. It did this yesterday after I installed the new alternator as well, but it still won't start.
