Hey, what's up, does anyone know if a 93 alternator will fit in my 83 rex? Also does anyone know what the amp rating on a 93 alternator is? Thanks

 

well right off the bat NO. the 3rd gen has a serpanteen belt 1st gens have v belts. the plug is like a 89+ alt i think.and i think its 90 or 100 amp

 

Change the puly to a v-belt and you will need to find a wiring adapter if you car is an older first gen. The later first gens had the correct wiring adapter I believe. Ask Yayarx7, he has done this.

 

No. I put a 87 T2 alternator in my 85 GS. It was a plug and bolt in. I think it is rated at 80 amps or so.

 

I know you're asking about a 3rdgen alternator, but when there's only a 10 amp difference and no monkey-crap to put in a 2ndgen alternator, why bother?? Here's that conversion into an '80...look at your plug now to determine if you need to change your wiring...


the easier way to get a big alternator before you commit to a 140 amp $250 monster

Hope that helps...

 

thanks all for the info, the only reason I asked is becuase there is an alternator for a 93 on ebay, pretty cheap too. anyone got a good 2nd gen 80 amp alternator they'd want to sell me?????? thanks

 

There were several 2ndgens at my favorite boneyard but it won't be 'til Wednesday when I can get out there to see if they have the alternators still in them. I'll check on pricing and I can take them to O'reilly's to see if they're good... I paid a $100 to RP for mine, as an asides..is the 3rdgen alt cheaper?

 

so how much was it?

 

right now it's at $36. here's the link

wow $100 bucks for a 2nd gen one I was really looking to spend like $50 at most, but let me know. I'm running a moderatly large system and will have fog lights soon so I want to upgrade the alternator. thanks again

 

That's what I paid because I didn't know better, I was too lazy to do the research and get one, AAANNNDDD I needed it yesterday when I called Rotary Performance. I don't feel cheated because I paid them to get it and send it to me with explicit instructions on the correct mounting and wiring. Now I'm older and wiser and wouldn't pay for one when I can pick 'em up cheaper by myself...

 

Make sure that your wiring can withstand the extra amps. You wouldn't want to be driving down the road ablaze.

 

No problemos so far and this is with an early model Derale electric fan that pulls 30 amps when on...I didn't even change the strut tower fusible link box (Oh, horrors!!), although I did get brand new fusible links...
