quest alternator upgrade

[Cpt_Impossible]

How much are we talking? $50

I don't have a spare bracket though.

[mott6904]

Yea that sounds fair but i dont know if i have a spare bracket on my shortblock. Ill check tomorow and see if i have one.

I know this thread is old but, is that for an rb20det?

[Cpt_Impossible]

Yes

[devil_child]

since this was brought back up, you can do the mod to slot the bracket to fit a ka alternator, and the quest alternator pretty much is bolt-on after that. since the pulley was a little crooked on mine, I took a litttle off the front of the mounts on the alternator housing with a grinder and put a washer behind the bottom mount to push it forward.

I made this swap work perfectly and has held up for half a year now with no problems period. I did not have to weld a single thing either.

Ill post a write up when i get around to it here soon.

[HOMEMADE240SXTURBO]

please make a write-up

[devil_child]

just use some imagination and a grinder.

Went to 2 junk yards and yet to find a Quest Alternator.

So I decided to try the J30 deal and it didn't work at all. The covers look very similar but trying to swap them wasn't going to happen. The rb20 was just a little too big for the J30's internals. Not sure what year j30 I pulled it from, but I would imagine they are all the same.

So I'm back on the hunt for a quest and out $20 bucks for the J30 which I guess Ill just use as the core.

[ripracer]

Pulled this off tonight. Took back the J30 found a Village alt. for 15 bucks and little drilling of bottom mounting hole and just cut and weld the Quest/Villager bracket to the rb20's



I suck at welding but hey cranked it up and shes putting out 14.16v, but sadly on stands, hopefully tomorrow. Maybe this solved some of my little issues.

[devil_child]

so my quest alternator took a **** today.

[gawdzilla]

finally got around to doing this with the quest 125a. got it to work but probably would've been better to make my bracket so i could go back to the stock RB alt if i wanted to. someone posted on page 1 with that method.

i had to grind down the lower bolt hole spacer piece as well as the block mount to clear the alt housing. otherwise i couldn't even put the lower bolt through to get the alt to hang on there.

yet to start it up but everything is tensioned and mounted

[StricNyne]

what year was the 125a i thought it was 105 and 110 ? sounds good i got an quest alt idk wut year but i was waiting on my alt to take a **** first

i'm not sure... i bought mine off ebay remanned to like new for $90 shipped. on the ad it says 93-98 quest/villager and claims it's 125a. not sure if i can verify if it really is 125a.

I can provide more details if anybody is interested with my method.

[Darius]

Yes please elaborate. And do you have any better pics that you could take to show what you did. I'm planning on having something fabbed up on Monday night.

[ninety1two40]

Ok, I don't want to remove the bracket but I'll take more pics and make a diagram. It's really simple.

[l0nestar]

Stock _is_ 110a for a 94 Quest.

The only way that I know of to verify the amperage would be to remove the alternator and set it on a test rig.

ugh the more i think about it the more i should've done it your way. just requires a bit more hardware but being able to go back to oem is key.

Darius - start with the mock up first. get the alt swinging on the block (that takes a bit of effort). then once you have it swinging you can really see how the bracket is to be made.

i was thinking maybe different models of Quests with different options that require more power.. i dunno like rear stereo/accessories might have them offer 2 different alts amperages. not too sure. but either way it's an upgrade and remanned part to replace old.

let me guess, you're using spacers LOL

[gawdzilla]

let me guess, you're using spacers LOL

he made an adapter bracket that lets you tension the quest alternator using the RB tensioner setup. it is a great idea. i can see what he did but its difficult to tell if you hvaen't played much with the setup:

I know this is an older thread but it seems like a good place to post this so people can find it easy.

I used an alternator from 1996 Nissan Quest.

Instead of chopping up the stock alternator bracket I decided to make an adapter that would allow me to still use the belt tensioner and give me the option to go back to the stock RB25 alternator. I had to enlarge the lower mounting holes on the alternator. But I didn't have to modify the block or the alt bracket.

I basically welded two angle pieces together and drilled two holes. I'll try and get a better picture soon, but all I had at the time was my camera phone.

BTW: I'm still new to welding

[ninety1two40]

Ok I took like 4 pictures but only one is clear enough to tell what's going on. Also, I had it powder coated a few months back when I had my valve covers coated.



I'm going to look around for a piece of steel and just make a quick "how-to".

[ninety1two40]

Here's a quick write up I made, nothing fancy but I'm sure it would answer most of your questions.

BTW, I have been running this setup for about a year and no problems what so ever.

Good idea writing a PDF!

I had wondered about that as well, but there is only one part no for a Quest or Villager.. and it is 110a. At least according to Napa, Advance, and Auto Zone. We just got an O'Reily.. I did not check there..

I noticed with some alternators that I have bought from Advance Auto and Car Quest, put out more power than is listed. Most new alternators come with a data sheet and plot of the output current vs. rpm. Every alternator isn't exactly the same.

Wow guys. I didn't realize how much of a PITA this upgrade would be. It sounded like "eh, drill out the alternator hole, grind the block a little, make a bracket and POOF! it's done." Not that easy.

I had to grind the block down about 1/8" on the outside of the lower mount. Then I had to grind the spacer flat on one side taking about an 1/8" off of that. THEN, I had to sand down some of the alternator housing ribs to get it to clear. And it still interferes a little on rotating it. Totally sucked. Took two guys 4.5 hours and a full machine shop...way longer than expected. Even after all of that, the lower bolt is too short to tighten down the alternator and I ended up having to slap the stocker back on to drive home. Pissed me right off!

I will say that the bracket we made is 10X easier and cleaner than anything I've seen so far. Check it out below! (2" of 1/8" steel flat bar, ~4" bolt, ~1.5" of spacers, nut, and a short bolt matching the threaded alternator hole)

Here are some camera phone pics of what I mean.

Looks good Darius

[Darius]

I'm at work right now and want to go to the hardware store to get a longer lower alternator bolt. Does anyone know the size/thread of this bolt? I can check it tonight, but I wanted to save some time.

[cdorhout]

SEARCH NOOB!!!!

ohhh LOL coming from a newb NRRBA member! Have you paid your dues yet buddy?
