alternator upgrade.

[ryan1]

ok im looking at upgrading my alternator. After all these years in the bg world and all the different mods i have done to many different bg's, I have never upgrade a alternator.

So with that being said im looking/weighing my options, so whats out there?

I have searched this a few times but nothing has really been documented, or it to old the links dont work.

I would also be fine with upgrading to and non v belt set-up if it would would work with the small nosed crank BP.

milli v6 alt. oem denso is 105 amps. You will have to swap pulleys to a serp drive which can be had off a bp kia sephia 96-98 I believe.

The mx3 v6 alt is 85 or 90 amp and and I think the mpv alt works as well. The 89 rx7 alt is 75 or 80 amps turbo and non turbo.

eBay has a 120 amp alt for about $140 from ace auto listed under the 89 rx7.

You may also want to look into the big 3 upgrade if you are into car audio and may run a 2ndary battery like a XS Power XS750.

start with the big 3 even if your not into audio.
what major draw items do you have besides normal headlights/ distributor setup?
foglights/COP's/audio/exotic setup??

the KL alternator is a great step up (90 amp vs 65 OEM). elsewise I highly encourage a 140/120 amp alternator(I got my 140amp from ebay)
the 90amp will make your car run entirely different. significantly smoother. it will leave you wondering why OEM put on such a small amperage unit.
I highly encourage you to stay away from the millenia alternators. the plugs on them are exceptionally delicate & like to break, which can lead to a whole different world of issues.

Is this the one you got? http://pages.ebay.com/link/?nav=item...759905&alt=web

[FE3-323]

no, i would have to look back to last year or so to find the one i bought. thats a 120 amp. mine is a 140 amp unit.
120A is plenty sufficient for our usages.

I usually buy fro ace on ebay. The highest they have listed right now is the 110a: http://www.ebay.com/itm/1993-Mazda-R...item2310e9e388

Ryan, the 626 v6 and mx3 v6 uses the same plug as the bg?

We need a v belt pulley option as
1) you could sell those v belt pulley's like hotcakes for a cheap alt upgrade that's readily available and
2) it would be plug and play.

[FE3-323]

normal KL's use the same plug yes.

This would be for my bp turbo swapped bf gtx, stock audio,aftermarket fog lights, possibly h.i.d. conversion.

I just want a nice rock solid set-up as this will be daily driver in the winter.

Not saying im going to go this route, but is there crank pulley that is set-up with a serpentine style alternator that works with the small nosed cranked bps?

[azgtx]

Mx3 B8 uses a serp belt but not an amperage upgrade. The 89 RX7 uses an 80 amp that I use on my gtx's but then I am still using the narrow v belt pulleys.

[FE3-323]

90amp for sure!

Sorry to sound like a noob but what's the big 3 upgrade you guys are talking about?

My GT could use an alternator so might as well upgrade so this thread is a good read lol

I don't think we got the BP Sephia up here so if someone has a pulley kicking around, I'd be interested in one

[FE3-323]

its the 3 main power leads/lines

per example. alternator to battery, starter to battery, battery to fuse block.

Here are some pictures of mine. <<<<<<

alternator upgrade.

Ah ok gotcha thanks Ryan

[ryan1]

Mx3 B8 uses a serp belt but not an amperage upgrade.

Is that a small nosed crank on the mx3 b8's?
what years?
Thats fine that the b8 mx3 do not have a upgraded alt, as you could use a nother model higher amp alternator but could use the mx3 crank pulley for the upgrade.

B8 MX-3? When did this happen?
