alternator upgrade

[andrew22888]

I'm not exactly sure about different the pulley setup and such is. But I know in a 91 crx. A 89 chevy v belt alt bolts right up to it. And those are 120 amps

How much power do you plan on running?

this is about 70 bucks more then the stock one and its 50 more amps

If the alt is from a 2.2 it should work just fine. I was thinking it was a 140 amp alt from an odyssey with like a v6 or something.

A v6 alternator might fit but the belt may slip under heavy loads.

Why would there be any slipping? If the belt fits and the alternator is adjusted so the belt has proper tension there should be no slippage at all, should work just as a OEM alternator.

How many amps does a stock accord alternator put out?

[jdm92_accorn]

stock accord is 90amps and h22 prelude 92-96 is direct bolt on except for swapping out pulleys. and its 95 amps. napa sells it for about 15 or 20 more than the accord one and it has an actual output rating at a given rpm right on the label. honda rates is at 95 put mine from napa is rated 110amp@6k and 95amp@3k.

the acura legend alts fit too but they are only 120 amps i believe ( g1 legend ). gen2 legend alts should fit as well but i am not knowledgeable of the exact output amps. best bet is the honda odyssey alt @140.

I'm not gonna bother going into the insane amount of detail it takes to explain why, but basically the best explanation is that if your alternator puts too much drag on the pulley system, the belt will slip. Your best bet for someone to explain it would be to ask someone like Rob @ DC Power or Mechman.

But a 5th gen Accord with H22 motor, would that alternator swap over? I assume so, unless it's OBD 2 it might not.

this is a cb7 alternator, output 80amps

this is a prelude vtec alternator, output 90amps

this is a 94 legend alternator, output 110amps

this is a 99 ody alternator, output 130amps

[Tippey764]

im pretty sure the legend or 99+ odyssey alternator won't fit

What about a 95-98 odyssey alternator?

[sonikaccord]

The legend won't fit but it looks like the ody will. Just repin the harness to the square plug.

[jdm92_accorn]

the ody just barely wont bolt up. i was curious and i had to go up to autozone anyways to get some plugs to i checked the measurements for the ears and its off buy just a little bit. but the cases are very similar so i wonder if you could just swap the guts.

[sonikaccord]

Is it like millimeters off?

sup guys, im thinking of getting one sub with 600watt amp. Would i need a new alternator too?
