Just read through the entire thread, may have missed the answer to my question, but is a alternator from a 2007 Tundra ok? I know 2007 was a body style change, just making sure before I buy.

Thanks.

^ Maybe. First make sure you check the part numbers. For a 2009 you will need a Tundra with the Tow Package.

Secondly the part numbers that we know work so far are: (I've personally bought both of these alts)

27060-0F040 / 130 Amp & 27060-0F050 / 150 Amp

The 2009 Tundra is listed as 27060-0F070 / 130 Amp, looks identical from the pictures to the 40/50 alt's and is also on a 2UZ engine. So it will most likely work but until someone buys it and tests it....

On our Vehicles. S = White. IG = Yellow or Black-Yellow and L = Yellow-Green

I'm finishing up this swap right now, I'm just double checking.. I don't need to replace any fuses and it's OK to reuse my supra pulley.. Right?

I didn't replace any fuse and I run tons of electricity though my car. Two electric rad fans, two auxiliary cooler fans, two big stereo amps, boost a pump, AC, etc. No problems.

I swapped my stock 90A alternator for the Tundra alternator. And this thread helped me up a lot.

I reused the stock pulley, since it was slightly larger(3mm larger diameter). Car drives great and no warning lights.

I ended up going with Ohio generator. 216 amp , direct fitment, (correct plug and mounting) and a good price.
THIS. I'm really surprised no one else has gone this route?!

Instead of dealing with aftermarket alternators (or even ones from other Toyotas) and worrying about fitment, fabricating bracketry, etc, why not just rebuild your OEM alternator? There are 2 companies out there I'd HIGHLY recommend:

- Startech: www.gostartech.com
- Ohio Generator: http://www.ohiogen.com/html/catalog.html

These guys are VERY well known and tried & true in the sport compact community (RX-7, MR2, etc) community, for those of us running a LOT of continuous drain on our batteries.

I just had Startech do my MR2's alternator. My OEM unit actually had burn out and completely failed. They rebuilt and rewired the entire unit for no additional charge (since they do a full rebuild anyway), and offered an optional polishing/painting/powdercoating service at the same time too!

OEM specs:
- Idle: 20amp
- Redline: 90amp

After Startech rebuild (as high output alternator):
- Idle: 90amp
- Redline: 199amp

Now, when I put the trickle charger on the MR2 after going for a drive, it shows the battery full charged in under a minute lol. Can't beat that!

OhioGen and Startech run around $365, and their warranty matches the factory/OEM warranty: 1 year/12,000 miles. You just need to supply yourself with a high output shielded battery cable with 200 amp fuse, to be on the safe side.

One of their bling alternators:

I just installed my alternator and I wanted to be sure I did it correctly as I am registering a little over 14v at idle with no major change during revving. Assuming this picture is from the back of the plug and that the "IG" and "S" wires are the top (the area where you depress the button to unplug the harness) I wired it into my factory harness like this. S = White. IG = Yellow or Black-Yellow and L = Yellow-Green.

Does this sound correct?
