130A SC430 Alternator Mod For 2JZ

This was a mod i did on my sc300. I wanted an oem Alternator with the new hairpin style stator, and the oval 2jz plug... SC430 Alt. is it. Im running: A walbro 450, is300 fans, Heater,defroster,wipers and voltage sits at 14v at idle... Good enough for me.
Alternator puts out 65A at SC430's idle... My idle is around 950 so its a bit higher which bumps up the amperage a bit.

Awesome Sauce bro!🏁🏁🏁

Did you do the fuel pump bypass mod? Will it gives more of a consistent voltage without/with fuel pump bypass?

[@gabrielalejandro1600]

It uses the same exact plug as the existing 2jz plug? Not requiring a re pin?

[@BoostedLexus]

Correct plug does not need repinned. I'm still using this alternator today... Great alternator. 14v almost all the time.

I'm trying to do the gauge upgrade too on my 2jz but I'm a bit confused with the headlight cable relocation. What exactly did you do? I'm following the supra forums 4G wire upgrade to the alternator post and I've hit a wall. Can you please help? Thank you.

[@BoostedLexus]

Email me @ [e-mail] I'll try to help. I have not done a headlight cable relocation but I can try and help you figure it out.

[@bm2409]

Did you swap the pulleys ? I notice the 2jz pulley is bigger than the sc430 one

[@BoostedLexus]

I did not, I kept the OEM one from the sc430. I didn't notice any weird charging or issues in high RPMs

[@juantoolsdowork421]

Hey how did the bottom bracket work,where the bottom bolt is?..does stay the same or you took it off?

[@BoostedLexus]

The bottom alternator mounting bolt is still on, I bolted the bottom and top bolt just like the OEM alternator mounts... Upper mounting on the new alternator needs grinded down a bit and and the middle mounting gets cut off (not used)

[@juantoolsdowork421]

Thanks....btw im goin to use the 150amp from the sequoia. Looks just like that except the plug .

[@BoostedLexus]

@@juantoolsdowork421 Yeah, I thought about using the 4pin 150amp alternator, but got a good deal on this one brand new and plug and play... Deal. Lol

[@anthonyhoward4071]

What year sc430 did you use for the alternator?

[@BoostedLexus]

2003-2010 they are 130A

[@Ma70.Vader_89]

Got any pictures of the alt after you modified it?

[@BoostedLexus]

My Instagram might have some, if not, I can take one mounted on the engine.

[@jaynove]

nice info, how is the alternator holding up?

[@BoostedLexus]

Currently still putting out 13.5v - 14v and running great.

[@jaynove]

Boosted Lexus that’s badass

[@jimmy396jimmy]

did you get an denso? or aftermarket?

[@BoostedLexus]

I got an aftermarket from Advance Auto

[@jimmy396jimmy]

@@BoostedLexus sweet man thanks, just ordered mines. My stock alt in my supra can't even handle the ac on full blast with the low beam headlights and fogs on.

[@BoostedLexus]

@@jimmy396jimmy this will work good for you, at idle it produces about 50 to 60 amps... I have is300 fans and they come on, with heater, sound system, fuel pumps on, and I see 14.2 volts... She still running in the car today.

[@cherryflake2946]

going with a 150A sequoia wish me luck

[@guglegugle8075]

Have Toyota part number? Is 27060-50280? Correct?

[@BoostedLexus]

That looks about right sc430 Alternator.
