MK3 Supra Horn Thread

[modmonster2008]

I don't know if this is "sticky" material or not, but I found a great upgrade over the stock mk3 horns! I was inspired by a guy who swapped over Lexus ES250 horns on his MKIV Supra they sounded great. Believe it or not it made the stock dual tone horns sound out-of-date. I went to the junkyard the other day and found no ES250's but I saw a Lexus SC300/400 That had the dual horns (not the ones that we have stock), It is plug and play although you may have to alter the positioning of the horn a bit on the driver side as it will hit the coolant expansion reservoir. Time it takes is around 15-20 mins max.

Tools needed:
12mm deep socket wrench (no need for extension)
Pliers
WD-40 or some contact cleaner

1. Open up the hood and locate the two factory horns.
2. Remove the coolant tank out of the way to have easier access to the horn.
3. Loosen the two 12mm bolts that hold the horns and then undo the wiring harness.
4. Remove the two bolts and take off the stock horns.
5. Apply WD-40 or contact cleaner to the wiring terminals for good connection
6.Mount the Lexus SC300/400 horns on the car. (these next two steps are important)
>The H (high note) horn will be placed on the passenger side
>The L (low note) horn is to be placed on the driver side
7. Position the two horns so that water cannot get in the horn opening.
8.Tighten down the passenger horn first, the driver side will need adjustment to
prevent hitting the coolant tank
9. When final adjustments have been made, tighten down both bolts.
10. Reinstall the coolant tank and test out your horn.

They look almost factory made for the Supra, they make the mk3 sound way better too in my opinion, try these out for yourself, you'll definitely love the upgrade!

...Now I need to find an sc300/400 in a junkyard. That may be harder than finding a supra.. which i have yet to do.

Exotic would be a Ferrari horn...too funny to watch the reactions to that one!

Good write up. I did this a couple of years back and enjoy tappin' on the horn and not sounding so wimpy.

Lexus horns were one of the first mods I made to my Supra

(sorry for the newb talk, I was young and ignorant)

I made that thread and shortly switched over to SC400 horns

while i appreciate this mod, i'll prolly just go with the $20-30 HF air horns

train horns FTW! im thinking about throwing a siren from an alarm system in too, as a "IM REALLY PISSED OFF GET OUT OF THE WAY!" horn.

One of my horns is out. It sounds like such a little bitch now.

DON'T They suck so bad it's not even funny. Mom's miata had them when we bought it, my stock horn on my supra was louder... They're knock-offs of the hella air horns, buy them instead (like I did for the miata) and be happy you did.

Honestly, the stock supra horn sounds great, but if the wiring is bad or they're rusty they sound like crap. My opinion, but I like their tone over other horns.

Put a train whistle on your BOV and use that lol.

I'd love to do a train horn (or a semi's horn would work too), but I can't seem to figure out a good place to put one unfortunately. Not exactly like we have tons of room under the hood... I'd be careful putting anything resembling a siren on your car though, the sound could give people the wrong impression and next thing you know, you're faced with a ticket for impersonating an emergency vehicle. :nono:

In all honesty though, I've found that the horn on our cars is a lot less noticeable than the exhaust, if I need to make sure someone notices my presence (like the time I almost got ran off the road by some old fart in a Chevy truck), I just clutch in and rev it quick and sharp.

my buddy at work was telling that he hooked up a momentary switch to an alarm siren, so if you hit it right it sounds like a whistle, like if you were to lock the doors, just that quick little, "WEE WEE". lol just for the ladies

e36 BMW horns sound nice.
