larger throttle body

[Stang5o84]

was wondering if anyone knows of any aftermarket throttle bodies for the 4.6? Also performance injectors.

None exist. Best bet is to P&P your existing throttle body or pick up one from a junkyard and have it P&P

Thanks!

Do you know about fuel injectors, if there is any better options for aftermarket parts out there?

Yo bottom line if you want something performance for these cars you make it yourself.

It wouldn't be hard finding an injector that will fit, it's tuning that you'll have trouble with. BTR isn't tuning the 4.6 or 5.0 anymore.

I've been wanting to do this on my 3.8 I know a guy who does a ton for the coupes. Beautiful work. He's working with a custom fabricator on the side as well to hopefully start building a true CAI for the sedan hopefully that turns into risers, headers, super charger? I know they make turbo kits. downpipes, etc..

So there must be equipment out there too manually tune it yourself.? I mean how do the race shops tune vehicles?

It's a matter of having a way to modify the parameters in the ECU. Not all cars run the same software and unfortunately there's not enough people interested in modifying these cars for a company to invest R&D into other mods beyond intake and exhaust. Especially a tune since you don't pick up much power on an N/A engine in most cases. That's why the aftermarket support for the G70/80 and Stinger is much greater, the turbo engines pick up way more power and so it's easier to sell.

That sounds right,
I think what I'm going to do is get a used throttle body and bore it out, then do the same thing and port an intake manifold. Then probably pull the heads and send them to a shop to have them ported, and that will be about all I can do with the car by the sounds of it. Well besides exhaust but I'm worried at the new exhaust would be allowed I really like how quiet the stock exhaust is

People are not listening.
THE STOCK ECU WILL NOT ADJUST BASED ON PERFORMANCE MODS.
You are just dumping $$$ into mods that will return near zero return.
Save your money, trade in your Gen for a TT 3.3 and then mods are possible.

+1 exactly.

These are low volume luxury cars. There is zero aftermarket support outside of lowering kits and a few cosmetic mods, all parts are OEM sole-sourced parts (HMA).

The Genesis 4.6 is an impressively well-performing engine from a HP per Cube point of view (385 HP / 280 cu-in = 1.375 HP/cube). Compare the performance of the 4.6 Tau to the 2012 Mustang GT 5.0 made 412 hp, or 1.36 hp/cuin. Slightly less hp/cube than the 2012 Genesis 4.6. The 2012 Camaro 6.2 made 426hp, or 1.13 hp/cuin. That's tells you something about just how good the Tau engine is from the factory.

Bottom Line: The absolute single best performance mod you can make to these cars is a good set of tires. Michelin PS4S will do you right.

But if you have the HP mod bug and you just cannot live with yourself unless you modify a v8 car, pick up a used 2010-2012 mustang for about the same price as a used 4.6 sedan. Mustangs are everywhere and cheap to buy (compared to Camaros and other v8 performance cars). Mustangs are very easy to mod & make big power and there's a staggeringly huge aftermarket that borders on the incomprehensible. Figuring out what to do with all the options available takes longer than actually doing the mods.

Or...

Be happy with what you have. A kickass luxo-barge!
