Where can I find upgraded performance parts for my 2010 F150? It's got the 4.6 2v, which is a significant bump in ponies compared to the 89' Camry I traded in for it, but I'm wanting more. I currently have a custom Flowmaster side pipe on it, which sounds great. But, I would like to put a slightly bigger cam and forged internals into the motor. A supercharger (twin screw roots style), and an intercooler. However I've got no clue where to look. I've got no warranty, so I figure just go wild.

Tuner is the most cost effective for the money

I agree with you completely. However I don't like the idea of pushing my stock engine components to the maximum, because to me that's just asking for trouble. Also I want to see north of 600hp, this isn't just a project to terrorize the streets with, I want to also take it to drag events. While also terrorizing the streets. But I want to build the power I want reliably and safely, so putting in stronger parts is the most logical way to do it.

With the 4.6L a lot of the Mustang parts transfer over pretty easily. You'll still need a tuner to make it run right though. For power upgrades, a blower or procharger seems to be the next best thing for more power. With the right tuner you can monitor all the engine characteristics such as air-fuel mixture to make sure you are running safe. To safely push 600hp out of that motor though, I'm afraid you'll have to build the bottom end. I'm not saying it's impossible to do with a stock block, but it'll damn sure put undue stress on parts that aren't rated for it. If you have the funds, a built short block would be the way to go. Then you could add the power adders as you have the money for. I think some of the Mustang vendors on the other forums have forged kits for these engines. Might be something else to look at.

Also, a custom tune is what will push the internals to the possible breaking point. The "canned" tunes are still on the safe side of operation.

No matter how much $$$$$ you throw-at the 4.6L 2V it would not be co$t effective and have little ROI.

Better to save-up for another F-150 with a more performance oriented engine.

Don't get me wrong ... the 4.6L 2V is a durable, reliable engine, HOWEVER, takes $$$$$ to get high HP/FtLb. And then it's not durable, reliable.

Trick-flow makes a complete top end kit for that motor.

Bbk performace makes a lot of parts for the 4.6 . Jegs or summit for cams. Theres more sites out there just got to look

Can't speak-to the 5.4L (2v|3v), however, I've had a few 4.6L 2V (and one 3V) and a current one in a Crown Victoria that was purchased new in 2002. Currently has 125,000 miles, last oil analysis indicated no wear, can still chirp the tires going into 2nd gear (3.73 RAR), turns 14.7 sec ¼ mile times, and gets GREAT fuel mileage (worst 20-22 city, best 31 highway). NEVER said that the engine wasn't dependable, durable, etc., etc., etc.. DID NOTE that for LARGE performance gains there isn't a good ROI for the $$$$$ layed-out.As for the performance mod's to the current 4.6L 2V, bolt-ons (UD pulleys, ported/polished throttle body adapter, 70mm throttle body, Marauder airbox with 80mm MAF, and a 87 octane dyno' tune) have netted what is to me acceptable performance gains without HUGH amount of $$$$$. BUT THEN ... You're talking about only 25HP and 20FtLb RW gains. Anything more and you'd be dealing in über $$$$$ and RPM ranges in the high-end.

I also have a 4.6 V8 in my 2002 SuperCrew, it's a great reliable engine, but I never did any performance mods to it, mainly cosmetic. Joe is right, you'll have a small return on your investment if you put any money towards performance upgrades.
