It is a 4.0 DOHC inline 6 w/ VVT and a single turbo. http://autospeed.com/cms/A_2792/article.html

Apparently a tune with no other mods can get you to hair over 400hp and the stage I & II kits can get you up 500hp. http://autospeed.com/cms/A_2794/article.html

Stage III & IV seem silly, if I was looking to spend that kind of cash I'd at least consider an alloy V8 block that might shave a few pounds off of this iron blocked I6. http://autospeed.com/cms/A_2802/article.html

I gather that Ford of Oz is killing the I6 in 2010 and probably going to the lighter, more modern Duratec 35. Ford has already shown turbo versions of this engine making 360-430 hp.

Doubling would be scary. If we extrapolate from the 2.0 L LNF’s 260 hp & 260 ft/lbs then a 3.6 turbo would have more power than an LS3. Ford even said last year that they had a prototype 3.5 L twin turbo V6 with 415 & 400 and I've read that they plan to put a turbo V6 (and a new V8)in the Mustang when the Camaro comes out.

But judging by the LNF & 335 boards, they probably won’t leave as much power on the table as it did in the ‘80s. I imagine getting past 500 would require methanol injection (or E85) and maybe bigger turbos. The big question will be what can the injectors flow and can you get bigger ones.

The Viper motor at NAIAS is probably where I saw it then.
That's the $20 question(s)...how hard is it to upsizes DI injectors?, or how much can they flow?
Once that's overcome, changing: programming, fuel pump, turbo, exhaust, throttle bodies, down pipes, IC's etc etc..will set the horses free.

I can't think of any DI engine with more displacement per cylinder or HP per cylinder so I fear that these might be the biggest DI injects available for a while. Unless the diesels injectors are swappable you may be stuck waiting for the aftermarket or adding port injectors that only fire when the DI system is maxed out.

As for me I don’t think I’d add much more than a tune since I’m looking for a DD. But in a couple years I might start looking for a nice classic convertible that needs a new engine. Nothing collectable, just something mid sized, with a reputation for being a little slow…
