Wow...Just...Wow dude...Do you even realize how much power your talking about? I'm not trying to offend you man,but come on...1000HP Daily driver 5.4 twin turbo thunderbird ? maybe if you had 50-60 grand to blow, but 6500 bucks isn't even gonna pay for the machine work and fabrication your gonna need for the kind of car you are describing...

And with 1000 hp anything your not gonna get good mileage, and that's if you can even run street fuel...race fuel is probably gonna be way more than $5/gallon

1000 HP? You can HEAR the fuel tank gurgling ... http://www.motortrend.com/roadtests/...e_first_drive/ for a 1200HP car. Also, you may be able to push emptying the tank as fast as you can fill it up.

Blake's post x2...

You have A LOT more reading to do. I got to ride in my uncles a 600hp 427 '65 AC Cobra and it was stupid fast. I wouldn't want something with that much power for a daily driver. LOVED IT. But NOt for a daily driver. I can't even imagine what a 1,000 horsepower car would be like.

I just dont understand these modular engines then. My uncle has a twin turbo 427 sbc that makes 800+ hp that he can turn the boost down and runs 550 hp on the.streets getting10-12 mpg. Guess it just doesnt work that way with fords.

Not arguing you guys just seriously don't understand why everything seems so complicated for these modular motors.

This is what's going on. You're comparing a 427 to a 4.6. Just that alone is worlds apart. Do you even know what the "427" actually refers to?

being one of the few that went down the road of turbocharging in a MN12 chassis I will say that the space is tight under the hood. A turbo setup will need to be custom fabricated. There are no kits that will just bolt on. Is it doable? Yes but takes time and lots of cash. I was going the low budget route back then which takes even more time and money. I lost interest in gas motors a while back. there is only one guy w/ a MN12 pushing over 1000hp here and he spent likely 50K+ on building the drivetrain. So exactly how much money do you have to blow on this build?

Have a look at David Neibert's setup. He's got a single turbo 347 setup pushing over 700 RWHP on one of his SCs - and that is a low 10 second car at 4200 pounds race weight (his best run so far is 10.04). Keep in mind it's a very different animal with a modular motor - RobertP has a Vortech'd 4.6 pushing 600+ RWHP and is in the 10s, EECDOC (Mike Siska) has an AED 4.6 also in the 10s.

A turbo modular mn12 bird has been done.
I saw it.
The turbo is mounted in front of the waterpump.
But the radiator is pushed foward, past the front (body frame radiator support thing) part.
This was a race only car. Stock engine bay sheet metal. It was a really clean set up.
I have no other information on this car.

Let's also not forget Bill's car. A rear mounted setup, but it was definitely a street car.

You can build a nice DD Bird for $6500.

I'm busy right now but I'm sure others can suggest a build plan for that budget.

Well with 6500$ why not start out small. If you want a turbo so badly. Build a turbo setup for your stock motor. Upgrade the injectors, pump, And some tuning and you can easily gain another reliable 100hp and 150+ ft lbs of torque. Use a single turbo with the room under the hood it is tight. Plumbing twins is a headache I have been thru the trial and errors. Battery in the trunk helps on space. Having a non-abs car gives more room. If you can live without AC you can gain quite a bit of room by ditching the AC plumbing. You can setup a single setup with a T4 style turbo that would give you the ability to swap out the single for a larger single should you build the engine and want more power latter. Its not going to be easy in a mn12. Or go with a blower as with a budget of 6500 you can easily buy a bolt on kit.

It's not but if it runs it can be force fed and if it breaks or your ready for more power you can have a built 2V dropped in to handle more boost. that is if you stay with a 4.6L 2V

Ok thanks. Ive been looking at early 2v's and Pi 2v's the only difference I see is the heads and intake. Am i missing something or is there block differences

The older (94/5) blocks don't have crossbolting on the 5th main cap, the cranks are heavier and supposedly the rings aren't as good as the 96+ incarnations(and from my experience, that's likely).

In terms of robustness, for all N/A modulars regardless of year, the weakest links are the rods and pistons.

NPI had flat top pistons and PI are slightly dished IIRC

NPIs aren't flat tops, they and PIs are dished. PIs are just dished more. The only factory modulars with real flat tops were the Navigator Mahle pistons Netkeym recently posted. Even regular 4.6 DOHC pistons use a 3cc dish

Oh ok my buddy said you can do a npi to Pi intake and head swap.? If so would it be worth buying his 02 heads andintake off his mustang

Depends on what he wants for them. It's really not any less costly than a full PI motor and a it's a helluva lot more time consuming.

Yes you can do an npi to pi head and intake swap. Its been done many times for many years. Also you can not just build a 1000hp motor and slap it in. You need to build the rest of the car too. Any plans for that aspect? As far as daily driving a 1000hp car, you will be perpetually broke and NOT driving every day. Not trying to burst your bubble but your goal of 1000hp for $6500 isnt going to happen. Try a more realistic goal. Ive got roughly $4000 into my car without paint, interior work and Im pulling the engine very soon.

Yes i realized this the npi to Pi was my original plan but then everyone started going on about engine swaps which is where i got the 1000 hp 5.4 idea from and I know you cant build it for 6500. Ill prolly stick to the npi to pi swap. He said 300 for everything

Well remember, you'll need to spend another $200 in gaskets and various other "while you're there" stuff in the end you can get an unopened PI motor for the same.

$300 is not bad for intake cams and heads. As long as its all in good shape. The PI swap will net you more power but is not a good option if your considering boost later down the road.

Matt, where the heck are you finding unopened PI motors for $500 bucks? A used one with 50-80k miles run over a grand. Atleast around here.
