leaving the 5.0 engine

well, because of gas prices, i have decided to getrid of my 5.0. i have been looking around and what i want to do is put a 2jz GTE motor. its the motor thats in the supra. it will be the first foxbody thunderbird with it that i know of.  its all cheap stuff too. i can get everything, puls install for under $5,000. im planning on running 500 to 600HP. i already have everything lined up. its going in halfway through summer. im sorry if some of you guys dont agree, but its about the gas. i will get way better gas mileage if i dont get into it too much.

And the $5K outlay will be offset by what? 

How long will it take you to recover that cost with the improved gas mileage?
$5K will buy 1250 gallons of gas at $4/gal.

+1 for Chuck..

Plus like a 500hp 6 cylinder is going to get very much more mileage than a 5.0 V8.

There is no such thing as an economical 500hp engine.

As Spock would say, "Illogical"

What MPG do you plan on getting out of the new motor?

1250 x MPG =

Miles you drive on averge a year/ above total =

and see what it come to and do you think youll save money? as for the power it sounds like a cheaper route but overall cost... gas prices isnt the best reason.

Even with the E303 cam,I'm getting about 25-26 mpg on the highway.

I'll say it now.....You'll go over $6,000....

Nothing ever goes perfect and in a one off project such as this prices tend to spiral upwards....

If your planning on jacking that supra motor to 600+ hp, you're not going to get much better milage than your 5.0. And it's not going to be as durable or reliable.

In his defense, stock Supra blocks will handle 1000+ HP.....Problem is as many have joked:  1000 HP 2JZ = 500 HP anything else.

Well I could care less what he stuffs in there, I was just trying to point out that claiming mileage is the reason for the swap is bogus as the money spent on the engine swap will net him 25K miles on an engine that gets 20mpg. 

He would have to drive that car for a LONG time for the saving from the supposed better mileage on the Supra engine will be realized. 

Even if gas prices continue to climb, unless this magicall engine gets 35-40 all the time (which it won't), it's just not cost-effective.

$5000 buys a hell of a nice high-MPG commuter bubble to drive everyday and still enjoy the 5.0 on weekends...

@OP:  Hate to burst your bubble but even a 300hp EVO motor gets just 19city 24hwy mpg....my 5.0 does better than that.

EDIT:  I agree with P71 as well.  5k could get you a very nice little 4cyl econo box that gets 30-40mpg.  You'd probably even have ~2k left over.  Your current idea just isnt practical.  You'd probably get worse gas mileage in the first place, and even IF it was an improvment, it'd be minimal and would never really pay for itself.

Not to dogpile too much, but there is another solution, a more economical solution that will meet your performance goals.  One that Ford figured out when they were making your car. 

And you won't even have to change hoods (hint hint).
