RWD Duratec DOHC V6 again.

That flywheel wouldn't fit a duratec......its only 6 bolt flywheel.

You would need at least an sct tuner with a tune to ignore the lack of an auto trans. Ford performance specialists, Northeast Sho, ShoNut, and a few other people can tune the sct tuner.

Does that mean the Jag Duratec is different from the Ford Duratec or did they just use a generic picture?

Damn this is confusing. Makes me want to reconsider a SBC where everything fits everything.

I guess step #1 is to get the engine out see what it looks like. The closest LS 5 speed to me is 200 miles. I wonder if they would let me do a test fit if I took the engine up there. That might be worth the phone call.

I'm guessing they used a generic picture. The only difference in the jag duratec is the heads and cams (at least between the Taurus and X-type, not positive about the RWD stuff).

PCM, not ECU.

I'm 99% certain that one box controls both, here. So, yes, HAL is going to be unhappy.

They're the same car, minus some detail work. Sounds like a flywheel made for a triple disk racing clutch, which you can get centers for just about any input shaft you want. Too rich for my blood though!

Besides, once you start talking about racing gear, you don't really worry about trifles like what the OEM transmission was, you're just going to call up XTrac or whoever and tell them what you want.

But if you are going to do an external TCU, then why would you not use an aftermarket ECU? Out side of a few that may have VCT, these engines are really easy to do aftermarket things like MS- it's all common hardware and I/O. And the cars that have ETC can be replaced with a throttle that isn't- it's not as if millions of engines out there don't have throttle cabes with the V6.

For the manual posters, get the 6 or LS versions that start with a manual- those PCM's are just looking for a clutch switch and a neutral switch- other than that, there are no other inputs.

You've got me confused.....his 96-99 duratec 3L is not a fly by wire.

But the one in the Jag is, and maybe the one in the late 6's are as well. I wish I kept some data from a very late Freestyle that I tested....

My point is that there are a TON of cable choices if person A finds a Jag manual to start with. Some of motors do make more power than early ones- I probably would lean toward a later than 2001 engine, if I didn't have one lying around to start with...

In reply to alfadriver:

I'd start with what he has.....you can hone out the aluminum intake manifold and get a bit more power easily.

In reply to yamaha:

I think Noble will tell you theres a LOT to be had...

In reply to alfadriver:

Oh yes, all the duratecs are capable.

Toyman, FWIW, for $666 you can get the turbo manifolds that rossion(bought rights to the m400) uses on their Q1.

3.0L turbo V6...That should be fun under the hood of a FB RX-7.

I wonder if I can scrounge a set of Mazda valve covers.

Fixed.

the mazda valvecovers dont say mazda on them anywhere. atleast not in my tribute or my 6. but i actually run for fusion valve covers and coils on my 6 (purely a cosmetic decision) to take a fwd duratec and make rwd u need the rwd cooling stuff afaik. lots of plastic at the back side in the fwd version that isnt just an easy move. but the ports in the valley ect are all there on the engine. and tho never tested by the looks of it the escape intake manifold looks like it can simply be turned around. the fusion intake is the same as the 6 manifold but has a spot of a map sensor in the manifold.

I think you'd find a JE-ZE to be easier to work out the details, and all signs point to it also being ridiculously strong.

That's assuming it'll fit in an FB. I've seen it done in an FC, at least.

Minus the turbo, and make it the last RX7 (whatever it's called), and it's been done. I never got to drive it, and I don't know what became of it. The one installed in the Miata got a whole lot more play (and it was fun to drive).

Mazda did a V6 Miata Concept? According to this they used a 3.0 Duratec out of the Lincoln and the transmission and rear end out of a 3rd gen RX-7.

FTA: "...a one inch adapter ring to mate the engine and transmission..." So, custom, not a bolt-on.

In reply to Toyman01:

Not Mazda. The other company.

The Miata was done by people in my department. I actually had some leftover parts from the car for a long time under my desk, until I got sick of them and threw them away. And the trans was from an LS as well.

When I drove it, I told my wife that I wanted to do a V6 Alfa Spider for the next Challenge project- it was so fun to drive. The car was shown at a car show at the EPA. Big hit. Along with the Aston Martin DB7 and the Harley Hauler F150 we brought.

Back from the past.

I got the hood up on the wreck. It looks like the engine survived unscathed. The mass air sensor got smacked pretty good, but doesn't appear to be broken.

Naturally the intake is backwards, but it looks like it is symmetrical, so I should be able to turn it around. It's surprisingly large too. 24" long, 24" wide. Good thing the engine bay in a RX-7 is huge. It'll be a couple of weeks before I can get the thing out of the car and take some serious measurements.

prolly gonna have to replace that positive batt cable...

what? You can't ground the postive pole to the fuel rail?

Oopsie! I see 8 bolts....

I don't think you want a LS trans, it is a Getrag 221 and I read that it will not hold up to V8 torque. Which means it's weak.

No spray No boost No hammering it

BINGO! What is the part ID on this baby? Is this the
ZF502

Or was the Contour the lower flywheel? Much heavier and a stepped design are pressure plates and discs available that will hold 250HP for it?

You don't want an LS flywheel because it is a dual mass unit.
