I think if you really want to do a turbo on this, it's going to need some sort of I4. The 3.8s are packed in there REALLY tight. I think adding a turbo would make the heat problem worse with the 3.8. You'd be replacing head gaskets weekly!

The MTX-5 transmission that was used in the Tauruses might be strong enough for the Windstar. There've been one or two people that managed to mate one up to their 3.0 Vulcan Taurus. I wouldn't bank on a MTX-75 (used in the smaller cars) holding up for too long at all.

What about a small diesel? Find a wrecked TDI or something?

Even running low boost not all OEM ECU will be able to compensate. It will depend on the engine and the capabilities of the ECU. Either way you will need at least a wideband, data logging software and software to retrieve, modify and upload tunes. You could invest in an aftermarket ECU like FAST or megasquirt which would make it easier to tune but you would have that additional cost.


I am not trying to beat you down... I have researched heavily in putting a turbo on my 4L Jeep engine.... I found out that there are a lot of hidden costs and problems that would have to be solved. After I added up the costs for the estimate...it was north of the $5,000 mark. For that kind of money I could do a 4bt engine swap and have more power and economy than a turbo 4L.

There's a video of a turbo 4.0 TJ ... it picks up the left front tire it has so much torque! I've never felt any of our 4.0s were underpowered, though. Fuel economy ... it's a tractor engine from the 60s, powering something with no consideration to aerodynamics.
