Anybody know what a complete Z7U engine from a Renault 25 Turbo would go for these days? I tracked one down and i need to get some prices settled.

thanks

Congrats. What shape is it in?


I see the water pump isn't in the usual spot in the Valley, what can you tell us about that?

Only that this particular engine came from a Renault 25, was taken out and used in some sort of kitcar and ended up as an educational piece at an automotive high school.
That where i got it from and found pure by chance on a big national classifieds website.

The waterpump is something not original indeed.
Does not have drive pulley at all and seems flow was created externally.

Engine itself looks not too bad but i do need to do a complete stripdown do inspect the state it. But my plans are to use the turbo setup and the inlet manifold obviously

Waterpump was altered by PO to run an external pump.

Egine itself is in good shape. VOD seems solid.
Turbo is histoy and one bolt holding the inlet manifold snapped unfortunately.

One tiny setback.
Engine block was repaired some time with epoxy to fix a crack of some sort. A crack that leaks coolant.
Hopefully some weld can be done here.https://uploads.tapatalk-cdn.com/20190311/368d926f774c7bd43f7d4db8f9c73738.jpg

Looks like a great project. I really like the simplicity of carberated RPVs.

Carbureted? Looks like EFI to me...

Indeed.. no carbs here.
Already found another Z7U inlet manifold for € 150 for a fellow owner.

I thought these things where scares?

Much more scarce in the United States, where most DeLoreans are.

After discovering a coolant leak flooding the VOD in my D i tore down everything to clean i all up.
Doing so made me realize it is utter nonsense to swap this engine for one that i really do not know it's history nor if it ever was abused.
My original PRV is still so reliable and clean from the inside it would be madness.

So i cleaned everthing up and gave it a repaint like i did the first time 12 years ago.
Cat was defective so off with that and caused me to create a custom exhaust all together.

One thing that will still be on the To-Do list is to get it converted to EFI
So all that will be left from the 2.5 Renault engine is the inlet manifold
