Hypothetical question - replacement engine head

[Portent 0]

Hypothetical question... if I were to source an alternate head then how much would it cost (ballpark figure in hours or cost) to get a garage to swap it over. i.e. drive in, hand the keys over and drive out. Nothing wrong with mine but I can get hold of a refurbished head for the future.

 

My car has already had chains done and new cams but the previous owner didn't do any other work at the time so it seems a sensible precaution.

 

To clarify... just the labour cost, not the cost of the head itself.

you been in cotact with VEGE then??

Should only take an experienced VR6 expert 4-5 hours, but I'd budget a day for contingency. So 7 x £XX per hour.

^^ Thanks for the above.

 

Yes VEGE. Does anyone know the difference between:

 

AAA code 1993 - 1997 Schrick variant

AAA code 1992 - 1993 distributor variant

 

I assume the 1993 - 1997 would be right for my coilpack 1994 VR. But why does it refer to Schrick?

[Kevin Bacon 5]

God knows.

 

The only difference with the 12V heads is the later ones (OBD2) had a revised internal casting around the chain area and for EU3 emission vehicles, EGR ports added.

 

The dizzy and coilpack hardware is all in the cam wheels / cover plates etc, not the head itself.

Would an OBD2 head fit on an OBD1 bottom end? Or would that involve additonal changes too? I'm just wondering if I get the wrong one then will it be a problem?

Ok I have a little more detail on the 1993-1997 one:

 

"2.8i schrick 1993 1997 motronic hydraulic lifters, tuned version without hole in distributor cover, with air injection reactor"

 

I'm starting to doubt that's the right one and I don't know enough to guess whether the 1992-1993 variant will work either. Any thoughts would be much appreciated but it may well be a case of flip a coin and take pot luck.

A little googling has shown that there is a slight difference between dizzy and coilpack heads; the coilpack heads have an air injector hole (no idea what that does). So potentially neither type will be a straight swap. I'm sure it could be made to fit but not sure the effort.

i thought the heads were all the same for all vr's, just that the dizzys have a different end plate for the dizzy and the pick ups on the dizzy cams??

 

i hope so anyway as my head should be here anyday.

So you went for the dizzy head? If so then I'd welcome your feedback once you've received it and had a look over it. VEGE confirmed that "a dizzy version will fit a coilpack corrado but it's not a straight fit".

put it this way the engine i fitted (the re-built one) was a dizzy, i just changed it over to a coilpack and its worked fine.
