Changing a mates 97 16v to a v6 due to engine problems, I have all the parts needed to change his car to a v6,

Engine
manual box (car already a manual)
Exhaust system with heatshields.
Engine and Injection loom
Cooling system
V6 dash clocks and MID

We are not bothered about traction control so is it right to assume that the abs setup can remain the same?

Will we need to change the fuel pump or are they rated the same pressure?

anything else that we havent thought of? (apart from going and buying a miggy thats already a V6)

seeing as all the bits are here and its not costing anything apart from time, we think its worthwhile.

cheers

i think dont quote me on it but from memory according to my trusty tradeclub book that the p/n for a v6 fuelpump is the same as a 4pot dont quote me on it though! will check the book l8a

[Mr Skrunts]

ECU and other Electrics.

Maybe odd bits of plumbing for Air intake and water systems

[vauxfan2k]

doh! forgot to add that we have the ecu with the engine loom, ecu has matching chips and reader for barell. also have the prop shaft and v6 diff if needed to keep ratio right.

all water hoses etc are here also.

[markey mark]

go for it matety !! should only take a day or two !!  

[vauxnut]

will front dampers ect need changing due to diff in engine weight.

[ngrainqey]

dont think dampers need to be changed, what about the power steering reservoir?
also the diffs arnt the same between the 2.0 and 2.5 but on the 2.5 auto they use the same as the 2.0 auto(3.9 instead of 3.7)-they changed some of the final ratios from 98 onwards

[RobG]

V6 and most 2.0ltr models have 296mm front discs. Some of the earlier 2.0 had 286mm. Only 10mm but more braking area

might be cheaper/easier to just get a completely fresh car!!

he apparently has all the bits needed danny.
its not too bad on the later omegas but on mine it was a pain in the arse so i gave it up when i got rather hacked off that it wouldnt crank due to immobiliser box on the early ones with immobilisers that i couldnt find nestled up near the airbag

totally forgot to update this thread, its all done and running sweet, you would never know it wasnt a v6 from factory. did it over 3 days. changing manifold gaskets and all the hard to get at stuff while the engine was out.

We used the 2.0 shocks but the v6 springs as the 2.0 shocks were in better shape.

We also used the v6 diff to keep the ratios right. even changed the MID to keep the fuel consumption right.

was nicely suprised to see that there was no eml light at first start. just shows taking some time makes things easier.

If I had to do this again instead of just going and buying another motor with new problems i wouldnt hesitate.

cheers

the mid should display correct fuel consumption regardless as it goes on the average mpg and how much fuel you have in the tank

I thought they were programmed via tech 2, IE a v6 is going to use more fuel than a 2.0, and a 2.0 is going to use more fuel than a 2.5td etc, so it needs to know what it is to display the correct information. :-?

It all depends on how vx's ecu to MID protocols work I guess, which I dont have a clue!

Correct. The MID gets a signal from the engine ECU based on injector duration, and it needs to turn this into gallons consumed, so needs to be configured for the engine, amongst other variables (using a tech 2, as stated).

Aye thats what I thought, Just a quicky... Would that mean changing the fuel rail pressure would result in the MID displaying incorrect information then? Ie, higher pressure, the injectors would be open for a shorter duration, and thus the MID would think that the cars using less fuel, and therefor show higher MPG / Range etc?  :-?
