RHD V6 Activa numbers go up by 1

[citrov6]

thats a shame. though i don't think it matters too much since that bosch ecu is very good at adapting it seems to make it optimum whatever is thrown at it.

megasquirt would be more useful to someone changing the spec a lot and with a box that can keep the revs high.

the autobox antagonises itself, it needs torque because it hasn't the gears for power, yet the documentation says its limited in its capacity for torque

fortunately the gears are so long it sucks up the torque before it hits anything after final drive. mainly just the clutch packs that are the problem i guess?

having said all this i'm quite happy with mine for what it is it gives reasonable mpg and acceleration which is why i have been able to use it as a daily for so long


just had a look up of venturi their 300bhp one was a twin turbo 3.0 v6, i have heard of a 300bhp clio v6 without turbo's i would think that is probably 8000rpm redline or more

also remember seeing a throttle body kit for one, now that would be fun and worthy of megasquirt i think

Those and the Torque converter. I know when the Americans want to shove more power through a FWD car, with an auto "transaxle" the first thing they change is the torque converter. Least that seems to be all I read on the forums

[citrov6]

torque converter wont be a weak spot, i think they do that for shifting the stall.

yea easy to get caught up reading whats available on the other sides of car culture

As an aside to the above.

When they have serious horsepower, in a rear wheel drive car, and they go racing the Americans stick a Lenco in it, here's a quote from their web site, about their range of products.

"The LENCO transmission family
Seven different designs engineered to harness up to 2500 HP!"

That's a lot of HP!

Superchips do a chip for the V6, but it only yields an extra 10bhp. No information about the torque is provided, so it's probably a rare mod. It's conceivable it could improve the drivability though, without busting the autobox.

so they do. that bluefin looks interesting, could be used to upload maps, pity its not available for citroen.

[admiral51]

In addition comparing part numbers is a waste of time because the ECU's are supplied blank from Citroën and programmed on the car via a Lexia.

Although it's a Bosch MP7.0, once again being Citroen/Peugeot, it runs it's own unique protocol when communicating with the diagnostic socket which is incompatible with any known ELM-based OBDII reader. We're back to using a Lexia or a Lexia to read the thing. Unfortunately, the Lexia offers no scope for looking at the maps inside the ECU or changing them

Technology confuses me but if the above is true then if it can have the maps put on by a Lexia then surely the Lexia must be able to read it to confirm that what its put on is correct or am i going off in a totally different direction

No, sadly Colin, unfortunately all the Lexia can do is upload updated ECU software to the ECU. You can't actually see into the software or what is in the update

[citrov6]

No, sadly Colin, unfortunately all the Lexia can do is upload updated ECU software to the ECU. You can't actually see into the software or what is in the update

hmm so theoretically if you had software to change a file you could upload it via lexia, but you would need the file in the first place, or use their update file to work on. although i think those cd's on ebay with software might have the tuning software. a confusing but interesting world this software thing

Bonsoir a tous

I reckon if one paid a professional (experienced) to carry out a full conversion the bill could easily be close to £6k and possibly a lot more.

A diy job would be less expensive but even if one bought a 406 engine/box lump for say £500 (or a complete V6 Exclusive) and add new clutch, water pump, timing belt, pulley, tensioner etc, rear engine mount, exhaust system, 4 filters, 6 plugs plus incidentals the bill rapidly rises.

Upgrading the spec to include heated electric leather, one touch all round ew, indexable mirror complicates life (looms, relays etc) and adds to the bill. Include engine and gearbox oil, coolant, air con recharge, new drive belts and on....what if discs/pads/tyres are needed too, maybe heater matrix and expansion tank?

I bought a very late Activa and a low mileage (29k) donor V6 Exclusive. I also bought a gearbox, flywheel and various 406 V6 bits from Adrian up in Derbyshire.

I just can't see how something like this could be done for a grand though I'd be happy to be shown the errors in my prognostication...

Anyone go to the 4th Euro Citro at Le Mans? Oh what wonderful cars, the French Activa Club was well represented.

Knowing what is involved, I agree. How much would BL Autos charge?

That might just cover it on a full DIY basis. It's amazing how quickly the money gets swallowed up though. I've spent close to that just sorting out my V6 and that, except the hydraulic regulator rebuild, was just on parts and doing all the work myself.

The point is that for a pro to do it, there is many, many hours of work and that's where the cost is.

It is high time someone did a DIY V6 Activa. I'd love to but lack room. How about you Andrew?

[Citroenmad]

A 2.0 Turbo estate was converted a few years back to manual V6 Exclusive. I had the privilege of owning that car for a year or so. The current owner has made a number of mods to the car, the latest and for me the most interesting, is a higher 5th gear ratio giving much lower revs than previously.

The S1 Estate with the S2 front and a V6 manual that was on the Citroenian stand at last years classic cars show NEC?

Very nice car if so 8)

[andmcit]

Out of interest, as this thought once crossed my mind, should a V6 lump be
fitted into an Activa shell what clutch mechanism get's fitted; this is assuming
a manual box is preferred and a suitable clutch kit is sourced?

Is the current master/slave cylinder set up on the UK Activa/HDi and 2.1TD
going to work with a manual box off say a V6 406 Coupe? Not all of the LHD
v6 system will be compatible and this only leaves the range offered in the UK
which as far as I know doesn't offer a complete v6 set up for manual.

One other thing is the set up of the ECU engine management for the
autobox - won't this be different for a manual box where slightly different
characteristics will alter the efficiency etc or this so marginal not to care?
Course if you retained the autobox on the V6 engine there shouldn't
(in theory!!) be any stumbling blocks but then if you're going this far down
the road of reinventing everything yoiu may as well has the optimum spec?

I believe so but why put an S2 front onto an S1 car

Hi Jim

You are right about the hours involved, especially if something is damaged/rusted in/previously bodged - all this would be in addition to any estimate.

There are so many variables when looking at the cost of a conversion - I think, given that Citroens are their living, that BL Autos may be willing to quote on an individual basis but even "simply" (it's not!) an engine/box swap would cost serious sums.

One really has to want a RHD V6 Activa to pay someone to do it. Turning the dream into reality requires a sensible budget and contingency, an understanding insurer and a real desire to make it happen. How many people are willing to spend wedges of hard earned cash on 10+ year old Xantias?

I'd wanted one ever since Barry Lowdell (BL) took me for a drive in the car his son Robert had just converted back in 2000. It took me seven years to get there!
