Differences between xsara vts & gti6 engines? - Matt-Rallye - 22-11-2016

Afternoon all,

I have an xsara VTS engine complete and ready to drop in my rallye, just wondering if anyone definitively knew the differences between the engines?

So far i have noticed the exhaust manifold is different

I will most likely change this too a gti6 manifold just for peace of mind.

Any other differences i should look for before i decide to fit it? I will be fitting it complete with the subframe & suspension thats already on it.

top arm if its from a phase2, injectors sensors etc also. fit the 306 stuff.

think the xsara engine loom is different ecu has 3 plugs not 1 like the 6
then id geuss that some of the engine sensors will be different similar to the 6 ph1/2/3 looms

Top arm? It is indeed from a late 54 plate xsara. When you say injector sensors does that mean i have to use the 306 injectors or is it a seperate sensor?

Is there any truth that xsara engines have more power? any internal difference?

Thanks cully Smile

i will be using a 306 loom (need to source one) and a 306 ecu but i dont know if they are coded or immobilised or just plug and play.

Luckily i have a complete spare 6 lump so all sensors etc can be swapped over.

ecu's are locked to the security control box which controls the Immo system
ecu's can be soft unlocked but it may be easyer to buy a perminent written unlocked ecu

I see, pretty similar setup to a 106 / saxo then. looks like i better get saving for an ecu etc now lol

Cheers dude Smile

yeah, basically get the full loom and ecu from a gti6 including the injectors and main fuelling sensors.

Thread revival time!

So brief run down im going to need to do the following to drop this motor into my red rallye shell:

- GTi6 / Rallye engine loom & unlocked ECU
- GTi6 / Rallye injectors & all sensors
- GTi6 / Rallye exhaust manifold

Anything else need changing over?

Just out of interest why can't i use the xsara injectors? In what way are they different to the GTi6 injectors?

RE: Differences between xsara vts & gti6 engines? - welshpug - 28-02-2017

different cc/min flow.

So why wouldn't they be suitable to use in my build?

They do work but best using 306 injectors,

No different in power at all, It's the modern management that makes them run better with twin Lambda's etc

because different amount of fuel injected for same pulse width.
