Could you please advise what's needed in order to upgrade a 90Hdi (September 2000, 43000miles) to a 110Hdi? Thanks.

I think an intercooler, i'm sure i read somewhere that the hdi 90 is so efficient they didn't give it an intercooler. so that intercooler must help, and probably a re-program, pretty sure they would use everything else electronically bar the programming on the ecu, maaaaybe bigger injectors, but doubtful again.

I would reckon it's boost pressure , ECU map and the intercooler. 20 BHP isn't alot really.

Did the HDI 110 have a different turbo to the 90?
DId it also have a different common rail setup?
Wasn't the clutch and gearbox different too?
What about bigger brakes?

What else.....?

You can chip it and get 110 BHP, but it will not BE a 110 IYSWIM.... as noted above, the 110 has (as least!):

Intercooler
Variable turbo
Almost certainly a different fuel map
Possibly larger injectors?
ML5 gearbox
The uprated hydraulic clutch
Uprated drive shafts
Larger brakes
Wider track
Bigger tyres

If you really want a 110, then best way is to buy one.... :lol:

Having just Plummed in a HDi 90 into a HDi 110 car, I can tell EXACTLY what I needed to make the 90 a 110

The turbos ARE different, not bigger, but have a different layout, and of course the inlet manifold IS different, so those two HAD to be swapped over...

The EGR valve on the exhaust manifold is in a different place, but thats not a problem when you swap the turbo swap the WHOLE LOT, you NEED to

You ALSO need the ECU from the 110 car, I already had this as it was a 110 car, SO on this, I ONLY had to change the turbo and inlet manifold and ABSOLUTLY NOTHING ELSE!

No NEED to touch the injectors! All the ECU does is OPEN them for a longer period to get more fuel - more fuel more power.

The injectors, pump etc etc ARE the same and cope with it all perfectly.

The car has now done 5k ALREADY, with out an ounce of a problem!

Dont think theres a Track different, just bigger tyres, brakes are different, drive shafts are the same.. and of course the MLT5 gearbox with hydraulic clutch, but the ordinary cable box can take the power upgrade easy, pleanty of boys with 306 HDi's which were ALL 90bhp ONLY have upgraded power with out a gearbox mod.

They have a much wider exhaust housing with another actuator for the VV section, generally looks much different to a standard turbo. Have to say that the turbo on my 110 doesn't look like a VVT.

There are some differences between the HDI 90 and 110 internal to the engines, for example, the crankshaft end thrust washers are a different part. The crank shaft thrust washers have to cope with the end thrust that the clutch generates, the bigger clutch in the 110 generates more end thrust so it needs bigger washers.

You can probably get away with using an HDI 90 engine and run it at 110 BHP in theory it'll not last as long as the 90 would but that's not to say it won't outlive the rest of the Xantia.....

They dont bugger about with that in the 306's im sure of that...

They might put a stronger clutch friction plate in, but they stick to the same box, so essentially, what ive done is the same as a BOOST box..

Time shall tell me I guess..

Revue Technique quotes different dwell (I think inlet cam).... also slightly bigger bearing areas around the crank journals.
