whats need to conver t a hdi 90 to 110

Short answer is too much to make it worthwhile.
Either swap the car for a 110/2.2 or pay for a remap to give you about 125 bhp for something like £80

Not for me someone posed the question regarding the car I'm breaking

I wouldn't have thought that fitting the intercooler would be much of a problem if you have a donor car for the hoses etc. I appreciate that the fuel delivery will need to be increased could that not be programmed - just curious.

90's have a mechanical wastegate, 110's are controlled by the ecu & have a MAP sensor & wiring, so ecu firmware is different....
The ecu's matched to the BSI and ignition transponder, so not easy to swap that over
Later 90's have Siemens fuel system, no lift pump and a completely different fuel pressure regulator set-up

You might be a bit out of touch.

You're right.

Right thanks, didn't realise that.

Yes all above is correct but,
The 90's can be remapped to 150bhp,
The intercooler is easy enough to retro fit,

Please desist in misleading members with your inaccurate information

Whilst I'm at it can you get me a price for a new back box? you seem cheaper than most online places I've found, thanks.

Certainly, Cistern or Vulva?

ps. Anyone find a bosal for the estate

Easy conversion if its just the intercooler, you will need all the 110 pipework and the elbow on the intake manifold and away you go. To take advantage of the charge cooler, you will need a remap and you can make pretty much the same power as the 110. You will have to manually increase the boost on the 90 as it is controlled by a mechanical wastegate (0.9bar factory I think), so the rubber vacuum hose will have to be cut and a bleed valve added if you want to take it past ~125hp. Be aware though that the HDi 90 crank is different to the 110 crank (which is burnished) and can therefore take less abuse. As such, with a 90 vs 110 mapped to the same power the 90 will wear faster. My 110 is currently running 1.4bar boost with a max fuel delivery of 80mm^3/str between 2300rpm-3200rpm. This gives an estimated 330nm/150hp with a much nicer torque curve than standard, and is +80nm and +40hp. We all know Pug likes to undertune engines and these are bulletproof so gains like this are no problem as long as good maintenance is carried out on the vehicle and the crucial components (most notably injectors, dmf, turbo and bottom end) are in good order.

I've done a lot of research into the DW10 engine so if you have any questions, shoot me a PM.

Best Regards,

Thanks for that Ben, I have run four of these engines and have had no problems until my wife's lost power below 2000 rpm which I think is a turbo control issue, suddenly comes to life at 2000 rpm. I have yet to check all the vacuum hoses. We have been driving it like this for sometime and generally its OK unless you are suddenly confronted with a steep hill. I have swapped the MAF with mine and it makes no difference.

The power output of the 110 hp suits me fine so I'm no bothered about improving it, 50 years ago maybe I still do a fair mileage but mostly in the slow lane. Mind you I drove a 206 90HP the other day and that took off, reminded me of the BX turbo - and about as refined.

There's not only power to be gained from a map, the additional fuel economy and refinement brought from the broader, more usable torque curve brings the car to life. As much as the standard output map may suit you, I know you'd be much happier with it mapped. Not to mention the map will eventually pay for itself in fuel savings.
