Engine conversions

[busta]

Evening all.
Anyone know if the 110bhp peugeot 1.6 16v HDi engine from the 206, 307, 407 etc will fit in a 106 1.5d? And if so how much work is involved? Ive never tackled an engine conversion before and i cant find much info on the web so any help, tips etc would be greatly appreciated.

Not familier with either engines but i am familier with the petrol peugeots.
Peugeot tends to use 2 types of engine which have there own type of mounting system, the 106 and 206 share the same type of mounts used on the TU series of petrol engines so fitting the motor shouldnt be a problem. What you will discover though is the HDi is a lot more complicated than the old type of diesel currently fitted so your problems are going to be mostly with the plumbing and wiring of the new unit.
Someone else may come along with a little more experiance in them.

The 106 diesels are 'TU' engines (TUD-3 for the 1.4 and TUD-5 for the 1.5). I guess they share the same engine mounts as the petrols so it would make sense that the 206 HDi engine is similar. I will have a look at my brothers 206 1.4HDi when i get a chance and see if it looks similar. But like you say, the wiring and the ecu may be the biggest hurdles. Hopefully somebody on here has a good idea of how people get over them.

Getting the engine in is the easy part, even if they have moved the engine mounts.

You need some way of interfacing the electronics, wiring loom should be available from someone on here.

But its getting systems like abs, steering etc that it is expecting to be able to talk to that is the real problem.

You may need a simulator box, which would be a one-off and not cheap to say the least.

Doesnt have ABS or power steering (arent they for girls anyway?) so theres no worries there. Might buy a shagged S1 106 to play about with until i get things sorted then swap the engine into my newer shinier 106. The ecu is still my biggest worry though. Its struck me that very few people know enough about them to help out and those that do charge alot.

Your's doesn't, but the car it will come from will have and the engine ECU expects them for certain information for the control systems.

e.g. Abs has wheel speed sensors and so calculates the vehicle speed for the Engine ECU (and others).

It will also probably be looking for the Body computer, which will more than likely be controlling the immobiliser.

Therefore you would need a simulator box to run the vehicle. Which is potentially ££££'s, but the question then is, is it worth it? As I doubt you'd be able to get an aftermarket ECU as Common rail diesels are quite bespoke in their operation, depending on the system fitted.

Its not impossible, just a challenge.
