Hi all, could any of you out there tell me how to go about changing the 1.8 diesel engine in the STDT, to a 1.9 from the 405/Xantia, and what suspension changes would need to be made? As I am not a mechanic, but would love to get this work done to my STDT. Also what is the point or difference in the rear beam from the 309 GTI?
I wouldn't bother fitting a 1.9TD from a Xantia; certainly not if you aren't a mechanic or working in the 'trade', as the cost would be astronomical, certainly many times the value of your standard STDT.
What you could do is fit an intercooler to your std 1.8 engine, along the lines described by someone previously, and recalibrate the diesel pump to pump in more fuel, which shouldn't be too expensive if you can find some one to do it for you.
I think the 1.9TD Xantia engine is significantly heavier than the std 1769cc TD Pug engine, so it will affect the balance of your car, making it heavier at the front end.
The thing about the std STDT was that it was so well set up by Peugeot. Believe me, once you start making serious modifications to a car such as changing engines, it becomes very expensive and you can actually lose the original character of the car. Any car remaining in a standard unmolested condition will always command a higher resale value, than one that has been substantially modified. Period.
I've specialised in 205s for 11 years. The best thing you can do is fit a 1.9 turbo diesel engine; it will not mess up any balance and it will be very cheap. Indeed, cheaper and easier than messing with the standard and very old 1.8 engines, you can pick up the 1.9 engines for approx 200 and fit in 2 days. How is that hard or expensive!?! Look on dieharddiesel.co.uk if you need any help or someone to convert your engine/intercooler/fuel pump setup. Also lots and lots of info at TDOCUK.com... Lots of tuning products/options to be added to the dieharddiesel.co.uk site very soon, so keep your eyes peeled.
FMIC. No problemo...
Also 1.9s are better on fuel than the 1.8s, so why wouldn't you!?
Does the whole engine fit straight in, or is there anything that needs to be modified to make the Xantia unit fit? ie manifold etc. Because the throttle cables will be different right, but making new ones is no problemo. :)
Any advice would be fab.
