Cars

You’re joking, right?
By the time you purchase the correct fuel system, wiring, ECM, guages, etc, etc, etc, you could simply BUY a very good Japanese vehicle. If you install a good engine into a Peugeot you are still stuck with the shoddy build quality of the unistructure, the poor grade materials of the body, demon possesed wiring, theoretical braking and drunken French engineering.
Ugh….

The peugeot 205 was a very popular model from 1983 to 1998 in europe. I own 3 now, and had 3 others in the past. Other people hit those 3 cars, and the body is not worth the repair money. I have done ALL my own mechanical work for 16 years on these cars, in addition to the 104,204,305,405.
Your diesel drive shafts are two different lengths and fit perfectly into the two front wheel bearings. This is your greatest concern, as I doubt you will find a japanese engine that accepts the Peugeot driveshaft ends exactly. This will mean changing the front wheels and suspension. Unless you are lucky enough to find a wheel bearing that fits Japanese driveshaft AND Peugeot steering knuckle. lots of luck.

Other major concerns (which can be overcome at great expense)are:
1. attaching the new exhaust system?
2. Motor mounts to fit UNDER the battery tray
3. Dash board guages are NOT a great concern, just find those few wires…easy on a 205.
4. replacing front wheels and suspension.
5. getting this approved by the MOT or european inspection station in your country. I assume you live in Europe as I do?

I suggest you buy a Japanese car that is 10 years old and drive it tomorrow. OR get a complete 205 1993 with a petrol engine. Available in 1litre, 1.1, 1.4, 1.6, 1.9gti. By now you can find the smaller ones for 500 euro. I bought one for 100 euro and did a head gasket repalcement. NICE car, yes it is a nice car. The brakes will stop on a dime. Brake problems are no problem if you really are technically knowlegeable and not some sour-grapes mechanic “wanna-be”.
