Hello

Just Registered.

My dad has given me is old 87 1.7d 5 speed T25 Battle bus.

He bought it in 1992 and used it untill 2001 when the engine gave up and has been a shed ever since :lol:


I am a mechanic and i want to change the engine to a 1.9d or td .

I need to find out a few things:

1. What engine code will fit the original mounts.
2. Depending on engine of choice will i need to get a wiring loom too.
3 Other mods that need doing e.g flywheel etc.

My dad wanted me to scarp it so he could have his garage back but i talked him into letting store it there till she is running. 8)

1.9 would be easier however if you want to go TD you will need the jx exhaust manifold, a turbo and exhaust check out brickyard aaz fitting guide

Hope this helps a bit
1Y will bolt straight onto the 1.7KY bell, as will the manifolds. Use the 1.7 flywheel and clutch DONT FORGET TO FIT A PILOT BEARING !!! I did not bother with the turbo thing as I wanted to keep it simple with less to go wrong. Only need the black fuel solenoid wire too. I have the four speed original box and she will cruise at 65mph but anything over that she screams her toots off. She gives 35mpg too. Sorry folks I am sure someone will enlighten me but I just dont get the turbo thing, it might get you off the mark a bit quicker and then ? ?
Good luck.

The other 1.9N/A diesel which bolts straight in is the AEF out of a Polo or Caddy etc. I've done that conversion, and we're chuffed to bits with it. I have posted a comprehensive guide to the swap on the brickyard. The installation is not a lot different to the 1Y. The advantage of both these engines is you can use the old gearbox.
