Title: Differences between JR and CY, JX, KY diesel engines
Post by: [email protected] on November 03, 2020, 01:18:07 am

Does anybody know what are the differences between a JR engine and CS, JX, KY engines? Mostly in terms of internal tolerances for rebuilding. Or any JR manual?

Well the KY block was used for the 1.7 engine.
 For a vanagon or something.
 The pistons will work with 1.6 block/crank/rods pistons.
 But you'll have to bore it to around 80mm.

 Did you mean CY?
 I heard those were in the Rabbit 1.6 turbo diesels.

CS is the non-turbo 1.6 Vanagon engine code. 

JR is 1.6TD Rabbit/Golf (Same as MF)

JX is 1.6TD Vanagon.

KY is 1.7 non-turbo Vanagon. 

If your engine is JR engine code, then I would recommend getting the Mk1 Bentley.  Make sure it goes through '84.
