hi can anybody tell me the difference in engine numbers i have a petrol 1900 df engine and want to put dg bottom end in my t 25 and use all my df top end auxsilerys would their be a problem cheers billy bob

yes you can do that, dimensionally they are the same and it just bolts straight in, you won't get the extra power of the DG without changing carb to the pierburg 2e3 , inlet manufold and dizzy.

The heads are different and therefore the inlet manifold is different as are some of the water pipeage..... But yes berthing else is interchangeable

Thanks for that mate, so can I still use the old carb and dizzy, I'm not really interested in the extra power, just will it work sufficiently? Cheers

you can bolt a DF manufold on a DG, yes it will work.

For your future ease and in the interests of reliability you should consider getting a DG manifold and water pipes so you can get parts easier if you need them

Sorry if its a dull question - What is the difference between a DF & a DG (& what do they stand for ?)

The DF is 60hp the DG is 78hp, the DF and DG are engine number codes .

your engine has a serial number the first two letters being the engine code, unless it was rebuilt by VW then looks like the second pic

Looks like my engine (that went bang was a VW rebuilt engine (funny symbol followed by 265).

Its a 2.1 (or at least that's what I believe it is !), - is there any way of telling from the above number exactly what engine it is / was ?

Just double checking before getting hold of a s/h engine case (as the conrod went through the old one - have had 8 or 9 years out of it (I had it s/h so don't know when the rebuild was done.

Cheers

the late 2.1 and 1.9 case is the same, if it has two oil pressure switches then thats a late case and what you need.
if it has one oil pressure switch thats an early case and won't be a 2.1

.... unless somebody modified the case of course, somebody on here has done that

a definate way to tell is the top bolt is m10 on a late case


and smaller on an early case



if you want to know what pistons it has then a USB endoscope down the llug hole will tell you

DG at back, DJ left, MV right

Thanks Itchy Feet
