what are the differences with these engines? ive got a mk2 and puttin a mk1 engine in

nothing much. Just different oil feed line to the turbo.

If you can get the oil line with it that would help you alot.......

the ancillary pullies are different too

mk1 and 1.5 have got mechanical valve system mk2 hydraulic ones, right?

wrong Alundra.

As dr_silvia has just pointed out the pullies are different including the bottom pully but they are all interchangable

if your putting a mk2 head on a mk1 bottom, then you should have no probs, as all the differences i.e pullys and oil feed pipe are all on the bottom end, tis just you have to keep the mk1 turbo pipes.

I bought a mk2 head from canada it has got hydrolic valves system retainer don't know the right word, sorry):

What i had on my car mk1.5 -mk2 lift, no rev limiter- with mecanical clearance system:

The pulleys are the same.

What do you think about that?

thats not standard mk1 or mk2. I think thats been fitted at a later date or at the very least it was not available in the uk.

Maybe 30psi would know about it,i havnt seen it before.
