Title: Different head
Post by: larky75 on 12 August 2009, 08:13
I want to give my Mk1 a bit more pep and was wondering if this head will fit the DX engine, I'm think this is the digifant version. Any help would be much appreciated

it'll fit, you'll need to swap the injector inserts for k-jet ones, depending on the age of your head the old ones may not fit, so you'll have to source later ones. 16v items should fit

is DX not a solid tappet block, threfor missing the oil return gallery for a hydralic tappet head ?

i was under the impression the blocks were the same regardless of solid or hydro?  if not then yeah the dx is probably a solid lifter one unless its very late

i thought when vw changed to hydralic tappets they added an extra return gallery the sump.  i know a solid lifter head can go on a hydralic tappet block  but not sure about the other way round,  proably will just on of the return pots may need plugging,  just somethign that may be worth checking

when you say "bore out the head" are you on about polish and porting the head or increasing the cylinder capacity of the block??

a 1.8 head will go straight onto a 2.0 block.  you do not have to change anything,    it is however adviasable to place the 2.0 gasket over the 1.8 head and trim the edge of the combustion chamber out to the gasket.

some enigne need it some don't  but there is potential for  the edge of upto .75mm sticking out,  managable but not optimal

What advantages would a  mk2 1.8 head with ultimate road cam and pully have over a standard 2.0 agg head. :smiley:
Title: Re: Different head
Post by: rubjonny on 25 September 2009, 09:16
mainly the ability to run mk2 managment, sicne the inlet manifold fitment is completly different.  obviously the cam will make a difference, but afaik it'll fit the mk3 head as well?
