pistons

[vwrallycar]

On ebay at the moment is a set of pistons, they suit the 2 litre 16v 1990 to 93, can anyone tell me if they will work in a 1.8 8v? i know the block needs boring, but are 16v engines use the same pistons etc as the 8v?

They'll "fit" but you'll have waaaay too much compression and also (from what i've been told) the pistons will need to be fly cut to give clearance for the valves.

Waste of time.. Just get the -right- 8v pistons.

mm. i have this exact issue with my car.. the 16v has its combustion chamber in the head, where as the 8v has a dish in its pistons.

a lot of machine work (read: $) unless you're into that sorta thing ( preen ) to make these suitable for an 8v.

edit: however, a 16v(abf) with these pistons, a bit of head work and some cams would fly!
