hi all just toying with the idea of do a cheap (ish) turbo conversion on 1.8 16v and came across a decompression spacer plate on ebay. i've had a bit of search but hadn't really found any info on people using them and how relible they have been? i take it i would hve to used two head gaskets one each side of the spacer plate? would longer bolts be needed? big location dowls? different torque setting on the head bolts?
my other idea is to have the std pistons manchined down? can this be done with con on the piston? as i spoke to a manchine shop and they said when pressing the pins out of used piston may damage the piston itself?
any info on manching used piston, swapping con rods or using decompreeion plate would be greatfull thanks allan
