You also need the s13 compressor side outlet 3 bolt flange/pipe

You can only use the s13 oil feed pipe on a mk2 s12 mid 1986 onwards as the mk1's have a feed from around the other side near the oil filter

Ah right mine is a mk1.

Ill have to have a further llok at everything under bonnet then

Cheers guys

just to be odd, my c-reg auto mk1 had the oil feed on the turbo side of the block. Havn't a clue why but it was 100% the original engine

rpattafor's c reg had the feed on the left hand side too, lucky for me as i had the pig tail feed for it and mine split a few weeks ago.:)
