Paul Carrera Posted 6February Report Share Posted 6February Just trying to ascertain the differences between the two engines I have purchased a 1983 euro s 300hp engine as a spare for my 84 S2 310hp engine and apart from the intake and fuel system am wondering what the differences are if any, mainly regarding the pistons and heads. I know the cams are different and the 84 has a bit higher compression. Trying to work out if it is worth updating pistons, heads and cams on the spare engine and if I would really notice any difference. I am planing on putting in the 83 engine using the 84 intake and fuel system and then reconditioning the 84. I am aware I will have to make provision for the flywheel sensor by drilling. Also thinking of just swapping over the cams as that's pretty quick and easy to do. Thanks Quote Link to comment Share on other sites More sharing options...
