Hi all, my 318ti is makeing lots of kocking sounds around the 3000rpm mark. think its my big end going engine has done 177.000 and was running well up to yesterday. Would like to know how easy it would be to drop bigger engine in. Had 325i or m3 in mind something with more power anyways, and would bigger brakes off m3 or m5 fit and e36 compact or will plates have to be made .Iv done engine swaps before so have some idea dropped a c02let in a nova. Any help and info would be massave help!! thanks ;)
