thanks for the info,have to get it running,they tell me after they put a timing belt in it it started knocking,probably they were off a tooth on the timing,,i really want to keep it 2.3,has an auto in it probably three speed?c4? ,,some say these cars were lightweight sure don't look it,but it still a good looking car,no rust,if it turns out to a bad rod,which i really doubt unless they ran it with no oil,those 2.3s rarely die,,,i really don't know much on turbos other than they are great for power and generated quite of bit of heat,,,thanks again
