Regarding the poll re ims install now or later. I have no wrenching skills but if it was me and in your situation I would get it done by an outfit that has done it before. LN Eng. recommended shops etc. Nobody likes an engine blowup and for myself I am older - see my handle, I have elected not to get ims done and if it blows up then I get an older Cayman. If I was tight for $$$ and young I would get the ims done. How can you afford an engine blowup in early life? That depends on how lucky you feel!
Trust this helps.
