Can I set SPListItem Item.Id programatically

Question

I want to delete some list items and recreate them using a csv file. I can see if I delete the items and then recreate, Sharepoint adds it's own auto icrement int. what if I want a set of fixed values say only 1... 100 for 100 rows. Should the PS script work

$csv = Import-Csv $csvPath

# delete all the current rows - later this may be changed to update current)
Delete-SPListItems $siteUrl $listTitle

 #traverse each row 
foreach ($row in $csv)
{


    # now lets construct the new row we adding oops you must use the static names not the damnn names on the spreasheet.
    $newItem = $list.Items.Add();

    $newItem["ID"] =  [System.Convert]::ToInt32($row.Id) ;
