I was thinking about the heatshield model as mine is a turbo but then I did a search and saw what rebootit did with the fiberglass blanket from McMaster and that got me thinking. I have also looked at the hoodliner from Dynamat. Looks pretty good and is @$50. I have used Dynamat products before and it is really good stuff. Likely that is the way I will go. My concern with rebootit's install is the material is only rated to 180*F?? Seems a little low as the motor runs at about 180*F doesn't it? RT
