Hey Guys, So I have a 93 Honda Civic Sedan and Im looking to achieve some modern age luxury car silence out of this thing. Now, you might think that isnt too hard but I have swapped out the standard 1.6 engine for a new JDM Type R 2.0 liter engine with a fat exhaust. I've got solid engine mounts that send vibrations throughout the car to make matters much worse. Now, Ive gone with good ol' Second Skin for my brand of choice and getting it locally via the Second Skin representation since I am from South Africa. Now, Ive plastered Damplifier Pro throughout the interior of the vehicle (1 layer, with a 2nd layer in the boot area and outter layer of the doors) (but have nothing on the roof). Ive also got a layer of Luxury Liner Pro from front to back (as far high as the dash allows me to as far back as and including the boot area). Now, when Im cruising around at 2,000 rpm (which is hardly the case), its acceptably quiet - however; go past that and you have to start screaming at eachother in the car (eg: cruising at 100kph @ about 3.4k RPM). Heat is also a bit of an issue, sunny SA gets 30-40 degree celsius springs/summers and my car is black to top things off! Whats next to achieve my goal? (below some steps of things Im thinking of doing, though Im all ears to opinions / thoughts / suggestions!) - Apply Damplifier Pro to the roof to help the noise and heat? - Apply Heat Wave Pro to the roof to help with the heat? - Im pretty sure I can fit some Luxury Liner Pro in the doors without interfering with "internals"; just a bit worried about it actually staying stuck with normal contact adhesive - Apply Overkill Pro inbetween the door panels and the doors (Im hoping it can actually compress that much or should I rather go with regular Overkill)? - Apply Spectrum to the engine bay? - Apply Spectrum to the underbody of the car? - Apply Thermal Block to the firewall and exhaust tunnel? Thats about all I can think about or am I missing something? Am I asking too much and just wasting my time with these goals?
