Aside from the fact that I would never buy anything from Eastern Aerospace...
The life of a NA aspirated engine is decreased GREATLY by adding a turbo kit. For example, those Civic's with bolt-on turbos and superchargers have a very little life to them. Sure there are those exceptions, but on the majority they are not "long-lasting, reliable Japanese automobiles"
Also, the internals on Turbocharged engines are different than the internals on a NA engine, they're beefed up for the more power and higher pressure that they need to withstand.
If your car's engine is fine, runs really well, and you do sevice it regularly, why tamper with it? Man, I like the way your car looks, with the body kit and underglow, it looks good, but if you really want more power, you can always go for a Turbocharged model, T-5, T-5R, R... it's up to you! Good Luck
