^I run silviav8.com and the guy who owns that car is on there.
Also the guy I bought my evo 9 engine from, sold it to put an ls1 in it.
I have had every part of an evo apart and I can tell you the build quality is very good. Stock they come with aluminum body panels, (10) forged aluminum suspension arms and brembo brakes. Interior is nice, don't expect lux, but to me lux is gay. I like gt3 type interior. At the end of the day an evo can be made to go around a track, up a hill, or down the strip quicker than most cars out there for not much money. Plus it has a full back seat and trunk. The only thing I hate about the evo is the looks, but I don't buy a performance car for anything more than performance.
I love the ls1 engine, sh1t I have a forum dedicated to putting it in a 240sx. Have had one in a fc, will have one in my s13 and if I had enough money I would have one in my s30.
I hate that "at the end of the day" thinking. Everyone sinking v8's, big money, time, and blood sweat and tears into there s30 must be crazy then. Cause at the end of the day, it's still a datsun.
