you know VF1 you are correct why spend 80, 90 k on a fake anything, maybe it has more to do with something that someone likes or loves to do, I can tell 100,000% if I knew I would have near what I have in my 640 build I would have bought a real OEM car and more so to have the car now to enjoy, I built this car with my son to do a project with him before he leaves for college, the biggest issue I see is there is allot of JUNK out there, allot of these guys see a high price on an OEM part and they start seeing dollar signs and then do a poor job of replicating it and then wonder why people won't buy. When you start talking about 700 HP there is allot more issues then just getting that HP of a motor, then you have to think about trans axle, half shafts, clutches that can handle the torque not the HP so obtaining that type of performance is probably going to cost more then the project in general, 500 to 575 is more realistic and then your are starting to stretch it a bit, by no means do I want to discourage anyones dream to obtain the best that can be done but I do agree it comes to a point of getting out of hand.
