That's kind of a personal question to ask... Let's just say it's much less than you probably think.
I didn't own the car beforehand, so I need to factor that cost. If you already own the car, you can do the complete swap for about the same price as a good quality boost build for the f20c/f22. But with better reliability and much more torque... at least IMHO.
I know this swap may not be for everyone. Totally understand. That usually changes with a few seconds in the passenger seat. With LSx motors being so lightweight, the car's balance remains. The last project car weighed in at 70lbs over a stock s2000 without A/C and ABS. This one will probably be closer to 100lbs over since we are retaining both of those.
Thanks again for the positive comments. Hope to get a chance to meet a few of you at NOPI and other local shows.
