I've worked with Nap, amazing project, ridiculously powerful. Very similar to what you are looking at. He has 15.5kwh and is getting 195km range max in mixed driving. The hawk is about 900lbs total. With an AC31 the 0-60 is something like <7 sec. It's a 4. something final drive ratio I think. That's with some seriously powerful cells running 38 in series. The specs are on the site.
150miles could be tricky, the Hawk is getting less than 80Wh/km, 128Wh/mile. You'll definitely be further ahead construction wise by starting with a Spyder though.
