I hear it had a curb weight of 2700 lbs, which seems exceedingly light given that it ran over 10 seconds 0-60 in that Road and Track test. My car is over 3000 lbs, has 15 fewer horses, and matches that performance. Odd...
Engine wise, my vote would always go to the LS3 if given the option, but if it were to be the choice otherwise, there are plenty of decent options out there.
- The GM LSJ (205 BHP Supercharged 2.0L I4): A good choice that has been proven as a nice powerplant by the Ariel Atom, but it may not have the torque that DeLorean would want for the car. But for $5000, its a tough choice to ignore...
- The GM LNF (260 BHP DI Turbocharged 2.0L I4): Again, a proven choice in the Solstice GXP/Sky Red Line, but it may be too expensive and may not produce the kind of power delivery that DeLorean would want in their car. However, I'm uncertain on pricing, as GM hasn't made it a crate engine yet.
- The GM L32 (260 BHP Supercharged 3.8L V6): Its a well-worn design that has lasted nearly two decades, has proven itself as a powerful alternative to a V8, and can be matched with a wide variety of transmissions to put power to the ground. Problem is, GM already has a better alternative...
- The GM LY7 (250-275 BHP 3.6L V6): This would probably be the best choice to go with, given that it is a pretty well-designed V6 without too many mechanical problems, offers a pretty smooth and flat powerband, and works well with just about any transmission you throw at it.
...There is always the LS4 as well, but the size/power trade-off may not be worth it. Same can be said for the Northstar 4.6, which is probably too expensive anyway...
