The Honda 2l K motor is very well developed and supported. I do not know if it is that much lighter than the Toyota/Yamaha motor. Some reports around this site quote either 15 pounds less or 20 pounds more....
Immitation is the best form of flattery and the Toyota motor is a bit of a copy and a response to the K20.
There are various 'formula' classes around the world where the K20 is spec'd. Honda tried to displace Ford in F2000, when Ford threatened to stop casting the old 2L blocks. Honda K motors are used in Midget racing. Look at 4piston, 400HP, naturally aspirated!! I would use that for a hell of a track car, although, personally, I like turbo motors.
So, cost-effective, reliable, powerful. The only disadvantage is that the Lotus did not come with it.
