Ok, the K20 motors are quite the die hard motors, reliable, efficient, and tuneable. Found in most Hondas(and some Acuras), it's the workhorse of the generic Honda platforms.
As for the new SI, they are actually turning out quite the numbers in the performance category (but still not as good as the turbo balts, lo)
When it comes to remote car starters, and the "two-way transmitters"* the Titan system of remote starters is probably the best way to go here, with the all new "text start" system, which allows you to start your car from anywhere you get a signal!!!!
It's al your choice really.
