how can increase power in a 2k engine
In a 1979, I don't know what you mean by '2k' but the Starlet came with either 1.0 or 1.3L.... a 37 year old car, little to nothing. Even if there was a way, all you will do is blow out the rest of the drive train.
That's the 2K hamster version don't ya know. HaHa...shrug.
