Most famous car: 1987 Scoot, a mid engine "sports" car powered by a SOHC 8v 1.6 liter inline 4 making 98hp @ 5400 rpm and 113lb-ft @ 3500rpm. The car received many praises for it's handling ability and managed to beat out several more powerful cars during comparisons, though it probably received even more complaints about it's slow acceleration. Luckily the entire L series range of engines are drop ins, usually only requiring ECU tuning, the 2.0 from the 87-up Goblin GT became the most popular as the 140hp engine could get the Scoot to 60 in under 7 seconds.
