My 2200 EFI seemed alot faster than 15 seconds, I would say it was 12-14 seconds. I could easily get rear wheel spin in the rain on pavement unitentionally.
86 Mitsubishi mighty max 2.6(same motor as 2.6 in 87 b2600) spins way to much in the rain. Pos open diff, doesn't drift at all but will spin the inside tire through 3rd gear in the rain. Haha
