I'm not sure where he found this, but it looks like production plan numbers.
Show and go
The Mk.4 NA Supra manual is surprisingly fast for its time. Remember these were the times when entry-level Aston Martins and Ferraris barely go under 6s in 0-100 km/h.
Being so light I think even with the 2GR-FSE the Mk.5 Supra can still be very good, definitely better than having a 2.0T I4...and the 2GR-FSE can be had with a manual.
