It was an 80, but on the side it said 4500.
4500 EFI is common on FZJs in most non-US markets, indicative of the 1FZ-FE.
Can buy for ~$20 on eBay and is fitting on any FZJ80, if flair is your thing.

Edited: before corrected.
4500 Twin Cam is typical 1FZ-F
4500 EFI typical 1FZ-FE
Think some had the 24V badge, too, but dunno where or if a 7X, 80, 100 thing.
