Well DCB the 1500s is a type 3, notchback to be exact, factory dual carbs, domed pistons, hi po for VW at the time. Still gets 28mpg just like factory specs! Leaks like a sieve though...
You'll be happy to hear its been in the mid 90's this week and i have refused to run the A/C in the fiero, don't want to ruin my tank mpg! At 32.4 and have a quarter tank left.
