Beautiful Civic. It's hard to find rust free Civics of that vintage even in rust-free Vancouver. You must have put a lot of love and care into that car.
My parents would say that I was going to wash the paint off it.
I had the D16A6 engine in my 1988 Honda Civic Wagon RT4WD as well, although it was only tuned for 102 HP in 1988. Great engine.
IMHO the D16A6 had a different character than the later and much loved B16, B18 series engines. It was more spunky in the lower revs which made it a bit more fun around town. However, it didn't have that high reving character of the B series engines.
