so look for the intake mani thing, clear tails, steering wheel, gauge cluster, front and back bumpers to know its a 90-91.

what are the specs on 90-91s? hp, tq, weight, etc?

 

An easy way to tell is the front bumper, on the 90-91 the center is like the car is frowning and the 91-92 looks like the car is smiling. And look at the ehxaust manifold, if there is an oxygen sensor on the front of it under the hood then its 90-91 as the 92-93 only have one oxygen sensor near the cat. I have both years in my collection and I checked them out side by side.

 

and what parts could go on a 91 civic hatchback? motor, suspention, brakes, interior?

 

Try asking in the Civic forums. They'd know better than us in the Teg forum...
