Hey I have an 87 olds firenza hatchback 2.0 3spd auto and was wondeign what headers form other j-bodys are intechangable with my engine
Headers?? only one header, its a 4 banger

... sorry i just hate it when pople use the plural when theres only one header.
sorry i dotn have any construtive information to give, all i can think of is maybe the sunbird 2.0.
------------------------------------------------------------------------
only place i could think of would be mantapart.com, otherwise the 2.2 header will not work on the 2.0 head.

Get one listed for a 95 - 97 Cavy 2.2. You'll have to shave a slight tab off your head so it'll bolt up flush, but it's nothing big at all. Otherwise that's it, you might need to get part of the downpipe rebent because of your auto, or other things in the way. But the header should work fine.
Sorry to give miss information. Thanks guys for clearing it up. I learn something new everyday.
