Welcome to the community.

As a former owner of a Fiero, I will be watching this build with anticipation. There are a few that have done the swap. One of them had a website that appeared to have some really good info on it. The address escapes me at the moment though. You might do a google search on L67 swap + Fiero or something like that. But there are some out there and they are running pretty quick at the track.
