There's a guy in Seattle Washington area who brings his bug eye wrx the pacific race ways and he has a ls1 in it he daily drives it and drifts it on the weekends he said it cost him right under 5000 to do the swap and he made almost all of it back by selling his stock parts he gets over 25mpg and he drifts it almost every weekend I've been thinking of doing this ls1 swap in my 96 wagon only problem guy has had is he blew like 3 rear ends I'm pretty sure he said he was running a rx7 one now and it's holding up really good and the best part is he did it all in about a full week and no major modifications were made to engine bay so it has and can be done feasibly just depends on what kind of knowledge you have
