Hey Jared, the original crx is treating me well, reliable but ugly and needing paint which I haven't gotten around too. I actually found a genuine SIR that I bought last apr, had registered legit and all only to have it stolen before christmas. That SIR was sweet, all 100% original and in great shape. Thieves stripped it, cut off the glass roof and burned the shell in the street, which was probably close to where it was chopped. (there is thread about it on h-tech) I still have what's left in my garage and toy with the idea of converting my USDM model to RHD.
Bushings on the teg will be easy. Half the work of getting the factory ones out is complete since the energy suspension ones will just pop out. All you have to is press the new ones in. Go mugen hard bushings if you got money to burn. Let me know if I can help, as I have an arbor press.
