Welcome to NICO.
IAP is our sponsor, and a few guys have purchased and installed their kits (^ Greg is working on it )
There are a bunch of members from the DC area, so you shouldnt have a problem getting help for some smaller projects.
A shop called RedShift does work on 240's. I met a guy that worked there (Jon), but I dont know the quality of their work. But they might be worth a call/visit.

Theres a shop Ive heard great things about (they build drift cars too), but theyre in Baltimore and I cant remember their name.
