I've got a 90 Civic Hatch and am looking to find a one-stop shop for things like engine swap, turbo installation, etc.

I'm located in the Whittier area and just wanted to know if anyone knew of any good reputable shops in the SoCal area that can do these things. It doesn't have to be close to Whittier, I just want a place that people think is on the up and up.

Thanks in advance.
