Hi All, I have been surfing the 6GA boards for a couple years now, digging into everything from N/A builds to turbo builds, F23 tunability to popular swaps and so on. Lots of great information is archived in these threads, thanks to all those who have posted! I have a 99 EX F23A1 Coupe 5-Spd with about 121k miles, that I have owned for about 4 years as the 3rd owner (my best friend bought it from the original owner <1 yr before that at 80k mi). By the looks of the oil starting to leak when I drive it a little hard, the head gasket is due for replacing. I daily a 2017 WRX, so the Accord has been relegated to weekend/project car status. And as much as my wife hates it, I can’t seem to justify parting ways with it for how much fun it can be to drive and how sexy that body looks. Especially considering the pennies you get for it on the used market. So as I debate what the future role of this car will be, I am tempted to go down the road low-boost turb build route. This would be my first build, and I know from surfing the boards the F23 isn’t the “friendliest” platform to build. But I am thrilled by how it could play out. My key question is this: given the smog regulations in California, is doing a street-legal turbo build even possible? I’m a bit flabbergasted among the options I have heard of with piggy back setups, stand-alone setups, OBD-1 conversions and so on. Any guidance or help on this would be greatly appreciated!
