I had this thought... again, this is just a thought. All input is welcome. California smog rules say that all cars 1975 and newer need to be smogged(bull$**** raquet) and yes, Ferrari's too. To get around that and just pay my dues every year I would need to get something older. Say for example, I were to take a 1974 365GT4, upgrade the suspension, brakes, swap the engine out with a 512tr and.. maybe, give it a twin turbo respirator to help it breath easier , needless to say, the thing would be monsterously fast! Would I essentially be damaging the car overall? or taking a series, making it a custom and putting it on a whole other level? (Everyone says get the 512BBi and I would agree! BUT, 512BBi production was around '76-'84... taking my idea back into the smog sniffer every other year with a big fat "FAIL - NOT OEM".) Car Value - Obviously, I'm not entirely a purist. My biggest fear would be, "Hey Gabe, you took a car that had descent potential for resale, chopped it up and made it worse!" I would not looking for much return if it came time to sell something like this.... it would be make offer. Anyone have a view on this?
Not sure how they administer the smog tests in Cali. The 512TR motor would run cleaner though the carbed one! So with that in mind you could buy a newer model perhaps if you are serious about installing a newer fuel injected engine. Seriously i believe most states want you to pass the smog requirements based on the age on the year of manufacture of the car or engine whichever is newer. However im guessing without OBD 1 or 2, theres no way they will know that you swapped out engines.
for the 365 GT4 Boxer ??? 4390 cc's versus 4942 ? Should bolt right on with some small adjustments(in theory)
365BBs are relatively rare, I think once you got the car in reality it would be hard to justify modifying it as putiing in a turbo would be quite an project since you would need to go to FI and making the other mods for it to work, not to say you couldn't do it but the early BBs are getting very collectible now and something like this is very radical, however if you found a spare TR motor to modify and kept the 365 motor stock that would be an option. It would be better and much cheaper to go the na route on this car with some BB LM or P6 type cams and head work, you could get 450 hp easily and the car would be a rocket, keep in mind 365BBs weigh as much as a US 308 so it would be very fast but not quite the same as a 700hp turbo model. Part of the major thrill to me with the carbed Boxers is the sounds the motors make and going to a turbo FI setup would change that. Even in stock form these cars are plenty fast enough to get yourself in trouble, I would say drive one and see how you feel about modding one after that. I think doing a radical mod such as a turbo 512 motor you would have a car thats very hard to sell and you would damage it's collectabilty and resale but if you accepted that fact it would be your car to do what you want with it, if you just did some cams and head work I think it would benefit the cars value and certainly not take from it, the same with suspension and brakes mods.

That said, the question really is how much $ are you willing to spend? Non-reversible modifications are frowned upon in terms of resale. But if you are willing to spend the 60-70k (ballpark) for the BB, and the 10-15k for the 512TR/M engine, and the 10k+ to make it all work, go for it! Just do not expect the vast majority of potential buyers from paying you a penny over the value of the BB base car. Think of the Convert Koenig Twin Turbo 512M Will just got. That car cost well over 100k to make, yet I am certain it fetched less then the going rate for standard 512Ms. Just be fore warned the car already is a bit to handle, and adding more power to it...sounds delightful from a drivers point of view! Honestly it would prob. be just as hard (and as fast), but much cheaper to get a 365GT4 and drop a 456 or 550 engine into it. Now that would be a sleeper!
Omar: For the first car that you posted, the designation is actually "365 GT4 2+2" (one sitting in the driveway here right now that will go on a 300 mile run today). The second car is "365 GT4/BB". The GT4/BB is the rarest of all of the Boxers (only 387 made) and yes, the prices are going up.
First I'll say I am on the east coast so my info might be very wrong, but what I've always heard is that CA goes by the engines year on manufacture for smog...so fitting a newer engine means you need to pass the newer smog test NO? Then. A turbo or supercharger can be done as a bolt-on with no internal mods required. You will need to make some custom parts to bolt-on, but it can be done. If you do the work yourself plan $6k - $10K for parts. Multiply by at least 2 and maybe 3 to drop it off somewhere and pick it up finished.
True, I was referring to conventions used on Ferrarichat to avoid confusion (which seems to have occurred as evident by some of the earlier posts.)
