I like my little car just the way it is.
A 30K service that's 2K old doesn't hurt either...

308 upgrades
I own a 1979 308 GTS. I would like to upgrade the performance. So far, it has been kind of slow. I had the major service performed twice because the last mechanic didn't trust the first one.
I would like to get everyones opinion on the Tubi exhaust system, ignition systems and having larger carbs installed. I want my car to sound and perrform like a Ferari should. As things stand now, my Honda Accord is faster.

I was just thinking on the stock and just serviced line. Getting your car serviced by a reputable place chances are does in fact make it faster. A fair number of cars are not timed exactly and not tuned well at all (distributors and carburetors). There are a good number of slow 308s that at one time were pretty fast. If it's all tuned by someone that knows what they're doing and takes the time all the 308s are respectable in acceleration. None of this really matters though, to each his own and enjoy what you like. I think a large portion of my modifications are fed by my mechanical fascination and not really by a need or even a rational use. As I'm typing this though I'm about to go work on the con rods again so I guess there is no hope for me.
Sounds like you understand what you're doing. What is the stock compression ratio on a 308? I thought it was rather high. Also, do you know how strong the stock pistons and rods are? What I'm getting at is are the stock 308's candidates for forced induction.bretm said:Even if the 308s are a little slower (most of them). They are a much more intimate car than the newer Ferraris, a true sports car. I'm in the never ending process of modding my 308. When it goes back together (pending my receival of go fast parts and working around school and work) I will be running: port and polished heads w/ new stock springs, viton guides, ground seats, etc. about 10.5-10.75:1 comp, cams reground by elgin, polished and balanced stock rods, no cat, crank vent system, and it will all be managed by an electromotive tec3 ignition/injection system. I might also swap the clutch/flywheel for a lighter setup depending on how much money i have alotted when i get the pistons and cams back and buy the tec3. It should be pretty respectable. After this I'm gonna focus on the rest of the car (lightening, more modern handling, braking, etc). Down the road a couple years I plan on really turning the engine into a beast (a small beast, I mean it's only 3.0L, but a beast nonetheless).
Also, someone else mentioned hp gains by going with a distributorless ignition.......save your money. Airflow is all that really counts.
The older,70s USA carbed 308s were only 8.8 to1 compression ratio. The 208 euro carbed model used forced air induction to up the hp.
308s run a 8.6:1 comp (9.2:1 for euro ones). They are candidates for turbocharging and Norwood actually has a bolt on twin turbo system for $5900 right now. 8.6:1 is pretty low nowadays. BMW runs 10.2:1 on their 3 liter engines, Ferrari runs 10.8:1 on the 355 and 11:1 on the 360. Since these are larger engines the 308 would have no problem running them. That would work out to running like 11.5-12:1 on the 308s 3 liter engine. (How they managed to run 11:1 on the 6 liter enzo that just came out is beyond me, I suspect it has to do with that pented combustion chamber, but I'm going off on a tangent here). The higher the comp the greater chance of detonation, with an adjustable ignition system you can adjust the timing to compensate for this, but for the most part you are better off running like 10.5 to 10.75 on a 308 and running some good advance than you are running 11.5:1 and little advance. Since Ferrari has to pass emissions and can't run as much advance they run a slightly higher comp. Also the fact that they have unlimited resources and have been doing it for like 50 years helps them have a slight edge over me for instance when it comes to picking comps, advance, etc. Ah, but I have that emissions advantage.
The 288 ran 7.6:1 with like .7Bar boost on it's 2.85L engine. The F40 ran a little more boost on it's 3.0L engine (same block as 308), not sure of the comp though and I'm at home so I can't look it up. Although the 308 might have a tendency to run a little hot, I don't see a problem with running the same pistons and rods and same comp. You might need different gaskets though, in particular the head gasket, to take the added strain. The rods from Ferrari are pretty stout, as are the pistons. They could easily handle the extra power.

Absolutely.Remember "Drive your Ferrari for what it is, not for what it isn't."
To each his own.
sorry meant to say QVs 8.6:1, the others are like Magoo said 8.8:1. You can get pistons made up for around $1000 if lower comp were desired for a turbo engine. Norwood and Nick Scianna are the best to talk to about turbocharging a 308.

Bret, You are on the ball. I was going to repeat the 8.8to1 versus the 8.6 to1 but you caught it. Good interception. Magoo
I noticed that no one posted Nick Sciannas website! Here it is:
www.nicksforzaferrari.com -he is a true gentleman and knows how to get more ponies out of a Ferrari 8 cylinder. I highly recommend you contact him and I love his site, its like a toy store!

82 308 GTSi
It has and electronic ignition but I think I could put on some new MSD or Crane boxes, big coils, good wire. Change the timeing to something more aggressive What do you think? I'm open. Thanks RC
I want to get more Hp. I have a new flowmaster no cat exhaust, a Kand N intake filter.Edward Gault said:I cannot estimate the HP gain from the DIS but I have driven other GTSIs and older carbed versions and even a 328 and not bragging but my car seemed faster and ran better than any of them. I was really disappointed with the 328. I had always heard that it was the ultimate Ferrari but I was really disappointed. My car was better. I even let the other owners drive my car and they all agreed that there was something special about my 308.
