I used to own a 77 GTB and also owned an 84 GTS and an 85 GTB. Here is my take..... For outright coolness, the carb cars are big winners. You can argue HP all you want, but in testing, the QV's posted quicker acceleration than carb cars. This could be because QV's have better bottom end and lower gears. In any event, 308's are not fast in stock form, so it's all just academic. The QV's advantages are: 1. more tractable motor 2. longer lasting motor (better materials) 3. personally, I think the carb vs injection reliability is a wash. 4. The digiplexes in FI cars do fail and are no longer made. 5. QV has updated interior, better laid out and seat stitching seems to hold up better. 6. QV steering and clutch is lighter, less work. 7. cooling system is better (capacity is increased as well as other improvements) However, even QV's could benefit from more efficient cooling. 8. 16 inch wheels beginning in late 83. 9. rust proofing beginning in 84. 10. air pump eliminated and change to single cat in 84, supposedly make 5 more hp than 83. Conclusions: If I were looking for a 308 for occasional pleasure drive or possibly show car, I would look for a really nice 76-77 GTB. They are getting hard to find. The carb motors have a magic FI can't match. Pre 78 cars have no cats. Nice QV's are more plentiful and will do better, last longer when driven a lot. I would not care if it was an 84 or 85. The only difference is the fuse box cover was no longer attached with velcro in 85. I would pay less for an 83 all factors being equal, especially if it has 390 wheels. As a final note, the 85 GTB was a really nice driving car even if not a killer performer. Unfortunately, QV GTB's are very rare in the US. Dave | ||

I bought an injected car for the following reasons: 1) electronic ignition is bullet proof (assuming motoronic boxes don't get wet). 2) From I think 83 on the cars are rust proofed. 3) No problems passing CA smog with a Fuel injected car (assuming system is in good working order, versus a car with carburetors.

I originally wanted an injected car and am much happier with a carbed car...much easier to diagnose problems....Had Bosch FI on my P-cars and when the little parts go its a pain to trace them down (fuel accumulators,cold start valves,aux air valves etc) and those little bits are are costly. | ||

My old '75 dyno'd at 198 rwhp, with 10,000 miles on the plugs, original plug wires that needed changing, very dirty air filter, and an A/F ratio that was, err, less than optimum (checking that was the reason that I had it dyno'd). And, yeah, I've corrected all of the above. I'd like to dyno again, just to see.......... | ||

Steve, and it's bone stock. I am not arguing with you. I am just pointing out the specific's of my car. Matt | ||

Matt, in regards to cooling. the early 308 carbs had radiator vents behind the headlights only and two little fans. the QV added an additional vent along the hood line allowing more hot air out. It also had bigger and better fans. The Radiator was also angled. Steve, My car dyno'd in Nov 02 @ 206.2 at the wheel Approx 253- 256 HP at the flywheel. | ||

In US trim, I don't think a carbed 308 has more power than a 308QV -- anybody got a dyno run from a US 308QV? Another "advantage" for the '85 US 308QV vs. a carbed US 308 is that there's no belt-driven air pump. | ||

"3. FI was/is concidered better then carburation. 4. Better engine cooling." What do people consider to be better about the fuel injection in the 308? When you say "Better engine cooling" what does that mean exactly? That the older 308 have problems overheating? The newer 308 just keep the engine at a constantly lower temp? I am not trying to argue, just trying to learn. Thanks so far for the info. | ||

"doesn't the carb'd 308 produce more hp"  Yes it does!!! | ||

Matt, I have a 78 carb and I would not trade it for a QV but, I can see why people want a 85 QV. 1. it's the last year of the 308 so it is has a "modern" interior. 2. the redesigned targa (80) does not leak (has much) has the original design 3. FI was/is concidered better then carburation. 4. Better engine cooling. 5. bigger wheels (16 vs. 14's on the carbs) 6. lower miles being the car is young, usually. Matt | ||

While looking at many different profiles of F-chatters, I noticed that the ones that want a 308 want an 1985 308. Can someone explain to me why this is? I know that it is fuel injected and has 4 valves per cylinder, but doesn't the carb'd 308 produce more hp? |
