Twin TBI... Throttle Body Injection, two injectors.

Several GM cars of that era used either one or two of those throttle body injectors. It was a pretty nice setup, compared to carbureted engines. I had a new '84 with the C/F system an liked it fine. It wasn't any more or less powerful than any other base Corvette engines of that time period. But "power" wasn't my main concern, anyway.

As long as the required hardware for that system is present and operating properly, the C/F system is nice. It is an OBD I system with trouble codes you can use to diagnose 'system' problems. If the OBD I system is not working, the computer may have issues.

A more modern "direct injection" system is better, of course; but nothing wrong with the throttle body approach.

Just my personal prejudice, I would stay away from that model year due to it being the only year the C3 had crossfire, few people know how to work on it, plus the use of the computer and it's early OBD1 technology.

These are the exact reasons why I was drawn to the 82 CE. The engine is not rocket science and there are plenty of good mechanics with an old brick that can work on them. I am having a ball with mine.

I'm happy to hear both of you have no issues but I also have come across other cases that have not worked out so well.

If you have found a car that you like, don’t be afraid of the CFI engine, especially if you plan to do the work yourself. There are plenty of used Snap On MT2500s that will give you all the engine data you need and there’s is a wealth of info available, here on this forum, and around the web. Be sure to purchase a shop manual. I bought my 82 that had sat in a warehouse for 18 years of its life. It was not well maintained and I knew very little about the car and the engine. But I learned about it and 8 months later, I’m enjoying the heck out of it.
Too many people think they can adjust their way out of engine problems. It’s not a carburetor..it’s a fuel injected engine controlled by a computer.
Good luck with whatever you buy!

Had one... Bought a HypeTech chip and it fixed 90% of the run & trans issues.

Low HP smog motor - 180 HP

Best dam seats in the Corvette line including my 08 C6. But, I did have a buddy recover them and upgrade the foam. My wife slept 90% of a 1200 mile trip after the update. I also update the shocks.

I have owned my 82 for 25 years now and have gone where most CFI owners wouldn't think about going with their motors while still using the CFI. Why, because I can and to prove a point, that CFI can run well if you do it right. There is nothing wrong with CFI as long as you know what your doing just like anything else. You can not adjust a TBI like a carb, it doesn't work that way.

The above post says 180HP, I'm assuming you mean to the rear and that would be a strong runner if stock for sure with only 200hp under the hood stock for 82 and 205hp in 84. Typically, 165-175hp at the rear is a typical dyno number, which still isn't bad.

If you are mechanically inclined and don't mind learning the few quirks of CFI, then buy the car and have fun.

I bought my 82 a few years ago, it ran a little rough, so I replaced the fuel pump, filter and the injectors... Runs great...
