What would it take to convert crossfire to non-crossfire? Any computer mods or just carb mods. Want to buy 81 but looking at an 82 and have not heard good things about crossfire system.

Shyhigh, what are your 'plans' for the C3? Is is strictly for daily driving? Many highway miles? Make a 'Stop-Light Bandit' out of it? If the '82 you're looking at is in good working order, and you don't mind it running high-15/low-16 second ETs, leave the CF alone. I've put 7,000+ miles on mine in three summers; not many, granted, but I've had NO problems what-so-ever, AND I get 23+ MPG @ 75 MPH! I'm in contact with other CF-owners, who tell me that some mods (exhaust, gear-swap) can make these run low-15/high 14 second ETs. You can investigate the Cross-Fire Vault for even more technical info. One young man runs in the 11s @ 119+ MPH (that is Z06-style times, my friend!) with gears, exhaust, and a healthy dose of N2O. Don't dis-regard the CF right away; it may be for you! :chevy :chevy :chevy

Cross fires run fine, they just got a bad rap.

If you want to convert to non-computer control:
Replace intake manifold, carb, distributor.
You may also need a way to have the transmission do lock-up in fourth gear, and then you can ditch the computer as well. Kit's for lock-up range from $75 -$250 depending on features.

If you get rid of the distributor, let me know. I need a computer controled HEI distributor.

DesertDawg ran a 15.13 in a stock (bone stock) '82 Collectors edition.
With a smaller person, some race gas, good exhaust system, rear gear swap - you could be in 14.7 range.

The 'Dawg' told me he'd added Borla mufflers to his C.E. at EXACTLY the same time the insides of his catalytic converter 'fell out' :lol: :D :lolg: . I'd think if he'd ('DesertDawg') install 2.5" exhaust and headers, he'd run high-14s (easily), and a with a gear swap (3.55s?), mid-14s. A guy told me he picked-up 6/tenths, going from the stock 2.87s to 3.55s alone! :eek: I'm not too sure that 'racing gas' will help a 9:1 motor. I seem to remember guys with 5.0 Mustangs in the late-'80s saying that racing gas actually HURT their ETs, but I can't remember exactly why..... :confused:

Desertdawg

Yes the crossfire is a good setup, it starts every for me. and I have had zero problems with it. They are not screamers, more civilized than the older vettes but still fun.

If you get the 82, and still want to yank the crossfire, I will take the manifold and throttle bodiesoff your hands, like Bseery said you only need a few parts to change it out.

And welcome to the Corvette Forum. :seeya

You're not planning on going faster are you? Addicted to the strip?

Desertdawg

No, Just want it to run a little better. :D

I don't have crossfire, but I'd like to have one. I think the benefits of fuel injection are considerable. I'd gladly give up some performance for the lack of hassle and improved fuel economy.

Twin_Turbo

I've got a couple of them crossfire systems lying around... if only shipping wasn't as expensive I'd be rid of that poopie already :)

Skyhigh82

Thanks for all your inputs. I'll see what price I can get the 82 for.

I have an 82 with 105K miles on it. Runs great ...I use it to cruise....its definitely not a street light racer.

Desertdawg

Tease me why dont you..... :mad :D

the shipping would be more than the parts are worth. :lol:

Twin_Turbo

Well... if shipping is via a 4-6 week method it's pretty reasonable. I've had a huge radiator (31X17X6) shipped for about 50$

I still use my 82 as my daily driver...running without problems for over a year now,with very decent fuel economy.
Not the fastest Vette around,but very good for daily use!

BSeery

The shipping on two exhaust manifolds (not nearly as big or heavy as a fully loaded intake manifold) from AZ to England ran $118.00

Twin_Turbo

hmm.. that was not 4-6 weeks USPS was it?

BSeery

I think FedEx was the cheapest believe it or not. And they did a 7-10 day. UPS and USPS were more and would take 4-6 weeks.

Find out the weight of a complete intake, and dimensions giving 4"s all the way around for packing material and you can get an estimate on shipping.

Desertdawg

SO Marck, if shipping is not very much. How much do you want for your intake and throttle bodies? Together or seperate.....

Twin_Turbo

don't have TB's... sold my last set some time ago. Might want to check over on the crossfire vault. Also, maybe Ken73 has an intake, I think he has a few and will even do the work on them.
