Cross fire to carb
i recently got rid of my crossfire injection put a edelbrock torker 2 intake with a 650 cfm holley double pumper. Got a vacuum advance dizzy. All I need now is a fuel regulator
|
Cool. Should make about the same power as if you had ported the stock intake. :thumbs:
|
Fuel injectors both clogged was not worth replacing both at 110 each.

Let me hear it I want as much horsepower as possible

110 each for TBI injectors is too much. REMAN TBI IJNECTOR: $30 BUX

Definitely plan on going to track got the whole new setupfor 70 bucks from The app OfferUp. https://cimg6.ibsrv.net/gimg/www.cor...16750569a3.jpg

If anybody wants crosssfire parts I will sell them cheap I am in central New Jersey

That carb isn't a "double pumper", BTW. :thumbs: . |

Carb looks a little tired. I would rebuild it before I relied on it.
|
What can use to make the carb shine again.

couldnt have possibly picked a worse air filter
Jdog, please dont use that "filter" as is; you have zero filtering properties. |

I'll see how it runs without the rebuild. But plan on rebuilding carb anyways. As for the air filter what do you suggest in terms of a better one seems I will have to cut a hole in the hood either way

Unless your goal is to modify the hood, there is no reason to cut a hole in the hood. The 80 and 81s used a carb set up as you have, so the clearance is allready accounted for. The air cleaner in your photo is not (not) even remotely compatible. Get something like Taylor suggests and put the Saws-all back in the box. |

If you want to keep it EFI, you could do this. Your stock wiring & ecm will hook up & run it. The junkyards are full of tbi units, crossfire is basically the thing as a 2 barrel tbi.

This project could have definitely used a little more prior planning.

So first off.. the cfi can work if it works at all. The intake you mention can be seen here and they manufacturer also gives a cam recommendation etc.
http://www.edelbrock.com/automotive/...orker-sb.shtml I'm not a cfi guy and don't care to be. I can tell you it was built with a purpose. that purpose was not to give you a muscle car. You now have an intake that will flow decent if you get a cam to match it and either work the heads or change them and add headers. If it goes 6k+ like it claims and a cam and heads to support it you'll be waiting for a cfi car to catch up to you, so you can drag them again. You can port all you want and play with the cfi, a few guys made it their goal to make it "perform" now you have what is called bolt on parts, the more you bolt on the more power you'll be able to make. I don't know the flow rate comparisons between the 2 intakes and in the last 30+ years surely somebody did one and wrote it down somewhere, but Edelbrock did the research, all you have to do is buy the parts. Don't feel bad you changed the car. Feel bad you put that stuff on in that condition and considered doing that air cleaner set up. |

Don't feel bad you changed the car. What he has, is a single plane intake on a smogger long block. What that equals is a terrible combo; the intake ensures no low end torque...the cam heads and exhaust ensure no top end hp. Maybe it will make "OK power" from like 3500-4502 rpm? Maybe. He'd have had a faster, better running car if he'd kept the CFI intake. :thumbs: But you're right Polo; "all he needs" now, since he already invested in that big dollar intake and carb, is a cheap set of heads, a good cam, headers and full exhaust and he'll have a screamer. Yep...he's well on his way. :crazy: |
Update : got distributor setup too dead center go to start the car and exactly the same is happening . No combustion in even cylinders. About to bring to shop does not make any sense at all why if it has spark and fuel and compression and air why it will only run on half the cylinders.

Well that was a lot of rhetoric. "Edelbrock did the research..." Well there you have it folks....PROOF! (of who knows what). Edelbrock may have done some research (probably mostly packaging modeling) but the research that they did likely wasn't a Torker II on a 200 hp long block.

Yep...he's well on his way. :crazy: OP what is your purpose here? Do you just want it to drive or be able to make power at some point? I think what tom400cfi is trying to say is you should look for more of a lower rpm intake to stick on it, since the peak torque on the stock POS is like 290TQ @ 2800 and 205HP @4300 rpm. You could try to match that, many others used the performer series. Unless you for some reason don't have the stock parts on the motor anymore, then you might be able to run it up higher. Do you know your rear gears? I think some 84's can have a little lower gear than most of the TPI models. If you want to build it, do all the other stuff and the intake is fine. Let us know how it goes, I doubt it but you might like it. |
No I am not off 180 degrees and no popping either is the hei distributor computer controlled. I get spark when starter is moving engine but as soon as it gets to 500 rpm no spark from even cylinders.

All there is to it. You run the vacuum line to ported spark and you're done. The one in your pic is the right one. Could it be bad? Module or something? |
This engine only has 70000 miles on it I plan on get it running right then eventually rebuild the engine at 100000 miles
|
But this god dang half engine not firing crap is really pissing me off
|
Tight rocker arms? Check compression.

This thread just makes me sad/cringe...
Brandonbeast bought an 84 where the previous owner did a total hack job of a carb conversion... Good luck! I personally laid down some money and modified my existing CFI to be more fun... :) |

Because earlier, you said:

So...what is really happening, here?
If my old TBI memory comes back to me, there is a main and a secondary that feeds each side (odd and even) side of the engine. There are IACs that work independently for each of the TBI. The TPS is only on the main as is the MAP sensor with the EGR pulling from the secondary. So... because engine is "morphed" could the computer still think that twin TBI are in place and when the rpms get above the idle, the computer looks for normal (escalating) TPS and IAC input values and effectively "shuts down" the secondary (the even number cylinders) as there is no signal and the computer becomes confused? Sure its crazy (and I'm at work, so I can't blame it on alcohol) but I'm not coming up with anything else? BTW... my '82 XFire was a rock solid performer. I'd get another in a heartbeat. |
^Hard to know for sure in this thread, but I think that the ECM is totally out of the picture now. He has a carb, and a mechanical distributor. Computer couldn't shut down anything if it wanted to, at this point. It may not even have the ECM in the car.

Used vacuum advance distributor didn't work so I have the stock one controlled by the computer on there. How would I wire up the stock distributor to not use the computer ?

New distributor same problem completely stumped only runs on drivers side cylinders.?!?!?!

No heat from passenger headers and no exhaust from passenger exhaust.

https://cimg5.ibsrv.net/gimg/www.cor...87d98202ed.jpgValves a lil loose

Low and behold these garbage valve covers caused the valves not to open properly now time to put everything together😁
|
I put them on upside down my bad . I know this engine inside and out simple mistake. Anybody know how to use this fuel regulator.

Bent pushrods will cause loose valves. You need help from someone who knows engines. Are you having fun yet? (I forgot to read post #4) :ack: |
Any idea how this works inlet outlet adjust ?https://cimg1.ibsrv.net/gimg/www.cor...ac461798cb.jpg
