Replacing The Crossfire
I want to replace my crossfire injection on my 84 with some sort of injection system. I've looked around on eBay and Craigslist for some sort of injection and I'm slightly lost... I looked on Edlebrock for some sort of multi-port injection and it looks like its for 87+ 350...
Anyone have any advice on where to look for a good TPI system or something like it that'll help me provide a good base for upgrading?
Thanks

I have the wire harness & computer for the 84 to run a TPI system from howell industries. Could sell it to you. A complete TPI unit on ebay will run you about $250 on ebay.
By the way I have the exact same car as you even the same color. I bought an 85 so I never got around to changing to the TPI on my 84.

Blasphemy just occurred.
CFI will be here soon to assign you "penance" to pay....
There are many multi page threads on this very subject. Many epic battles of wits and what is and what is not "better" have been posted.

Amen!First, before you can get any meaningful help, we have to know why. What is it about the Crossfire that you want to cure, eliminate, or fix. It is hard to advise you on how to get somewhere if we don't know where you want to go. As a starter, there is little or nothing to be gained from swapping to a stock TPI.

The Crossfire is not a bad nor unreliable method of fueling. It's just been misunderstood and ignored. Merely porting the CFI intake-which only costs you time if you do it yourself, and still less than purchasing all the TPI goodies if you have it done, can net you a half second drop in your quarter mile times and provide more torque everywhere. Whatever you decide-good luck and welcome.

A solution to WHAT though?
My CFI car made ~320 hp when I sold it, through the CFI intake and TB's. Also got ~24 mpg on the highway. I'm not sure that the car I had w/CFI induction...needed a "solution".

A solution other than CFI. Every time this comes up the poster gets flamed. I certainly wouldn't want to change CFI to TPI, but punishing the guy for asking a simple question seems a bit harsh.

^^You pulled a ninja edit on me!!
Well, if asking for motivation is a challenge, so be it.....I guess.
Just to be clear, from where I sit, if we know what He is trying to do we can steer him.
just taking the CFI off because that is what every body says to do is another...
I'm over on the RX7 forum and I mention what I traded my RX7 for....the first damn reply is "oh that crappy Xfire engine" The guy had no clue about C4s but He KNEW to bag on the Xfire. He admitted freely later that he had no knowledge of C4s yet felt fully comfortable in bagging on the Xfire.
It's almost the same phenom that Live bands deal with.......inevitably some drunk will holler out "Freebird" and hold his lighter up. Does the drunk own a Lynyrd Skynyrd album??? not really but that is beside the point.....He knows to request "Freebird" 'cause that is what every body request.

I didn't think that I flamed or punished him (?). Just stated my own results is all.

Yes this is a simple question and the responses are on the harsh side.
But this is like that other guy that was worried about getting more water flow out of his Water Pump....His Temps where way up to ~210° mark!! He felt they should stay down at 175° like when He was on the highway.
How do you cure what is normal?? Why do you modify what is perfectly able to give you adequate flow or fuel delivery??
example:
I want to modify my wheels
Why? They are all round......all four of them... Really?...Round??...I see your point.

The man asked about replacing his CFI. I merely asked what aspect of the CFI he wanted improve upon. What he wants to accomplish, what he wants to improve, and what he can spend, makes a difference in the recommendation. Lighten up. I am making a sincere attempt to help the guy. Don't scare him off.

What challenge?
A solution to WHAT? Who was punishing anyone. The simple question was without specificity. Do you feel challenged at the haberdashery if you are asked, for what occasion? What color? Do you have a style in mind? Do you get pissed at the tire salesman if he asks you what you want the tires for? Long life, traction, good ride, etc? I, possibly more than most, am familiar with the limitations of the Crossfire. I have never contended it was the greatest thing since sliced bread, just that it isn't as bad as all the bad press makes it out to be.

Cool!
Whose post do you consider a challenge?
!
A solution to WHAT other than CFI? Who do you think flamed him? Who are you saying punished him? Who has been harsh?

I don't have to answer to you. BTW Your second question makes no sense. Go back and read the post again. Are you drinking?

CFI might be forward and blunt most of the time but not this time.
Badduck I really don't see what your problem is here, you're trying to make something out of nothing. If the guy wants a TPI no questions asked he got a solution to it in the first response. However this may not be the case if he wants to rev higher then going to TPI isn't worth the hassle. CFI is right more information is required.
what kind of upgrades are you looking for? From what I've heard you can upgrade a CFI nearly the same as a TPI. If you want to rev higher you'd be looking at LT1 intakes and minirams.

Sorry, work and school have been murdering me! nobody has scared me away..
As for my means and reason why I want to get rid of the CFI is that I am just not a fan of throttlebody injections... I'd like to get a good TPI system if at all possible because it is what I am more familiar with and what my mechanic likes working with (he works for free if I have something he likes to work on).
I'm not planning on going crazy with this car, I'd just like to beat some of my rivals (WRXs, a few BMWs and my friends Audi TT Twin Turbo) and I believe a good TPI system is the way to go. But before I dive head first into this, I figured getting some opinions from seasoned veterans who may have done this before may be a good idea.
I'm not here to defend TPI or say CFI is garbage, its just that CFI isn't for me. All I'm looking for is some input from people who are willing to provide it
