79 s130 carb conversion
just wondering if this conversion is worth my moneys, about how much hp to be gained from a 390cfm holley and the arizona z car 4bbl manifold?-like to be rid of the primitive fuel injection on this thing.
thanks
thanks

If there's nothing wrong with the F.I., its not worth it. You'll waste your money on something that doesn't make any more power than the F.I. All you're doing is changing your fuel delivery system and reducing your gas mileage. Plus more stops to the gas station.

No offense but your "z spe******t mechanic" is either a shister or an idiot since he knows pretty much nothing about the stock EFI system. Anyone who knows anything about tuning an engine (and I don't know a whole lot myself but I do) know that your power comes from your spark timing advance which is based on vaccum and mechanical advance on the NA and the ECU controls it on the turbo. You can squeeze a little from tricking the stock AFM to enrichen the mixture but it's hardly worth it unless you have a cam in there that you want to try to get something out. There is no beating a tunable system though....
Going from a primative EFI to a carb is still going backwards. You can still only tune the AFR and only roughly at that with a carb....

Your best bet is a z31 efi swap if you don't want to deal with completely stone age efi.

Fixed. 
It has "Cialis" in it, which was on the anti-spam list.
And we've discussed the "EFI to CARB conversion" soooo many times... How many new cars come from the factory w/ carbs these days?

Also, you asked a VERY generic question, and one that has been asked and answered many times before... we have discussed 4barrel swaps, triples, etc...
Also, you recently asked "how much power can a stock L28E handle from being turbocharged?" ( https://www.zdriver.com/forums/280zx-performance-technical-79/l28e-t-33938/ ).
Are you wanting a turbo, a carb, a 10 second car?
Like Jerry Maguire says... help me help you.

haha how about you go ask that question on Zcar.com
make sure you put on your flame retardant suit before TonyD gets ahold of you (:
oh the joy of being a young high school kid who knows everything, and they all seem to have a "z specialist who owns their own shop"

Im out of college with a 2 year degree, and I would be the first person to tell you that I dont know eveything. and I do have a friend with his own Z shop you can drive out to Idaho if you dont believe me, stop making assumptions about me for questioning an answer because I heard something different.
Nismopick- I was referring to his insulting comments regarding my good friend("the no nothing z mechanic of 20 years")
Im trying to figure out my options and choose the best one by process of elimination
"No offense but your "z spe******t mechanic" is either a shister or an idiot since he knows pretty much nothing about the stock EFI system."
most forums would have booted his *** by now, just saying.

/Sarcasm.
I can think of MANY other / better things to spend $400-$600 on than a carb setup that will actually make worth while power.

all I did was question an answer, and that means I don't want to listen? ok.
I heard what was said
-most help with issue early on
-Z31 ecu swap
-less mileage by 2mpg (debatable)
-go check the other threads
-tell him what we think he wants to hear instead of answering his question
bout sums it up
instigation is clearly key in ****ing up someones thread
RB25 it is then. since Im clearly bothering everyone with my questions

You aren't "bothering" anyone. This forum is here to help everyone, but as you previously stated:
And when you state something like this, what do you expect us to say???
The 280zx EFI is as simple as EFI gets.

note: I did search. now maybe I didnt search long enough or with the right terms but all I found was my thread and a bunch of other stuff that had very little to do with answering my question.
Saw the 4bbl conversion; got excited about it because I keep having to retune my **** and posted without taking a whole lot of time to search. I guess Im in the mood to diffuse this argument ATM.

let me give you a piece of GOOD advice, do your searching on hybridz.org and zcar.com
the archives there have GOBS of information that is FACTUAL evidence, not hear say like some of the information is on here.
