Which one is better? I know some of the small details with them. But not a whole lot. My dad is really getting on my nerves... tell him I want to get the 4age and he's like "but your carburator! it's better you can fix it (thats where I think no I couldn't lol)" and he goes on about everything bad about efi, he's like that negative everything with stuff he doesn't like. SO I want some other opinions

Yea my dad is kinda like that but i'd have to say get a 4age if you get one get a 10.3 comp red top like mine i know they came in 91s maybe 90s to i dont know how reliable carbs are never worked on em or anything but efi does get more problems like my engine light keeps coming on and i cant get a code out of it every time i try it just shuts off!!! but efi is easyer to work on over all but its hard to install if you wanna get a 4age get the 20v id say cuz its got quad throtle bodies.

Im gonna have to disagree and say carbs are easier...theres no electronics involved witha carburateur. So if it f's up its simple to fix and cheaper. This is what i was told from my toyota dealership.

I don't want the 20v yet... regular 4age for now, getting a gts for the small parts and such that I will need so that I can just drop the engine into my car, and switch all the small part, like the fuel pump. The 4age 20v is harder because I would have to redo wiring, right now the gts gauges just plug straight into my car, with exception to the oil and volt gauges. I could put carbs on the 4age, make it a 4ag :p But carbs are harder to get now aren't they? and to get rid of the code I think umm the owners manual shows how to reset the code through the diagnostic port by using a small wire as a jumper.

Yea but its not workin properly it wont give me the code of wats wrong but yea you could get side draft carbs but heh... EFI is easyer to tune just get a stand alone ecu and u can adjust fuel/air mixtures and the spark timing.... and yea all sorts of problems with electronics so its rlly a matter of opinion....

EFi is easier than carbs. Less hassles....
Carb is old skool....
Take your pick, but if EFi was bad, why does most cars nowadays have EFi?

freakinbox · 11-10-2005, 01:48 PM

lol thats what I say to my dad :p. Unless you are good at tuning carbs efi seems the way to go. I could get dual carbs but tuning them is a bitch...

Flashmn · 11-10-2005, 03:22 PM

its not that hard, I tuned mine on the backroad near my house..

....Try carbs with a turbo.. bwahaha maan its crazyyy!

I vote EFI.

Better fuel economy.
More power.
Won't stall out on hills (more an issue in trucks)

The only good things about carbs is how if you're stuck somewhere with a blown fuel pump you can put a jerry can on your roof and put a hose to the carb and limp home

Oh yeah, and there's about 1/100 the wiring

Not necessarily more power from EFi.

burnt03 · 11-10-2005, 04:34 PM

I was thinking of the R series of engines, 22R and 22RE in particular. The HP numbers were 96 and 105hp (max) respectively.

There were some differences in the engines, but for the most part the 22RE is just a 22R with a fuel injection system.

freakinbox · 11-10-2005, 06:07 PM

the 4af has 90 hp, the 4afe has 110hp...

EFI is very simple if you learn it. the sensors themselves is only correlated with the fuel delivery in that the ecu is told different readings of the engine, air temp, o2, sometimes metal temp, coolant temp and 'gives the correct reading to the injectors'.

an injector is just a simple (non polar) solenoid. Provide a constant positive, then let the ecu hold the negative as long as it needs the injector to be open to deliver fuel.

Right, and I'm not claiming otherwise. However, its not as much the carbs as the manifold.

There are climate compensating carbs around, but in most cases the easiest method is to do a compromise jetting, unless you plan to change the jets every season. I havent had the need, tho, with the turbo its going to be alot easier, as I'm gonna have accurate pressure in the manifold all the time.

The thing is, that stock carb setup isnt the most efficient design, but neither is the EFi setup, however the EFi setup is better in the stock engines. Theres another thing too, cams on the carb version are "racier" than the EFi versions, which have cams for better emissions.
