4age carbies ?

[aussyboyz]

thinkin about doin carbies on a 4age or even possibly a 7age. What do you Recommend im thinkin 45mm webers? also do you still need a ecu?

[shift_rook]

no ecu needed, need to modify the distributor i believe. couple of other things you need to do, have you tried searching?

[aussyboyz]

yeah man i had a bit of a skwizz couldnt find much

have no read it in full, but i think the info you need should be here

[aussyboyz]

cheers man

[Golberg]

Just warning you, that there is no legal way of doing this and having it streetable.

[The Enthusiast]

yea, think your right there is some emmissions laws i think

[Golberg]

Yeah, the car wont pass emissions requirements with carbies. The car must maintain all factory emissions equipment from the car which the engine came out of. This includes the EFI system.

But as with anything, if you know the right people you can get anything passed. Doesn't make it legal though.

[aussyboyz]

yeah might try get away with it for a little while :right:

[ke_70]

y would you put carbys on it?

[blair]

i got 40mm webbers. they aighhhhht.

[fatke]

hey man i did a 4age with 40mm webers and believe me its fukin awesome if u want to have a look look at members ride fatke the power is great and the induction is just crazy
if u want to ask me any questions just pm or call me on 0406613308

[aussyboyz]

cool man yeah im pretty keen to give em a go. are they easy to get tuned?

What if it's converted to EFI?

[Golberg]

:S

One does not convert a 4AGE to EFI. They come as EFI motors, as such are legal in a Sprinter or Corolla with the appropriate paperwork.

[PeakingDuck]

My bad mate, I meant the carbies adapted to a EFI intake...

[Golberg]

Still wont happen, the EFI system needs to be there and fully functioning for the car to be legal. So anything related to carbies etc just isn't going to be accepted.

In Victoria, any mods that affect emissions require an epa test and certificate. Regarding carbs, a modest tune would pass the test but it's not cheap and every failure requires you pay for another test. At around $1500 per test (i'm told by a vicroads approved engineer) it's not really feasible.

So, it is possible but $$$.

EDIT: What sort of car is it going in? Pre '76 there are no/very lax emissions rules so a carbed 4age in say, a ta22, ke20 etc is legal without testing.

[Golberg]

At least in NSW I have been told that modifying emissions related equipment is strictly forbidden. But perhaps its different in VIC.

[PeakingDuck]

$1500 per test? Wtf? :S

[Hen may possibly be a nut]

^^ Closed room test. Measures evaporative emmissions and so on too, not just exhaust pipe (from what I was told by a Vicroads approved engineer).

[fatke]

its not easy tuning carbs but once u do it it will go way harder than a efi 4age

[af300e]

I suppose they use it as a disincentive for people who want to bolt on hairdryers.

The engineer in topic had a customer who built a blown commodore V8 and wanted it legit. Spent a cool $10,000 on epa testing. :O

HAHAHA good one.

Oh, you're not joking? errmmm........

[rthy]

i guess the reason why carbs are still used is because of induction, thus:

Carbs do go way harder than EFI. After back to back testing I actually measured it (with a Rockwell hardness tester incidentally) as carbs going HEAPS harder than EFI.

Wats the big deal. Lots of things people do on this site dont pass road worthy. Also converting to carbs wont make a huge different to emissions if they are tuned correctly.

I have converted my 4AG to Mikuni 44's, aussy and it's unreal the induction, nothing like sidies. I have both injection and carbed 4AG'd vehicles and carbs go harder.

Just do it mate. You can use the 4AC loom, assuming you have something with a 4AC in it, however you need to get another distributor with an advance mechanism. Custom built ones are your easiest bet, Scorcher do em. Alternatively you can run a linkage that you can run the TPS off and use the standard ECU to run ignition only if you have a 4AGE loom. There is also the MSD route

[aussyboyz]

yeah man im pretty set on it.

[aussyboyz]

whats the best fuel set up 2 dude?

[4A-GE Power]

As in pressure? Mikunis can handle bout 5 PSI but you'd want to run about 3. Webers are lower. Fuel height is critical, so make sure it is set correctly. A Facet low pressure high volume pump is a good option, then run it through a reg and filter in either order doesn't really matter, probably filter first. Let me know if you need any help with them mate

[Hen may possibly be a nut]

From advice I got a while back (from a couple of carbie tuners), the square Facet pumps are dodgy, while the round Facet pumps are a lot better.

[4A-GE Power]

Yeh square ones are shit, more often than not they are copies and they are loud as fuck. Cylindrical Universal Facet pump is the way to go
