Has anyone ever seen or heard of anyone converting a 4age to run twin carbs instead?

 

Can it be done?

How hard would it be?

 

Cheers - Andrew :lolcry:

Besides the tuning capabilities, why else would you get twin carbs over injection?

I have a pair of twins already and wondering if it would be worthwhile putting them on a 4age for simplification of conversion (and i reckon it would sound pretty damn sweet too lol)

Yeah it's been done. Redline make a manifold to suit.

Part # 12-23 & 12-22 (From memory) depending on big port or small port.

Been done a fair few times, here's one on our club.

 

Trevs twin carb AE71

wouldn't it be illegal?

ive got one

 

carbs are alot more responsive then the efi

 

and you don't need to worry about ecu etc.

Thats what i thought might happen

 

Was it hard to set up?

although they do need constant tuning when seasons change

If you're smart about the seasonal thing, you can probably get it dialled so you just swap jets over.

 

Mate of mine used to drag race a triple carb 6. He had a set of jets for heathcote and a set of jets for calder (Altitude difference!)

what kind of performance do you get, compared to EFI?

 

anyone heard of this being done on a 4AGZE?

If they're set up properly, you NEVER have to touch them.

 

Had numerous sets of twins. Set and forget.

I do actually have twins running on my 4k at the moment (see my signature)

I spent a grand getting them rebuilt and tuned and they run sweeeeet

 

But my potential plan is to rejet and put these carbs on a 4age for several reasons

 

1. Already spent the coin rebuilding and setting them up

2. More power with the 4a of course

3. Something different

4. Don't need an ecu

5. Would sound farken awesome

6. Tunability

 

As Jono pointed out though, I think i had better make sure that i will be able to register it like this :P

Running twin carbs on a motor that was originally EFI would most likely make it illegal from an emissions perspective. Probably best to talk to an engineer.

Thats what Jono said to me this arvo aswell so i'll definatly be doing that before i go too far

 

Tis a shame if i can't do it though, I reckon it would be a beast of an engine
