g'day again,
Does anyone have a Holley carby on their 3F petrol cruiser & know what size (number) jets it runs & how good is it on fuel? thanks in advance,

I don't have a Holley carbies and really don't like them because of their archaic nature. Just a suggestion here and I have been involved in this before.

It involves making and adapter plate to hold two carbies off the earlier Toyota Camry engines also some Holden Apollo had them too. These are beautiful carbies, well made, reliable, meter fuel exceptionally well and have two barrels and an automatic choke which works.

Because of the two smaller throats opening in a controlled fashion you have terrific low down control, torque and progression to higher speeds. The secondary throats will open when airflow is sufficient and it will get up an go.
These carbies gave fuel efficiency often better than the EFI models had so sholud work on yours. The combined action of the two will give more flow than a Holley.
The two Camry ones will allow the engine to rev well past the destruction of the engine though. One on a 2 litre Camry will easily rev to 6500, so two on yours will have ample up top as the total flow you require is far less. You may even get away with fitting one carby only as it will rev your engine to redline anyway, IF required,
A Holley will cause low down stumbling and hard to control torque.
I just don't understand why people follow the pack and think Holley, Harley, V8 Crummydore. The 3f does a good job, you don't want to down grade it with Yankee rubbish do you.
Americans pour fuel in to make it go, Japanese do it properly.

G'day Ross, thanks for your reply & opinion. I like yourself don't like a Holley carby - but it is the only carby available that you can get a wide range of jets. Personally if needles were available I would have a (or 2) SU carbys because of the variety of needles that were available, I used to have multiple complete sets when I was preparing cars for Bathurst etc., at the moment I am currently running (testing, metering) on my cruiser a single early Holden Stromberg, after a twin throat Weber carby from a unleaded XF falcon to compare results. From memory the only carby on a Camry was the 1.8, SV21 petrol engine - is this the one you mean? If I can find the partic's of the carby's of your choice I would like to include it in my tests. Taking into account average altitude @ temp. for these tests. Hence the question - does anyone have jet numbers for their daily drive? I already have 3 different sizes to compare! thanks for your interest! hoo roo

G'day aussiedingo
No not the 1.8L Camry, the 2 litre SV21 Camry and Oldhen Apollo models have these carbies. As I mentioned they will rev the 2 litre to over 7000rpm and that equates to 3500 in yours just with one carby. Old Fergie tractors had a small carby and intakes and pulled well for the engine size. The Camry carby should also perform well with the small throat used under most climbing and off road situations. The second throat only coming into play at higher flow rates.

With the camry carby I would think no alteration would be necessary as it will be working within its design range and no jetting or mods of any kind would be needed.
PS The Camry also has an enrichening device and accelerator pump which works properly, unlike the Holley.

Some early Mazda 626 had a single injector throttle body injection system, a very simple system and just bolts on like a carby. These would also be good, probably hard to find, an out of the way wreckers may have some.

Hey Ross what Mazda had TB EFI? This could be very useful for a project I am considering...

EA Falcon also had TB EFI but it doesn't work very well...

Ross M, love your reply. Puts a big grin on my face!

Do you know, would the same apply to an older 2F engine - 1978.

It has the original carby, and it works perfectly... But more power, that would be nice :)

I should have said, also.... any better economy would be awesome too!

The TB EFI was on Japanese import square body 626 models. If it was EFI and IMPORTED then it has the TB unit. I have only seen a few of these but not recently so can't advise where, very compact unit though.
A mate and I talked about the Ford TB unit and we both went thumbs down too.

I can't see why you couldn't use those carbie/s on a 2f. It would be also ok and genuine Toyota too.

Gday Mate I had a 60 series with 3F motor and always wanted to upgrade the standard carby, all people seemed to offer was a holley, and I new that would mean a loss of low down torque for top end power (I wanted it the other way around) and a big loss in economy.

I was going to suggest a webber from a falcon or 6 cylinder cortina. They were good carbies. Also the 2lt escort carby was a good one, but there was a cracka that the modified guys chased that was a factory fit on the V6 ford capri. Whilst the capri motor was only 3lt this carby is renowned for its tunablity. They are still available from a specialist ford wreckers or brand new from the UK. It may be worth some investigation as I believe this would be a reliable option.

If all else fails you could always go with triple 40mm side draught Webbers chocked down to suit. It would sound great, but may be a PITA to keep in tune. Try the LCOOL toyota forum if you get stuck, they guys over there would have come up with a tried and tested solution.

Regards
