Hey everyone , just wondering if anyone has got some pointers on how to
Run independent throttle bodys on an a series.. Manifolds,which bodies to use. What injectors..I'll be using a wolf 4d to run it..
Thanks very much

I wanna run EFI hardware quad throttles, they mount onto a DCOE weber manifold, will probably run megasquirt injection and run what ever injectors similar sized EFI engines run.

Some people are running motorbike tbs, do a search, there is plenty of info on here about it.

Some bloke has a set of toyota 4ag throttles for sale at the moment.

there are many options, all comes down to your budget.

Gday guys, check www.efihardware.com out, a little pricey but in the end you get what you pay for.[quote]

If you want to make up your own manifold for motorbike quad throttle bodies you might be able to get a flange from Clyons, if he's got any left. He had some made up a while back. (Hopefully I'll use mine soon, just about got all the bits ready.)

I'm going mandrel bent mild steel 1 1/2" with CBR1000RR throttle bodies (around 44mm). Mine came with an airbox, original rubber flanges, trumpets, inner and outer injectors, throttle cable, plumbing etc for around $100-, it was a good buy (I think). The flanges taper down just under the 1 1/2" pipe so once I've made up the piping and flange plate for the throttle bodies I can port match it. Don't expect fast progress though (and hence pics), takes me for ever to get anything done. The 1 1/2" exhaust pipe is very close to the CSA of the a15 port.

There was a 1000 up for sale a while ago with a similar home built set up. Depends how much work you want to do yourself. If you have to pay for welding/ fabrication it would be cheaper to buy a commercial set up like efi hardware (for that you might save a quid if you can get a dual webber manifold secondhand).

Do a search on this site on quad throttle body, itb, motorbike carbs, webber side draft etc. There's a lot on this topic floating around.

I am going with the 20V 4AGE TB's (silvertop 43mm), will fabricate an alloy manifold, aiming for a semi-downdraft type setup.
Also going to be a very long term project, my aim is for Dat Nats at PI, I hope!

These are one set of mine (50mm)
