my friend told me that weber makes a throttle body w/injectors that will drop in in place of the stock carb is this true ? it sound kinda fishy to me

no thats not true but there is the possibility if you want to work at it.

The Quad ITB's by TWM is the closest Injection setup I can think of that is near bolt on. But you need a custom ECU to run those puppies.

:confused: what would make more power? dual weber carbs or a efi swap i know the dual carbs would be easier but what about the ponies? i want a little more than the 98 horse its got now.

question #2 how much of the smog (all the vacum lines and shit) can i take off. my friend told me that by reducing all of your smog you can free up some horse power?

Adapting the carb is easy... getting it tuned right is the hard part... and getting it tuned right will determin how much power you get from it. No one has bought the TBI set up so no one knows how much it can be tuned.

You'll need a header and a good exhaust setup to use the 350 or the other carbs / TBi's listed.

yeah, you take JDM B20A, remove the EFI intake manifold and make dual Weber setup. or you can drop A20 intake manifold, it will bolt right up and use Weber.
No matter what you do, you still going to end up with carburator.
If you want fuel injection, sell the car and get EFI version.

Both of these questions can be answered by browsing the F.A.Q. for the swap, and the carbeurator forum for tons of related info. Good Luck!

haha, all his questions can be answered by using F.A.Q., How To, or SEARCHING. sorry dude, but this is like the 5th or 6th dumb newbie questions you've asked and you even got smart and tried to say you were too good to search.

That is way beyond overkill dude. My brother has one of those on his 7.5 litre Big block. Good luck finding jets and rods small enough. You might as well go with the 2 Barrell Holly performance carb. But you will need a custom plate.

I knew they made those, I just forgot they used the same manifold as regular DCOES... sigh. :eek:

I'm all modified Keihin at the moment :bow:

I first saw the DCOE TBs on a Triumph Spitfire. The site is

would that tb fit on a carbed a20a1?

you need to modify the B16 DCOE manifold... then those TB's should work.. but then there still might be a little problem with the angle of the tb's but I don't think it's anything to worry about.

Yea, just have an angled manifold made.

The cool thing about those TBs is that Weber makes the whole package. Full ECU tuneable with a PC, complete fuel system and a complete spark system. I think I want to do that with my Integra.
