Vini,

A couple of people have installed this kit and liked it. The designer has gone to a lot of trouble testing it out and make it user friendly. I also believe that it comes with support to help you install it and get it running. I plan to get one and use it on one of our Corvair Ultravans.

(2) Our 1963 Rampside (Sold 2014) and 1967 Ultravan #256 at Upper Canada Valley car show in 2009.
(UV256 aak Itchy Feet II - corvair power plant came out 2012 - plans with donor for a GM 3.8L FWD conversion, as a gas pusher, in the back of UV256)
(3 & 4) Are some of our 11 Corvair parts cars - to help keep our stuff on the road - hopefully as long as we live. ;-)
(5) Is one of our Wayne 100 boats (Corvair powered)
(6) Nov 14, 2012 Ultravans #362 and #512 arrived. We are getting closer to our goal of having an Ultravan museum.
We now own; UV248, UV256, UV362, UV512, and UV520 will hopefully be here July 2013.
(7) I saved Ultravan #231 from the scarp yard this year. It arrived May 9, 2013 and I plan to flip this one with a mid-engine Subaru power plant.

Thanks for the comments davemotohead , Ottawacorvairguy

Sounds like it could be the way forward for me hoping to get summer out of carb as crack not gone all the way through so when I am state side in September can get it shipped to hotel and bring it home in luggage.

Many people remove the secondary carbs completely from a 140, some argue it's better without, may be an option for the summer at least.

its a good kit.......but w/only 2 throttle body youll choke your 140 for air @ high rpm. heres some info.

if your not running your 140 hard.......youll wont notice this loss of power @ high rpm.

> and is it worth the money being in the UK will also have shipping cost
> and duty

cant say if its worth the money..........only you can know that.

it would be worth the money to replace your secondary carb w/the hair line crack & rebuild the carbs if they are worn out.

if your carb linkage is worn out.........most are now........it would be worth the money to replace it with some nice linkage.....like this.

efi is better than carbs.....thats a fact. but that doesnt mean that the carbs wont work good for you when they are rebuilt & working like the factory designed.

lots of vairs are running carbs & everything is fine.

how much will it cost to get the efi..........shipping & duty? how much will it cost to get a secondary carb & rebuild your carbs if they need it?

only you can say if its worth the cost because everyone has a different idea of what something is worth.

Ray Sedman of American Pi sells an EZEFI kit that converts the lower section of the carbs to EFI. You can buy four of the units and have all four acting as primaries. With the EFI, you won't get too much or too little fuel. All EFI systems will want a lot more fuel pressure so factor in a new fuel pump and filter. As the name implies. this is an easy way to accomplish a high performance EFI system. Ray can talk you through everything you will need.

Life is so boring after thatsmiling smiley Once you crack those secondaries its to much fun to ever turn back. I do have one secondary that has almost caused me to take a hammer to the whole car though. Love hate relationship really. J3M would be super pissed to know I drove 44 miles back and forth to work for the past 2 weeks. Hell I even had points in! I know, It's nuts what a lunatic I am. I do like Browns EFI though.

Greetings from the states, I plan on installing the kit from Clark's on my 140 auto since this will become my daily driver. If I get everything done before you return to the states your welcome to contact me and ask how it's doing, I've seen almost as hot a discussion on the topic of 140 with just the 2 TBs flowing not as much, the same, and more than all four carbs WOT as that of which motor oil is best haha. I'm going to guess that at worst you will not notice any difference in performance due to the perfect tune of both fuel to air and ignition even if it flows a bit less. But to me flawless starting and running everytime no matter the weather or temp of the engine and the lack of fiddling with carps, points, cap rotor, to me thats a pretty good selling point. Just my 2 cents worth.

..how often are you going to run the engine at WOT where the extra fueling volume of carbs would make any major difference?

I will race my 140 with 4 carbs against a 140 w/2 carbs or with EFI on 2 ports and we will see who wins? 140 engines like to rev and run especially good with a good cam and all 4 carb ports, Why choke off the bigger heads with not enough flow at higher RPM? If I was going to do a 140 I would go with American PI set up as well, Better to have too much than not enough, if your not going to get full use out of a 140 get a 95 with A/C and 4 doors. smoking smiley

I don't want to take a sale from Tedd, but there might be an alternative.

How about a FiTech TBI on a 4Bbl 140 intake?

A company that sells aircooled VW stuff is taking the FiTech system and reprogramming it to run on anything from 90HP NA to 600HP Turbo.

[www.lowbugget.com]
Their NA kit costs $1400.

You might be able to purchase the 400HP unit from FiTech (~$800 + fuel plumbing) and bolt it to the 4Bbl intake without reprogramming.

This would allow you to use all of the intake ports, and the fuel atomization from the injectors may reduce the throttle lag and runner freezing that the 4Bbl intake with a carb is notorious for.

So, you have three system to consider:

Clarks - A proven system. Tedd mentioned in another post that he is working on a system specifically for the 140

American Pi - A proven system that would give the 140 back its Oomph.

FiTech - Currently an unproven system for the 140, but has potential.


Just my thoughts.

w/the TBI on a 4Bbl 140 intake youll have the same runner freezing that the 4Bbl intake with a carb is notorious for.

It is proven that EFI will not make your engine run any faster. But it will improve the starting, smoother idle, just like a modern car. I believe that the carbs on the corvair were it's downfall. Just look how many post on this site are about problems with the carbs. The old flathead fords that I used to drive never had to do a carb adjustment, just start and go, not to fast but never had to worry about the carb. I know I'll get flak about the corvair carb being so good . Not all of us are DAVEMOTOHEADS that have the knowledge to do the special tweeks to make them somewhat reliable. Yes EFI is not the future, it's been around at least 30 years. There's nothing wrong with living in the passed but there's also looking for better ways to solve your problems. flame on gents.

While EFI improves drivability under nearly all conditions, it doesn't increase power (unless it somehow can increase flow).

To me the biggest problems with the carbs, other than 50+ years of wear on them and the linkage, is owners who won't leave well enough alone. Same thing with valve adjustments. How many times do we see someone pick up a nice running Corvair and the top of their to-do list is a valve adjustment? Why? If it is running good, leave it alone.

Once everything is in proper working order, leave it alone. Drive and enjoy!
