Toyota carb swap started

i just got my rebuilt carb. from Pulled the zuk carb off, the Toy carb fits perfect. I've got to cut a vaccuum channel into the zuk's thermal gasket. Which will have to be tomorrow,as I dont have anything to cut it out here at the house.

Re: Toyota carb swap started

The carb is for a 1978 Toyota Corolla with a 1.2 liter. All the hook-ups appear to be pretty simple, I'll post more on it's performance when finished.

Re: Toyota carb swap started

That's the Aisan carb that I read about from a guy in Missouri who has been running one for a couple of years now. I emailed him July of last year and asked him about it. It sounds like a good swap if it doesn't cost too much. <blockquote><font size=1>In reply to:</font><hr>

The Toyota/Aisan 28/28 is approximately the same total
size carburetor. The stock samurai carb is a 26/30 Hitachi.
The slightly larger primary helps improve the low end torque
of the little mill. It is a very simple install because they
have the same bolt pattern. You will need to port the stock
samurai thermal gasket to match the larger 28mm venturi.Also
there is a vacuum channel that needs to be cut. I used a mini
die grinder(Ryobi, Craftsman, ect)to make very quick work of it.
Use the Toyota gasketfor a pattern. I also installed my Aisan
with the float bowl facing the rear. On extreme hills it will
still idle perfectly. The carb is from a 78 Toyota Corolla with
a 1.2L engine. The jetting is nearly perfect for altitudes of
600 plus feet. I found that it ran a little better of idle at
4000 to 6000 feet. I haven't messed with the jetting but may
increase the primary jet one size larger. As for the over all
performance, it is by far better off road when mounted as
described. Having a hand choke is also nice. It acts as a hand
throttle up to 2400 RPM. The highway performance is unchanged.
I get about 3mpg better now, but my old carb was on its last
leg.Also you can still use the stock air cleaner after removing
the aligning tab and clearancing for the manual choke. You will
only use one vacuum line to the distributor and a vent hose to
the charcoal canister. I added a line to my egr valve even though
I have it blocked off for inspection purposes. I am also using a
1.5" high weber/K&N open element filter with an adapter plate, for
better breathing and to free up that fender for my twin Cadilac air
shock compressors. I have had mine on for a year (as of 07/99) and
am very happy with its performance. Hope this helps
