an ea81 carb?? I'll see about that, they both have hitachi chokes, appear to have the same bolt pattern, and are made in JAPAN

 

Only major preliminary differences is the float level window is 10x larger on the ford, and it uses a round air cleaner

 

 

 

 

It's possible. Let us know.

 

I do know that many Nissan pickup trucks used a larger Hitachi carb that bolts directly to a EA82 intake manifold, which in turn bolts directly to an EA81.

 

Throttle plate sizes are as follows:

EA71/EA81 = 26mm/30mm

EA82 = 28mm/32mm

Nissan Truck = 30mm/34mm

 

Also Mazda trucks used Nikki carbs that have similar mounting patterns, but I've never test fit one of these. Isuzu trucks use either the large Hitachi, or the Nikki, but I can't remember which.

 

I've always wanted to try one of these as a cheap alternative to a Weber, but I keep getting sidetracked with other projects.

ummmmm the EA-82 carb and the EA-81 carbs are different on the base one is longer than the other for bolt pattern and base wise

yeah ,but doesn't the manifold of an ea82 bolt right on the ea81.....?i think that is what he was getting at.i have been looking at carbs alot lately and it seems to me that there are alot of base patterns extremely similiar on the older nissans and toyotas.i even saw an early seventiescorona hatchback...yes i said corona hatchback.....with virtually the same base pattern and hitachi carb on it .even though something just wasn't right about the carb,weird secondary setup on it,i bet it would fit.

Right. The larger carbs only bolt up to EA82 intake manifolds because they both use the longer bolt pattern. But an EA82 manifold will bolt onto an EA81 (with a clever trick to get the disty to clear the EA82 thermostat housing).

no, it is more than just clearing the dist

 

you have to extend various wires, coolant temp, oil pressure, etc.

swap throttle cable bracket

remove and plug the bypass line that goes to the t-stat housing,

reroute bypass lines

remove the tab by said bypass line

remove metal on alt bracket

mix n' match emissions lines

use ea82 upper rad hose, air box and other tidbits

 

trust me, I've done it

 

I did NOT do anything to the dist.

Sorry man. I thought I was just sharing some info I've collected.

 

Thanks for the info on the manifold swap though. I was obviously misinformed.

BUMP! as some may be looking for the ea81 to ea82 swap

Actually, the EA-82's lower radiator hose works for the T-stat to EA-81 radiator hose with some trimming. It has the right curves in it. Done this twice now.

I think the hovercraft people with universial hovercraft plans that use a ea81 suggest using a ford escort distributer with regular points so to do away with the more complicated edi.

 

Some of the people who fly Subarus', I'm not sure if its the ea81, 82, or ej, use a 2 barrel rockchester for the increased demand for fuel flying.
