if you can get a complete Ea81 twin carb motor that has the re-worked factory heads, the difference is imediate compared to an single carb engine.

I had one bolted to a 3.9 ratio dual range box it was unstoppable.

Grab it while its available.

whats the power difference like and it has had exstensive work done to it. it was once in an offroad racing brumby was a full custom thing looks awsome but has sat for a few years now the car its in suffered a smash in the rear n was never repaired apparently goes like a cut snake tho. since the engine has sat for so long it will need to be rebuilt wont it

and he was also talking about seeing if i wanted to put the 3.9 ratio in aswell with lsds and dual range

Go for it! The power is a quoted almost double that of a standard ea81, if it is a true dual carbie (ie dual port heads as well). I was lead to believe the dual carbie was quoted at 120hp verses 60-65hp for a standard!
Bianca has the dual port heads and wild cam on her with a Weber and pulls likes a cut snack... Unbelieveable difference to standard EA81.

Also if he has a second dual carbie motor, i call shoot gun on the carbie set up!

Or even the mainfold, i am thinking Dual Webers..... Hmmmmm

It is where my Bianca original came from 10 years Back now! He had a huge lifted Yellow Brumby with twin carbie's, etc set up for the rally circuit and back yard full of wrecks Brumby and shed full of half cuts.

He use to own Subaru Nambour off memory.

A friend of mine is currently rebuilding one of the twin carby/twin port head engines for me. Unfortunately there have been unforeseen circumstances but I will be posting here once all is good to go. As the engine is in Brisbane and I now reside in Sydney I am unable to get more involved.
