giant:
i am not familiar with the layout of the 7k manifold other than the fact that it is 2-piece and yes it will bolt on (all K stuff shares the same head bolt pattern), however they are expensive to buy new, and as difficult to find as the 4KE manifold used. fabricating a manifold is not a great concern to me as i can do this quite cheaply... what i really mean is if i have to fabricate 1/2 a manifold i might as well make the whole thing up exactly how i want it... hope that makes sense!

the 4KE manifolds are quite poor, the only thing they have going for them is they bolt on but i think i will end up fabricating something of my own.
which leads me to this - i think i will get hold of the 20v setup, mount them vertically where you would usually find a carby on a K series and build a plenum over the top of them. would mean a custom manifold + plenum but it really shouldnt be that much work, and would get the throttle bodies up where i would like them (ie away from the strut tower). conversely i could build a 180degree manifold and sit the throttle bodies over the top of the motor but i think then the fuel may have to travel too far in the piping... ???
i am quite keen on the 20v idea as these throttle bodies have come down a lot in price and shoud flow very well if i ever go totally mental. i have been told i can realistically aim for about 200hp at the wheels witht he setup i have planned....
