My two cents worth and a question
I have kind of the same dilema, nord, TS or 2.5V6(some guys have made this conversion look really special and I am sure this is a major step up from the twin spark in terms of torque). As I have recently read a few threads on originality being important I thought I had decide on keeping the Nord but this thread has throw that all into chaos again. (Have a 100% original 73 GTV in need of a total refresh)
It seems from comments that the key to driveability is the 3d mapped ingition set up, is this the case ????
I my opinion that is a big part of it as the dizzy does not have much scope for modification (Nothing compared to 3d mapping as I had on my evo6, but that was fuel as well) so my current plan is to use a megasquirt with throttle bodies (Actaully modify a set of dellortos so it looks period correct) and put a crank sensor on ( Machine teeth into the pulley on the front of the engine and use a standard induction sensor) so the dizzy can be totally removed (Of course airflow sensor and throttle position sensor etc would need to be added)
I found a company in Australia that makes Hbeam rods and can get me custom JE pistons and was plannning to up the capacity a little so would be a true 2 litre engine so this should help give a little more power. And the heads would be ported a little, not to much as I dont want to risk punching through to the water jacket - so I guess this will be the limiting factor in the engine. Also use some highlift cams.
This in my opinion should make good relaible power with great diveability - when I finally get around to building it I will let you know ( but at the moment that is quite a way off)
