Fantastic car You have there!!
How many hours spent so far........!!?
Anyways if you have any ideas on how to make good torque witouth chasing high BHP i am opened to suggestions.
As i cannot find any pictures of headwork I will suggest the following:
I used to have an Integrale 8V cat - now in my brothers hands. During my time I took off the head to have a look and it was really not the best in finish and dimensions.....at least compared to what I had seen before (124s/Ritmo Abarths)
Take out the guides and clean up the ports properly and enlarge a little - install a set of bronce guides (check this site). Do the valves, seats and combustion chambers and put it back together and change the probably warped exhaust valves.
The head work will take a some time, I struggled especially with the combustion chambers, but it was worth the effort!!
With a fuel pressure raised approx 0.3 bar it now went very much better - it really flied!!
I have not experienced such a difference in any car before - the gains were enormous in response and power.
If You havent ported before now is the time - You cannot go very wrong on an Integrale 8v head in my opinion - they are easly made better....!!
Take a look at the pics underneath - the Integrale is a fantastic car, but the heads I have seen are not very nicely finished.... and that makes them easy to improve:-)!!!
Regarding remap/dyno I have no clue - If allowed I would convert to blow thru carbs any day........
Combustion chambers finished
Finished exhaust port
Intake port and chamber before....... not the best looking I should dare say
Flakes of aluminium around the valve guides among other things.....
Valve seat vs head mismatch machining.....
