Oh, i didn't know the 240 turbo engine came with a T-cam, that is quite the dissapointment,
it sounds like a miracle it worked for you, if you'd ask me the M and T cams are good for absolutely nothing
Their main power range is something like 1000-3000 RPM. And as far as i know noone uses that part of the rev range for anything that resembles racing, neither dragracing nor circuit. But pretty good for towing i assume
Maybe this will help:

Generally, the more you plan on revving, the more lift and duration you can have.
You probably know this but i might say something useful haha!
People say you need less duration and such when you have a turbo to take care of power loss in the lower range,
this is true for an everyday driver or perhaps a circuit racer, but when it comes to dragracing and you are going to let the clutch go at 8000RPM, you really have no need for lower end performance and you can go all out, both with turbo size and camshaft profile,
to get maximum performance. So you should weigh out the options and consider the type of racing you are going to do with the car.
I will look after a chart i have seen of where the most popular cams operate.
But yeah, generally an A-cam or maybe even more aggressive, H-cam perhaps will work well,
the best thing is to test a few to see which one is the best for your application!
