Thanks Des and Andrew for the replies,
I have been doing some more reading and I agree that the 4AG would be the best option as it will be a dropin fit. I do not believe in reinventing the wheel and would prefer the drop in solution.
I was looking at the T25 turbo manifold for the 4ag, as I would rather turbo than SC as the SC uses up power to run itself, when the turbo just makes power.
I know that lag is a result, but if you keep them on song, its all good. I might alo look at Motec with some antilag to overcome this issue. I must have forced induction as I just love boost :D
I would like to get a W58, but cannot find out if the trans tunnel needs to be modified, I would rather not have to worry about this. Does anyone know for sure if they fit ?
I will also be looking at a Hilux G diff with a 2 way locker and a rear disc conversion, as I want a very strong driveline.
I will investigate a good brake option as I believe that Cressida brakes fit. I was planning to go Coilovers all round to allow some flexability to the setup.
I do not plan to run in any "class" of racing, only club supersprints. I figure it will be in modified under 3lt class for these events. As for drifting, I will do the odd ID drift days as the F6 is a bit too heavy to throw around drifting.
Here is a pic from the last Eastern Creek drift day:
