Those guys are still talking big boost. I'm talking 4-6 psi from 3k up. The only way this differs from what comptech have already done is that I'm talking earlier boost.
No head gaskets, F-CONs, retards, or IC's need apply.

TD-05 doesn't = big boost. It's a tiny turbo 
Nothing like the large hair dryer's you see on Japanese Supra's with 1000ps of power.
Atlanta Motorsports did a B18A running 7psi. B18A has a stock compression ratio of 9.2:1. This managed to be "on-boost" at around 3000rpm, no lag, no piggy back computers, standard internals. But the intercooler was a must to stop detonation according to them.

Aus,
Maybe it would be beneficial for you to contact Speedcraft... I really don't think you can get away without an intercooler on this car. I don't know what whoever's law says but I've been pretty involved in turbocharging multiple S2000's now and I know that heat has been a serious issue.

is variable vane technology only for turbo diesels? I had an alfa and an audi turbo diesel with variable vane and it gives a great compromise between the quick pick up at low speed and efficiency at high speed without need for wastegate.

Ok, here's acouple of the ground rules for the basis of this project:
No head gaskets
No piggy backs
No opening the engine whatsoever
As for inter/aftercoolers. If it is required it will be done. If it is not, it won't. Simple as that!
Does the Comptech kit require an IC? No. So at full throttle we know we don't need an IC within the boost limits of the Comptech.
The question is, what happens at 5K with 6psi? Is an air/fuel mixture more likely to detonate at lower revs or higher revs?
I'll be using my car as the mule and running 6psi max. Testing will be done throughout the range and under all conditions. If the tests are successful I will release the kit in that form sans turbo. If you want an IC, no problem, just route the plumbing through an IC and back to the inlet manifold.
If the tests are unsuccessful and an IC is required it will also be developed and the kit released with it as well.
Higher boost? Head gaskets? Aftermarket ECU's? If you want to go that path you should have already bought the speedcraft.
