from nz300zx.com a standard TT doesnt produce 300bhp even at the flywheel does it?

All these stage upgrade lists are always optimistic. Boost does'nt increase with exhausts and inductions kits like they do on some Turbo cars.

 

US Zed's are 300bhp

That's 'American' horsepower figures - everything is bigger over there, right ? ;)

makes bit more sence.. so to run 300bhp in the uk how mcuh in the way of mods are we talking..? induction, exhaust 13psi? 14psi? chip (obviously for fueling the extra boost) or more than that..?

Induction, exhaust, chip 13/14psi will usually see around the 340-370hp figure.

right, (we talking at the fly or rwhp here.. guessing fly..)
