Given that even a SR20DET that has been rebuilt with minor work running around 20psi with a you beaut roller bearing turbo that smashes S14 CB71C gearboxs with ease and runs a 12 second 1/4 on street tyres has only has 208RWKW the expectation or the 180RWKW may be on the high side reguardless of how much dosh you throw at it. At the flywheel I could believe it is achievable. Turbo setups are difficult to get right at the best of times. Raving on about unrealistic figures is best left to the boys who are old enough to drink and talk crap at the pub.
