he's upgrading mine when i get it shipped. i reached him through email. i could never get him on the phone. viewed his profile on here and clicked the 'send member an email' link.
from the research i've done, people say that the upgraded turbo at 5 psi feels like the stock turbo at 10 psi. he basically puts gt28 internals in, bores out the output side of the turbo, ceramic coats it...and i believe he p&p's the downpipe and exhaust mani.
2-3 weeks...you can buy my stock set-up...$350 for the exhaust mani, turbo and downpipe...then you don't have to worry about down time....then once you get it back from nick, sell your stock stuff for $500...my turbo needs to be rebuilt anyway.
