hi all

i have a 91 300zx tt wich i have converted to a manual,

i am currently running;
upgraded ecu (cant remeber which one now)
2.5 inch full system no cats,
greddy profec b boost controller (set to 15psi)
255 lph fuel pump,
blitz lm air filter,
hicas removed,
air-con removed,

what need to know is what sort of power will the std headgaskets be good for before upgrading as i have just purchased a pair of uk manual hybrided turbos and want to run approx 400 bhp.

i havnt put the car on a dyno as of yet, so not sure what im running at the moment.

any advice,hint, or tips would be very much appreciated

go easy on me im not made of money lol

cheers Ken
