    Who's got Courtenay stage 5 (GT28 & engine internals etc) on a Z20LET?

    There must be someone on here by now but I can't find any threads? (Links welcome)

    Interested in roughly how much is costs from start to finish and how much wow factor do you get with 350+ bhp and about the same in torque!!

    (Then the borin stuff like reliability, mpg etc).

    Thanks

    Or just scrap them.

    Get Nortech to make you a manifold up. James can also do you the IC piping and get the Turbo. Source some injectors... Maybe get bigger AFM.

    Go somewhere who can do proper live mapping.

    310bhp on standard internals for alot cheaper id suspect

    If you really want to go over 330hp.

    Why change something if its not VITAL.

    Nope, but shall be.

    Jonny from Sheffield did. Untill he upgraded further. He ran 311.8 WHP for nearly 1yr on standard rods and pistons. He put in ARP Rod bolts though.

    how many miles did he do in that year and does he drive like a 70 year old!

    If you wanting obove 300bhp then its best to upgrated the internals to make everything nice and safe!
