    i m building a 4agze ae92 map ,ported head,match ported inlet ,270deg cams,got a t25g but now have upgraded to t28bb
    with the t28bb is it laggy and what rpm does it start to work

    the gze injectors start to lean out at 11-12psi with a turbo and std computer or at 160-170kw u can run the 13b turbo injectors which are 550cc just check the plug there are two types or 7m? injectors are 440cc and they fit

    GZE injectors shouldnt run out at 12psi. Im running 14 and could push it further. Making 160rwkw. With 440's it should push just under 200rwkw depending on the amount of boost you want to run. The T28bb should spool up as quick as the t25g.

    my 440's at 60odd psi of fuel pressure wich would flow close to 500 were nearly maxed out at just over 200kw

    anyone using standard 4age bottom end with a turbo? I'm setting mine up with wolf3dv4 and t25 from ca18det. been a bit busy and had to put it off recently though.

    T28 is the way to go. it may take a tiny bit longer to spool up than a T25 but it has a nice mid range and top end response.

    I had a stock AFM GZE with an S14 T28 non bb i picked up for $200. (the ceramic turbz don't get as hot as the ball bearing ones)
    7M injectors put in as ZE ones couldn't keep up.
    Stock ECU on 14PSI and had no boost spike ever. Just ran lean coz i never had i tuned properly so it went boom!!!

    A larger frount mount will make your car laggy as it has to compress so much air so go for a 450 instead of a 600.(use as little ic piping as you can aswell. i have under half a metre of piping for both ends!) i have a 600 and it never came on full boost till 5000 but it comes on real hard.

    before they popped a headgasket on the dyno :angry2: (spike to 28psi) mine was making 150kw at 4000rpm, they hadn't tuned past that yet...
