That .022" nitrous jet is good for roughly 70 Hp when you use four nozzles.  To
get the same flow out of one nozzle you need to double the diameter of the jet
(since the area is a function of the square of the diameter and two squared is
four).  I typically keep the same ratio of areas of the fuel to nitrous jets as
I go up, but this really depends on your fuel delivery system.  Usually an area
ratio of about 1.4 is the way to go - 22/24 is maybe a bit lean - if you're
using the NOS supplied vane type pump rated at 4.5 psi and 20GPH.  I'd usually
go 22/26.  Anyway, for one nozzle you could go 44/52 but you really need to
experiment since the dynamic fuel pressure of your system may vary with
increased flow depending upon your setup.

I use two nozzles with 31/37 jets on my blown alky KZ (using gasoline for the
nitrous system) and that combo works well with 18psi out of the blower.  The
last time I ran that combo it ran 7.83@175 mph in the quarter.

Good luck.

    if you use a "J" model head and you already have 8:1 pistons, your
compression will drop to low.  i used the same combo with a 1428cc motor last
year and it would never spool the turbo right, couldn't get no boost out of it.
i bought a new kit from mr. turbo last year with the hsr carb, that thing
carburates better than it has with four carbs.
    i also have a question for the group, has anyone ever ran N.O.S. with a low
boost setup (10-15psi)?  i would like to leave this thing set up for street use,
and use the nos once in a while at the track. what jet sizes are used with a
singe injector?  i used to have 22-24 in it set up without the turbo.  thanks.

  AHHHH Very nice Kwac.

(TURBOKING/1976KawasakiZ1turbo)TURBOKING/1976KawasakiZ1turbop://community.webtv.net/TURBOKING/1976KawasakiZ1turbo)

  What about those Cam motion Z3 cams ?
  I´m using std. cams,so the power fades after 7000 rpm (it`s a 1327cc),I have
tried Webcam #118, but they have way too much duration for my engine.
  After reading several catalogue`s,i decided that my next cams should be the
"Z3",so i`m very eager too hear what their like.I´m also planing to shop for a
Gpz 1100 topend  fitted with doubled sparkplugs (ohh,just have too renew my
lottery ticket).Anyone have tried that combination ?
