Andrew,
Yep the nizpro 1600 is pretty sick. I saw it in action at Sandown (John
Mott) last year. It does 1min 22s hand timed and Anthony told me it pulls
270km up the hill on the back straight.
Phil Morris has more secrets than just his Z cam. At the last state round at
Phillip Island he kicked everyone out of the pit garage and closed the doors
after he jacked the car up. His car is probably just as fast as anthony's. I
timed 1min 48secs around the island for Phil.
Regards
Trev

Subject: Re: Throttle Body size??????
Steve,
According to an old article in zoom the stock motor was rerung and new
bearings.The
head was ported with the emphasis being on the exhaust ports and 125lb valve
springs
used.The inlet manifold was ported and RB30 throttle body used.Bosch 351
injectors,280 thou lift cam,stainless tubular extractors.The turbo was a t04
v-trim
comp wheel with a o-trim tubine wheel and .63 housing.A huge modified
kenworth truck
intercooler,scorcher ignition and motec comp.This gave them 327hp using
17psi.
Wanting more hp they then built a serious motor.Nizmo competition block with
nizpro
w-rings and bolt holes machined to suit GTR skyline head bolts(12mm).Nizmo 8
bolt
forged steel race crankshaft with steel light weight flywheel.Nizmo race
conrods
with forged pistons with ceramic coated tops and teflon coated skirts.A
90psi spring
for the oil pump,baffled 6 litre sump with windage tray.Inconnel exhaust
valves,
heavier valve springs,Phil Morris vernier cam gear and a secret cam designed
by Phil
Morris with less ramp speed to allow for higher rpm.The turbo is also a
secret but
is similar to the previous one only with a larger comp wheel and probably a
larger
turbine wheel and housing.This combo got 418 hp @ 7800rpm at 24psi.
