hi guys
i thought it was time i started posting on here, been a member for long enough !
since 2004 , seen alot of progress and interesting projects on these forums
big shout out to you all for making it the best 1uz forums in the world
and of course lex for keeping it going !
i want to share with you guys my experiences with 1uz mods that i have done on my supra
and the power figures i have got along my journey ( will not talk about cost )
a friend did post on here some time ago about my car ,
thought its time for a update
project : 1983 mk2 supra , re-power her with a 1uz and supercharged it
we finished the car in late 2005
stage 1 upgrades : ( first build )
engine : stock internals ( not opened )
modified manifold for the supercharger
Eaton m90 supercharger ( smaller pulley) 5.9 psi
water to air intercooler, using a subaru radiator and pump
standard throttle body
7mgteu injectors
ecu : linkplus
fuel : modified fuel rails, malpassi fuel reg , bosch 044 pump , upgraded fuel lines from the tank
exhaust: 1’ 5/8 headers , running two , 2 ‘1/2 pipes joining together for 10’ then exiting the side of the car
transmission : A340 , internally modified ( taken the smooth changing out ) , now a manual changer , with the help of mates standard alone circuit board made for the trans its good
power : 273 rwhp / 204 kws @ wheels , 5.9psi
stage 2 upgrade :
camshafts : kelford cams spec supercharged cams
heads : ported and flowed / decompressed
ecu : upgraded ignigter packs running separate coils ( ditched the factory dissy’s)
leads : upgraded the coil leads to 8 mm
re-tuned power : 328 rwhp / 245 kws @ wheels , 4.9psi
stage 3 upgrade ; ( current setup )
supercharger : install the eaton bad boy m112
intake : change the intake , bigger piping / 90mm throttle body
re-tuned power : 410 rwhp / 305 kws , torque 950 nm @ wheels , 10 - 11 psi
stage 4 : next planned mission ( next trip back to new zealand )
because of what we have done , driving it , it simply starts overheating under boost
we thought there may have been a blown head gasket or something
so last time the heads were removed and inspected , no problems that were visible
the thermostat was replaced as well as the org radiator taken apart and cleaned properly
from that we can only assume,
the main radiator can no longer handle it, need to upgrade to a nice big one
intake temps are far too high , 90 - 100 deg celsius / 194 - 212 fahrenheit
the water to air intercooler is no longer doing its job ,
will replace the water to air, subaru pump with a toyota GT4 water pump ( its a bit bigger )
we may have to install water/meth injection to solve the problems
if we can sort these small issues out , and get air intake temps down ,
we should produce some more numbers on the dyno
hopefully making it reliable and more fun to drive
I have been based in Nagoya , Japan for the last 4 years , the car is parked up in my garage in New Zealand , next time we go back to nz , hopefully we will sort these issues out
big thanks goes out to the lads at http://dynopower.co.nz/ for their help and tuning

all the boyz that have helped me and kept me focused on my ride over the years
pics of my supra and video of the dyno runs can be viewed on our gallery http://gallery.me.com/hayatonka#100065&view=grid&bgcolor=black&sel=34
