boost controller and boost gauge DIY

hi.. im Feckry Ag Ghani..

im planning for a boost controller and boost gauge DIY installation..

car and engine spec;

-toyota land cruiser bj60.
-converted to 1jzgte w/ stock twin turbo.
-old hks super blow off valve.
-K&N air filter.
-else, is stock..

here is some DIY article..
due to bdget problem, i just bought these cheap stuff..

jasma boost controller;

boost gauge;

silicon and fuel hose;

first.. lets prepare the boost controller first..

seal all thread w/ this PTFF thread seal tape
u can find this at hardware's plumbing section..

thread seal tape;


make sure u seal all the connectors..
the wastegate, boost/vac, gauge connector.

now.. lets move on..
search for you turbo..
then, find the wastegate actuator hose..
like this,

the wastegate actuator hose;

to reach both the hose, i took the filter n the turbo cover off..
one hose on the right, & the other one, is back there where the arrow show..
sorry, my camera couldn't reach it..

i wont use the pressure hose from both turbos for boost/vacuum signal..
therefore, i clog them using short hose with a bolt closing its end..
i'll find another source of boost/vacuum later..

the waste gate actuator;

as for the wastegate actuator valves, i combine both turbo's hose into one, using T connector..

i found a boost/vacuum signal which is the factory recirculate valve..
im not using this valve anymore bcoz i had another aftermarket valve..

factory recirculate valve;


Now, all hose connections of boost controller, boost gauge, wastegate actuator and boost/vacuum, done..
put back the turbo cover and air filter in..

move on to the boost gauge position..

i put it here;

then, find an electronic device that only turn on when the key is in acc mod..
therefore, i chose the clock..

here is the wire;

secure the connection with tape..
before u put back the dashboard in, make sure that the gauge works..

tighten all screws..
and u r done..

u need to make a few run to adjust the boost controller to achieve ur desired boost pressure..
as for me, i run 0.9 bar = 13 psi aproximately..
bcoz, 1jz-gte's ecu had a fuel cut which cut the fuel when then boost reach 1.0 bar..
it is a failsafe procedure bcoz the twin ceramic ct12 turbo cant withstand the high pressure..
to increase the fuel cut level, u need the fuel cut defencer (FCD)..
but, i dont need it.. im not planning to increase the boost more than my turbos can handle..

thats all.. thanks for reading.. good luck..
