[R33GTR]

95 r33 gtr in cairns (leigh holman wants $300+ to do it)

has anyone made a step by step installation guide for boost controller?

ive been told its pretty easy to do but I really have no idea how :/ i have instructions that came with it, but still have no idea.

HELP!!

[Pedro01]

plug it in


hold down the bottom button

then set to open loop

push bottom button again


next is your duty cycle (boost) that you will have to set by driving and testing boost they say check it on 10 then do another run on 20 and see how much it goes up by (ie if it goes up by 3 psi ,then every 10 should = 3psi )

push bottom button again

this menu is the Gain ie how fast it comes on boost ,be careful of this one as it will make your boost spike and a rule of thumb is it should not be higher then then the duty cycle


then that is it for the basics


if you wanna learn more ( scramble ,different boost settings for gear changes etc ) go to their website

Ive set up the scramble because my car spins 1st and second on 18psi so i try to get it to launch on 12-14psi then after 2nd gear ill hit scramble and that goes to 18 psi for 3rd/4th gear

but its not something ive done alot of so it would be hard for me to remember what i did to change the settings

[Pedro01]

oh and if your boost is very unstable


set it to closed loop


but you will have to set all the gains and duties up again

I am sayin I dont even know what pipes to run through to the solenoid, its twin turbo so do I have to run more pipes than install diagram? do I have internal or external wastgate? was hopeing someone had done it before......

I havent even thought about the setup of the boost, Ive got to get the thing in my car first

[starlet666]

if u dont know what ur doing.... find someone to actually show u or just pay the money.... blowing up a rb26 is never fun *looks at hirpm boostjunkie*

[R33GTR]

yea I really want to learn, I mean I pretty much know 'what to do' but just need to know a few things since its a twin turbo.


't' off the pipe from the soleniod into both turbo's actuators
use the pressure port already on the intake manifold and send it to the new solenoid & the controller (again 't' the pipe) (old solenoid now has nothing connected anymore)

what should I use as positive connection? battery is in boot and instructions say use fused power source only live when ignition is set to 'on'

is this correct so far?? anyone?

[200sxxx]

I am getting power fromthe cigarette lighter
Doesnt realy matter where you get 12 volts from, whatever is conveniant and turns on with ignition

There would be plenty of pictures on SAU that shows you how/where to put the vacumn hoses

And you wont blow the engine...lol, when setting boost just use a bit of throttle control so it doesnt go over your desired level

Im not to clued up on 33 gtr turbos but they may be ceramic wheeled(find this out) so you dont want to take it to high

what i sujjest is go to greddy.com and they should have downloadable full diagram to fitt there boost controllers and just do the same for the gizzmo !!!!

[RX7BREEZE]

greddy has pics to if you get confused!!!

[hirpm boostjunky]

on the drivers side strut tower there will be the factory solenoid with a line goin in and out, one of those lines will have a white line around it, this is the factory restrictor put in place

you need to use the 2 vacume lines that go to that solenoid, but you need to work out which one goes to the actuators and which one goes to the boost messure source

at a guess is this the white r33 gtr getting around town with r34 gtr rims i saw the other week...

[R33GTR]

Yea bud, thats me, got the thing set up and the bloddy solenoid was faulty!!! ARRgh sent to gizzmo for repair/replace

does anyone know what standard boost for 33gtr is? ive read 7psi, but with the EBC connected and vac hoses back to standard it shows boost peak 10psi...... its a little dissapointing thinking that i was going to go from 7 to 12 .... really only going 10 to 12 :/


Its really easy to set up once you know where hoses have to go.

[NJA82]

Standard boost is 0.7 bar ( 10 psi )

[Mazdabater]

Out of curiosity are you putting it in and upping the boost and thats it?

[R33GTR]

you asking about gain/duty cycle etc or what mods I am doing overall?

[Mazdabater]

No i mean are you just upping the boost without changing anything else?

[R33GTR]

so far ive got

twin pods & exhaust

as money allows, i will add water injection, cam gears, dump pipes and possibly intercooler (hard pipes)

water injection is waste of time and money

cam gears will help.. but you'll need a computer to get the most out of them

Dump pipes, be warned it'll take you at least 10-15 hours to swap them over depending on how mechanically minded you are, your better off just doin front pipe, replace the complience cat and cat back exhaust. leave the dump pipes untill you change turbos.

hard pipe kit, this will depend on the condition of your standard items, if your stock rubber pipes are crap and perished go for it, but theres no need to change them if there fine.

[R33GTR]

well depending on who you talk to water injection does have its advantages for very little money.

as far as computer I think i will just buy nistune.

hard pipes come with intercooler (one i am looking at)

any suggestions on frontpipe/exhaust?

[Mazdabater]

I would suggest taking your car to a mechanic before you up the boost myself. If your just upping the boost without adjusting the fuel maps you could be asking for trouble. I know most ppl reckon a couple of psi is nothing, but thats a load of crap your gonna be leaning out your car. I would personally put the exhaust/dump in with the computer as if you don't your going to need a fuel cut defender. Water injection is only really a good thing if your running high boost levels, or have a really ineffecient intercooler, and is also going to be a pain in the ass to have to keep topping up. I personally would steer clear of it on a street car.]

But honestly not meaning to sound like an ass, i think you need to do some more research, you don't seem to have put any thought into these mods. Your best off finding a tuner and seeing what they reccomend, or doing some research on the skyline forums before you go emptying out your wallet.
