Boost Upgrade - R32 Gtr

[BAILED]

Hey

Im wondering how to remove the restrictor on the R32 GTR's so that i can run around 15psi. Ive searched but dident come across much. Ive checked out the pipe on my car with the yellow band around it but dident find any metal restrictor in it ? So how do you do it and where is it ?

Also is it safe to run 15psi ? I dont often drive my car so if i run 15psi and boost it every now and then should that be ok for the motor ?

Thanks

How far down is the restrictor ? someone said it was ment to be under the yellow band.

Anyone ?

i ran 1bar (14.7psi) hapily on stock 15yo engine...

its on the intake side of the enigne, right after the factory boost solenoid, bout 3-4inches down from the solenoid, either cut it out or pull it out with a paperclip...squeeze the pipe to find it...

i noticed that the boost will fluctuate a fair bit tho, better to leave that in, and then put a boost controller on the wastegate actuators, so you still have ur min boost setting if necessary and more if u wind it in just an idea...plus boost comes on harder with a controller

hey ive tryed doing that. its the PCM value your talking about isent it ? and the tube with the little yellow making on it that runs down towards the botton of the motor. there is nothing in there ? no restrictor ? but my car makes the stock boost....

The restrictor should be at the same spot (or near enough on) as the yellow band. Easiest way is to jus cut the hose where the restrictor is as its very hard to just hook out of there

Whats it ment to look like ? I have run a UHF car arial into the pipe and its not getting blocked by anything. I can feel a indent at the point where the arial crosses the yellow part but definatly no change in the size of the gap. weird...

you'll be able to feel it by hand.

being its a solid item.

Just squeeze the hose till you find it

hmm, the hole in the restrictor is like 1-2mm, so a uhf antenna should be stopped by it, maybe its not in there, i know that there is a manifold pressure bleed into the boost line at the back of the engine that stops it overboosting if the PCM valve fails, maybe thats the drama? still i took mine out and boosted 1bar :S not sure...

R31Nismoid - i squezed the hole pritty much all the way down to the bottom of the engine and no change.

oRiCLe - yeh im not sure eaither because yeh everyone else just takes that out and gets the 1.0 bar. this one has me stumped.... unless there is a boost controller somwhere on the car i dont know about while it was in japan ?

Its looks like all my vacuum lines have been changed. Where would I find the restrictor in the vacuum lines?? Is there just one I need to take out?? Does it come from the actuator. Please help.
