My mate owns one and he has put a boost gauge in the car and because we have no manual for the car we can't figure out what is wrong, i think it's that he hasn't disconnected the old guage however he informs me that it is electronic (meaning that there is a pressure sensor inside the pipe) not mechanical. I was wondering if anyone can back this up as i don't wanna pull it off then have to put it back on.

I know it's not working properly as the original is in mmHg and this in psi and I've work the calculations out and his new guage is showning 5 to 6 psi when it should be showning 10psi.

Any help or advice would be great

1. the old guage being connected dosnt matter.. which is electronic yes..

2. what kind of gauge is the new one? mech or electronic??

i will be able to help after i know that.

ok well if your running a boost line into the cab i beleive the best place to take it from was underneath the top mount intercooler.

there is a rubber line that goes to a metal part and then out rubber again under the cooler. you can t peice it there and if all goes well it should be sweet.

other than that thats all i can say given the limited info..

and thats how i threw a mech guage on mine while testing it out.

but and a big but here.. be sure to have all the lines around that area firmly put back on. as when you undo any line around there and its leaking your running max boost.. it sure is fun but the poor little fuel pump cant keep up..

hope that helps you out..

i am a wee bit drunk but thats how i had it on my r back in the day

have set it up with a t peice joining it together i went over it yesterday can't find a problem so i think i'm going to have to take a look at the guage

why not t it in with the fuel pressure regulator line like most cars?

what brand gauge is it?

[Beer Baron]

i would use neither. the line mashrock suggested is the pressure feed for the wastegate actuator, so if something goes wrong you will get unlimited boost. the fuel reg line i wouldnt touch either, as it's the pressure feed for the fuel reg. and if it stuffs up, no fuel pressure above the base 38psi.

find the map sensor. it's a little black box bolted to he inner guard. it has a vac line and and elec line going to it. that is the sensor for the stock gauge. tee into the vac line going to that. best way to do it.

[NeoGTR34]

Have just moved it to the vac line and still the same thing reading a lower psi than it should be. I'm over it can't figure it out might have to take it to the mechanic.
