Well folks, I am running an r33 gtst with full exhaust system, front mount, induction filter.

My question is, on full boost my standard boost gauge goes to just below the 7 at the top of the gauge? Just about 2mm off the 7?

Is this ok and safe?

Not one for planting the loud pedal much but wanna know its safe to do so!

Cheers

If you are still running standard boost then it is fine. 7 psi is standard for an r33 for but with an exhaust and front mount it's likely to creep up to 8 or 9 which is still very safe. Get yourself an aftermarket boost gauge if you really want to know what it's running at.

The above is incorrect.

the gauge is in mmHg. 7 is around the 14psi mark, this is not safe for the turbo, and will no doubt be hurting power by sending the ECU into 'R&R' mode.

Please use the search for further info, this is quite a common topic. Also ensure you read the FI Guide sticky thread, it contains great links for those starting out.

Thanks.

      r34's love to squeal

      just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.

      My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.

      To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?

      So, now all you need to do is connect the 2 or 3x 12v feeds into the unit to permanent 12v, ACC 12V and IGN 12V that you can find in the spot behind the stereo, and the earth, and then it will switch on with the car.
