Low Boost

[portaz]

Hi guys sorry if this question has been asked before but I have spent some time searching and couldnt see it, I have an r32 gtr stock except for pods, exhaust and cam gears (set to 0) and I just installed a boost gauge and it reads a max pressure of 8psi. The restrictor is removed near the solonoid but i am not sure about the other restrictor on the turbo lines. It has a small exhaust leak from the rear turbo but I wouldnt imagine that would cause it. Any ideas? From what i have read that without the restictor it should be at 14.7 (1 bar). Should I just add a boost controller or replace the lines between the turbos that have a restriction in them? Any help is appreciated .

fix the exhaust leak

you are loosing precious back pressure

So would that be the cause of only acheiving 8psi?

yes

exhaust pressure = drive the exhaust wheel harder = drive the compressor wheel = increase boost pressure

if you are leaking exhaust pressure you are loosing precious "kinetic" energy

thus you get sluggish exhaust wheel performance, which in turn results in sluggish compressor performance

its probably a bit laggy as well

Bugger I was hoping to get a run in at wsid in standard form but if the turbos have to come off I may as well put my new ones in no sense in doing the job twice! Thanks for your help

yeah if you pull the turbo's off at very least do all the gaskets

but yes if you can afford it, replace the turbochargers at the same time and gaskets

get all the gaskets from nissan OEM either via rhdjapan.com or nengun.com or greeline.jp

Thanks mate will do haven't used nengun before but first time for everything and then there the nisstune, injectors and a tune oh well it's only money I guess!
