ZD30 Boost

Thanks MUDSKI

Working on the rig tomorrow, swapping intake manifold, egr block and provent.

So will check the ic when its off.

You will rarely see it spiking to 20 psi under OEM control with standard exhaust and rest of the Mr Nissan control. With OEM controls max boost is usually 14-15 psi as ECU starts backing off VNT vanes as soon as you floor it.
Put bigger exhaust and take out EGR and it will go over cause now the variables have changed. As for the LIMP mode it usually happens if the MAF voltages exceed certain levels at certain RPM and if boost exceed 18 psi.
Cheers

Thanks for the advice Boys ( a bit slow on the reply i know )

Swapped the intake manifold and throttle body for one that i had cleaned, completed the egr block and fitted a provent.

Its a new rig, bewtter take off and lower egt, at 100 now running 14 psi and 220nto 250 egt.

Cheers

Maybe a touch high on the boost, rule of thumb is 10psi at 2000 rpm.

Will do threedogs.

You have a needle valve fitted too? If not I would strongly advise to do so. You will then have complete control of the turbo then.

How much MUDSKI ?

Mine haven't arrived from Italy yet. I was told they will leave the ital's shore on the 14th of this month and then its another two weeks from then. Price wise I haven't confirmed this yet but I will think it will be around $75. Why get them from Italy? I have gone through 9 different needle valves to date and found the first one I tried the best, albeit one of the most expensive it worked the best.
If you need it sooner you can get it from Dependable distibutors for $85 plus GST, plus freight which equates to around $105 I think it was.

Cheers.
Mark.
