can you get more boost if you run 510cc evo injectors and walbro fuel pump with chipped ecu to suit mods ?
anyone know how to achieve 14psi or run that using a tdosh vr4 turbo ?

You should be able to run 15psi easy as. Grab yourself a decent manual boost controller and a boost gauge

Take your time to set it up properly- little increases at a time to get it where you want it.

I'm getting in a bit late, but ages ago I did a 450cc injector J spec VR4 into a Cordia. 100% stock (well it had a dump and a 2.5 exhaust) and ran it at 15psi all the time with no dramas.
ECM Link, 399 MAF, 560cc injectors, 270 cams, TD05-20G @22psi, 3" dump, full 3" mandrel exhaust, intercooler, Fidanza alloy flywheel, 4 bolt LSD, EVO IV brakes, Strut braces, coil overs and sway bars.

I've also had a VR4 engine with 14b + 510cc + walbro255 @ 15psi
~80% peak duty cycle on 38psi base pressure (it's probably a lot cooler where you are though).
Went well!

A bit pointless having that setup with a standard exhaust and turbo...

Mate, I know it sounds all are kind of having a go. But install the 2.5.inch or 3 inch if you can and you will see a couple of psi increase.
See how you go, then look at a boost controller, whichever that may be.
I'll back Clutz and assure you that small gains as you go mate. I cant recall the boost cut on a VR-4 engine but from memory, about 10 years ago, mine had a cut around 16psi.
With a 3inch it had about 11psi and I used to wind it to 15, it made 220hp at the wheels and it was a giggle.
And just to show my age it was with a td03/04 hybrid. Basically, have fun, but do your supporting mods first my friend, exhaust etc....
Cheers.
