^See like that, most people aren't going to leave well enough alone if the turbos go with that opportunity to do a few other things, so I'd worry about the claim that they'd been replaced without anything else being done, equatorial.
With that Haltech, and rebuilt turbos, I'd suggest a few other things to go along if you can spare it since you won't be able to fully utilize them to their full potential.
-MAFs. The OE units come apart internally, and can be repaired, but they max out in the 400-450hp range and can give you some fits when they start to die like many things on this car. Z32TT MAFs with retrofitted pigtails have worked for a long time. The R35 MAFs in adapter pipes are getting more popular as well (what I have on my car) and they're upgradeable. Or just go MAP if you so desire and the Haltech has an associated sensor.
-Injectors. The 444cc units are prone to leaking, tired, and won't do for much above 400hp with max duty cycle even when new. Along with, the fuel pump can be prone to failure and should prob get swapped here at the 25 year point if you're aiming to push it harder.
-Clutch. You start getting above 400whp and the OE unit will start giving up the ghost if still installed.
How's the condition of the ignition peripherals? coilpacks, plugs, igniter, and harness? These can give you some serious fits too, and higher boost can blow out the spark of tired coils or mis-gapped plugs at higher RPM.
Just food for thought. Even if you're not after big power like you suggest, these will help it run much more reliably.
