Ryan for a private service/tune, or Boostwerks for a shop service/tune
($450 ~ $650 for 1st and 2nd option is the going rate)
best if you buy the parts yourself, ie 5L premium 10/40w oil, oil filter, fuel filter, coolant, power steer fluid, brake fluid, diff fluid (attessa as well for us 4wd'ers), bcpre6 .8mm copper sparkies,
grab a gates racing belt set for $300 (belt, tensioner, pulley, rings/seals)
oil and water pump for RB, around $450 there for new
might need the exhaust studs checked at same time.
probably advisable to check and replace gaskets, ie exhaust manifold, intake manifold, turbo gasket
but doing that adds up to a grand job.
although you then know she's good for a fair while longer now, probably for your ownership.
a safc and nismo adjustable fuel pressure regulator might be a bit of fun, to get around the 5000rpm spot, and gain some more power
but youd want a full exhaust system, good induction and intake, better fuel pump, and then the mods really start
so easy to fall under the spell LOL
