Hey guys just wondering if anyone no's some info on the 2011 Toyota hiace 3.0 ltr turbo diesel, I'm just wanting to no what they run as standard boost an what they can handle safely standard? Cheers

I saw a video of one and it looks like they run around 15psi stock (that seems like a fair bit) From what my mate tells me (he has an old turbo diesel Cruiser) diesels can handle a fair bit of boost usually better than a petrol car can. do some research, google it.

Yeh I new diesels ran more boost that petrol cars, Im guessing they run around the 10-12 mark. I'll google it an see what it brings up ---------- Post added 02-11-11 at 19:38 ---------- 16psi wow didn't think it would be that high! I wonder what you could safely turn it upto??

my bet is you cant turn it up without a tune considering they are more then likely a VNT turbo which is computer controlled.

Woulnt happen to be the same engine as the hiluxs? Because I know the older hiaces ran the 2.8 3L engine from the hiluxs.

my understanding of diesels is that your not necessarily going to get more power from turning the boost up, but more so from fitting bigger fuel pumps. But the new hiace is awesome, you wont regret it. it is the same motor as the hilux so parts are easy to get if you need them

If the pump has a boost compensation valve it will add more fuel as you add more boost also if its common rail you will just need a remap. If it just has a base fuel adjustment this will add a percentage (depends of how much you turn it up) of fuel over the entire rev range. By adding more boost you will not add more power as there is not the fuel there to support combustion and EGT's will go up. By adding boost and more fuel to compensate power will go up until there is to much fuel noticeable from black smoke. Power will keep on going up by adding more fuel at the cost off killing the 60year old woman driving behind you from inhaling the toxic plume of smoke. EGT's will also raise quite steeply 600deg is about the safe mark under load. Also the turbo will also most likely start falling off the efficiency range causing high manifold back pressures pressures what in turn will give you a steep rise in EGT's melting pistons, a turbo upgrade at this point is a must. In saying this diesels are much easier to gain extra hp over petrol engines. I have seen factory non turbo diesels see 30psi on a standard engine and net over 160rwkw and over 800nm. Maching turbochargers, airflow and fuel flow is a must to keep a diesel alive.
