how much boost can the stock turbos safely run on 1999 s80 t6? not the engine just stock turbos. also does anyone know what turbos they are and how big they actually are?

Re: how much boost? (zturnidge)

they are hybrid mitsubishi TD03s<p>and the amount of boost is relative to the RPM & load. you could theoretically get the boost into the mid-20s (psi) during your run through the REVs, but you wont be able to sustain that up to redline. you will want to do engine work before you consider pushing these turbos to the max, or even upgrading them. they are good for a decent amount of HP.

I have the 17 psi ECU upgrade, and I wouldn't push the turbos past 18-19 because the turbos can't handle that. Anything more would be pointless....stock turbos are 13g's, same as whats on a s70glt .
