Engine Blown [Turbo]

[Irace86.2.0]

91? E85?

[Irace86.2.0]

What GenRuleAThumb said, 10psi at redline? or are you hitting peak boost earlier and the wastegate is keeping boost flat from there? Too much low end torque maybe

Next two most common causes of failure are spun rod bearings (from low oil and/or oil starvation), and valve train failures (from over revving the motor and/or manufacturing defects in the rocker arms).



Depending on your budget and goals, I'd say at a minimum you'd want to rebuild with forged rods and pistons. A damper pulley is also a good idea in my opinion.

I 2nd the damper pulley. If you're interested I have one for sale.

Full boost around 4600rpm. Flat from there
Peak torque 328Nm at 5200rpm

It seems like a decent amount of power for 91 and definitely a lot of torque at low rpms, so even with a great tune it was a matter of time.
