(04-10-2020, 09:59 PM)wiseman89 Just to comment on the last post, I do believe there is a post on here from ERX where he says his motor threw a rod. I hope he rebuilts it and gets back into the forums here, hes provided alot of great info. Looks like hes also been beating on that motor for a while to with big turbos.
Yes his Chinese wastegate failed and he overboosted the motor to over 4 bars or something predictably fatal to the stock rods.

Anyone doing a high power build should just swap the pistons out to lower compression at the same time. Lower peak cyl pressures are also kinder to rods.

My experience is these engines need their 20+ compression or they will run like garbage, knocking and smoking.

What number did you take it down to Baldur?
