So I recently modded my 08.5 speed3 and was wondering if I'm boosting too high for the stock internals? I'm logging spikes of around 21 psi on the following mods:

Turboxs dp & rp, Cobb SRI, Cobb AP, Synapse BOV

I live in Denver at about 5600 ft elevation if that would have any effect, it's also cold right now.

Thanks for the help.

well other than technically your in the wrong section...there is a mazdaspeed section this for forced induction on non factory turbo 3's.

i have worked on a few and id say your deffinatly running a little too much boost for stock rods, my buddy threw one at 20psi, some throw them at lower numbers. although my other friend i put a gt3076r and he is running 15psi on it with no probs stock bottom end. so if you could turn it down to like 18 i think you would be a lot safer
