Boo!, I can't even listen to them here! What are the results? I can't see pictures either, but if you can briefly explain, you'd be helping me out.

Props to navyboy doing it but we need someone else to do this with dyno access.

bump for results !

Engines don't blow from being rich. 14 is lean which will def blow a motor up. I have a Tt setup and I'd only do this mod if it sounded good. I could just turn the boost knob up for power so these cams if they do work well will mainly be for NA setups. Or built motors that want to retain the vvel and be more efficient with airflow.

Unless you owned the TT370Z, it's difficult to completely understand the relationship the owner had with GTM, whether the owner was an idiot and went against advice, or it was retuned, and done incorrectly. Only a complete moron would push 14:1 AFR on any vehicle, let alone on a turbo car.

Please just stay on topic as a lot of us can care less about how you feel about GTM and more about your results

As previously stated, you WANT to run rich. As rich as possible within reasonable limits. Running stoichiometric in general is never wanted, that's just the chemistry talking, and doesn't actually apply all that well in a motor vehicle. I'm sure a race engine (where blowing up is typically expected) could run stoich, but only with some pretty good engine reinforcement.

That said, nothing is more reliable than an NA car at similar build levels. NA-T cars are never a better choice than staying NA. Less parts to break, no possibility of boost leak or surge, less chance of blown gaskets, etc. etc.

your motor from the factory is the most reliable. opening up and installing these cams will bring the level of reliability down. if reliability is what you seek run things within limits and make sure the person doing the work is competent and make sure you yourself has a level of competency that you know what limits are. A turbo motor at a small amount of boost on a oem motor is more reliable then tearing the heads down and replacing the exaust cams or cams in general.

modifying cams is not a new thing, even in Nissan motors they have been doing this mod for a long time. Why would opening up the heads (which I don't think you need to in this case) cause any problems?? Look at the VQ35 motors, ppl have opened them up more than once changing cams, springs, valves, etc. When someone builds the motor they have to disassemble lot of components including the VVEL assembly and have been reassembled back using the same VVEL. Of course its not a Cold air intake you're installing but shouldn't be a problem if done right.
Of course its a PITA changing the cams but it is doable and more reliable than running FI.
From what I read NavyBoy is taking it to a Nissan dealership, am sure they would've someone skillful enough to open it otherwise they would've turned it down. Good luck, looking forward to the results.
