Turbo installed. Lasted 4 days. Threw a rod.

Horton what Turbo are you running? It seems like your exhaust is ok. Do you have a way to measure Turbine Inlet Pressure (ie TIP)? This will confirm or eliminate the turbo as a source of the problem. I suspect your TIP is going to be sky high. It should be less than 13-18 psi at that boost pressure. I bet yours is 25+

I'll write a technical reply when I find 5 minutes - for those who haven't read my intial reply above please do.
The exhaust is without doubt part of the restriction at the top end.
Connor please stop saying what boost it makes peak - some of these people genuinely think it's making 13PSi @ peak power still.
Might be worth you plumbing your boost gauge up to a pre-intercooler port connor, try and see what kind of pressure drop you've got through the IC.

Boost for dyno & ECU are inlet manifold sourced.
Which is why I suggested to Connor to source his boost gauge from the pre-intercooler source and see what it reads - if his intercooler is **** then the turbo could still be making over 1bar and be running out of efficiency. I didn't pursue this on the dyno because his IAT's didn't look bad at all.

He's asking where the boost control reference point is.

Either the turbo inlet is a garden hose (WRC anybody?).
Or the cam timing is off.
With everything that has happened in this thread, just saying "the cam timing is not off" does not satisfy me.

Pretty sure Dann posted a dyno plot just like that...motor blew up in a similar fashion ![](https://www.miataturbo.net/images/smilies/smile.gif)
cars with restrictions don't make that much torque in the first place.
im assuming the boost plot looks exactly like the torque plot.

Even if the car should make more power or the torque curve is weird or whatever I'm not fussed. The car drives great and I just want it to last more than 4 days.
As long as it's safe I'm happy
