So I'm on my way home....
And I smell Gas! Pulsation dampener's going out.
If Memory serves me right, the PD is on the Secondary fuel rail correct?
anyone know if I can just swap the N/A secondary fuel rail and pd to a Turbo II secondary/pd?

And the Banjo bolt mod may lead to lean or overly rich conditions at particular RPMs.
So that is not a sound recommendation.

Lol, I typed secondary didn't I, sorry man my mistake, wasn't paying attention to what I was doing.
I looked at it closer today, and its not leaking, yet. but the gas smell can be pretty strong at times. I guess I'll pick one up from Mazda. Wouldn't want a engine fire to ruin my turbo project lol.

The bottom line is...there's no hard proof that eliminating the P.D. on this car, and installing a Banjo Bolt (Using new crush washers) in it's place will have any ill effects.
I'm going to recommend the O.P. go ahead with the Banjo Bolt.
To the O.P.: Use NEW crush washers when you do this. The Bolt can be ordered, or taken from an S4 Primary Fuel Rail. If I recall correctly, the size of the bolt is 1.25mm x 14mm. Ice can correct that if I'm wrong.

1st You said use the S5 rail- which is more expensive, proven to fail the same way as S4 rails, and can not use a banjo bolt. So that was bad advice.
2nd: Why take the risk of blowning the motor instead of buying a new $150 part??? if you don't like the Mazda one- fine, buy any of the 3 or 4 aftermarket ones (several are sealed units) and for $150 have it done correctly. But just eliminating the part is stuiped, and no different than the morons that remove the low coolant/Low Oil/ Engine Over-rev buzzer because they can't figure out how to bleed the coolant or have a bad $20 sensor.
I personally know of two Turbos, that used to have problems at 4500-5000 RPM (you could see the drop on the dyno charts) that all they did was replace a Banjo Bolt with a real PD and it solved the drop in power at 4500. So yes I suppose that it was "conclusions are most likely based off of poorly aimed accusations" for the real reason of a power drop.
But I look at that was bad advice to suggest using a banjo bolt.
Fix the car- don't **** it up further by half assing a repair. Hell, for the price of a decent tire, you could fix the car correctly.

You could use an S5 fuel rail. It is a fix, but no telling how long it'd last.
Second, we're not turning this into another Banjo Bolt versus Pulsation Damper thread.
Third, isn't the O.P.'s car currently an N/A? Banjo Bolts work fine for stock N/A's.
So don't say that it's bad advice. I know you don't believe in the mod, but A LOT of people do. It's up to the O.P. whether or not to do it.
Edit: I forgot to mention, that I *DON'T* recommend the Banjo Bolt for anything other than a stock or relatively stock N/A.
I also forgot to add my concern with a new P.D. is: Where's the guarantee? It could start leaking after some time...maybe not a very long time. Or, it could last as long as the original one did. It's rubber.
Now, Icemark. You're one of the very intelligent people on this forum. I respect that knowledge. But just because you personally don't trust a modification that is commonly performed, doesn't mean it's 'bad advice' to give. That's all I will say further on this subject, I am done with this thread.
