for a low budget (relative) FI track car i would do a centrifugal like JRSC. for a low budget (relative) FI DD i would choose Turbo. for a high budget (relative) FI track car or DD i would choose Turbo. I chose PD SC myself because for a DD it is better than a centrifugal SC, in my opinion. But I do all the work on my car myself, and didn't trust myself to do a proper turbo setup at the time i installed the SC so PD SC it was. So you could say for a FI DD that is your DIY weekend project i would choose a PD SC unless you really know what you are doing when setting up a turbo. |

The T518Z is a small turbo. Going with a larger turbo will not change the HP that much at a specific psi. It will change when the boost starts and how much max boost you can get. I believe that turbo is only good for upper 300hp range. In order to make more HP at the same PSI you have to control IAT and have a good tune. I am sure CSGMike can have a more detailed explanation. Plus his explanation of a “Properly” sized turbo for your goals.
And there is only one correct answer when someone asks if they should turbocharge or supercharge their BRZ...... “Yes!” |

and also make engine less knock prone so shitty-fuel friendly only downside of bigger turbo is slower spool, but brings only advantages.. also IAT (actually proper name is Intake Charge Temperature for a FI car) is lower with bigger turbo, for the same HP compared to smaller "properly sized" would be a kind of compromise between fast enough spool, and max hp Those 2 are one the contrary of the other in the choice of turbo size |

All of my arguments are facts, or as conceived as facts. The value I add is countering loudness of fanaticism. That is what I call trolling.

You either restated thing’s already said (which is fine to add reassurance) or just said false opinions/lies/mad up fiction. (Which is trolling, and adds no value). But I don’t see any NEW unique fact that you added to contribute value. But to each their own. Can’t control the internet. 🍻

Actually that's on ACN91. Just a good tune. This is with a stock front pipe in place too.
Turbos don't have the parasitic loss of a supercharger, so the power difference is what the supercharger is eating, all else equal. |

Because I'm not pushing big boost, a "more efficient" larger turbo is not actually more efficient for me. This can be determined with compressor maps and/or looking at intake charge temps vs pressure. The T518Z with ethanol, will easily clear 450hp crank/350whp. In fact, I do so on only about 10.5 psi. More boost than this goes into diminishing returns, and really should be done with a larger turbo, but I'm okay with the power I have! |
