Turbocharged vs supercharged
Ok I know someone probably has this title. But I’m wanting to know what is better for my automatic 13 frs a turbo or a supercharger I’ve looked around and can’t find a comparison for an automatic everything is on a manual. Any help would be appreciated thank you

read these three pages over and over. you will understand why supercharging is more cost effective than turboing

Goal?
Budget? Car use? Mechanical skill level? |

My 14 FR-S is automatic and I have JRSC installed for over 3 years and 35K miles.
There are reviews below. Whatever your goal is, track or daily drive, this the best option I could see for reliability and power. Stay with the stock engine, buy JR tune, don't add any more power than the kit offers, just add an oil cooler (JRSC has options for that). You are all set. |

Low psi turbo for a daily.
JRSC only for low budget track build. Turbo for high budget track build. Auto has long gears pairing well with turbos Turbo much more efficient less parasitic loss. More power for less Boost and More whp per crank hp so less stress at same power level. Can setup boost controllers/wastegates to do boost by gear boost by rpm etc... for even greater control and safety. Catch can, Oil cooler and trans cooler recommended, SSP valve body good upgrade too. |

100% turbo. Less complicated, easier maintenance, much more pliable for a goal of low or high power.
Get -all- of your supporting mods before buying a kit. It's easy to be complacent once the car runs and drives and you're thinking "hey... actually it runs good, I don't need 'catch cans' and an 'oil coolers' what knobs" |

JRSC is the most efficient solution. I hear this parasitic loss bs all the time. But I get 30 mpg with normal driving which is as good as the stock engine. JRSC is also the simplest solution for FI, there is not any room for argument there. Turbo is the most complicated FI solution. It requires proper thermal management which is so much harder than JRSC. And, unlike JRSC, header is replaced with turbo.
The only advantage you can get with turbo is the higher torque at low rpm which can lead to reliability problems in the long term for your engine. |

JRSC isn’t bad by any means. definitely been overly hyped and marketed by certain vendors on here though.
People trying to flip one of it’s biggest flaws “no torque” as a strength. You can always turn down low/mid range but JRSC can’t turn it up. And low/mid range torque is what gives you that fun hit and added power for daily driving. JRSC is basically stock below 5k then it comes to life. Parasitic loss is about needing to make 300 crank hp to make 240whp. VS a turbo making 300 crank at 260whp or only needing 280 crank (less stress) to make the same 240whp. That is parasitic loss. Not MPG which would be impacted but who cares about a few MPG difference. Turbo for a daily doesn’t require much heat management. For the track then 100% which is why turbo track builds are for ballers. JRSC is the best low budget FI track build. For a pure daily a turbo is better, even more so with autos because of the gearing. Superchargers in general are simpler than turbos. But if he either A. has tons of mechanical skill or B. is paying someone it doesn’t matter. For a entry level wrencher Supercharger is easier. Main reason i chose supercharger. But having the knowledge and skill i have now i would have turboed. So again. Before anything can be decided OP needs to answer the below as JRSC is far from a best in any/all scenarios. Goal? Budget? Car use? Mechanical skill level? |
