Having troubles deciding Turbo or SC - Page 2 - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

With that being said, going SC is the safe route when it comes to the motor. So to speak. Each one has their pros and cons.

I feel neither one is safer then the other. Both present their own issues. With that said I prefer turbo.

For AX I'd want the throttle control of an SC.

Either way, it seems like 300HP is safest limit on a stock motor / drivetrain if you are going to beat on it in AX or road course.

I went with JRSC because it has the longest standing reliability in road course use and reliability and consistency (power) are most important to me. If I were into AX, I'd probably go with the Edelbrock SC. 300-350HP should be fairly easy since out of the box they are approx 280HP (more on a cool day).

why? · 08-03-2016, 01:28 PM

Are you going to always want more hp? Or do you want a nice boost and be fine with it? Honestly that is what matters. The SC is great for what it gives, but it is limited in how much power it can add, while a turbo you can easily keep upgrading and get ridiculous hp numbers.

I have a turbo frs and my buddy has a sc frs driven both. Can honestly say you cant go wrong with either choice. My buddy does more track racing, hence if thats what you plan to do, sc i feel would be the better route. Linear power feel, would be as close to stock with more power and better feel at the track. If daily driving, i would say turbo, reason being you dont have to be in boost ever if you dont want to be. Car will drive and act just like stock until you get on it and get in boost range. So just depends what you want man.

FRS Justin · 08-03-2016, 02:12 PM

At your desired power levels I would go S/C.. Why put yourself though all the extra requirements to run a turbo...

I don't understand this since you can get bigger SC and/or small pulley combo so depending on the SC, it should be just as good at making lots of power as a turbo...

I think it really depends on the kit (turbo or SC). So then the choice comes down to how you like the power delivered. Big blast on turbo spool up or linear from an SC.

One could go with the JRSC c38 kit and throw a high boost pulley on it with e85 and yield great results. That's a good option I guess.

But requires upgrades fuel pump and injectors

But what gets me is, the price for SC and Turbo are really close. So why not go turbo and get more power?

Unless you're looking for something north of 600whp, the SC kits don't have any less potential.

so would any similarly powered turbo setup.

With what everyone is saying I may as well go with the c38 JRSC with the upgrade pulley. Especially since I like to autox

Basically anything requires fuel pump and injectors. Don't expect to make reliable power without upgrading those pieces as well.

CSG Mike has experience with about every F/I kit out there. I would call him and discuss your options, Mike can give you the pros and cons of what your looking to do. I would also consider a edelbrock s/c too.

is there an upper limit to JRSC kit's intercooler? On the HKS SC kit, the supplied intercooler is pretty small, so going higher than .6bar on the system with smaller pulley poses quite few obstacles with heat management. So far E85 is not a problem on HKS but on pure gasoline, not sure how well the results could be.

I believe superchargers on our platform creates a more balanced car over turbo-ed version, purely my opinion.
