Turbo Reliability VS Supercharger reliability - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

KGB · 06-23-2014, 02:50 AM

H guys. So I want put a turbo or a supercharger in my 2014 BRZ. I just picked it up and want to get more power from it. Any advise as to which will be more reliable considering that warrenty will be void. And should I wait to mod it or is it safe to go ahead and throw a supercharger or turbo at 1000km?

any advice would be much appriciated

Personally, I'd wait untill the warranty was up. But I'd go turbo.

I'd personally wait as well. This will give you the time/money to do all the supporting mods first and also give more time to the turbo/supercharger companies to develop more reliable systems.

If you can't wait and want to do everything at once, it is really up to you and what your goals are with the car.

If it is just more power with reliability, I would go supercharger.

Check out the "Forced Induction" section of the home page on this forum. I would recommend doing a lot of research about each one before you make a decision.

draggin_az · 06-23-2014, 10:38 AM

i recommend doing whatever the fuck you want. its your car.

with that said both are reliable as long as you stay within each respected limits. finding a reliable tuner......thats a totally different story and should be #1 priority.

Disclaimer: I don't have too much auto experience and can be considered an auto noob and this is just my opinion.

Ok, disclaimer done...

To each their own but from the research I've done for my own needs I've chosen to get the Vortech kit. I'm not looking for a monster car since this is my DD. There are numerous folks in the member journals with supercharger kits that are perfectly happy with them and say they are low maintainance. You will easily find people with 250Hp and up to 300Hp with supporting mods. The Vortech kit is priced similarly to most of the turbo kits and offers similar gains.

The down side, from what I've found, with a supercharger kit, are once you have gotten all the power of from the supercharger that's it. With a turbo you have the option of installing a bigger turbo or something, but not with a SC.

That's my take on it and happy hunting!

Reliability comes from designing, building, installing, and tuning. Any four of those areas can go wrong with a turbo or SC, leading to all kinds of problems. Tuning seems the area where most people go wrong. Vancouver is a large city so it must have some decent Subaru tuners. I would talk to them. What do they feel most comfortable with? Big power is possible with either kit, but big power means big money and bigger chance for problems.

a supercharged car is always under parasitic strain even at low rpm and builds boost based on RPM. So everytime you drive at a high rpm the car makes boost. Even if just merging on to the highway under light load. Turbos only build boost based off of load (for the sake of this response and not getting complicated) so I can shift at 5,000 rpm with 5-10% throttle under minimal load if I want and not be making much if any boost. As far as my car is concerned it still thinks its stock until the load is increased and boost builds. Supercharged cars know no difference. HP per RPM or HP per load? Someone could drive a turbo car indefinetly and never get into boost. The car would never know its turbo'd and would last just as long as stock.

thanks for all the quick responses, you guys are awesome! Im not looking for stupid power but with that being said im am coming from a 2012 shelby and I know there is no comparison but I want at least around 260-300hp. My budget is around $6000 maybe a bit higher with the install. I really dont want to wait 5 years for the warrenty to expire because by that time im probably going to be buying an SUV anyways for the family. I want somethimg that does not require a lot of supporting mods. Just exhaust and intake but thats about it.

Thanks again for the input.

KGB · 06-23-2014, 06:57 PM

ps. the exhaust and intake is a separate budget.

Reaper · 06-23-2014, 07:04 PM

speedbydesign is about all you can afford on that if you include tune, clutch, fuel system, oil cooler, gauges etc. You might need to keep it around 280WHP at that budget. once you break 300whp you need injectors, fuel pump, clutch and possibly an oil cooler.
I just had a conversation with a guy who didn't realize ecutek with racerom, a tune and a clutch would end up costing him over 2,000$

KGB · 06-23-2014, 07:23 PM

do I need a clutch if under 300hp?

KGB · 06-23-2014, 07:31 PM

sorry didnt read properly. Under 300hp, can I get away with just a turbo or SC without any supporting mods?
