Who the hell cares about boost before 3k? Are you stomping on the gas at 2k? really? No... most people go SC because 2 things. Much easier to install and its cheaper. SC don't turn your engine oil into a hot mess and that requires less supporting mods. Much less, but there's a market for everyone. Just find you budget and go for it. Just don't take corners.

Now what are the intrinsic disadvantages of turbo?

Oh pfft heat, packaging, LAG!!! Things blowing up, oil supply lines clogging up, oil leaks. My original choice was supercharger. Then I was convinced by a very reputable source to go turbo. Today I spoke with Touge Tuning and they steered me towards supercharging. But after all is said and done, it's about 10K at least. If I wasn't planning to get married in the next year or two, I'd jump right in. But can't propose to my gf with a turbo lol.

OK so last question. What are your goals/wants/needs out of going FI at all?

I'm thinking that's what I'll do. I can't afford to drop 10-15K right now anyway (that's what the mechanic quoted me for a supercharger kit + supporting upgrades). However, I already ordered a catback exhaust and if I get a catless front pipe and catted header (or vice versa) + OFT, I can enjoy more power and utilize those existing upgrades in the future when going FI.

If this is your major concern then Aftermarket Forced Induction is NOT for you. This route more than any is the most "pay to play". And I'm not just talking about upfront cost. Remember you are adding a completely new component that doesn't come in any way shape or form on the car at all.

Everyone here is correct in some shape or form. Some people slap on a turbo get a tune and they never look back. Other get endless issues. Even with the most reliable kits. But you have to take everyone's story with a grain of salt. The no problems guy could just be ok with the "issues" his kit has and so for him it's not a "problem". The guy who nonstop complains about his kit could literally be just complaining about the noise it makes. But for him that's a deal breaker.

I will share my experience as I find it's a bit unique and hopefully will shed some light for you.

I installed an Edelbrock Supercharger on my car at 9k miles. Brand new 2016 BRZ. Currently at 16k miles. Kit went on fine. No issues. No issues with tuning either. For the most part I got the drive into the sunset part.

I'm taking the kit off.

Why?

I don't like the throttle response. I don't like the vibrations it makes. I don't like how the engine feels heavier. I don't like how the engine feels below 3k RPM.

Not a single issue I have with the kit is mechanical failure or something wrong with the kit. It's all objective and picky things.

Moral of the story. Think real hard about how the car will be after the kit is on. It WILL change. Not a single kit out there will retain that. OEM feel. Anyone who tells you otherwise just doesn't really get bothered by it. But it does change. And not always for the better

Hope this helps

I went supercharger for the throttle response. I came from an r53 Mini Cooper then to a GTI and now the BRZ. After leaving my Mini Cooper I missed how quickly power came on relative to when I pressed the accelerator. Sure the GTI makes peak boost stupidly low but even when you cruise at 3k, hit the gas...there is lag...then you go. It's just how turbos work. With the JRSC I hit the gas and it's power now. Not in a half second when I need to already start braking for the next corner, but right now. Reasons why I went JRSC over Edelbrock was ease of install, very good thermals, and track proven. Not that Edelbrock isn't any of those, it's just that the JRSC fit me better and how I like to think the BRZ should be driven. A high revving car.

Can you go into more detail with your thoughts on this? Particularly, how the EBSC affected throttle response and engine feel below 3k rpm? I have been under the impression the twin screw SC systems have the best low rpm throttle response.

I'm curious to hear about this as well.

My sprintex-modified car has better throttle response than the car on the stock tune (in my opinion, but its pretty obvious to me). Any aftermarket tune I've had improved the throttle response over the stock car.

The sheer and complete lack of the 'stock torque dip' with the sprintex makes the car deliver a completely different driving sensation. The torque dip was 'mostly' gone with just a tune and header... but running on E85/SC there is zero, and i mean zero, inconsistency in the pull from 3k to 5k. i don't do heavy throttle below 3K, but coming off the clutch in low RPMs is a much smoother experience than stock (which had no torque at all under 2k or so).

My biggest disappointment with going turbo is that I can't​ go WOT for very long before my speed is in the illegal zone ��
