Newbie Ready to Start Mods
 

Guys, I'm a newbie to this forum and to my 2016 Scion FR-S, I just finished breaking her in (I have 975 miles) and am ready to start the mods. Any suggestions? I would like to start with the basic bolt on exhaust and headers.

What is everyone's opinions on equal length vs. non-equal length headers? Here's some pics of my new whip!!!!

I'd suggest you drive the car and then decide for yourself what you want to change based on how you drive.

Thanks Cole!!!! I have driven the car almost 1000 miles and really needs major mid range power, but given that, I'd like more power everywhere!!!! LOL!!!

read the sticky post here probably a good start

WOW!!!! That's a lot of great information steve99!!! Thanks!!!!!! I was looking at some of the dyno graphs and I guess that explains why I am looking for some mid range power, what's the deal with the dip in the mid range looking at the graphs on the link you sent?

manufacturers have all sorts of constraints when designing engines like fuel economy , NVH (noise vibration harshness) emissions regulations.

The dreaded torque dip is probably a combination of all of those.

Tune and catless headers will almost eliminate dip especially UEL headers, unless you want to go to the high end eL headers like ACE and custom dyno tuning.


If your on a budget

get UEL headers and a tune you can do this for about $1000

E85 fuel if available (with appropriate tune) will net you another 10-15hp over petrol, depending on quality of your petrol.

What is you opinion about UEL and EL headers?

EL header is traditional sound for a 4 cylinder
UEL header is classic subaru boxer rumble , dropped cylinder beat, similar to wrx.

EL header generally produce a couple more peak horsepower
UEL header generally produce more low/mid-range power/torque but can fall a couple of hp short in top end compared to EL header.

Tomei, gruppe-s , jdl , openflash etc are all good headers

Plenty of flash & go, or off the shelf tunes for these headers.

These headers arround the 500-700 mark and a tune with ecutek or OFT about $500 so arround $1000 with tune.


Nameless, p-tuning and ACE are the higher priced ones.

ACE probably the best but is expensive and you will need a custom tune to get best results from it, produces the best of both el/uel header power/torque. (its EL so you get EL sound.)

These headers about 1300-1500 and then you probably looking about $800 plus for custom tune

so over double the money but gain is maybe 5hp or so, if you want the best then go for it.

Return it and go buy a Mustang

What're you going to do with the car? Any plans to do track events or autocross?

Congrats btw!

Welcome

In general for these cars most UEL headers powerwise give more gains in middle, less on top. Vice versa for EL, hence UEL might be more fit for daily driving, EL - for track racing, as there one usually keeps in high powerband anyway.
Except maybe that current 'top' header Aceheader 4-2-1 type 350 is of EL design yet it gains a lot in middle too, essentially best of both worlds (at high price though) :).

If you want significantly more power in the midrange, I'd save up for an Edelbrock or JR supercharger, or ideally turbo if you know what you're doing. Basic NA mods (header, tune, etc.) are fine if you just want a little more in the midrange, but you need to wind it out to redline to reap the full 20-25 whp gain.

Think specifically what area you want to address and mod accordingly.

As to UEL vs. EL, I prefer the UEL sound. But I would be willing to sacrifice that sound for one specific EL header - Ace. Seems to be the best header on the market from a performance standpoint.

I think a supercharger is a bit out there wouldn't you say? He's just now wanting to get into bolt ons and spending 5k+ for these superchargers might be a little excessive. With that being said I believe everyone here on the forum would agree that Header, Intake (drop-in), and a tune nets the most bolt-on horsepower besides switching gas. Don't get me wrong those superchargers are possibly the best on the market right now and correct me if i'm wrong but can't the Jackson Racing be tuned with a OFT?
