Well thanks guys. I am new at this, my son is not. Thanks Churchx I picked up a k&n. I'm not sure how much I want to do in hopes the 2017 FRS is like the pics I've seen?

Does anyone know what size bolts to use between the OFT UEL and the stock overpipe?

it in the borloa header install guide attached to first post

M10 by 35 mm long, get lock washers as well

added pics of de-catted stock header and stock snorkel mods to first post

Just an interesting "cold air intake" comparison.... ;-)
This is for NA engines.

This is an awesome thread. Almost makes me glad I had to wait a couple of years to get my BRZ. So much research has been done now that it will make it easier for guys like me to chose the right path for modifications.

True! Had my 86 for 2 years now, but still stock... Now I'm slowly starting to decide on the mods I want. Just soooo much info around!

This is sexy info. Thanks!

Exactly. After what has been learned so far and shared here, I now know that my BRZ will be a tune only car with a drop in filter for performance mods :)

If I install a TRD intake would I need a tune? If so would Ecutek be the way to go or does Haltech do ECU tunes as well?

TRD Intake maf scaling will be very close to the stock Air box scaling so no tuning required.

For the sort of monet a TRD intake cost gains will be minimal, you wont get much more than if you bought a $50 drop in dry filter for stock air box like Apexi filter. The other good thing about oft is you can onsell the whole system if you flash your car back to stock and loose less than probably $100 if you move on or sell car.

With Ecutek the tune/licence is not onsellable

Haltech is a complete replacement ECU and will cost thousands plus tuning.

Ecutek , Open Flash Tablet Tactrix/ecuflash/Brzedit ect alter the settings and parameters in the ecisting stock ECU so with tuning your up for $250 to $1000 depending on which system you choose and your skill levels at tuning.

If your just talking a naturally aspirated car with bolt on mods either find and Ecutek tuner locally then you can get a tune for about $500-600 with ecutek licience as you will not need to buy cable to flash (additional $350)

Or buy an openflash Tablet OFT and you get device and tunes for basic mods and e85 fuel included, very good if you have no local tuner all up cost $500 http://openflashtablet.com/Automotiv...OFT/index.html

Thanks a lot, very informative.

Tuning needed for header installment?

I was going to purchase a header for my brz before I did anything to the muffler but now that I see it has to be "tuned" I might just settle for something easy, like a Berk Muffler delete.

I believe it's a yes. Needs oft, ecutek or a custom.

So dissapointed. Some other 86er mentioned that in a car meet when I said I was going to get the Borla header. Lost motivation after that, and this just re-assured it

Well the car will run, but you probably wouldn't notice much difference from what I've read

So, in short. Tuning is not required? but recommended?

Definitely recommended.

Uber stickiness

Thank you
 

Thank you for this sticky. One of the best compilation stickys I have ever read.

Very much appreciated

This is starting to get me frustrated. What do you mean "the tune will disable the cel code"? I literally have no experience with tuning but I want to install catless uel headers on my brz, so I will most likely get an OpenFlash tablet and install them both at the same time. I've tried for days to find a video or picture of someone tuning this car for P0420 and I can't find anything. Some people are saying "just delete the code" or "the tune will fix it", but obviously just plugging in the tablet will not fix the code.

Can anyone please explain or provide a link that will help me understand tuning for this code more? I've read both the tuning and exhaust stickies and they are still using those non-specific descriptions. As for tuning for header performance I'll probably just have someone at a shop show me how to do it, if of course they know how.

TL;DR - what do I have to specifically do to access the ECU and delete P0420 or any other CEL code? I will most likely use an OpenFlash tablet.

The stock ecu calibration or "tune" is set up for stock components including a catyltic converter in header.

If you remove this cat with catless header you will cause the ecu to set CAL light due P0420 cat efficiency.

a tune designed for catless header will optimise many settings for a catless header to make more power and it will also disable the cel code for cat efficiency so it does not light cel, more info is in first post in this thread.

If you buy an OFT it comes with tunes for catless EL and UEL headers and the cel code P0420 will already be disabled by the tuner no need for you to do it, just flash the correct tune and your done

Thank you, this is what I was confused about. Everyone was making it seem like the tune did all the work and I didn't have to do anything, but that seemed fishy to me. Do you have any recommendations on where I could go to learn about specific tuning terms and what they mean? I'd hate to blow $500 on a tuner and not use it to it's potential.

I appreciate the response.

Their is a bunch of pretty coloured words in the post above and below if you click on those especially the "OFT TIPS " one should be a good start :-)

Awesome. Thanks a ton man :thumbup:

If all I have is a Greddy SP Elite Axle Back Exhaust, and I'm just looking for something to increase the sound of my BRZ a little bit more would it make sense to put in a front pipe? I'm looking at a front pipe because I want to avoid CEL lights and messing with the cats, like most headers do.

Front pipe has a cat as well, but the O2 sensors are positioned around the primary cat in the headers, so idk if swapping it will flip a CEL. I've seen a lot of people on here go with a front pipe mod though with no reported issues so I think you'll be good.

Thanks, would that give me a better sound as well?

Deleting a cat will most definitely improve the sound.

Steve99, what package gets you header, e85 and tune for under a grand? also if I do e85 and tune first then add header later do I need to re tune?

you could do the oft/ofh combo deal $1055
http://www.openflashtablet.com/shop/oftofh2-combo/


or say gruppe-s header at about $470 plus an ecutek flash and go tune for about $600 think moto-east or deliceous do flash and go tunes for arround that.


if you want to start with tune on stock car then add header later then the oft might be cheaper as you get a set of tunes you can flash yourself for stock cars or cars with header on 91/93 and e85 fuels.

alternativly moto east do 4 fuel map switchable tunes for 91/93/E40/E85 but you would need to fit header first, also depends if you have local ecutek tuner to flash tune or you will need to buy or rent an ecutek cable to flash tune this will add to cost

Hello Guys,

I might be on the market for a 2017 BRZ/86.
Sadly they are both only on order and can't test drive one.
Lot of review talk about power issue ( not enough ).

I currently drive an Clio 3 RS 197HP/1250kg and I am pretty happy with it.
adding "easy 30whp" with bolt on and tune, HOW the car feels?
30whp seems a lot for bolt on a n/a car and should make the car more responsive?

Not looking to have a 0-60 car, but must be king on the twisty road :)

Thanks

Not sure exactly what you are asking. Test drive a 2016 in the lot my friend itll be the same car IMO.

Adding 30whp to the car, that is make it make a huge difference?
I heard because of emissions regulations there are lot of restrictions.
People who did full bolt on tune, still unhappy after?

There is no BRZ/86 at dealer, so can't even test drive one.

I am going to see how much power I can make NA before going FI. There are many people on here that stay stock/ do full bolt on/ and go FI and each will tell you what they are happy with. I dont think there is a way to tell you what will make the car fit you because everyone is different with their own opinions. Just depends on what you are looking for. Like everyone on here told me before I bought the car. "Drive the car first and see what fits you"

I guess I will have to put one on order and see by myself :burnrubber:

Thanks

For sale
 

I have a Greddy intake and axel back exhaust for sale if anyone is interested.

Here's the order of my mods and what I felt after install:


1: K&N Drop in filter:
Throttle response and top end HP was noticeable. I was surprised! Sounded throaty too!


2: OFH/OFT UEL Stage 2 93 OCT
Same opinion as most people. Ride quality greatly improved, especially during idle and low to mid range RPMs. TQ dip was only noticeable when I had a fat body in the passenger seat. I actually thought the car was a bit slower in the top end, but no real significant power gains with my butt dyno.


3: Invidia N1 CatBack:
Got loud and drony, but I got used to it. No real power gains.


4: OFT Stage 2 E85:
Yup. I got lucky and found a gas station that is right between home and work! Once I let the ECU learn for an hour, I went WOT and felt a SIGNIFICANT increase in both HP and TQ! I am still on my first fill up and I've been bookin' it everywhere I go! No more dropping 2 gears to pass (I spun out, which told me I need stickier tires). I can't wait to fill up again, let the ECU learn...again, and change the oil to an E85 friendlier oil. 5W30ish?


Needless to say, I'm going to stick with N/A for now. I'm not too sure how long it's going to take for me wanting to go faster with FI, but I'm very happy! Still looking to maybe go CAI, or just an intake tube. Any suggestions on intakes????

Oil weight has nothing to do with being E85 friendly. You can get 0/5w20 oils for E85. You do need to change it twice as often though.
