Single, simple mod for a bit more boost
 

What is the best single, simple modification that you can do to a 86/BRZ without forced induction, that can give a boost in power?

My dad says it is the cold air intake system, other thoughts and votes? And experience with cold air intakes on the 17+ 86/BRZ?

A cold air intake is going to give you minimal gains. The intake on these cars is already so well engineered.


The best bang for buck mods have already been covered on this forum all over the place, try the search feature out.

For what you want it would be three options:
1. ECU tune aka Open Flash Tune or equivalent
2. Free flow exhaust aka Headers and muffler
3. E85 fuel.

All those can be done with under $1000 give or take if it's on sale/used what not.

As for personal preference, neither are not worth the price for the gains. If you want power that is worth it, save up or bite the bullet and get a turbo/super charger. But that's just my opinion.

As for the cold air intake, that's really for pre direct injection cars. Ours are pretty good from the factory.

Drop-in filter and Stage 2+ E85 tune w/ stock headers via the Open Flash Tablet. ~$550

Get a tune. Best thing for your cars health, absolutely. Also your best standalone gain. And it doesn't make your car sound/smell like trash.

I saw good gain from header and tune prior to going FI. E85 is a good gain as well if it available in your area. Cold air intake is a waste of money in my past experience.

I too would say a tune. There are several options with a canned tune. If you are thinking forward toward Fi then get one from one of the big boys that can supply a future tune using what you already have.

Tune, hands down. Get an Open Flash Tablet. Ideally along with an uncatted UEL header so you can run stage 2.

easy.

sell it and buy something with a larger motor.

Good feedback, I knew each platform has distinct differences and this comment was maybe just from the hip. The OEM intake system is simple and beautifully designed.

How much of a difference would a drop-in filter make? I'm not expecting crazy gains obviously, but just curious because I've heard aftermarket intake systems weren't worth it. Pretty cheap and I could spend a little bit more on some headers to go along with the tune.

While I don't think the stage 1 tune I run has given me any more hp it has helped smooth the torque curve out quite a bit. This has helped the driveability and made it feel better. It also helped with mpg a little bit as the engine wasn't in the dip zone in normal highway driving.

As others have said if you can only pick one get a tune. Open Flash tablet is good enough without physical mods.


Headers and a tune really wake this up if you can spring for 2 mods.

filters are all a balance. get a free-er flowing filter, it inherently can't filter out debris as well as a more restrictive filter. but it allows the motor to breathe easier. which would allow other changes to the motor to be more evident.

I found no restriction using a OEM paper element.

Drop-in K&N filter is the best bang-for-the-buck. Yo get slightly more from a full intake kit from K&N or Injen, but not much and some actually DECREASE engine power. Do research. But we're talking 5 HP at best.

A tune and a drop-in filter will get you some gains.

You're in CA so there is not much you can do with the exhaust. But going catless and tuning is a cheap way to get more power. Gut the cats + tune is about the cheapest way to get more power.

E85 is an excellent way to get more power, but if you ever need warranty work, you're pretty much screwed.

FI is expensive and bye-bye warranty.

To me, K&N filter had *zero* gains. I had it and I wasted the money. I am glad I did not waste even more money with cold air.

i just can't get into the 'rebuildable' filters like the k&n. i don't like the inconsistent nature of a human hands re-oiling the filter to prevent engine damage, and i don't fully believe that re-building them properly removes all the crap that the filter first caught before the process.

so i always use non-reusable filters. i also throw away toilet paper after using it, but hey, call me a weirdo.

build thread

LOL

It'd be nice if that had a real build thread and not some questionable numbers, questionable mods and a chip on the shoulder.

I agree with most of the guys that the air intake and exhaust header should make a small but noticeable difference. With no mechanical mods I just started a new diet of 93 octane non-ethanol and noticed a small but satisfying increase in all performance parameters. Of course, you have to have a reliable source for such stuff. If you live near a large lake frequented by power boaters, you should get lucky and find a filing station that sells good quality juice. Your engine controls will make enough of a change in the tune, and your boxer will love you for it.

:cheers:

Yeah you should have been using 93 from the beginning. Even in stock form they are designed for it.

I think his main point being it is non ethanol.

I think the effects of non ethanol vs E10 are mostly placebo, except for the quieter HP fuel pump if that sort of thing bothers you.

What is the difference between a OFT version 1 versus a OFT version 1.2 ? Another version ?

I don’t know much about cars tbh, but want to make my 2018 a little more fun to drive from what I understand I should first get headers then a tune ? To E85 if possible but stage 2 OFT if not

too many perplexing questions. No one wants to answer, to then be held liable ?!?!

Obviously, nobody here is going to give you the simple answer, I will. Put on 4 spare tires, cut your springs, remove everything from the interior, cut the muffler off. Car will be super fun, loud, and hellaflush. Almost for free
