Default best way to get more power from brz

What is the best way with basic bolt ons to get more power out of a brz? Any significant gains possible without supercharging/turbo charging? Im assuming intake and catback sint going to do much

Not really. Intake, headers/exhaust and a tune picks up a bit.

You could try calibrating the dyno to read ridiculously high. Good way to get the numbers up..

Try the BRZ subforum. More helpful than here since it is populated by BRZ owners...

Trade it in for a WRX or STI. but seriously, I haven't seen huge gains from any mods other than going for forced induction.

Headers, exhaust, drop in and a tune will get you decent gains while keeping the budget under FI (~190whp). If you want more you might as well go FI because NA power will be $$$. There is a fellow doing an NA build, you could always look him up, Chris Elek (Eleck?) IIRC. He's doing a built motor, cams etc. all motor. I doubt he'll make more than 250 wheel however and he'll probably spend atleast 3x times what a rotrex kit would cost.

Without going either a supercharger or turbo, NOS is it. You are not going to get that much on the already super efficient BRZ/FRZ motor with a intake, exhaust, and a retune.

header back, intake filter (stock intake is good to 300hp), e85 tune will put you to 200-205.(OFT Tuner) Huge difference and makes the car wayy more fun

I am not sure where people are getting all this from and what do you define as significant power gains? I would say from doing headers back with E85 and going from 176whp to over 200whp is significant gain. There are plenty of options out there, some have even killed the notorious torque dip with UEL headers and a tune. Lots more info on Ft86club for this platform.

MotoIQ did a test with Royal Purple octane booster, it added some power.

Moto iq also did an article showing any mods to a BRZ are a waste of time on the factory ecu. For whatever reason the factory ecu adjusts the tune to make less power even after the car has been pro tuned.

This is the stupidest bull**** ive ever heard.


These cars desperately want to make power.
And theyre very good at doing so

The stock ECU is very capable, its a very similar ECU to the EJ series motor ECUs. In many ways its better.

Its faster,
It doesn't do anything "on its own" as you suggest. (aside from pulling timing in the event of knock)
Its more powerful (on the fly map changes, intelligent limiters, etc)
