What is the best way to have 250bhp on FRS? - Page 2 - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

The other option if FI isn’t an option or even if it is. Weight reduction can quickly increase power to weight and you could easily NA get the same ratio as stock weight to 250bhp with some weight reduction. 250bhp to 2774 = 11.1bhp/lbs. 174lbs weight reduction with 235bhp = 11.06bhp/lbs

Most stock cars (200 crank) on a dynojet come in around 165-170whp. A top tier catless header and good custom tune, will get you around 200whp, maybe more. Ptunings header made well over 200. That's on 93. 200/165*200= about 242 crank horsepower based on stock being 200 at the crank. But more than that, it will feel much livelier across the rev band. Power blocks, with correct tune, will fatten up your upper mid range, and only sacrifice a couple hp north of 7000 rpm. Add to that the final drive mod and your car will feel quite perky. Past that, like the other poster mentioned, it gets expensive - better to bite the bullet and go FI, where you can get bigger power (and potentially bigger headaches, or at least more fiddling).

Ace header, Race gas, and tune, will get you most of the way there.

are there any videos in the Net with a race between headers+tune BRZ vs stock? I hadn't found any. I want to compare the income

opposer · 07-17-2018, 10:53 AM

why do the people keep saying that turbo or supercharged BRZ has lower reliability than stock one? I had STI 2005 ej207 st1, didn't have any problems at all.

we have very garbage motors for reliability and power output.

If one shaves weight and adds more power and a 4.56 final drive. Well it's the BRZ version of taking the red pill

Nah.. pulleys won't be enough. He might need additionally the red STI start button and maybe the red belts..

1) FA20 is not engineered for stresses of forced induction, STI motors are.

2) Factory FI systems are typically better engineered than aftermarket add-on solutions.

3) Installer error can have expensive repercussions, vs. a car that rolls off the factory floor with FI.

4) People tend to cut costs and not employ fail-safe measures when installing aftermarket FI.

Risk vs. reward. If you go FI, just make sure you have the funding to rebuild a blown motor. If you don't, and you're satisfied with an incremental bump in power, go the NA route. You can really change how the car feels with just a few simple non-FI mods.

Header + tune + 4.56 or 4.8 FD will really wake the car up.

Don't hate on my awesome red STI start button

250 bhp slightly crosses into the FI territory. 200 whp (230 bhp?) is possible with high-end NA mods. You can do ACE header + tune to reach the high end NA level and continue with weight reduction. But weight reduction is not cheap either. I think supercharger will be the easiest way to reach your goal. You will probably get more than 250 bhp that way. But I am sure you wouldn't complain about it.
