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

opposer · 07-16-2018, 01:33 PM

After few track sessions I saw that I don't need more than 250bhp on my gt86 - I'm not that brave and skilled to tame 300bhp.

I want to spend not too much money and have 250bhp (on crankshaft, not whp). What is the most reliable solution? Wanna have improvement through all the rev range, but keep the engine rev-happy, like naturally-aspireted, with linear delivery of power.

I don't plan to have more than 250bhp. I will track the car (lightly, no racing tires and suspension), so the config must be reliable under beating. What is the best way to achieve this goal?

If that is your goal you may also want to explore getting the best header and tune you can possibly find. I expect that will be nearly as fast around a racetrack for less money than a supercharger. Not to mention quite a bit simpler.

Dude. SC threads have a billion pages of this info. Go check it out

I believe you can reach just a little shy of 210 rwhp with E85 + header + exhaust and tune. It will be a LOT less maintenance and headache for you down the road, especially on track.

Pick a good header + a custom tune. If you're going for max results and have the budget, ACE + their Delicious tune is probably best. Then flex fuel if you have E85 conveniently available. Then look into a 4.55 final drive mod. Possibly add some intake spacers (Crawford Power Blocks) when you get your custom tune. You'll have a car that meets your goals, especially if you have access to E85. And you won't have any potential FI related headaches.

We don't have E85 in Russia

Ah ok - I still think you could achieve your goals without E85. If you want the next step up and keep the rev-happy linear nature of the motor, then you'll want to look at a Jackson Racing C30 supercharger kit with the stock pulley.

I would try to find a used supercharger kit

E85 flex fuel from Delicious Tuning and a good exhaust like PPE EL or ace header will get you 200 at the wheel 225ish crank. What octane do you have in Russia?

supercharger is the easiest way. I would get a nice linear one like Harrop or Edelbrock.

Aftermarket pulleys will get you there no problem.

250bhp is very expensive NA.
intake, BPB, ace 250-150 header, catless FP, header back, custom tune on 93octane could get you 200-205whp or 230-235bhp. With E85 then don’t use BPB and can prob add another 6whp. To get that extra 15bhp you’d need cams and valvetrain to rev to 8200k and that would be pricy.
Or just toss in a sprintex 210 at 8psi and you’ll be at 225-230whp, header back prob another 10whp
