What is the best way to have 250bhp on FRS?

Probably someplace but who knows... however there are a lot of before / after dynos , 0-60 , 1/4mile of various mods and levels of mods. And you can compare that vs stock. In an auto I went from low 8s to high 6s 0-60, not sure what my stock 1/4 was prob low-mid 17s, but I broke into high 14s. with bolt ons, 4.56Fd, and tune on 92octane.

What about WRX engine. It is FA20 with FI from factory.

86 has fa20D 12.5:1 compression
Wrx has fa20F 10.6:1 compression

That is a very misleading review. I am not sure what was wrong there. Probably, at a high altitude both engines were suffering.

True, the numbers are quite low. I posted it to show more how they felt about Tuned vs Supercharged.


I thought the fact that they were split was kind of ironic lol

The most cost efficient way would be cattless Header + E85/flex Tune. However since it seems that you dont have access to e85, a supercharger that comes with a tune such as the Edelbrock will be easiest.

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?

Personally I’d stop messing around and go full aluminium V8 swap with sequential gearbox.

Lol. I wish...

Do a header and tune first. I was surprised at how good my car felt with the torque dip ironed out and just a few extra ponies. Certainly NOT 250hp at the point, but it was way more driveable.
(The FF was great too although ethanol isn’t too easy to come by here)

Great video, however, they failed to show how much faster the supercharged car was over the one with tune/headers/exhaust.

This is how much faster the car is with boost. Me and a BRZ getting our asses whooped by a Vortech supercharged 86. Our cars weren't stock either (headers/exhaust/tune)

Been supercharged for four years now, no regrets! Like the other reviewer said, it's much more expensive, but oh so worth it. If you can afford it, do it.

Think the biggest factor would be what is your current budget? And or future budget?

From the sound of things you would be a good candidate for a lower boost supercharger setup could run 7-8psi at 240whp all day. However this route when everything is said and done probably 7.5k$ for kit, install, tune.

Or a ace header + custom tune setup for roughly 2.5k$ and about 200whp.

However neither option restricts you from the other and they both benefit eachother. U could sc now and add header or header back later or vice versa.

So depending on budget you may want to go header first, and if that is enough or getting close to enough power then u don’t need to invest in sc.

If committing to NA and not SC then a CAI if maf scaled and if no E85 then billet blocks.
A lot of ppl say ace 350, that is best daily driver low / mid range torque. If you want to stay rev happy and have some mid / top end power the ace 250 is a bit cheaper and offers more 4K+ then the 350 but doesn’t 100% eliminate torque dip.

And lastly like I mentioned earlier weight reduction. The first 100lbs or so is free/cheap and can make a huge difference. On stock car 100lbs is about 7.5bhp. From a ratio standpoint.

I warned myself not to come in here. Now I’m getting the SC fever again.

If you haven't already go to the track. You will be humbled...


For me, a SC has been put WAY back on the back of the back burner

[CSG Mike]

An easy way to think of it, is that the Ace is half the price of a SC, and half the gains of a SC, with none of the complexity.

Best of all, you won't outgrow the ace, if you add a SC later; the power, in this rare instance, is additive.
