Best thing to do for a little hp gain

[BLKFRS]

Hello, i just got myself a FR-S 2013 and if i would want to have a little more fun, what increases power if i would put 3-4K in the car..

[SloS14]

Great question. Someone should make a forum dedicated to getting more HP out of these cars.

Welcome to the boards. That depends on what you want to do, but for that budget you could easily do a nice NA build (Intake/header/exhaust/reflashed ECU), or you could go with forced induction and look at a turbo kit or supercharger, but those will be close to or slightly above the top end of what you want to spend.

What do you want to do with the car? $3~4k could get you a lot parts. Minor improvements can be had for waaay less, but again that depends on your goals.

EX: Drop in filter, inlet tube, and crank pulley will set you back < $300 and give you a noticeable increase in pep.

Do a search as people have asked around this topic several times before.

Also: don't forget to invest in some good oils for the engine / trans / rear.

EcuTek tune - ~$1000.00 (e85)
EL Header - ~$800.00
Overpipe - ~ $300.00
Front Pipe - ~ $300.00
Cat-back - ~ $800.00
CAI - ~ $350.00

Total - ~$3500.00

This setup has been proven to get an FRS just over 200whp. You don't have the budget for a proper turbo or supercharger setup. Nitrous maybe but that comes with other, more long-term, residual costs.

There is a TON of information in this section alone on these various mods and their respective manufactures with dyno results and everything. All you need to do is,

Where do you want the additional power? Increasing power mostly in the 3000-4000 rpm torque dip area is a different approach to increasing maximum horsepower. Looking for power everywhere is another approach all together. There are other considerations with respect to noise and driveability.

Innovate is working on a supercharger that's all bolt on with no intercooler for a little over 3k. Should be out soon the last I heard they have stated production already. It will put out just a little over 200whp

In order of my preference of cost and power gains:

Drop in Filter ~$40 (makes a hair less power compared to a full intake)
Pulley <$100
UEL Headers $600-1000 (for torque dip in conjunction with tune)
Tune $1k
Overpipe/Frontpipe with HFC~600
Resonated Catback ~600-800

Don't underestimate tires even thou it wont give power. The car was made to handle, which translates to fun as well.
EDIT: ideally you'd want to do the full exhaust with tune, but if funds are limited I'd get headers and tune together.

Lol, yep pretty soon.

(Note "pretty soon" is a relative term, and in this case it's relative to how long the earth has been inhabited.)

i hardly ever see anyone mention a lighter driveshaft. same effect as the light weight pulley. any problems with this? i had one in my old car (3000gt VR4) and there was a much noticeable difference.

3-4K in Hookers and blow in your car will be a little more fun.

[shu5892001]

for 3-4k, I/H/E + tune

The only issue is an aftermarket pulley that was milled just slightly unbalanced or the hole is off center can destroy the engine. If the factory pulley does this the warranty will cover it. Besides that very slight risk of getting a bad one they do help make the car feel better and climb to the top of the rpm range a little faster.

I have wanted one ever sense I went to the shoot out and got to see one in person. But they have been having issues. I guess it's better for them to find all the problems than have the customers start kicking down their door over a blown up engine. The wait has been a lot longer than I anticipated it would be.
