Estimated HP gains - bolt on mods and reflash?
 

Guesses as to the Hp gains from bolt on mods here are mine:

CAI, headers, and exhaust = 8-12 Hp (total)
reflash = 10-20 Hp

Total safe increase = 18-32 Hp.
That's my totally blind guess.

I/E/Tune = 237 crank hp 93 octane

Just instake and exhaust with tune? i dunno about that from 197hp.

I'm thinking...

Intake - 4hp
Headers - 8hp
Tune - 12hp

Tho I'm hoping that the 86 is extremely choked up from factory and aftermarket mods will show real good improvements

EDIT: Already have some decent headers on it

FIXED!!!!

I remmeber reading some post here back in 2009 that toyota made a statement that this car will come with ~230hp, but then they detuned it for less greenhouse gases and better mpg!

I really feel the FT86 is capable of +30hp with only I/H/E and tune...

time will tell :)

Now if we go FULL bolt on route...

Intake

Throttle Body

Intake manifold

Headers (equal length...will lose rumble..)

secondary cat delete, replace first cat with high flow

2 1/4 inch tubing (to maintain low end torque a little bit)

A nice high flow muffler

BAM should get 25whp..with a tune and all that

Some people consider cams as bolt on...but they typically lose torque on the low end. But 30whp should be attainable with I/T/IM/CAM/H/E/Flash

The headers are already equal length, there will be no rumble at all from the factory.

O sweet! Thanks! :party0030:

No I know what I said, and I stand by it. We will see when the aftermarket comes, but I think this car is seriously detuned...

Agreed, the pictures of the engine outside the car show a large cat so I'm sure there will be room there for a good set of aftermarket headers and exhaust. As per usual on Japanese performance cars there probably isn't much left on the intake side. Also looking forward to what a tune will do for the motor.

Ill put my money on 220whp after all "bolt-ons" and tune. But we shall see

i would speculate it is detuned. Car companies have already made engines with 200ps/150lb torque. but with gets less then 30mpg.

They are speculating that the car gets over 30mpg. i think tune before bolt ons, we could see 5-10+ hp

all that for 25whp? i got 35 from I/H/E/ highflow cat/ tune on my 1.8 celica

a correct IM for my car yields 15 whp alone
throttle body give my engine another 4
lager exhaust gives about 8% on top of that
cams gave a nother 8% gain in hp -2% loss in tq
