What kinds of gains do you expect with E / I and tune? - Page 5 - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

No offense but I think Miatas doesnt have a good potential to increase the hp output so I wouldn't compare it with the FA20. I think the engine might have the potential likw the Honda K20A so 20-30whp may be possible.

I'm still scared to try to crack this cars' ECU though.

KA20's you could do all kinds of shit too, may bee I just have to wait, as I'm not gonna be the guinea pig.

If I/H/E/T might give roughly 20hp+ then what would be the additional gain numbers adding a TRD/HKS SC?

Grip Ronin · 05-08-2012, 10:44 PM

im leaning toward a sc for the first time. seems less maintenance then turbo. hks made 394whp with the sc.

that wasnt just the sc kit though, they changed a few internal components and whatnot. Realistically you'll gain 50-70hp with a sc kit.

What about a port n polish along with I/h/e/t and SC

P&P isn't generally worth a whole lot. It's more of a 'I want to spend money on a bad bang/buck mod' for most cars. :P

edit: At least for mild builds, that is.

Cams before port work.

The older miatass have great motors for turbo, and the duratec/mzr is no slouch either...

yea that's true. idk what to do about the compression though. its so high for stock and the car comes with equal length headers, that's 2 big power increases for Na applications.

If I were going to modify the car I would start by looking at ways maximize the amount of power being put down at the wheels. Improving the efficiency of the stock engine will bump the torque and HP curves up without any low end loss. A good place to start would be replacing the stock flywheel with a light weight aftermarket flywheel. Follow this with lightened pulleys and a lighter drive shaft. Finally get lighter wheels.

Although you don't improve the power of the engine at the crank, you do get more power being put down at the wheels. Other benefits include better fuel economy, better response, easier heal-toe, less stress on the engine (improved reliability) and lighter weight over all. The only down side is everyday drivability; especially with a sub 10 lb fly wheel.
