Most effective ways to make a "fast" NA car

[StormTrooper]

30hp means a lot more to this car that it does to say a g35 or any other 3500lb plus cars....

Going from 14. 5 to 13.9 in the quarter mile is pretty decent....

do you really think this will make a difference? is this just another air intake or am I way off. Who is FBM?

have we forgotten the true nature and purpose of this car? It was not built for speed but for it being nimble, quick and amazing with turns. Being rear wheel drive, 6 speed and weight ratio makes it such a pleasure to drive.

If speed is what you want get an older WRX or something turbo.

yeah... they said that about miatas too. then people started putting turbo's and v8's in them, and suddenly it wasn't so much about that anymore .

really that's just a cop-out. the car's slow because it had to be cheap.

[krulux]

There are plenty of cars that can torque their way to 60mph or rifle through the quarter faster than the GT86... and they are usually more expensive or lack in the handling department or both. Of those that do come to mind, only a handful are what I'd want to take a 35mph curve in at 85mph as I can in the GT86.

That said, our cars are not slow by any stretch of the imagination. I'd wager the GT86 is more car than most people could drive/handle at 90%+ of its performance envelope.


And for an old guy like me ... the GT86 is a rocket when compared to what I grew up driving/cruising in... (Taken from HotRod Magazine)

the tune and header alone will beat a ap1 with intake and exhaust. ive ran two of my friends with just the revworks header and a catback and im ahead 2-3rd gear 4th they always leave. but the oft tune makes a big differance and im only on 93. e85 is 200whp

[GT86meMR2]

the 86/BRZ has enough potential to be faster.. it's just a matter of adding more WHP and I don't think that's even a hard thing to do nowadays.

You can find this in the fi section.

These cars are all about driving enjoyment. They are fun to drive because they are so responsive - a good tune on E85 goes a long way to making car MUCH more fun to drive... it doesn't make the car *that* much faster but it makes the engine/throttle much more responsive. Other things like lightweight flywheels, lightweight driveshafts, final drive swaps will all make the car feel much more responsive, but not really make the car that much faster.

If you want a powerful 86, you gotta go FI.

Seriously this.

When you said fast I immeadiatley thought about track. As if you wanted speed in a straight line you would have gotten a different car really.

[Jesse@JDLAutodesign]

A good tune/header really wakes these cars up and makes it feel quite a bit different than stock. Fast...well that's relative. One of the fabricators here drives a Honda Civic hatchback that makes well over 1000whp, yet even he was still very impressed driving a stock frs back to back with a tuned/header/e85 frs...

Yes! Thank you for saying what I could not articulate.

I should have named this thread "how to make an even more fun NA car"
Or
"How to make a respectively quicker NA car"


I totally could have purchased a wrx or a mustang if I wanted more power. But I enjoy this car too much. I wouldn't want to sacrifice everything this car is amazing at. To be honest I want to have my cake and eat it too. Luckily around 30-40 more horsepower and the shorter final should do the trick

I'm not planning on winning any races.

Fun is definitely the top priority

"Soon"... My bet is we won't see anything for at least 6 months.

My best advice for building a fast NA car is to wait a year and see what internals are on the market then. Still, don't expect breakneck speeds or anything. I imagine it will top out at around 250whp for a fully built NA engine. That would still be very impressive and a lot of fun to drive, but you won't be beating Mustangs at the drag strip.

For now, my advice is that a header and tune are a great place to start for an NA build, as that's where you'll see the biggest gains. The stock intake is already very good, but feel free to go for a Perrin CAI if you really want to squeeze out every last hp (I'm talking like 5hp at the peak), and a full 3" exhaust would be good for a few extra hp on top of the header.

I seriously doubt most drivers could get their frs/brz into the 14's. The 14.7 these cars are supposed to run is with a professional driver on a well prepped track with perfect conditions. I think 14.5 is about a second faster than most owners are gonna run in the quarter. The best mod is a driver mod.

Or is a +80 whp gain possible as campy suggested.... If a +80 whp gain IS indeed realistic NA, then there isn't much of a point in buying some of these stg1 s/c or turbo kits eh?

Hp/$ without F/I is very expensive. So yes there will still be a reason to buy FI for who wants more power and doesn't have big pocket, plus daily drivability sometimes can be affected in very modded N/A build.
