If your talking, even thinking about a v6 in the frs, stop that thought and end it right there because your missing the entire purpose and design focus of the car.

V6's are smoother, tend to have a more usable power band, and sound better than any 4 cylinder turbo. And they are almost necessary for bigger cars. They are not a dying design. Now V8's on the other hand... those are becoming increasingly hard to justify.

Without the additional low end torque you will need to shift down farther to get the Umph.

If I am cruising on the highway at 65 you WILL need to drop to 3rd to get any decent pull.

If you are bad at shifting often and quickly you will feel slower. The power band is around 5k to 7.5k. You don't downshift low enough you get into lugville. This motor likes to be reved.

Not gonna lie, FRS feels slow compared to my 91 GTR... The lack of torque in the middle of the powerband is very dissapointing. I always feel silly reving out first gear and feeling like im not going anywhere when im trying to start at a decent pace.

Although, the fr-s is a lot more fun to drive, and around town the power is enough. Never had problems merging or negotiating traffic with it.

Don't buy a FR-S. You want a Genesis coupe. Your idea would not only cause the design of the FR-S to be changed but would destroy the handling characteristics that have made it as desirable as it is.

Maybe pay better attention to your driving so you don't catch yourself in that kind of situation to make a dangerous maneuver? Just saying.

Good point... if you want a 6 cylinder RWD coupe platform, there are already several options such as the Genesis coupe, the 370Z, the Mustang, the Camaro, or some BMW's. But the Flat 4 is what makes this car unique and what gives it good balance. I too originally thought it would be better off with a flat 6 or V6, but after driving it, I don't think it needs that much more power. It really does feel more powerful than the numbers imply and the only thing I noticed was the mid-range dip. But the reality is that in most situations around town, you will have more fun working a smaller engine than putting around a bigger engine.

engine is weak and untapped

tap that ass

turbo, supercharge or squeeze that extra 12-25 hp out of a NA set up, its not hard with a tune and some properly designed parts

Idk... BMW M12 1.5L i4 turbo sure make hellova sound... also TRD 4AG revving all they up to 9k... Sure sounds like pure porn to me ;)

I admit there are exceptions. But it's much easier for a V6 to sound good and also, I think you can always tell the difference between a 4 cylinder engine and a 6+ cylinder engine. BTW, I was just listening to the new Porsche 911 sport exhaust note. :drool:

Are you talking bout 918 Spyder?

No, just the new 911 Carrera with the sport exhaust button. Race car sounds when you want them, modest sounds when you don't. :thumbsup:

But I haven't properly heard the 918 Spyder yet. Is it impressive or does it just sound like batteries? :bellyroll:

Like I said flat 6

Oh yeah, don't get me wrong, flat 6's are still my ideal engine. I just think it could negatively effect the handling and power balance of the car to add that extra weight and power. I'd be really curious to drive one back to back with this car though. But I'm starting to think that I need to just get rich and buy a Porsche 911 Carrera 4 or 4S... lol

roddy 09-20-2012 07:46 AM

As said above, a six would add weight to the front and likely eff up the balance. The boxer 4 works OK, you just need to let her rev. With that said, If I had to have a 6, I would prefer an all aluminum DOHC inline 6 with a crossflow cyl. head.
