Will FI Ruin the Balance of FRS/BRZ?

[ZmZMWagon]

With all the great reviews coming out there seems to be no complaints regarding power. Will adding FI ruin the driving experience and balance of this car?

Yes, turbos normally add about 325-400 lbs to the front end of the car, it will completely change the weight distribution and make the car into a understeering piece of junk.

All you need to do is look to other turbo cars for example:
Mazdaspeed 3 60/40 weight distribution

GTI 61/49

etc. etc. etc.

Since when the hell does a turbo, or even, a turbo kit weight 325-400 pounds???!!!

Yes it will add weight and make the car more nose heavy but it's not going to increase the overall curb weight by 15% like this guy is saying.

Keep in mind also that the two vehicles you listed are FWD. The motors and mounted differently and have a lot more shit sitting up front in order to drive the front wheels. Look at the FD rx7 that carried both the single and TT 13B motor. Nearly a perfect 50/50

You got trolled, TylerLieberman.

Turbo won't "destroy" the balance but it will make it a little heavier on the nose end. More so since most of the tech guys are certain you'll need a front mount to make it fit. I think the weight for turbo, piping, and an intercooler would be closer to 40-60lbs MAX. exactly.

You should hang out in the tech sub-forum. Plenty of good ideas and smarter guys in there.

Lol @ Tyler being trolled.

Nah, FI won't ruin the weight distribution, it'll ruin throttle response... and MPGs.

Nothing a good old "battery relocation" cant fix.

That was one of the worst trolling I have ever seen. 400 lbs for a turbo kit? This guy is insane.

it doesnt have to do either of those things. the problem is that fi is way too vague. if you want to make maybe like 35 over peak hp but huge gains in the mid with a mild coldside or even a small turbo, then you dont lose anything except for maybe adding 30 pounds up front. if you want 600 whp then yeah there are going to be compromised. if the cars components can take the amount of power you plan to throw at it, a turbo kit is going to make less of a difference than a tank of gas as far as balance goes.

As always, "it depends".

Pretty much as a rule, adding a turbo will change [ruin] the throttle response, giving the car a totally different [laggy & boost threshold induced] character. Also as a rule, a positive displacement [Roots or TVS] supercharger will simply shelf upward the torque curve without killing throttle response or fuel economy. A twin-screw supercharger will kill fuel economy, and a centrifugal supercharger will fundamentally alter the slope of the torque curve.

[below is a whole boatload of assumptions, including using a low-intake manifold volume roots blower]
Assuming the chassis currently out-handles the power train, then a certain amount of modest power will not ruin the car. Adding significantly more power will mandate a comprehensive reevaluation of the suspension and braking setups. Exactly where that level lies depends on how the total package behaves and reacts to more torque.
