3.73's Or 4:10's?????
Okay my next investment after I put on my Short Throw Shifter (ordered yesterday 
) is gears. I have narrowed it down between 3.73's Or 4:10's (big surprise right). I do mostly city driving so most people will jump to 4:10s. My only concern will be FI within the next year or so. Gears are going to hold me over until then. I know 4:10's will be great; but will I be unhappy once I go FI? I can just imagine not having long enough gears to get the most out of my blower or turbo...
PS. Blowers = Kenne Bell, Whipple, Saleen.
Turbo = Single Turbo. HP Performance.

I would go with the 3:73. Especially if you going to get blown in the future. Do the 3:73 and do a aluminum drive shaft and you will be amazed on the difference it will make. That way you will be perfectly set up for that FI and you will have a smoke'in fast ride. Kenne Bell or Whipple H.O you can't go wrong with either.

I also say 3.73's. I've noticed in these type of threads that the people saying go with 4.10's that have 4.10's and a blower, don't run as low as people who stick up for the 3.73's and have blowers.

RE: 3.73's Or 4:10's?????
why not just get the 4:10s while being NA and then switch when getting the blower??
I am going to do the same with mine,that way I have something to hold me off and have some fun with while saving up loot/
still on the fence about weither not an auto or 5 speed for me but I'd imagine with either or with the 4:10s and tune they would both be as quick as the other...

I went with 20" wheels, they are significantly bigger then the stockers. 3.90's would put me back at the same RPM for a given speed as 3.55's with the stock wheels. 4.10's and the 20" wheels is like 3.73's and stock wheels.

I have stock 17" and 3.55 gears. Planning on 4.10. Now you have me second guessing.[&:]

Just for clarification, it is not the wheel height that will effect the gearing, but rather, the tire height. In other words, assuming the stock tire height is 27" and your gear ratio is 3.55:1, a 20" wheel with a tire width of 275 and aspect ratio of 35 (275/35-20) the tire height would be 27.6" which would make you feel like you have a taller gear (numerically lower). If you used a 275/30-20 tire on that same wheel, you would have a tire height of 26.5" (1/2 inch lower than stock), so the same 3:55:1 gears would feel a bit shorter (numerically higher). In other words, if you maintain the stock 27" height, the weight of the wheel/tire combination is the only variable that will effect how quickly you accellerate out of the hole. BTW, if you maintain the same tire height, irrespective of wheel size: lighter is faster, the tire revolutions per mile will be the same, and the smaller aspect ratio with the 20" wheels will certainly effect driving comfort.
