I didn't notice this until a friend of mine pointed this out to me, but if I'm cruising in 5th gear at 80MPH, is my engine supposed to be spinning at 4000RPMs? At ~45MPH, it's rotating at about 2400RPMs. Now I know this my be a different car, but in the 5SFE auto Camry that I used to drive, 2000RPMs at the highest gear was 50MPH. Anyone else with a GT notice this or is it just me?

it's because the gears are really short. it's the exact same for my manual GT. 80mph at 4K in 5th... I wish 5th gear was a little longer so it could get better freeway milage... but I really like the short 1-4 gears.

That's exactly what a friend of mine was saying the other night. leave the first 4 gears alone, just open up 5th gear a bit more to get better gas mileage. He loves everything about my car 'cept for that li'l 5th gear thing. He's contemplating on swapping the seats in his Integra for celica seats. heheh. Lol. my mom has the '99 Camry that I was comparing the car to. Matt - i didn't realize it till Jose (dual exhaust Integra) pointed it out the other night when I let him drive my car. Jaws4God - I was thinking about doing that for ****s and giggles.  Rangemaster - I've no idea what my gear ratios are. how do i find that out? how can i change that 5th gear ratio a bit to open it? -------------------- -Alex {](O_o)[}

I believe the gear ratios for the S54 are: Ratio Top Speed (w/ 205/55/15 tires, and a 6400rpm redline) 1st 3.285 32.03 MPH 2nd: 1.960 53.69 MPH 3rd: 1.322 79.6 MPH 4th: 1.028 102.36 MPH 5th: 0.820 128.33 MPH Final drive: 4.176 -------------------- 94 GT - Sold -------- 69 Pontiac Lemans - Sold 88 Alltrac - Sold ---- 04 WRX - Sold 00 GT-S - Sold ------ 91 Miata - project/drift car 95 GT - Sold -------- 96 GT - New Daily Drive |

I need to find a long open mile of road to try it on. eggman40 - i was thinking the same thing. i thought these cars were supposed to have pretty good gas mileage...i mean, being a 4-cylinder NA afterall. as for the 6th gear bit, I almost did that once when i saw the tach touch 3800rpm going close to 80. if i hadn't caught myself, i would've f**ked something up. -------------------- -Alex {](O_o)[}
