ok well after all your help on my last topic i was looking through my car and found a receipt for a gear swap the owner did and he or she put 3.90s in the rearend now i was just want ing to know now should i keep them or say put 3.73s in b/c I do more highway driving than i do in town and i want to try and get more miles with out going to a 3.23.thnx

[GTsetGO]

keep the 3.90's. I used to do a lot of highway driving in my car and I have 4.10's and I was still getting 24 mpg.

the 3.90's are fine. its not worth spending another 500 bucks to put the 3.73's in... it will take you a long time to make that up in gas.

ok will do but one more question how fats do you drive the highway b/c i try to keep the revs low so i only go like 55 60mph most of the time i dont want to over heat it or tear it up when i'm just driving norm.


oh and i havent told everyone what i have on my car yet so here it goes

C/L upper plenum
i think a homemade CAI (I dident make so??)
under drive pullies crank alt water pump
a mac pro chamber running into duel flowmaster 40s
sitting on 18inchs with sumitoma tires 285 35 rz28 rear,front 265 35 rz18
dont know what the rims are but they have a ZR in the middle of them
also i have a big ass throttle body but dont know what it is.

oh and my throttle is hard like when you first push on it feels like it stuck but then it pops over and everythingis allright i had some one tell me it was vacumm holding it closed but i dont know could be it only happens when its on.

and my abs light is on and I had it scanned but it said cannot connect to it or somthing like that, cant rember.

hmmmm..... not too sure about your last two posts.... did you check all your springs on your tb? there's a thread around here somewhere where a guy had a spring fall off (can't remember where it was sorry) so check that out.

i drive about 70 on the highway (75 when the speed limit is 65) and with my 3.73's at 70mph im at 2100 rpm getting about 25-26 mpg.

why would you overheat? do you have a radiator problem? it's perfectly okay to run an engine at 2500-3000 rpms. they are designed to be worked, so it's okay to work them. you won't tear it up unless you redline it on every shift (even then maybe not if you keep your oil changed).

HEY if they told you that your abs would not connect it could be that your brake computer system is not working. there could be several kinds of things to look at with this problem....if you can read a wiring schematic then you are in good shape...if not just remember the next time that you slam on your brakes that your not going to stop like you should....abs helps your brakes not to lock up....no abs you will skid!!!!...good luck and be careful......later
