I just have afew random questions. I was reading that A.I.R pump thread and someone said all it does is heat up the cat. If i was to take it off and have it deleted from my computer would i still pass emissions? Same for my EGR, if i deleted it would i pass?

Also, i posted this in drivetrain and didnt get much of a response. Anytime my clutch is out their is a rattleing noise comming from the bellhousing. I was thinking its the TO bearing but want to be sure before i pull the trans. Last question, i have 2.73 gears now, how much of a difference will i see if i went with some 3.73's? On dry pavement the car barley spins and has good traction on street tires. How much will that change with 3.73?

Sorry for the stupid questions, i just want to be sure about afew things.

 

Allmost forgot, i was thinking of some 1.6 RR's. How much will they help me out with my mods in sig?

 

Going to need some better valve springs.

 

Whats wrong with the LT4 valve springs? Also if my TO bearing is bad what problems can it cause? Im going on a bit of a trip tomorrow and would like to know if i should take a different car. Thanks.

 

You will notice a big difference going to 3.73, most of the manual guys go with 4.11 though. The rattle is probably the pilot bearing, could also be the throwout.....

 

If your TO bearing goes out you won't be going much further. It may also be your pilot bearing. If that is the case replace it with a bushing. This is just my opinion since I have not seen the car in person so take it for what it's worth. I also am in need of 3.73's, it will make a BIG differance.

 

LOL.............there I go being a minute late again!!!

 

If the TO or pilot bearing are bad will it cause any damage to anything?

 

LT4 springs would be maxed out on a 305 with 1.6 RRs, you need something with more clearance (and pressure imo)
