2.73 to 3.73 Just wanted to say hey to everyone, since I'm new the board and this is my first post.
I just recieved my 3.73s and install kit for the car and was wondering about how much the average install would cost for this job, and what kinda difference I can expect to see. (I know pretty huge, but I like to hear you guys say it, haha). thanks,
Jason

Re: 2.73 to 3.73 Welcome to the board.
Install prices vary but I would expect $150 - $250 for a gear swap, maybe $300 at a dealer.
On an A4 without a high stall torque converter, I would expect .3 and 2 mph in the 1/4.
do you have an HPP3 or something to correct the speedo?

Re: 2.73 to 3.73 A stall converter will probably be next, just a little worried cause I've already been through one trans, and I wasn't even that hard on it. I don't have a Hypertech yet, I seen SLP had a Recalib kit for like 150 and was gonna look into that, but if i can find a cheap used hypertech on here I'll probably just go that route.

Re: 2.73 to 3.73 You need the HPP3 to raise your rev limiter and up your shift points. It will be worth a tenth in an auto.
You might know this but the 3.73's won't work unless you get a new 3-series carrier. (since you have 2.73's). Just call SLP and they can send you one. They were running a special 2 weeks ago for $85. This is an absolutely great price for a brand new unit. It's what they take out of all the SS's and WS6's before they put their Zexel's in.
I dropped .35 going to 3.73's but only gained 1.5 mph. Traction has a lot to do with it.

Re: 2.73 to 3.73 A couple of companies make "3" series gears that fit "2" series carries. I had that set up on a 1996 Z28 and it worked just fine. The only draw back was that the richmond gears that I used were a little noisey. Didn't bother me but might bother some.BTW I'm going to use this set up on my 1999Z after I get my vig 3200 in. 2.73s suck>
P.S.: The price for the differential from SLP is great, I might pick one up just in case I break my rear end.

Re: 2.73 to 3.73 My switch from 2:73's to 3:73's put me in the high 12's on the stock tires, stock stall convertor and just a few mods. Good luck and have fun you wont regret it!!!

I think you need a HPP3 for the computer, I don't think you can just re-cal it. The only thing that sucks with the HPP3 and changing gears is that it will not downshift hardly at all.
Peace,
Craig.
