LS-ONE_DAY

Ok guys I have a pretty set plan for my car. Current mods in sig, it is an A4 with 2.73s. Obviously I have some other stuff planned than what is below (SFCs, Shocks, etc) but those aren't included as what I need help with are the 4 high value mods.

I will be getting a 3600 FTI converter before Summers end. After that I plan on doing a camshaft swap, a 228R or a custom one, a nitrous kit (for a 75-100 shot), a built rear end, probably an S60 with 3.54 gears including upgraded driveshaft and TA, and a built 4L60E.

Question is, what order do you guys think they should be done if it was you?
Cam -> Rear -> Nitrous -> Tranny, Cam -> Rear -> Tranny -> Nitrous, Nitrous -> Rear -> Cam -> Trans, etc.

Tranny, rear, Cam, nitrous

This is how I would do it as well.

Tranny cam rear nitrous. Only because you're an a4. The rear should last without the extra strain of a manual trans.

Yeah. I'd say cam and rear are interchangeable. Esp with a 3.23 gear.

He's got 2.73s. But if he gets a converter that will help a lot.

converter, sticky tires and a 200 shot!

My bad. I'm dumb lol. Even less chance of breaking the rear then.

TransAmWS.6

Tranny, cam, nitrous, rear. Tranny would be what I would be most concerned about, the rear should hold up pretty good considering that it's an A4 and your mod plans aren't really too radical. So, that would be the last thing I would worry about.

Hmm interesting. I'm not sure what tranny company I would go with, probably a Performabuilt level 2 which runs $1800 but then I'd need it installed so there would be a good amount of time between the converter next month and being able to do that. I think the FLT and RPM options I was looking at are even more expensive.

I know a lot of people say build from the back of the car to the front but having the 2.73's will help even with a 3600 converter. I guess another good way to look at it that I really didn't think about is if I go with a cam first and the tranny breaks I wouldn't have money to fix the tranny I guess it would make sense to do that first if that's going to be the weakest link.

Hopefully in any case, the converter doesn't damage anything or get damaged itself so I can just swap it over to the built transmission when I get it....

having 2.73's will not help.

LS-ONE_DAY

From a strength standpoint I think their the strongest gear for the 10-bolt. Not performance wise but reliability and most sturdy.

I wouldnt touch the motor till you get the trans/verter in along with the new rear. The 2.73's with a 3600 will feel loose around town. If you get some nasty wheel hop youll break any 10 bolt with any gear in it.

Id do the read end, then the trans/verter at the same time obviously and hit the track and youll be surprised. Not sure what gear ratio the S60's have, I have 3.89's in my MDC 9" and love it.. So, maybe think about getting a taller gear as it will make the 3600 stall feel like nothing..

LS-ONE_DAY

Well for the rear I was going to put 3.73's in the S60 but I think I'm going to instead put 3.54's in it. I don't think the loose feeling is honestly going to be all that bad. I've never had a stalled A4 before but FTI makes custom converters and their 3600 stall comes with a tighter 1.8 STR instead of something like a Yank SS3600 which has a 2.5 which adds to the loose feeling. Plus 85% of my driving the car would be highway or with the converter locked so I definitely want to do the converter first so that it has more get up. It's on street tires right now too but I'd probably have to get a set of DR's, probably just 555Rs.

transmission. (FLT, RPM, and jakes performance are great choices) they have 4l60's that can take 700rwhp-800rwhp for quite a while. 4l80 is the ultimate solution if you wanna go ahead and tackle it.

cam 228r @ 112lsa or 114 if you plan on adding a blower one day.

rear--- 9''

nitrous. Harris speed works makes an affordable kit.

that rear will hold long enough, but when the TQ of that nitrous hits....BOOM! . that is the more fun way to do it. pinion seal might leak. flashing the converter will be better than shocking it of course for the time being.

LS-ONE_DAY

I planned on an FLT transmission most likely. Won't be going much over 500rwhp if that. No plans for a blower at all, just the nitrous. I originally was going to get a 9" but the S60 is more affordable so for that reason I would rather just get an S60. I was also planning on going with a Nitrous Outlet total package kit. I've heard mixed reviews on HSW.

FLT you cant go wrong.. I have ~60 bottles of N20 thru mine plus tons of hammering on it.

LS-ONE_DAY

Some people have been saying that the stock 4L60E could still last a while if I did cam first then the trans then rear/nitrous...

TransAmWS.6

I have heard some people claim that their 60E detonated on them with their stock/bolt-on car. You just have to consider that a large part of how long it will hold up has to do with your personal driving habits, the current condition of the trans, etc., etc.

LS-ONE_DAY

I put 50-100 miles on the car per week in a typical week. I try not to drive it really hard. It has 26k miles on it. Mostly all highway and/or 40+ mph cruising. I'm sure with the converter I'd probably want to have more fun from a stop but my cheapness when it comes to spending money make stop me since I won't want to be buying tires constantly
