The SSRA is a good proven mod, and yes you will still want a SLP lid to go with it. Also you'd be better off with 1 7/8's headers, 1 3/4's will hold you back some when you add a cam. Speed Engineering has a really good price on 1 7/8's stainless steel headers but they wont ship for about 3 weeks.

If this is just a weekend toy and you don't care about gas mileage I'd get a GOOD (Yank, Circle D, FTI) 4000rpm stall converter, trans cooler, and 3.73 gears. The gears wont gain you much performance but it will feel more responsive at part throttle with a big stall like that.

Since every LS1 makes around ~350hp at the crank, by adding LT headers, catless true duals and an air lid (also assuming tuning for the headers), I think it's certainly reasonable to expect around ~400 crank HP on an '02 car at that point. Without tuning, A/F ratio will not be optimal with the headers, so you'll be leaving potential power on the table. Having said that, if you plan additional engine modification in the near future, it might be best to wait on the dyno tune until after everything is done. The car will still run and drive without a tune for headers, but you simply won't experience the full/optimal power gain of said headers.

-On a side note, I am going to clean the throttle body today. Is there a fuse I need to reset or pull out during the procedure for a relearn afterwards? Do I only have to disconnect the battery for the relearn? Or is a relearn not necessary?
Thanks so much!

You can't use GM gears but aftermarket gears will work you just have to get gears for the correct carrier. But any way you look at it a good 3600-4000rpm stall converter and a trans cooler are the best mods you can do on a A4 car.

Congrats on the new camaro. I was in the same ball park as you, 10k budget, and 7k car purchase. My budget flew in no time, you can never have enough once you start replacing and noticing other things you should replace. While your doing headers, make sure to change your motor mounts with some stronger poly mounts. Youll have easy access with the headers out, good idea to change plugs and wires while your there. I put new header bolts and gaskets too, along with 2 new 02s, a lot of the little stuff adds up quick too. Also, some of my budget was spent on buying a few tools needed to work on my bird. Full exhaust, lid, ported tb and a dyno or mail order tune should get you to 400 flywheel hp.

First thing I did was free mods just to see the difference. Port and pollished the TB, modded the air box, coolant bypass etc. It actually made an outstanding difference but with the money I spent on polishing compound and consumables I could have added a little mpre and bought and aftermarket TB. But I was bored and wanted to tinker with my new toy. Next for my Z is speed engineering 1 7/8 LT e cut outs 3 in Y and a magnaflow cat back system. Around 1k. Then looking for a stall cam and heads. Good luck to you and your F body.
