Default What to buy?

So I have a '94 coupe with Corsa cat-back and cold air induction, everything else stock. What should I get next? Debating between:

1. 52mm throttle body
2. JET tuning module
3. pulleys
4. front/rear power couplers

Anyone recommend some of these or are there other things I should consider? Looking to spend around $800.

1.unless yours is real dirty with buildup(which you can just clean with TB ckeaner)wont do anything noticeable for a stock engine
2.will just make your fans come on earler
3.will free up alittle,just not worth the $
4.if you are talking about the bellow that goes between the mass air,and air intake,unless yours is ripped,it wont do much of anything.

Auto, stock gears (3.07s?), 34.7K miles, haven't had it tuned so don't really know.

Cold air induction is from SLP. I've only had the car for less than 2 months and am looking to boost performance for the occaisonal stoplight...not looking to auto X or drag it (well, may try this once to see what it's like).

Would headers be extremely loud??

Hopefully this helps!

go with 3:73 gears and 11 inch grand sports wheels, you won't believe how the car will wake up, my brother did this to his otherwise stock '93, it really launched hard.

best bang for the buck.....no question about it !

headers will set the stage for a cam upgrade and ported heads, which is probably all you'll want for a dd LT1.

As for loudness this is impossible to comment on, as its purely an individual decision. I'm very happy with plenty loud

I agree!! I can't vouch for the gears, but I will definitely attest that going to 11" rears with Nitto drag radials was the best "bang for the buck performance modification" that I've done to date. My 60ft times are consistently 3/10 - 4/10ths lower since the change (I was running Michelin Pilot Sports wrapped around the stock 9.5" wheels before).

Many people with auto LT1 cars have put in a better torque converter and lower (3.73 is the lowest you can go in a auto I believe) gears and said it was like night and day.

I would recommend 3.54 gears and a 2400-2600 stall converter. But unless you do the work yourself, it's going to run you more than $800. Long-tube headers would also be a nice choice, and they won't make it that much louder, depending on what exhaust set-up you go with.

Thanks for the comments.

So I'm pretty much hearing gears as being the best upgrade. I looked into it before and know they're about $1100 pre-installation depending on where you find them. What should I expect to pay to have someone put gears in?

And how do I post pics of my car/put them in my avatar? Sorry I'm a noob on here.
