Got around $1500...
Are you planning on going FI down the road? What goal do you have set for the car?
Depending on the answers to those two questions there are a lot of mods u might want or might not want to do.

I would suggest to get the Crawford headers. Yes they are extremely pricey, but for $1500 you can buy them and get them installed. They were the best bang for the buck I had bought until I went with the TT. Even if you do decide to go FI down the road sometimes, you can still use the headers if you go with a S/C.
About the headers, I gained 22rwhp and 30+ torque. I have the dyno's somewhere but not sure where. They did make the car sound meaner and they made it pull really hard after 3500rpm.
But if you don't want headers, then go with an exhaust, a crank pulley, and save the rest for future mods.

I would suggest an exhaust, some headers, not necessarily Crawford's, maybe some decent headers like top speed so you have $$$ left over for other things, and a nice reflash. That would be a very similar set-up to what I have and I'm happy with my cars performance. Or maybe leave the engine/power mods alone and add some nice coilovers like JIC FLT-A2's I LOVE mine they handle amazing-although you would probobly need $100-150 more for those....

Just a popcharger. I had done a dyno before when I was stock with just a pop charger, and then when I got the headers I did the dyno and gained 22rwhp and 30+tq (not sure on the exact number, I think it was 33).

It just brings the perma-grin back

I think the HP # was like 224 before and 246 after the headers. I'm not sure on the exact torque #'s, but they were higher than the HP #'s after the headers. It was about 4-5 months ago when I did that dyno so I don't remember the exact numbers... I'll dig up and post the dynos when I get home this evening.
Thanks for the ideas everyone! As of now it is exhaust/reflash vs. crawford headers vs. 18" lmgt4...
Can't wait to see that graph!!!

Here you go Alberto and Wren57 here are the dynos (the numbers are a little higher then I stated earlier):
First dyno: Best run at 227rwhp and 223rwtq
http://www.we-todd-did-racing.com/we...MXk1NDE%3D.jpg
Here's the A/F for the first dyno:
http://www.we-todd-did-racing.com/we...MXk1NDE%3D.jpg
Here's the second dyno (this is the one after I added the Crawford headers): Best run was 251 rwhp and the average is 250.
http://www.we-todd-did-racing.com/we...MXk1NDE%3D.jpg
Here's the torque number on the Dyno with the Crawford headers: Best run was 258tq
http://www.we-todd-did-racing.com/we...MXk1NDE%3D.jpg
So in the best runs I gained 24rwhp and 35rwtq. As I stated earlier, I had the JWT popcharger in my first dyno, and for the second dyno I just added the Crawford headers.
Edit: Yes, this was done on a dynojet

Yeah, I did it at two different shops, but both were on a dynojet, so I assume the difference wasn't all that big.
