i dont realy know much about engines, but i do however know a little about the elcetrical system, so anything i can do to the engine, tell me, crankshafts, manifolds, honing, etc.

umm... i dont want the srt10 because i prefer the v8 over anything, and the v10 is a little heavier than the v8 so...

im willing to spend anywhere from 12 thou to 15 thou. im already planning on getting the aero 3030 exhaust, a supercharger, a diff air intake sys, and maybe tuner

Scratch the supercharger idea. Check out www.ststurbos.com you will make way more power with something like that. You will also wan a new transmission so go to www.suncoastconverters.com and check their stuff out. Your tranny will not like that much power.

Where are some good places to upgrade your tranny because If I ever get something with an auto tranny I would definately plan on beefing it up just because I don't like the reliability of them. and would want something bulletproof

You're definitely gonna need that sts turbo. That alone will get you over 400 rwhp. The website is actually www.ststurbo.com too, motorider had a typo. Along with that, you would need custom tuning, and some fuel system upgrades. The remote turbo would replace an intake and exhaust, so no need to worry about those. A tranny upgrade to handle the extra power would be a plus, and a new torque converter would give you more power off the line. (Edge and APS make nice ones, I tend to hear of more people going with the APS though.) You could also look at a new camshaft, or possibly getting your heads ported and polished. www.krcperformance.com works with a lot of high power hemis, and that may be a good place to check out. If you're looking for serious power forged internals are also a must, and the possible addition of nitrous. If you have extra cash left, I would definitely recommend getting some better tires as well, the stock goodyears aren't the greatest for traction.
