please help..where to start
 

I first bought a cobalt from a dealer used that was heavily modes at over 400hp to the wheels and fell in love. Unfortunately it ghost rode itself down a hill and is totaled. I finally Got another bolt. This one is an 06 ss\sc. It has a cai, zzp long tube headers with 200 cell catted dp and that's it. The cai was on it when I bought it. Two days ago I installed the headers and dp from the awesome instructions in these threads. I know car basics and that's it ie brakes rotors radiators oil changes. Anything else I've been relying on these forums. What's the next step(s) to achieve 300hp to the wheels with my end goal in the long run to be at 400-450hp to the wheels? I've tried looking through the threads but everyone has their own opinions and I get confused. Thanks in advance for the help.

I'm no expert by any means but I know a lot of people will recommend a turbo swap. Especially since your end goal is high numbers. I'm more of an lnf guy so I do not know a ton about lsj's but I think the m62 maxes out a little over 300hp? So instead of spending the money on pully,tune,heat exchanger you may just want to save and do the turbo swap. That way you won't be buying parts that you will end up getting rid of down the road.

what's the difference
 

Besides the price the hahn stage 3-5 turbo swaps all say 15psi boost and 140whp

Only way to get that much power would be a turbo swap.

What that 400 whp one a tint coat red or red 08 ss/tc that had zzp big brakes a big turbo that was for sale like a little over a month ago?

I can't tell u the upgrades
 

I bought it in 2010. It was a 05 ss\Sc. The hood roof trunk and lower body trim was black.the rest was rally yellow.it had custom black n yellow rims.This supercharger sounded like a jet taking off when I'd floor it. It toasted everything. Audi mustang bmw Subaru anyone I raced got toasted by this car. When I got this car is when I first started doing my own repairs and really understanding what certain parts do. So sorry but I don't have any clue what was done to my previous Balt except cai,exhaust,headers,dp,stage3 super.

what's the difference
 

A lot of replies say turbo swap so I been researching them. Hahn has a stage 4-5-6 turbo swap but each stage says 15psi and +140whp. The only diff. I see is the price from a stage 4-6 is about 1,500-2,000 dollars?!?!?

Make it a lsj-t.

Hey guys I went to auto zone and had them code scan my car. One of the codes says cam sensor something. The other says misfire. Any clues as to what these would mean. The other 6 codes are about my o2 sensors. When my cat went bad I bought the zzp header 200 cell catted downpipe bundle and bought after market ac Delco o2 sensors. They said the catted dp wouldn't throw any codes. But since I've installed it the code has stayed.
