About the only 4-bangers that continue to use timing belts are the Subaru Boxer's. I personally hate timing belts. The OEM's claim 100k replacements now, but you can never trust rubber over steel IMHO. I still don't understand how that Boxer H4 got the Ward's award while the LNF remains off their radar. Then again, they awarded Ford the award several years in a row for the 4.6L 3V V8 that was based on the 2002 5.4L 3v V8 that debuted in Australia. The LNF produces a lot of bang for the buck and displacement. Fisker and Eflin use it on their specialty supercars but it remains an unsung hero for the most part. I bet the LNF would make a great engine for the Crown Vic, much better than the 239 hp 4.6L 2V V8 that they continue to use. The LNF w/ Stage 2 would also make more torque than the V8.

Is the Neon still a production vehicle? The Caliber uses a timing chain according to some Google searches. Like I said, about the only prominent engine that continues to use a belt is the Subaru Boxer H4. Everyone else has moved on to a timing chain. They are good for 300k miles. Even GM rates the stock timing chain components on the SS/TC good to 1400 hp (tensioner, guides, etc...)

How many pounds boost?
The Cobalt SS turbo does not set a boost pressure. It is looking for a specific torque and will set the boost needed to make that torque. The amount of boost is dependent on weather conditions and what altitude you are driving. Members here can report what they are seeing under specific conditions.

Stock is 20 PSI according to GM's LNF documentation.
However, the stock TMAP sensors are rated at 2.7 bar, so they're good for up to 24.9 psi.
The GM Stage Kit TMAP sensors (also used on Alfa Romeo) 55206797 is rated at 3 bar, or good up to 29.1 psi

I'm new to the site, and need help! 09 SS/TC Stage 1, and I'm looking for good performance websites. Does anyone know of Hahn Racecraft? That's the only thing I've found so far, but don't know anything about them! I was an LS1 guy, but my now ex wife destroyed it.

Can this sticky be "updated" all the information is from 2007. I would like to see the GM stage kit added, along with common mods, turbos, or tunes and what to expect out of them compared to a stock standpoint. A list would be good, so more of the same questions can be avoided.
