will there be a big benefit with going to a good cam or no with the turbo thats what i want to know.

 

Depends on your desired RPM range. On an STS kit full boost may not come on till well after 3500 or even 4000rpm in some cases so using a stock cam is kinda dumb when your operating range is 4000-6500rpm.

 

this is true. hell i'm spinning up to 6300 rpm now pulls hard all the way up since a put in the new springs and heads. it use to pull hard then just drop off a little over 6000.

 

Definitely gotta know where you're going to be driving. Me, I'd want a smaller turbo so I could benefit from it earlier on in the RPM range (2000 or 2500-6000). I'd want that for a daily driver. But for those folks living in the 4000-6500 RPM range.....

Hell, I'd always be racing my truck if that was the case!

 

right now its got crap below 3,000rpm anways. its a 4.8 remember lol

I had a reverse split in my f-body...231/226 on a 115lsa from cammotion. I now have a 215/215 on a 114...real old ls1 cam from comp. I havent really noticed any difference except for the smaller cam having more bottom end. If you are wanting more bottom end and pump gas, I would consider a 112lsa cam. Yes it might blow a little boost but it will also help with midrange cylinder pressure and detonation.

 

I always thought that if you want more low end, then you would need a cam that produces low end power. So in your case I would think you would want somthing that goes from 1000rpm-6500rpm like a 222/219 .550 .549 116LSA 111centerline. But I dont know, I'm no expert so...

 

why does it have to be so hard? lol this cam **** is stressful.
