What hp should I expect? Hey guys I have an 02 ls1 and an 05 corvette ls2. The block is gone in the ls1 but the top end is good. I'm planning to build the ls2. I'm looking at tsp 228r, ported 243 heads, the ls6 intake off my ls1, and possibly another throttle body. Any guesses on what kind of power that would make through an 02 camaro ss t56. Stock trans and rear end. Also what else would you guys do to get more power at a not so high price? Thanks!!

So you say bigger then 228r? The motor I have has 129k miles. I'm thinking about just trusting the bottom end and building. So I probably need to be mindful of that.
A bigger cam won't necessarily be any harder on the motor than that that 228r cam. How much more power would you like to have?

Verdad Gallardo OP, I'd consider something a little bigger if it were my ride. Maybe something along the lines of low to mid 230's on the intake and high 230's/low 240's on the exhaust. That's just my opinion

Think it'd be a good streetable cam? I was looking at ms4 cams but they require high rev to get full use of power band, and I don't wanna be up there that often. Still learning the numbers of cams and how to determine what I need.
With a good tune it will be plenty steetable, but of course it won't be exactly like the 228 cam. Know what I mean? Realistically you won't need to spin a cam like the MS4 any higher than that 228r to make use of its power. I mean you might shift say 6500 rpm with the smaller cam and maybe 6700-6800 with a bigger cam, but that couple hundred rpm difference won't be an issue whatsoever

Nah for the cost it's not worth porting the LS6 intake in my opinion. Honestly I'd just maybe have your throttle body ported (it's cheap to do) or just sell your intake and TB, and get a used Fast setup

I figured porting my throttle body with a stock intake would defeat the purpose. Also would the 90mm ls2 throttle body fit on my ls6 intake? Lol sorry dude I'm really trying to learn this.
Hey no problem man, we all start somewhere lol. Yes there is actually a company that modifies the LS6 snout to fit a 90mm TB, but I don't recall the name. But again by the time it's all said and done, it's really a better bang for the buck to just sell yours and do a Fast.

Yeah that's probably a better idea. I'd love to have a102 setup.. My car had the stock slp air lid I suppose. I spoke with a dude that had like 10 f body cars, and he spoke highly of my air lid. Black hawk air lid? Says they're supposed to be on trans am cars? Anywho my stock lid should be fine with a fast set? Eventually I'll probably end up destroying my whole driveline if I get to high in power. I read somewhere 500 is about where things start to let go.

Yeah I think those Blackhawk lids are supposed to be more rare or something, but they all flow pretty much the same in reality. Also just so you know, a Fast intake on your setup is really only worth maybe 10-15 hp. Getting them ported offers a few more hp. I've seen this personally
