Frustrated with forged bottom end H/C results.

I like my BTR stage 2 with ported 243 heads. Pulls strong all the way to 6800 rpm. Cam Motion Titan 2 would be another cam to look at. I made 400 rhp with a Dorman LS2 intake on a dyno a bit on the low side compared to what it normally reads.
I don't think there is anything to be gained with a MSD intake unless you are spinning to 7500 rpm.

I have the same cam and ported 243’s. I also have a dorman ls2. So I guess my assumption of about 400hp is right. 4000lb car with me in it trapping 113mph. Stage 4 cam is just way too big. For that motor. Unless it’s in a super light car, but a big stall and gears. In other words everything should be tailored around that. Still should have made more hp tho.

Thanks for that info. Now talking about the cam, which cam could help me reach 450hp or get as close as possible, after I figure out the fuel issue of course. Do you think the 228r will be plenty for 450whp, or will I be better calling tsp for a custom cam? The car is not a daily driver, drive it around twice a week. Any other info on supporting mods you can give me will be appreciated. I know youre one of the wise guys here.
electric water pump, ATI pulley, power steering delete or turn1 pump or electric steering conversion, insulator under the intake, light clutch if its a manual, behind the headers go to either a 4-inch merge or dual 3", vacuum pump, crank scraper, tensioner delete, maf delete
FWIW -- I hit 490's on a 227/235 cam and 530's with a 237/245 cam through a T56 and 4.30 geared 9" rear. But that was with the best possible heads AND every bolt-on listed above AND work on the driveline for efficiency, such as CF driveshaft, bearing upgrades, etc. There's a whole really long thread on it, if you have about a month of spare time, but documents everything including the pain I went through and the mistakes I made. Link in my sig.
Bottom line, if you decide to keep your current cam, the heads are mismatched for the cam. If you want a fun DD, a smaller cam with awesome heads is a blast to drive with a nice broad power curve.

It will carry better past peak with msd and peak should shift to the right.

it moves down the road effortlessly. I put a low mileage 06 rear and driveshaft in it, which is a slight upgrade. I destroyed the stock 04 smaller driveshaft before I put the turbo, the 06 is beefier. I have done no first gear launches because it just spins. I’ll have to see if I can get it to hook at the track. If not I’ll look into getting some Mickey Thompson drag radials instead of the nto5r I have. Then I may need to get some shocks better suited for drag. But yea, it pullls really really hard on 6psi.

Guys thanks for all the replies and sorry that it took me long to post back. Been busy! I got 2 good news!
The first one is the injectors were 45lbs, not the ones on my buddy's car that were 850cc! So tuner was right. I'm happy about that cause I want to keep trusting him, he live like 5 mins from my house. News #2, this will change the thread completely and I think it will be better to just open a new one on the right section with a bunch of nice pictures. Ready? I have been talking to Jon from Huron Speed Products through facebook and I'm getting a V3 Turbo Kit at the end of the month, joining the DARKSIDE! With that said I'm keeping the LS6 manifold, changing the BTR stage 4 cam for something like an LS9 cam and getting bigger injectors. This will be my first turbo car, so I'm not trying to make 800hp right away. Goal is 600hp, get used to that power level, see what breaks and what not, and step up after that. I'll be posting the new thread soon and I hope you guys can help me, specially FI guys. Again, thanks a lot!
