Where are you making full boost?
Where are you making full boost? I'm running a GT67 rear mount, a2a intercooled and it seems to take quite some time up into the rpms to spool. around 4.5k is where i'm making 5lbs at.
Car has LT's, and an slp aftermarket radiator so the engine runs around 180 constantly.
Is this normal....first turbo car here..

thats a bit high. Swap the LTs for coated manifolds and wrap the exhaust from the collectors back to the turbo. You can also try going to a 2.5" stock ypipe with no cats and swapping to a .81 a/r exhaust housing. A good boost controller can also aid a tad.
Also up the boost with that forged ls6. I would shoot for at least 8psi, and if you have 317s then 10psi shouldn't be a problem with that meth on top.

Get rid of the long tubes, and find some stocker manifolds, You have a manual so you should have 3.42's... Get some 3.73's... Make sure you dot have any boost leaks
Im running 5psi and getting full boost @ like 2800-2900

Damn you guys making boost before 3k are really making me jealous, I've checked the piping for leaks but can't visually see anything, is there anyway to better check?
I bought the car pre-built, which kind of sucks as I'm not sure how it was put together or if any "short cuts" were taken...
2000turbovert, do stock manifolds as they come from the factory work best, or ported? I'll take a pic of the wastegate here in a bit, but there is nothing over it could that effect it at all.

Yeah, but the people making full boost so soon are running smaller turbos.
****, when I ran MPT-70, I had full boost by 3k rpm starting at 2k rpm...
And that was with 3.73's from my NA days.
Now with the PT-76GTQ it jumped up to boost starting at 3k rpm to full on at 4k rpm, but now I rev to 7k rpm, too, so it's all the same to me.

If it was up to full boost at 3k I would be ecstatic, and I'd be happy with 3.5k
ill log mine today...auto locked in 3rd...3.08 gears...408 with t-6 88mm 1.32 a/r
it spools much slower than the incons did but i am very happy with how linear it comes on...easier to control on the street

Hopefully I'll be swapping the LT's for some manifolds soon. The I pipe is wrapped all the way until the Y pipe, I ran out of ties and time when I started on it.
The turbo exits via a magnaflow bullet right now single out.
I'll recheck myself on any leaks today, but I really did see any visible weakeness the first time I looked, not really sure how to check a boost leak as I would have to be driving it building boost so I couldn't put soap or anything like that on to check it.
