I agree w/ Scott above
In addition to ported wastegates my '89+ 60-1 hybrid was bored for T4 "O" trim exhaust wheel clipped 15 degrees- much more free flowing than stock exhaust side.
BOOST CREEP to ~22psi by 3,500rpm (low comp rotors)
Glad my pop off valve saved engine.
I went nutty on stock WGs porting them to max and externally venting them out backplate w/ 2 1/4" hole, maximizing flapper throw etc.
"Only" creeping to ~17psi (warm day) total now.
I am currently adding a HKS 60mm external WG now (43% bigger area than bored holes I have now).
Save your engine and put a "real" turbo on it- I will soon, I just have to see what HP I can make of "stock" turbo.

oh plus im going to modify the wastegate arm move were the rod connects to closer to the pivot point so i get more movement and also make the wastegate exhaust gases divorced like a previous member did... hopefully with the wastegate opening twice as much and having its own vent will realive all the pressure and keep my boost below 10psi

As I said
In addition to ported wastegates my '89+ 60-1 hybrid was bored for T4 "O" trim exhaust wheel clipped 15 degrees- much more free flowing than stock exhaust side.
Pics of it adapted to 60mm WG in this thread. Still boost creeps
. I think it goes back to Bryan for more clip or "P" trim wheel.

Yes, that exhaust should help keep boost creep in check- as well as a spool-up and power...
The pencil pipe exhaust is not staying on is it? I can't fathom why you would do a large streeport, dangerous high compression, a larger compressor and choke it out w/ a puny exhaust.
