Questions about possible manifold and dp change

Hey guys so I have Begi's cast manifold and begi-s downpipe and was thinking about replacing with a nice ss manifold with an ewg and getting a bigger diameter dp as well. I just ran my car at Begi's dyno day and ran 241hp at 9.75psi on a rough tune and want more of course. I also have ac and power steering and that seems to limit my options if I were to have one built. Not sure if the benefits will outweigh cost though. My spool at the moment is awful and I have a garrett actuator waiting for me at my house to see if that helps but if not it seems that either I put a restrictor in my intake/exhaust or go ewg. Thanks for your guys input!

Well I know that my 4.3 isn't ideal but until I find a good deal on another it'll work. I would like to have 5-6 hundred horsepower from a v8 but since I don't have the big stack of cash and time to throw it down I can slowly build a better and better turbo set up until that point. Main reason I am considering this is because of my terrible boost creep. If the garrett actuator helps then ill /thread but if it doesn't then it seems ewg is the only worthwhile way. I was thinking about maybe drilling into the cast manifold and welding some weld els and an ewg flange on just like Begi's cast ewg. Then I could probably make a 3" downpipe with the help of my father for the welding/pipe bending skills.
Off topic but hows the fitment with people's 3" downpipes?

Port the wastegate if you're having boost problems. I was having them when I got my new turbo and ordered a new houst housing from BEGi and had them port it. Never had a problem with my IWG setup and creep since then...and running 14psi on a 2560R. IIRC BEGi does it for free/nearly free.
I was kidna joking about the 4.3....but am half serious. I don't thinkg you have a problem nearly breaking even doing a sell/trade for that 4.3. You'll be much happier with longer gears.

When I first got my setup it was overboosting to my 15psi overboost with no signs of stopping so I ported it via begi's instructions and now the peek boost is 9.75 but the problem is how long it takes to get there. I should be reaching max boost with my tiny turbo at 3000 or so but I'm at like 5 or 6psi at 5500 rpm and it creeps up throughout. And I agree on probably breaking even on the 4.3. It's just as this is my only car I can't really pop it off at the moment.

240rwhp @ 10psi with 2560 is on par with a good setup. If your tune was 'rough', you should be able to pick up even more and be happy. I was at 245 @ 9 with my tubular BEGI replacement mani and full 3" exhaust (IWG).
Spool shouldn't be a problem with any manifold on a 1.8 and the 2560. Focus on the actuator first.
