So here's what I'm thinking and I'd like to get feedback.
Currently I have the following aftermarket parts on my Redline: Intake, intercooler, exhaust and an oil catch (I'm not sure about this one, it was on there when I bought the car and was told that's what it is, though it doesn't really look like one. I'll take pics of it when I get home to see if you guys know what it is).
I'm thinking (and I'm open for input here) I'll get the Turbo Upgrade Kit from GM and have them do the GMPP tune. Then I'll get the high flow cat from SOLO. I've been told this will put me up to 300 hp and put me around 23 lbs of boost from the stock turbo.
Then I'm thinking I'll do the 5th injector upgrade, and install the Super 20G turbo (set at 23 lbs of boost) and BOV from Hahn.
At this point I believe I'll need another tune.
Here are my questions/thoughts:
I'm thinking I'll get the GMPP tune to give me the NLS feature and the 23 lbs of boost. My question is, can someone who knows how to tune one of these accomplish this without the GMPP tune?
Are there any additional mods I'll have to swap out/install to have a daily driver Redline at 350-400 hp? Are the mods I'm looking at enough get me there?
You wont need the 5th injector until you're at 500ish HP. So scratch that.
NLS only works in a narrow RPM range and with other specific parameters. Just get the 3bar MAP sensors (2) and the plug in play harness from Crate Engine Depot, HPTuners and a good vendor tune. Then if you're interested start reading how to's on the HPT forum if you want to fine tune the setup.
SOLO High flow CAT is a stock replacement and a Hahn 20g will need a non-stock down pipe. I suggest getting the SOLO DP and a drop in turbo like the DDM GT2871, you can even get their tune.
You could probably get way with all of the upgrades with install for $3000 just by going to DDM. Then its a one stop shop and you'll have the least down time!
PS - the GMPP does not give you 300 BHP, it gives 290.

He said GMPP plus the high flow cat would get it up to 300 hp, which is probably about right. Those are the mods that I have done. The GMPP did squat for mine (max boost went from 18 to 19 psi, maybe). The Solo high flow cat did more based on my seat-of-the-pants assessment.

Just an FYI, but both Monadzback and Tony@ASAP graphics are on their second engines with the 20G turbo.
That is not a knock on the 20G, its a reality statement that if not tuned properly, the 20G can easily put out more power than the bottom half of the LNF can handle.
It's something you need to consider in your build process if you go with the 20G as it is capable of exceeding 400whp
If your goal is 350-400hp, then the 2871 is a great choice and will put you exactly in that range without the need to build up the lower part of your engine. It will also bolt up to everything you currently have.
As such, I agree with CDnite.

Any turbo will blow an engine if not tunes properly. Supposedly the engine can handle 23 lbs of boost. Won't that hold true no matter what turbo you put in it? Sorry if it's a stupid question, but this is my first turbo car. I'm learning as I go.

How much an engine can take is really not related to how much boost it can take. To give you an example, 23psi on the stock turbo is not going to move nearly as much air as 23psi on a 2871, 20G, EFR, etc. Therefore cylinder pressures are not going to be as high with the stock turbo at those pressures as it would be with the other turbos, and high cylinder pressures is what causes rods to bend and other bad things to happen. Also the stock turbo at those pressures is going to be backing up a lot of pressure into the head, along with a lot of heat, which is not great for the engine also.
Add E47 and you are right at 400whp [If not a little over] without needing a 5th Injector.
That's fits your exact range in the title of this post.
As far as the harness and your code question.
If you install the Bosch 3 bar sensors, the tune needs to be updated or you will throw Cels.
So you want to install those just before you re-tune.
OK, so I'm looking at the bosch sensors, a turbo (opinions seem to vary on which one would be best), BOV, ECU, SOLO high flow cat (is the DP just a straight pipe or is actually a higher flowing cat?), and tune. Is there anything else I'll need? Did I miss anything?
Is DDM a shop? Where are they located? I'm in NY, but I've been known to drive cross country every so often. As a matter of fact I'll be driving down to FL at the beginning of Dec. I could install all of these myself in like an hour. How much do you guys think DDM would charge to install it all and tune it if I pick up all the parts?
