Advice needed. 300 single turbo

The cam is only about $250.
I don't see any blow off valve or wastegate.
added.
I don't see the EFI system including sensors and cable assemblies.
hoping to get a parts truck for that stuff.
Don't see the Scorpion 1059 roller rocker arms. (If the head is 1985 or 1986)
added.
The pistons will not be standard size.
They will be at least .030" oversize.
Your machinist will determine the piston size.
ok. was just going to tell him as small as possible to make the bore round.
Do you already have the turbocharger?
no.
What did you decide for an intake manifold?
parts truck.

Because you are looking at using a stock head, the turbocharger should have a compressor inducer in the 55 to 57 mm range.
The focus needs to be in the area where the stock head breaths best between 1500 and 3500 rpm.

The turbocharger you posted has a 62mm compressor wheel which is too big and will be a mismatch for your head and cam combination.
Here are some suggestions.



If you want the turbocharger to spool faster and have more power at the low end of the rpm range.

Any of those three will work.

If you want the turbo to spool faster and make more low rpm power, then select one with the 0.63 A/R turbine housing.
If you want more power at the upper end of the power band and are willing to trade off a little turbo response at the low end, then select a turbo with the 0.82 A/R turbine housing.
 
Injectors I found are GM injectors rated for somewhere in the 54 lb @58 psi range (12609749), would these work or what injectors would fit? that would have more in the tank if I increased the fuel pressure?
What would fit? That depends on your project goals. Please post that list up, as we could design a perfect combo but for the wrong results. That can quickly become a waste of time and money. However, it can also be a springboard, but in that case go easy the first round.

The 54s could work, but are oversize, and capable of around 500hp at that rating. Yikes. Realistically, you're not getting there, and parts are like shoes - you can run best with the size that fits. Even at a lower pressure, they're still too big. Those injectors would flow about 45 lb·hr at 40 psi. Given your desire to use low-octane fuel, I am thinking you will not use the capacity of those injectors, and so they will be a liability for control at lower loads and speeds. Everything is a compromise, and there are workarounds, but if you compromise too often it will bite you.

Unless planning a method to suppress detonation, you won't get that much out of the turbo setup. The stock head is an ancient design, and not particularly suited for high effective compression. If not higher octane like E85, then perhaps a water injection setup. In any case, unless you control your det, you won't be needing injectors that large. A good range (assuming a lot with no goals), would be 34-40 lb·hr for 350-400 hp on gasoline, for more than double the max factory horsepower and torque ratings. Other opinions with more info.
What tuning program would you recommend?
Depends on your data system. While it can't do everything, MegaLogViewer can read many types of log files, and better, it can do analysis on them. Scatter plots, histograms, and of course data traces to see how each parameter plays into the results. Even little things like overlaying of two runs, to compare where each was better, is a big deal to tune better and quicker. That's very important with a power adder setup for power potential, but especially reliability.
More details on the coil packs option? I need some part numbers or links.
Coil packs, coil-on-plug and similar stuff are options, if you will be adding a crankshaft wheel and sensor. So if considering that direction, start searching for options to get that trigger wheel and sensor on your crank or damper. There are other options to get there with some systems, but the crank wheel is most common, and the majority of systems can use it.

Too expound on this a little bit, a very common aftermarket coil to use in performance applications with individual coil packs is an IGN1A coil - I got mine through DIY Auto tune. If you go this route, you'd need a ECU that can run it which is where the MS3X comes in - You need the expansion board if you want individual coil control.

Yeah, for this application some common coil packs or coil-near-plug are fine. Some like the CNP-style LS coils along the valve cover or side cover, others like 2x3 or 6-pack coil packs on the side or even on the fender apron or firewall. A zillion choices for what you think plays well with your vision or special requirements. Go to your favorite site or search engine and enter "V6 coil pack" for ideas. Part of the problem with suggestions is that there are so many choices for coils.

Random example of the popular GM D599A "smart" coil pack:
GM D599A V6 coil pack.jpg
*"Smart" or active coil packs have internal power transistors (drivers), so external ignition modules are not required. Passive or "dumb"coils (like your old stock coil) require a driver, either in the ECM or external. No big deal, but another thing to put in the system. TL;DR - a smart coil is a dumb coil with a driver built-in. A passive 6-cyl pack will typically have 4 pins, while an active coil like the D599A will have 5 or more.

The IGN1A was originally a marine application, is a huge coil designed for long dwell, but can certainly work for most anything at lower power and directly controllable by most any aftermarket ECM from the sub-$100 EFI ECMs to crazy expensive ones. Considered overkill for most things, but certainly capable of firing most anything. Do your thing.
