Boosting Beams, Plans and improvement on those plans Options

[ricochet1490]

I' ve been considering this as my build progresses and it's something I want to do after I get the car on the road.... but something I want to do nonetheless. I don't want a terribly high investment but 200+ WHP would be a great feeling.... and this is where I'm looking for expertise outside of mine....

Internals are remaining factory
Looking at going with a supercharger and I don't really like how "cluttered" the engine bay looks with a turbo .... it also isn't as "peaky" and should be more smooth to the power
My initial thought is that I want to keep the stock ECU so I'm assuming I have to stay at about 5psi or so for this to happen?
I'm frankly not sure what the stock beams ecu can handle as far as boost is concerned. Any thoughts?
What are my best tuning options? I want something that is tunable and the toyota ecu not be able to change it (if that makes sense... these things are smart)
I want to keep the CR stock as well. With a proper tune, and the low boost numbers it shouldn't be a big deal I don't think, just gotta watch for knock
Keeping the boost low like that, I'm HOPING that the stock fuel pump is adequate to handle the increased load...
More importantly the injector size of the BEAMS has been debated. The books say 340 cc while the bench test hat the guy did on Daniels injectors reported 400 cc flat. If they are 400cc, I don't think I'll need to upgrade those either... but again, I just don't know.

My biggest questions at the moment are involved around ECU and the tuning, but any and all help would be appreciated

So check mark on the piggyback. Got it.
Now it should be re noted that 5 to 10 psi is all I'm looking for. Twenty will never happen. Not even 15 I can promise you.
as far as internals are concerned, I was under the impression that the beams and the 4thgen 3sgte had the same rods. Now I could be mistaken, and I know the 4th gen rods are known to be weak, but if they are the same, that would mean at least that part of the engine was designed for boost.

Now with such a low boost number, does a guy even need some form of charge cooling like an fmic?

In a high compression setup you need that air to be as cold as you can get it to be... otherwise knock will kill your engine.

So yes, you need an fmic. If the rods are the same as the 4th gen rods, I'd look into upgrading them before boosting.
