7A/1ZZ/2ZZ engines were paired to C-series transmissions. 3S/5S were paired to S-series transmissions. BEAMS 3S comes with S54 transmission from factory, plus LSD.
I don't know if the C-series box will bolt up to a 3S engine - maybe, I just don't know.
You can swap the S-series transmissions to an E153 transmission, need axles and other shenanigans. But, while the E series transmission is very robust (supposedly good for 600hp), it is quite a bit heavier. 50lb or so if memory serves me right. S series is good for 200-250hp. You'll never get even close to 250hp out of a BEAMS engine NA, so why bother? There's no point in bolting a Turbo to a high compression BEAMS engine - it would be a disaster. Much better off starting with a 3SGTE if you intend to Turbo down the road.
Also, before you complain about the gears being long, have you driven the BEAMS engine, yet? The gears are so long because the engine revs so high. You need long gears for that engine. You could also swap the final drive in an S-series box, but it is quite an endeavor (I've done it, the whole transmission needs to come apart completely).
Hope this helps.

itb are mainly used to smoooth out idle of very agressive upgraded cams. so larger header, intake n exhaust cams with itb with standalone would be great. your thinking if 4age blacktop in stock form has them why not the redtop beams.

you want sound. make a short ram intake with the filter insulated in a box to keep out heat.

you can find adapters easily and then use 20V blacktop ITBs. Youd probably need some short velocity stacks so you can clear the firewall

You'd need to run a standalone.

You won't see a significant power increase. Youll have a bit snappier throttle response

Yep, the lime green with narrow tip is Cali injectors. The dark green are federal.
Besides the potential vacuum leak, the injectors also have a different flow rate:
CA injectors, 23250-74140, 264cc
Fed, 23250-74100, 228cc

Sounds like you had CA spec car and converted it to Fed spec. First, make sure that you've blocked off the injector vacuum assist tube - it should be a hose running from the back-side of the intake hose next to the TB to the back of the head. If you left that hose disconnected, there's a sizable vacuum leak for you.
Next, to make things right, you'll need to get yourself a Fed spec ECU so that it can drive the injectors correctly. You're looking for 96-97 year ECU. 98-99 won't work, neither will 95 and earlier.

The only injectors that are different on 6GC would be the California vs Federal emissions injectors. IIRC, the Cali injectors have light green plastic, and Fed ones are dark green. Cali injectors have more business going on on the tip, as there's extra holes on the sides for vacuum assist. The Cali head also has the extra port b/w injectors 2 and 3 for the said vac assist. If you did not hook this up, you'd have a sizeable vacuum leak which could very well be causing at least some of your problems.
Other than that, look for vac leaks in general, and/or malfunctioning IACV. Did you use your original IACV, or the new one? If the new one is acting up, it may be defective - try the original one.

Bolts right up! Don't forget to throw in custom pistons, standalone ECU, injectors, fuel rail, wiring, custom intake, exhaust, and you'll be making some powaaahhhhh. Not sure how much more, though, as the stroker 5S crank won't want to rev as well as non-stroker 3S. So you may or may not hit the 180hp or whatever non-beams 3S-GE makes, but somewhere b/w 140 and 180hp is in your future.

Just normal maintenance. If your pulling it out, redo all gaskets and seals. Double check all wiring. Check turbos to see if there is play, install a oil catch can. Then build, boost, break and repeat. I have a 3rd Gen 3sgte and a 5sfte both are fun
