Need knowledge n advice to build my stock black top

[SENOR_KO_ROLLA]

I want gain more HP/torque. If I envest on some aftermarket pistons, valve spring,cam, camshafts ,rods,bord the block ,port n polish the head n chip the ecu will the gain of the Performanse be worth the investment Or should I go turbo I have a ct26 or ct something lol turbine laying around my garage but I was told I still need to take the block apart to put some low compression pistons ......if u guy can guide me or provide some good solid knowledge I will appreciated .....thanks

This is always a question completely relative to you. It's much easier if you tell us your budget and power goals and then we could tell you how reasonable and how possible it is.
IMO the answer is generally no. This is especially true wit the 20 valves. They are already so high strung from the factory you will not net the same gains as the same mods on 1 16 valve.
You can bump the compression a little more and bump the cam size a little more to get just a little more power out of it. You can't "chip" the ECU. You would need to get aftermarket engine management and learn to tune or pay someone to do it for you. The rest of your above mods will be spending lots more money to gain very small units of power.
A turbo is always going to murder an NA build when it comes to dollars spent to HP gained.
You can run low boost on the stock BT but it requires cereful tuning and very attentive monitoring of the systems.
I am running 7 PSI on a stock BT. I monitor AFRs, knock and EGTs so I am able to see if something is going wrong before it does serious harm.
I am hoping one day I can get my engine dyno finished and get the motor on there so I can really push it in a controlled environment and see what the stock internals can really take.
Just going off a gut feeling I'd say 8-10 PSI would be really pushing it but with a good tune I am pretty confidant it could be a reliable build. At that power level the motor is an absolute blast though and with the off boost power and the gas mileage you get from the high comp makes it a very awesome compromise for a street driven car.

I don't know much about running a turbo on the BT ECU. The way to go would likely be aftermarket engine management. I have always wondered what the stock ECU could do with proper tuning but you would be breaking your own trail which involves more time, more risk and less help from others.
This thread may have some helpful info just on the 4AGE and boost in general.
