quick question on adding a turbo to a 5sfe Options

[b22ri22an]

I read through a lot of the stickies and a few threads but cant find these particular answers

Can you run a low boost say wastegate pressure about 7lbs on a stock ecu with no piggyback unit? Will doing so compromise your motors reliability?

If the answers were there in the stickies and I missed them I apologize, but it seems they just said its recommended but never said it could or couldn't be done without one if I read it correctly.

I'm not looking for tons of power just a little bit more then what i got. I'm about to have my 5sfe fully overhauled and I am considering putting a turbo charger but I want to keep the cost down. I know if I had the piggyback i could get a lot more the 7lbs on stock internals but the piggyback and hooking it up and tuning it is the part I can't afford the rest can be bought and installed rather cheaply (sub 500) and i can always add the piggyback later when I have more disposable income.

you can run the stock ST185 turbo (ct26) using non turbo 7M-GE injectors and a USDM MR2 or ST185 MAP sensor.

on a stock 5sfe ecu? if so do tell more.... like I said I'm not looking for tons of power just more then what I got, I can't justify the piggyback, the cost of install or tune for 20 to 30hp
