    So, I recently got a big 16G to upgrade from my 13G and I got it installed it in my car. However I'm wondering if it'll be safe with my setup, which is as follows:

    - Manual ECU
    - Manual 450CC injectors with automatic FPR, so adjusted for fuel pressure I believe they are making about ~470CC
    - K&N replacement air filter
    - stock fuel pump

    Should I be safe to put oil and coolant back in the engine and drive it, or should I hold off and get a new fuel pump and/or an ECU with ECMlink or something like that?

    I drove for about a year on a similar setup, I think I had an exhaust,and a pump rewire. I was getting boost creep, so I'm pretty sure I had an exhaust.
    You'll be fine, maybe run a tad rich. But I never had any issues on stock boost level with the stock pump.
    You could run the manual fpr for now, but like I said I didnt see any issues. I dont really go full or 75% send a whole lot tho either.
    A fuel pump rewire for might be all you need while your saving up for a 190 pump and ecmlink.

    I see. What would benefits would a fuel pump rewire have? I'm not too familiar with it

    Look up the fuel pump rewire, it’s basically running straight battery voltage through a relay to your fuel pump. Usually because it has to run through all the wires and stuff your only getting like 11 volts but with that you get 13 volts. And I’m sure your setup will be fine. I ran a 2.3l stroker on 15 psi with the stock ecu and injectors. I never had an issue and I ran it hard.

    You'll be fine putting the new turbo in. I wouldn't expect it to be fast or anything nor would I push it. The stock fuel pump and maf run out pretty quickly. You start getting fuel cut (really an airflow issue with the stock maf) and the pump runs out of flow. If you just want to put around town you'll be fine.

    You would probably be fine but I would highly recommend getting ecmlink or a good tuning solution then you can data log and make all kinds of changes. Tuning should always be the first mod as far as I'm concerned.
