What is the max hp a stock S4 turbo and S5 turbo can make on a near stock engine and street ported engine on stock ecu.

What is the limit of the stock S4 injectors, S5 injectors?

What is the limit of the stock S4 pump, S5 pump? FD pump?

How good are the stock integral wastegates on the s4/s5 turbos? Any problems with boost creep running bigger than 3in dp's and exhausts.

How much more power can the hybrid stock turbos make?

 

first off, search. You can figure almost all these out
Second, where in KC do you live? I live in Olathe and i got everything you need over here in o-town.

If you streetport, you aren't really near stock are you?
2nd gen NA injectors = 460cc, run stock at 58%
turbo = 550cc, same thang
For a fuel pump, if u get bigger injectors, get a Walbro 255 or so. That's what most people do.

Say what you are planning to do and we'll be able to help a lot more.

 

Sorry I searched, this board doesnt seem to offer as much as the last ones I was on I guess?

Im from north kansas city, gladestone area, but going to school in phoenix az. Ill be back in KC this week for a bit. Pm'd you.
