hey, i got a couple questions
1. Would it be safe to run at 16psi for everyday driving on a stock 14B, with an upgraded fuel pump, the turbo has 100,000 on it
2. Would it be cost efficent to just upgrade to a 16G with the bigger pump
3. If im runnin at 16 do i need larger injectors along with the bigger pump
4. 16psi, highflowcat, 2.5"dp, 2.5" exhaust(factory muffler), removed air box= 300HP or am i dreaming
5. one more thing, does anyone know where i can get a quiet exhaust, at least a 2.5" but with the stock sound?

1) It would be okay to run 16 psi on the 14b with a different fuel pump, I believe. I run 15 psi on a 16g with the stock turbo fuel pump, it has been rewired though. Depending on how the turbo has been treated in its life though, pushing it harder like that may kill it, but that's just an excuse for a 16G. Make sure that you get a fuel pressure regulator if you get a big enough fuel pump, otherwise you'll screw up the base pressure.

2) I don't know about cost efficient, what goals are you after? The 16G is a great value turbo, it can bring you very far, is fairly cheap, and fits right in where a 14b would go without changes.

3) I notice you have a GS. Isn't that the non-turbo. I'm guessing you have done a turbo motor conversion? If you have the stock injectors from a turbo car, It should be fine, but I would strongly suggest investing in a datalogger setup, so you can tell for sure on your car, it varies car to car a bit.

4) I'm not sure about 300 HP, That's probably wishing a little I could be wrong, and never underestimate what a lot of good, knowledgeable tuning can do.

5) Nope, I don't.

Hope that helps
