When to do bolt-on's

How much boost can a 2g Eclipse run until the intake manifold, tb, turbo manifold, intercooler piping, etc. start to become inefficient?

the 2g has a different turbo than your car 16psi on the stock t25 trubo

as for the rest of it its good for alot of power. it has much more do to do with how much fuel and how big the turbo is and the tune

I forgot to add that he has a TD04 16G.

Sorry i didn't see you asking about the ic pipe as well. that is worthless 17psi on a 14b is the limit that i have tested it to but that will vary on different cars.

that would be tdo5h, if its a tdo4h than that turbo is smaller than the stock turbo it came with. Or equivlant to it. People use the stock 2g manifolds for ever they are very well built and when ported flow very well. If your friend is running a 16g he shouldn't be running to much boost unless he has some fuel mods to run higher boost. I would say no more than 12psi just to be safe.

15-16lbs is what worked for me with a evo3 16g on stock injectors with only a walbro 190lph fuel pump upgrade... That was also on stock side mount though with stock 1g tb elbow so that also limited air flow therefore the injectors werent being maxed out,
but with a similar set up and a fmic and a few more mods and that may be different.
I would just get your fuel set up right and not skimp out on that.
