MBC on a 1gb Talon

[Darrick147]

In the next two weeks or so I should be getting a 1gb Talon Tsi AWD. I believe it has a 6-bolt 4G63 engine in it. It already has 3inch turbo back exhaust and upgraded intake. It also has 510cc injectors and a Big 16g turbo, I will be putting in a Walbro 255 fuel pump in as soon as I get it and an MBC. (also has an aftermarket boost gauge. My main question is what is the max boost can this car run with stock internals?

do you have any way of checking what your engine is actually doing besides the boost guage? do you have a logger so you can see the knock counts? if not i'd invest in one of those before thinking about upping the boost. knock kills engines

With out a Adjustable Fuel Pressure Regulator(AFPR), the 510cc Injectors and a 255 aren't doing anything more than the stock setup.

and also would look into a way to tune it for those injectors

Not sure about the knock. I know it's just running stock boost right now. Thanks for the help. I'll look into all that. How much does an AFPR cost? I know someone who can tune it for me.

I would take a look at the classifieds. You can probably find someone parting one out for fairly cheap.
