how much boost to run?

[mcammarn]

so im kind of scared on where i should set my boost to.
i have not put my rebuilt motor back into my mk3 yet.
so it has 0 miles on it thus far.
also it has a compostie hg not mhg.

whats safe to run for break-in period and what should be safe for after with running a composite?

list of mods are to include:
hks evc6
hks type 1 turbo timer
apexi intake
upper i/c piping
lex afm
560cc inj
afpr
wideband
3in elbow back exhaust
57trim ct26
mishimoto radiator
arp head bolts
act stage 3 pressure plate with full face disc

Edit: Realized I didn't actually answer your question.
I'd run stock (8psi) until broken in but follow the tips in the thread above.
Once broken in, 12-15psi should be safe as long as it was built well and the head torqued properly.

For break in I would leave it at wastegate pressure.

Then after turn it up to what your fuel/turbo/tune can handle.

So 12-13psi for stock fuel pump.

Not for a 57 trim I wouldn't.

Stock pump will be fine because he has a afpr and a wide band as a fail safe.

So @ 12psi if he's not leaning out then he's fine and if its showing signs of lean then up the fuel pressure a little.

The stock pump should be able to handle this unless its dying out which the wide and will also show.

He might not be on a stock 20+ year old pump maybe a stock replacement who knows but I still think a good stock pump will flow enough.

The ct26 57trim really doesn't flow all that much it's something like 48lbs/min if I recall correctly so at 12psi doesn't take much fuel as something like a 60-1 which flows 59lbs/min or even a bigger turbo then that so he should be fine.
