Correct fuel pressure is 43.5psi with vacuum hose off at idle.
In your case, though it will idle real nice, it will mean you'll need to add fuel with the VAFC up top, which is not effective since you'll likley run out of injector up top anyway.
To start your street tune, ajust the fuel pressure so that the std ecu without effect from the vafc gives you around 12.8:1 AF (0.88 lambda) at 5500~6000rpm.
It'll be a lot easier to tune it for good results from there.
You'll need a walbro high pressure pump too... stock one won't cut it as you'll end up with around 60~65psi fuel pressure.
Set IG timing to 16deg with pins shorted before starting.

what would be the benefit of ITB's? from what i understand, is that the cylinder's wont scavenge the incoming air from each other and you'd get better down low torque. but how do they benefit an engine around the top end? and would having longer flute's,ram's or velocity stack's on them help increase the rev range, iv'e been look'n 'round for some but most sell for 'round $900-$1100 mark. @ the moment i'm running a skunk2 manifold with a 71mm throttle body.

after reading a few post in regards to b20 rod bolts,

for the ones that have experience in building these motors, what would you say

a standard b20 swap with a b16 head

replace with arp rod bolts or leave it standard?

thanks

I ran mine with standard head studs for two years. Ran with no hassels. Till i went high compression at 13.0 and rebuilt the bottom end. With a closed deck.

you can run with b18c2\c7 head stud, don't run the bs b16a headstuds

yeh just checked how cheap it is, i wonder how long it will take to get here

[tinkerbell]

i have bought multiple packages from those guys... delivered (with tracking) in usually 7-10 business days, BUT they can expedite it if you need (i.e. 5 days) for extra cost (like 45 postage vs 25)...

however - this time of year there will be all sorts of disclaimers saying that times cannot be guaranteed due to the Christmas period!!!
