On3 supporting mods?
On3 supporting mods? Have been looking at the on3 kit that loses the a/c. Been reading build threads and doing searches but haven't been able to find a clear list of mandatory updates to safely run the kit. I know the obvious fuel pump, injectors, 2bar but seems there is a lot of conflicting info as far as boost reference regulator, fuel rails, meth kit, timing chain, head bolts. Could someone please clarify the no bs upgrades for a low boost application. Thanks
I would atleast do valve springs on top of the other things you mentioned. I have stock fuel rails/regulator,(truck intake) pac springs, china head studs, felpro head gaskets, ect.

I ran a 255 Fuel pump with 80# injectors for a few months. Was running out of fuel around 9# of boost because the pump couldn't keep up. Went with a Squash system on stock rails and haven't bumped past 60% IDC at all.
You can throw a system on a stock motor, think of the rest as insurance. I swapped out my 243 heads for 317 and threw in some LS9 gasket with cheap head studs just to give myself room for error with tuning and on top of that room to grow.
