I cant help. But I have a question. What crank did you use? I trying to find info on a 4gjs crank in a 6 bolt 4g63. Thanks

rise...Rise...RIIIISE!!! Thread necromancy ftw.

Anyway, I do not believe you'll be able to use a g4js crank in a 6 bolt due to it's 7 bolt architecture.
You will need a g4cs (6 bolt 2.4) crank, or one from a mighty max 6 bolt wide block.

I assume you're wanting to build a 2.3?

There are several threads devoted to this:

but you may want to start a new one particular to your questions, as to keep information in the right area.

Dude you're awesome. Yes, I'm trying to build a stroker. I built a 2.0 with hks 272's 20g an fmic. But it's still not enough. I heard the 4gjs crank was forged so I had to ask. Thanks for the link. Being new I wasnt sure where to look.

Pretty sure all Sirius engine cranks are forged, at least all the ones I've seen are. If you want to go aftermarket, it's easier access for 2.4 6 bolt cranks.

Each car has different condition. so it is hard to tell, to be honest. But one thing I can tell is I imagine that your injectors are very close to their limit or maybe already maxed out, it depends on the afr.
My 2G 2.3 stroker's setup is similar to yours. big 16g, 18-19 psi, 510cc injectors, older safc etc etc.
