Stock one comes in forged and cast varieties, but with 6 bolts. So more machining work for high power builds to pin and/or add extra bolts.

And the added bolts/pin ups the power capacity? Do the factory flywheels/etc slip on the 6 bolts somehow?
On the V6 in my car there are only 6 bolts but GM didn't even use a pin on the end of the crank. Guys make 500+ hp with this engine and boost without any issues in that department.

Have you tried fitting your ARP main stud kit yet. I bought the set from integrated engineering and tried installing it on a CBUA engine and on 5 of the caps the nut side of the threads are too large to fit inside the cap and the #4 cap that I did the thrust bearing mod already on has a tighter tolerance hole and the body of the ARP stud won't even go into that one. I installed the stud on the other 5 caps after the caps were in place and they do not seat all the way down and stick up about 3/8-1/2" to high imo

PS: boost brothers are finally taking orders for swap kits again, I’ve got mine on order.

RMM, I purchased the integrated engineering ARP head bolt kit ARP-CVB1 and that fit great. They do not appear to be selling this on their site anymore but a couple suppliers say they have it in stock yet. The ARP main stud kit did not fit right, I ended up taking the block and caps into the machine shop again to have the main caps holes reamed out to accept the main studs.

I commend you for your effort. The ARP stud kit I’m returning is ARP-CVB2. I installed The head bolts (Victor Reinz brand) I bought locally from Advanced auto supply and they fit fine, and torqued well, I could “feel” the stretch as I turned the last 90 degrees. Not fancy like ARP studs, but hopefully will hold for the moderate boost levels I’m planning.

I contacted boost brothers and they said if I bought now maybe by end of year they can get a kit for me.. So it looks like I'm going to fab up most everything..luckily I am a welder and I have a 2 axis cnc mill and a couple of lathes. Nothing internal engine wise now. It may eventually end up in our lemons 944... but that's way down the line if ever
I"m modding a 02m tranny to make the adapter to the torque tube. I'll have to mod the oil pan like people have.
The oil filter plate I am going ro maybe tap the block and run an fittings. Block the water lines there also. Make my own rear water neck and vacuum pump delete
Not sure what to do with the water pump yet. Need to do some more research.
No power steering just an alternator needed. I am going to make my own plate valve cover.

Since you’re not waiting for the BBG kit, Quicktime makes a bellhousing that available immediately, deeply discounted now makes it reasonably priced.

From what I can tell you are correct. I'm not sure what to do with the oil control valve, may need to just leave it unplugged.
1 - Yes
2 - Yes
3 - Blue --> oil pressure switch
4 - Brown --> reduced oil pressure sensor - supposed to go from open to ground between 42-31psi
5 - Black --> I believe is the oil control valve for VVT
6 - Yes
