are they neccesary for a turbo setup of 300-400Hp?


were can you get them?

 

ARP can make u a set, migt as well get im i guess

 

Nice picture wink I have a block that looks JUST like that tongue.gif

Are they absolutely necessary? No, probably not. Are they a good idea? Yeah. More than a few times the Korean folks have told stories about the cylinder heads lifting off the block on high boost runs.

And if you ever have to pull the head off the block for whatever reason, you don't have to replace the ARP stud for correct torque figures. Stock head bolts must be replaced (or are supposed to be) after every disassembly.

 

hey Red, you got a part # for those? pretty please
I should be safe to assume betaI and BetaII are same specs right?

 

Actually, I cannot guarantee that the BETA II motors have the same stud bore depth as the BETA I. That, and two of those studs had to be custom made (at a cost of around $33 each).

I can find the ARP stud part numbers when I go back to work tomorrow...

 

Red, I know you posted about those ARP studs, like way wya back in the day. I think is was back on TSR.


I was getting around to ask you if you would post them again.

 

I have the Exact part number and will post them as soon as possible

 

Here we go:

"AM 3.800-1LB" Qty 10 (Main cap M10x1.25 studs) $4.21 ea
"AM 4.500-1LB" Qty 8 (Cyl head M10x1.25 studs) $4.62 ea
"Special 6.83" Qty 2 (Cyl head M12x1.25 studs) $24.56 ea

"200-8519" Qty 18 (10mmID, .750"OD black washer) $1.37 ea
"200-8500" Qty 2 (12mmID, .875"OD black washer) $$1.28 ea
"300-8343" Qty 18 (10mm x 1.25 12pt nut) $5.36 ea
"300-8307" Qty 2 (12mm x 1.25 12pt nut) $4.55 ea

The special bolts were not as expensive as I originally remembered. Total cost on all the equipment was a bit over $200 for everything as I outlined above. The "special 6.83" is a 12mm stud with a 1.25mm thread pitch that is 6.83 inches long. They may have a better (cheaper) alternative now...

 

Yeah thanx

 

great thanks bro
