M20 main bearing studs?

[slow325isedan]

So arp doesn't make main studs for the m20? That seems weird lol, well I need to stud my crank so what are my options? Will studs from another engine work? Need help! Lol thanks guys

No help, but I've never heard of the main journals being particularly overstressed.

Rods, yes...

yes ARP do make a main stud set that fits. you will likely need a line hone though if you change the preload.

when i get home ill check the code on the box as it may be the same as one of the other engines. there is a guy who used to sell them on here

[whodwho]

Same as M5x, should be ARP 201-5000

[slow325isedan]

The engine is being fully built so it is getting line honed, shooting for 6-700hp when done so want to stud the crank lol, if you could check on that part number that would be awesome! And I'll cross reference that part number, thanks guys

[digger]

the m20 main bolts are the same P/N as the m50 ones in real oem so whodwho will be right

Arp does have mains and rod studs for m20, check Ireland engineering that's where I got mine
