Default Studs

Well I've been looking around like a mad man for head studs for my 2.2t. I called ARP and they said that they would make them for a $10 grand tooling fee. I really don't want to use factory hardware, studs are much better for high performance engines. Thanks in advance...Gerry

Shouldn't all the EJ engines use the same head studs? Considering the size of the market, you'd think it would be worth it for them to make a kit. Rod bolts would be nice, too.

No Subaru's use studs. They use bolts

Depending on the length and thread, I'm sure they cross-reference as something. If you do find something. please let me know. $10,000 for a tooling fee sounds absolutly redicuolous!

If you find a crossreference that is a bit longer, you can always cut them down. I would thing that many Imports use the same threads.

Yeah that's a good idea about crossrefrencing but I really don't want to go out and buy 5 sets of honda studs. Australia and the UK are a bunch of Horsepower freaks, someone has to have something available over there. Maybe i'll call Tony Rigolis shop during the week....

That's true. However, make sure that the Euro/Aus EJ20's use the same studs as the EJ25 would

Heh.

Anyway, upgrading to ARP studs can be labor intensive, but is worthwhile.

Just making sure... you are aware that the bolt heads for the EJ25 heads are two different sizes, right? Seems they had the outside ones made with less shoulder so they fit in the head and make it to the seat - the center bolts won't make it all the way to the seat in the outside bolt holes.

BTW, I'm sure for a price you could have custom bolts made up and hardened that would work just as well.
