Which ARP Studs

[PDX92TSiAWD]

I have found a lot of conflicting information on which ARP studs to use for my cylinder head. I have a 92.5 Talon TSi with the 7 bolt 4G63. Some vendors, including Slowboy Racing, say to use the 11mm studs for any 7 bolt engine. However, other vendors and even ARP’s application chart says I should use the 12mm studs for all 1g cars.

Can anyone that has replaced the head studs in their 7 bolt 1G tell me what studs you put in?

Thanks,

Ryan

I was under the impression that 7 bolts use the 11mm and 6 bolts use the 12mm.

Lunchbox is right. Say if you are doing a 6 bolt swap with a 2g head you need to drill out the head bolt hole because the 6 bolt head bolts are 1mm bigger.

I want to put ARP head studs as i change my headgasket, but no vendor seems to offer them for a 1.8......will the 2.0 head studs work with my 1.8 and if so what size
