SR20 ARP head stud part number???

[silviadad]

So what is the correct part number for ARP heads studs???

ARP catalog shows 202-4201

I have seen these part numbers listed also on other sites for the SR20

204-4204
202-4303
102-4701

So what gives? I would assume ARP knows what stud is correct but why so many different listings?

Thanks.

I remember when I was getting the arps they had an older model stud that had problems threading completely, one might be for the blacktops? - someone who knows will post but make sure you get the right ones!

This is for an S14 black top engine.

The other thing that has me confused is some are listed as 11mm and some are listed as 12mm. The shop where our block is said the OEM bolts we sent with the block are 11mm.

alternatively Head Studs - Mazworx (http://www.mazworx.com/products/cylinder-head/nissan/sr20det/head-studs/)

you can pick up mazworx head studs and eliminate the guess work

The first ones are VW 1,8L Head studs, they work fine i still sell them to this day,

the second ones are for the GTiR they are bigger thread, wouldn't use those

the last ones are the ones you idealy want to use since they are listed for SR20DET RWD, they are also the most expensive ones.

I'd use the VW ones if staying under 400hp if going over 400hp or allot of boost i'd use the third part number.

Thanks for the help.

ARP 102-4701 are the correct ones.
