ARP rod bolts

[staggy_gsi]

right everyone keeps going on about these but what advantage do they actually give you? im currently rebuilding my E16SE and am about to re-fit the pistons, is it worth me buying a set, and if so how much are they??

cheers, adam :thumb:

well it stops the rods divorcing the con rod at a high RPM completely destroying the engine. Id say they were a useful mod lol

Prices vary, shop around!

They stop a conrod making an appearence through your block, as they are harder/stronger than normal rod bolts, so dont stress/stretch.

There about ?50.

Rally Design sell them.

nice one bud. i might sound stupid here but whats the countersinking all about though?? how and why do you do it?

[Adam]

You have to do it.

The caps have to have the hole countersunk slightly, as the ARP bolts have a small radius on the underneath of the head.
If you dont countersink the hole all the stress on the rod/cap goes into the radius on the bolt, instead of the whole bolt itself.
