Hi, first time mitsubishi owner. i have a 2012 lancer es and im going to be boosting it soon, and seeing as how the na 4b11 uses one time torque head bolts i wanted to change them out with some aftermarket head bolts, but so far i cant find any. so i was wonderring if i can use the evox arp head bolts or if theres a company that makes any. would i also need to change the head gasket. Thanks

 

I'm using ARP head studs. Of course head gasket have to be changed.

For ARP studs you will need to fabricate special tool to tighten the 2 nuts on the timing chain side.

Look my turbo thread on 9glancers.com for more info.
