Hi Guys,

I've already installed the ARPs using 1/1 method, torqued at 85ft-lb..

I had not planned to install a new head gasket..

However, my tuner advised I install a Cometic or HKS head gasket before he performs the tune, since he is going to reach high boosts levels with the new turbo kit (aiming 28psi)

Please I need your advices on the following:

1) Will the ARP's studs work again normally when I remove and later install them back after the HG install itself?

2) Will i need to change the timing belt to a new one? My car has 17,000miles (25,000kms)

Thank you for your responses..

1. Yes, this is the reason for studs. They can be used over and over, to a point. Remove just the nut/washer, not the stud/

2. If you have the means, put an aftermarket/stronger belt with any replaceable parts (Tensioner ect) if you deem doable.

If you don't want to risk gouging the hell out of the bottom of your head and make removal about a million times easier I would remove the studs as well. Just replace them after you pop the head back on. Removing a head is awckward enough in the car, but having to pull it straight up another 8 inches or so really sucks.

Oh yeah, and I would leave the timing belt and associated hardware alone.

Why? Its a good idea to replace the timing belt! Especially on a modified high horsepower engine.

Grenade says i can use the studs again, they're meant to be used back on..

Coolnick says i got to replace the studs?

Me, I'm lost!

depends if they are stretched or not.^^^ Since they were torqued beyond the recommended settiong from ARP, they are most likely stretched. Whats is wrong with your stock Mitsu headgasket??? Last I checked, AMS had one pushing 44lbs of boost...

the recommended torque value using their lube is 85lb-ft, i dont think they're overstreched!

Yeah, the guy said the car will take the boost with the stock HG, but for how long.. that's the issue!

Your tuner sounds like he is trying to sell you an expensive job for no reason. Unless your head gasket is blown, there is no reason to replace it. It is an awesome gasket capable of holding huge amounts of boost and HP. This makes zero sense!

P.S. 28 PSI is not high boost considering many of the aftermarket turbo's spin up to over 35 PSI.

I agree replace it when you need to don't make more work for yourself

if it isn't leaking there is no reason to rip it apart

a lot of people make huge power with the oem gasket. i wouldnt chnage it if you dont need too.

a cometic head gasket requires a very smooth surface to seal perfectly, since your not pulling the motor, i wouldnt recomend a cometic.

i am sure you'll hear people just installing a cometic without issue while not getting everything perfect too.

i thought you needed to replace head studs when ever u removed them

If you do change the head gasket and use the same studs, be sure to lube them with the ARP lube on reinstallation, and follow their torque sequence (if I recall, it is something like 4-5 torque, untorques with the lube to debur and get a smooth contact for the final torque pass - keeping them lubed).
Just visit their website for instructions.
