2.3 liter built motor, ported and polished head, stock turbo for now, and planing on 35r kit. will run alky occasionally. I am curious if the stock head gasket would hold the high amounts of boost well. If not I am curious what recommendations you guys may have. Any input is valuable and appreciated.

 

bump anyone?

 

As long as you have ARP head studs your stock gasket was properly seated/sealed you should be fine for 20-30+lbs of boost.

 

I believe AMS runs the stock head gasket on there cars.

 

With pump fuel, you won't be able to run more than 22-23psi with a proper tune, so it's a non-issue.

With a shot of methanol, you'll be able to run more boost, but this is still a non-issue.

The factory gasket isn't a composition type, and isn't prone to failure. The biggest threat to the integrity of any head gasket (aside from poor tuning) is improper surface finish and/or improper head fastener torque.

 

boost is not the only thing that effects that, timing does as well...

 

thanks for saving me some money guys!
