Hey guys i have a turbo D16y8 on 15psi, and the thing is i have done everything right, as far as the tune and build. but i have been throguh 2 Head gaskets already, What brand of gasket do you guys recomend for boosted aplications?

 

Do you have arp headstuds? OEM is what most people recommend.

 

yeah i have the head studs and everyhting. the engine builder picked the last gasket , and IDK what brand it was. but OEM will do?

 

OEM D16Y8 head gasket is the best D-series head gasket. Well, maybe with the exception of Cometic... but i've heard those aren't good for boost. The thing about OEM D16Y8 is that it's a metal gasket and is therefore more durable.

Make sure the head studs are being torqued down in the proper steps and sequence. Also, make sure the head and block have flat mating surfaces and are clean.

 

Metal headgaskets are usually best. Cometic gaskets are okay but not for a D16Y8. Remember that Honda has a great engineering and racing heritage and for the most part their parts are the best for the application.

So, whatever gasket you choose : clean the mating surface really well, apply the gasket in the correct orientation, torque the bolts properly & replace them if they are stretched outside of factory specs, and apply a sealing compound around the edge of the head to assure good mating.

Also, if you are blowing headgaskets with some regularity and you have tried several different gasket types it may be a sign that your block or head is warped. When either is warped it is possible for coolant and gases to escape where the mating surface isn't flush. This escaping fluid or gases causes a hot spot and the gasket blows.

Consider that. Boost by itself doesn't cause blown head gaskets...usually...typically it is the fact that the surfaces are not mated together completely which causes a weak spot. That weak spot turns into a blow-out.
