Looking for some answers/experience on head lift. I've tried searching but I get limited info, and mostly stuff on D series.

Is it a pressure Dependant problem or power? aka will a small turbo that makes more boost to reach the same power as a bigger one at less boost have symptoms before its counterpart?

Does blow by have anything to do with it?

Has anyone had head lift on their stock B series?

 

did you google

 

just buy arp head studs and call it a day , cheap insurance

 

cylinder pressure. power not boost.
you'll likely to have a leak say at 250WHP on .5bar on big turbo
than 200whp on 1bar on small turbo.

 

And remember that cylinder pressures double, triple, or even more every time you have a detonation situation. This is what causes the issues generally.

 

oversized studs and fire ring the block

 

oversized studs ar completely overrated and more trouble than they are worth. regular arps or golden eagles or aebs studs are being used in 900+whp honda applications.

head lift is from to much power for the stock bolts and detonation. when you have detonation its drasticallyt increases cylinder pressure far beyond what power production is doing causing headlift and cracked sleeves

 

Specifically speaking, cylinder pressure, which can be caused by power or detonation. You can get away with stock headbolts if you have a really good tuner, someone who will dial back your MBT. Honda headbolts just weren't made for boosting, they stretch and loose strength over time. ARP's will take care of any issue you might have.

 

im having the same problem on a built d-series with arp head studs it has vitara pistons with t3 super 60 and it will make alot of pressure in the cooling system when you get on it still have not figured it out

 

probably a bad headgasket or warped head/block something of that nature. theres no way you are getting head lift with arp studs and a tiny turbo like the t3 super 60

 

are you tuned? post a map?

 

Caused by cylinder pressure...basically the volume of air inside is compressed to a point which exerts more force on the head than the bolts can hold without stretching (noticeably since they technically stretch all the time)...so they stretch too far and you blow a headgasket. This has nothing to do with boost per se. A quick fix would be a set of ARP headstuds...problem solved
