I have blown four OEM gaskets. once after a year on 15 lbs on a T25/28 setup, twice at 15lbs on a gt30r and once at 20 lbs on a gt30r with a perfectly flat block and head. unless you can keep the temps well below normal operating temperature, that thing just gets holes blown right through it into the water vanes. I am not so much a fan of copper head gaskets on street cars either, but in our case this is our only option. Cometic wants a minimum of 50 gaskets before it will design and produce one, i have had friends higher in the industry and myself contact them more than once. Ajusa no longer makes one, and wont start reproducing the MLS, ive tried, and Felpro basically said F you to me when i asked them about making an MLS even though they already make a standard OEM replacement and have all of the blueprints to design one. Typically the graphite head gaskets on all Nissans are the weak link, most notably on the KA24 who has the same problems i, and im sure many others have encountered. Yes, the copper head gaskets are difficult to get under control initially, but until someone decides we are actually worth the performance industry we cant really do too much else. Plus, the copper gaskets are good to some crazy like 2000hp under like 250 degrees or so. Nothing beats that, lol
