bmarchuk Posted February 19, 2011 Share Posted February 19, 2011 Can't seem to find a supplier for this I'm wondering what the best option is for a 1mm head gasket on an engine with a f54 / p90 combo and where I can find it. I'm specifically looking for a 1mm gasket or a layered gasket possibly? Also curious as to what the difference in a gasket for a p79 would be, can one be used? This is a non turbo application Thanks for any help in advance! Quote Link to comment Share on other sites More sharing options...

A p79 and p90 is the same gasket Quote Link to comment Share on other sites More sharing options...

bmarchuk Posted February 24, 2011 Author Share Posted February 24, 2011 How do you know either of those are 1mm gaskets? I can't find any information on them other than they are an oe fit. The oem gasket is not 1mm Quote Link to comment Share on other sites More sharing options...
Pyro Posted February 24, 2011 Share Posted February 24, 2011 I got a garage full of new and used felpro head gaskets for Z's and they are 1mm (0.040") thick. I never used a nissan head gasket, but hear they are 1.25mm. 1mm or 1.25mm is not a big difference, I can't image it would make any measurable difference in performance.

bmarchuk Posted February 25, 2011 Author Share Posted February 25, 2011 Actually it's been heavily researched and a p79/90 with flat tops that .010 matters you need to get the piston as close to the head as possible to squish the air more into the head chamber to reduce detonation. I've done the research, it make sense. I think it matters and when building a very specific engine it is a huge determining factor for power when considering compression and detonation thresholds. But ive also heard bad news about the Felpro gaskets. I'm really just wondering if the ones msa sells fit a p90 or what because my p79 and 90 have the same oil passages and it fits for a f54/79 combo it should for a p90 as well than Quote Link to comment Share on other sites More sharing options...
Pyro Posted February 25, 2011 Share Posted February 25, 2011 Yes, I'm aware of quenching. But, for a street L28 engine with flat tops and a P79 or P90 head it will not make any difference you will ever notice. what I'm saying is you are over engineering your engine. Get a felpro and go. The L28 flat top build with a N42/N47 head makes 10:1 cr and has very little quenching due to the poor chamber design and it works well. I have never had any issues with felpro's. Make sure the surfaces are clean and flat and they work great. even with boost. Quote Link to comment Share on other sites More sharing options...
BluDestiny Posted February 28, 2011 Share Posted February 28, 2011 I'm running a felpro with my flattop/e88 combo and haven't had a problem. Seriously pyro is right if this isn't some crazy race engine, in which case you would get a hks or kamieari metal head gasket(motorsport auto has the kameari one I think). On a stock engine you won't be able to tell the difference between a felpro or a mhg unless something else is engineered improperly and you overheat or detonate. Measure once and all that... Just searched and they have the Nismo .6mm one if you're crazy. Quote Link to comment Share on other sites More sharing options...
blue72 Posted February 28, 2011 Share Posted February 28, 2011 I just took a brand new Fel-Pro out of the packaging last week and uncompressed it measured 1.13mm thick. BRAPP has said that he's measured many compressed Fel-Pro head gaskets at 1.12 - 1.14mm. Quote Link to comment Share on other sites More sharing options...
280zbeeT Posted March 5, 2011 Share Posted March 5, 2011 (edited) n42 .30 bored block with p90 head with a NA cam with flat top pistons running a standard felpro head gasket, what is the compression ratio? its a turbo engine Im trying to get tuned in these next couple days..
