well i spun a bearing in my gsr bottom end and my buddy is giving me his complete b16a3 to run in my car for the mean time with my gsr head... now here is what i am curious about, a 1 layer head gasket will take me up to 11.1 compression... and oem gasket will take me to 10.5... i was wondering which would make more power.. 11.0 compression at 8 pounds of boost or 10.5 compression at 10 pounds of boost... or the 2 layer which will yeild about 10.7 at 10 pounds of boost.. now keep in mind this is a temp setup til i get my gsr built i would like to be around the hp of my previous setup... i want around 350whp.. i have typical mustang owner i need to shut up lol

anyone have any suggestions.. im trying to get it re assembled and put in the car tom or sunday...

11:1 on 10 psi would be faster

but would it hold.....

the lower compression, the easier it is to tune...keep that in mind. and if it aint tuned right at 11:1 comp she aint gonna take the boost all that well

im the friend thats lettin him borow the motor i dont care if it blows but can the stock head bolts hold the 11:1 comp and 10 pounds of boost with out blowing the head gasket?

Well, if you are thinking of putting a 1 layer HG on the car and then re using the stock bolts, you are already on the wrong track.

I for one wouldn't even reuse the stock bolts on a nitrous motor with a small shot, much less an 11:1 motor that will see boost all the time. When you bump the compression, the room for error get's smaller and from the sounds of it, you guys don't need it any smaller. If he is giving you the complete A3, just run it like that, the B16 head flows better than the GSR head anyway, no need to try and add more compression and give you an even better chance of making it puke everywhere. Just run it like it is. If you insist on putting on a GSR head for some reason, then spend the cash to get some head studs and find a good tuner.

well we ended up using a 2 layer... which is 10.7:1... he is using his b16 head on his b20 so he just loaned me the bottom end

run a 3 layer and run more boost. expletive taking apart a stock head gasket. i know people do it all the time, but make up compression with 1 more pound of boost

i pushed 10 pounds on it tonight with no problem yet... any ideas on how high i could go? 12 maybe.. there was a guy at mir a few weeks ago who pushed 14psi on his stock type r.. he was running 12 at the track

after 14.5ish the stock map will spaz. its all in tuning. stock motors take 18+ psi all the time, if tuned correctly

yeah, i need a 3bar badly.. im trying to get it retuned this week and see what i can do.. im impressed by the b16 so far, i want to see what kind of numbers its going to put down... my afr gauge never went higher then 11.2... my hondata is still tuned for the gsr on 8psi

yea but im also still running stock head studs... i was hoping to push 12 psi with no issues
