high boost, need new headgasket?

87supraturbo · 08-26-2005, 01:12 AM

i just bought a 87 7M-GTE and as far as i know the headgasket is fine it wasnt driven very hard by the previous owner, but i plan to drive it like i stole it and i want to put on some BPU's to increase boost, should i put in a metal headgasket just to be sure i wont blow it, or should i be ok if i just re-torque the bolts?

thanks

do it right and get a greddy bead type head gasket,if your head gasket is good now,now would be a good time to replace the old gasket without consiquence because no damage has been done yet.if you are poor just make sure they are torqued to 72 ft lbs.

How many miles on it.. If its stock gasket, its not if, but when its gonna blow. Todays newer version of toyo dealers stock gasket is much better than the ones made in 89.. whowever. when it blows, youll know it. should not hurt anything unless you keep driving it and overheat it badly.. then do the metal gasket. but im a dont fix it till its broke kind of guy on most stuff thats how id roll it....besides. anything over 15+psi i think a metal gasket is almost a must???

my 2 cent
