piston help Options

[trd94]

ok i have read that the 4age head gasket fits a 7afe so i would like to know if i use a set of 4agze pistons with a 2mm head gasket will i be ok for 10-12psi of boost or will the gze pistons raise the compression to much even with the 2mm steel gasket just need some input befor i buy parts i dont need thanks guys

lagos you do realize stock compression is like 9.5 on a 7afe i think
or its in the 9s...all that is required stock is 83 octane...
an Emanage Ultimate with 94 octane @ a 10:1 CR should be obtainable with minor implications.
and actually those hondaz are on pump gas
**** add some H2o injection for knock control

@ .9bar doggy was making 206whp on an unopened motor
increasing the CR and tuned @ the same .9 bar it could probably see in the 220s
and some water injection maybe 230s

do we really know? no
is a higher then stock compression build possible? yes
will it take research and some trial & error? yes
does this mean we shouldn't try? no

I'll even donate the motor for 40$ to do it with

doggy DID NOT make 206whp
206HP.
10:1 compression ratio in a 7a, without a standalone, = boom.
end of discussion, dan.

ok wow hp whp whatever the orig. poster made 207hp
i'm pretty sure in my post it says "properly tuned" go back and read my posts when we first started talking about high compression
or is reading comprehension not part of 6gc criteria?
where did i say to try that compression ratio with an safc? yea i didn't
all my post clearly stated properly tuned...to yall ricers that should translate into higher level of engine management, dyno time and a tuner

also to note..he wouldn't be the 1st person to runa 10.X:1 compression ratio on 7afe in a 6gc using 4agze pistons...

-New head with:3 angle valve job,P&P,CC compared and polished,squish job,valve guides reprofiled and CR raised to 11.06
-Arias 4AGZE pistons

tuned using a greddy emanage...
is it a boosted motor? no
is it a HIGHER then discussed CR? yes
is the motor working correctly? yes
with lower cr and a lil boost could it work if properly tuned? yes

and like i said i'm even willing to donate a full motor so he can do it...along with the research and data that i know about boosting and building the 7afe cause if you think i've posted everything i know about it your tripping yourself...
what have you offered? besides the restated?

end discussion,
