7afe, 4agze pistons ect.., new quick question Options

[playr158]

aite running 7afe
with 4agze pistons 81mm stock bore
and a .5mm headgasket
port and polished head
and 93 octane gas i should be fine
and not need any fuel upgrades right?
altough compression went up?

anyone.....kwanza?

i would get a fpr thats adjustable to be on the safe side and a wideband o2 to make sure your not going to lean out with the higher comp

What nik said. The exact compression levels will be mostly unknow till it's done, and will depend on which 4AGZ pistons you use... but I would imagine the stock fuel system should do OK with proper tuning.

i'm goin to use just stock 81mm 4agze pistons
but how would i "tune" with a stock ecu?

[nik]

you need a piggy back system check ebay my greddy porfec e-01 and emange are for sale pretty cheap

[playr158]

thats the thing i can't afford to get a piggy back right now....and i really dont' wanna have to go past the stock ecu for now until i go turbo
i wanna run the ported and polished head with the pistons as an N/A setup to get a lil more kick to the ride without making major mods
cause my motor needs to have the valves redone and pistons' replaced b4 i drive to seattle in july then when i come back the turbo setup starts

Which 4agz? 8:1 or 8.9:1

Don't you think the compression would be supremely high with the .5mm gasket and GZE pistons... especially the 8.9:1 compression ones which I am sure you have...

Do you have the parts for this thing yet?
