4agze pistons ina 7afe???, will they fit? Options

[playr158]

well then i better make sure i have an aluminum radiator with good coolant and good fans

i'm still looking for a new rad i might do a honda race half radiator thats like 5 inch deep not sure yet

[playr158]

i'm not a big fan of half rads i'd rather run a skinnier full rad....

i would like a full length one but it might come down to room if i have the room i'll go full if i dont half will do it

[playr158]

i would say that the invader front we're both using is large enough to modify and runa full radiator mounted inside of it like infront of the heater core but behind the crash bar? maybe its possible
and makes more room

OK I read through the post and we have seemed to have found a good custom piston to have stronger internals but what about forged rods where can we get those?

[playr158]

already been convered

you have two options

low boosting---stock rods shot peen'd
high boosting (10psi plus)
CUSTOM

[94ST2]

How much would the pistons and rods run?

[right][snapback]281186[/snapback][/right]

quite a bit... on average... around 600 bucks for custom pistons and 600 for rods...

[94ST2]

Yeah I was figuring around that much thanks.

yeah i looked at that i just have to get some measurements and see what rad will fit plus i need the outlet and inlet on the passanger side or atleast the top one

oh you would have to use the 4age rad then huh?

well even if its not on the right side
you can go down to advancedauto or sumthing and pick up some extra hose thats just a bit longer and extend it.....that shouldn't effect anything...

[nik]

i just want it to look clean and not have 4' of hose in there

[playr158]

well you shouldnt see most of the hose since it will be inside the bumper

just the 1' that goes from the head/wp/block or what not
to the bumper enterance you keep the rest inside the bumper so you can't see it

bro's,

so may i assume that if i wanna build a high comp NA engine on 7aGE, which piston should i go for?

[playr158]

7age? your doing a head swap or a 7afe?

if your building a 7age then you HAVE to use 4age high compression pistons

if your using a 7afe....then normal 4age regular compression pistons will do just fine...you'll end up around 11:1cr

[normality78]

Tks dude.

Well engine has been open apart to check on condition now. most likely will go for a head swap. my mech was saying why not 20V but i don't really like the idea of having serious power comes only at 5500rpm later..

As for FE head, i felt its very "lazy" in revving

[playr158]

cause its an econobox head

K, time to write it again.

As i know for now im the only one who TRYED TO PUT GZE pistons in the 7A.

First: EVERYTHING FITS LIKE IT SHOULD BE.

!!!!!!BUT!!!!!!

I used GZE (or GE)20mm wrist pin pistons. The wrist pin of the GZE is the same diameter as the 7A pins. BUT wrist pins of the GZE (or GE) pistons are FULL FLOATING, 7A pins are PRESS FITED. Difference is what 4AGZE rods have coper/bronze insert in the top of the rod, AND wrist pins float in it, and there is the oiling chanel in the rods for oiling the pins. 7A rods DO NOT have pin insert, DO not HAVE oiling cuz pin is pressure fitted and DOESNT move in the rod pistons move on the pin.

Then puting GZE (or GE) pistons MIND one thing: GZE pistons pins are full floating, so the restriction of the pin floting is in the piston. Then you press fit the GZE pins in the 7A rods - you get what the pistons dont have enouth of movment then they are cold (basicly pistons are stuck on the rods and kinda hard to move by hand if they are cold, but its enouth to heat them up a bit and they start to move...) This was the main reason what i aint used these pistons in my project (cuz i wanted to turbo my engine faster and aint had time to solve all this )

BUT, i asume using your STOCK 7A Pins with along GZE pistons - everything should and i say SHOULD be good... i dont know yet, i will try later about this...

Good luck guys.

We already know this, what about the compression ratio? That's the question that hasn't been confirmed.
