Part no. of a GZE piston

[oldcorollas]

pistons went for 20500yen plus costs.. sayy 22000yen = $260

dont buy them stew, you want higher comp than that.

and 30psi ring james at castlehill toyota {spareparts} and tell him you want a set of std bore ae101 gze pistons! wont be a problem! lol your about 4 months to late, i gave a mate a new set of std i had sitting here for years.

cheers for that m8! +rep

spewin about the pistons

higher comp??? why???
8.9 is high enough, and thes ehave squirter coutouts anyway....surely higher comp would start to limit possible boost?

edit: if you want to go to more than 20psi boost, or higher rpm, you would be thinking of diferent pistons anway... i'm not thinking that outlandish no dyno queen for me

Im glad you asked the question because i was thinking the same

i have said it time and time again but those pistons are the sh1t !

The price you can get them for and the quality ( expect nothing else from toyota) they are + the ceramic coating is second to none in factory issued engines.

I feel they are better than some aftermarket jobs !

Like the before mentioned : they only down side ( small ) is their weight !


Ahhhhh if only i could put the vid of my car letting go on the dyno on here you would realise just how much of a beating they can take

is the part number 13013-16210 for an ae92 4agze (8.9:1) with a standard bore with no rings?

I am chasing some for my 20v

[DX20VT]

The number on top of the pistons 1, 2, or 3,
are in relation to the bore size.

they are all bored bthe same from factory, but you always get a small tolerance difference between cylinders.

Only applies to standard bore size of course and when you go o/s you make the block suit the pistons not the pistons suit the block.

The differences are in thousandsth of a mm, and most are size 2, but you get the odd one that is a 1 or a 3.

If you look at a block with the head off you will see the 4 number stamped into the head gasket surface somewhere, same kinda deal as the main bearings sizes are stamped in the sump surface.

I run the 8.9 GZE one's in my 20V too, no problems yet up to 300hp.

[Sam_Q]

would this still be valid for a 20v block though?

Yes the numbers relate to sizes, like at a guess, 1 is 80.95, 2 is 81.00mm and 3 is 81.05,
and the same system is used on the 20V so it applies there too.

I used all size 2 of the 8.9:1 GZE on my 20V block as they were all marked 2 also.
Was lucky because the 4 s/h pistons I had were all marked 2 too.

[30psi 4agte]

I would say so....... but if it were my engine id just measure up the bores after a light hone.
If they are within the factory spec order pistons to suit.

Id prob be inclined to order all pistons of the same no. ....like all no,2 pistons in my engine. but thats just me i guess.


Edit : bah beaten

[Sam_Q]

I will do just that thanks. But what is the tollerence for each piston? is DX20VT's guess right?
