yes they do but you have to get the 4ag pistons that have 20mm wrist pins i had 4agze pistons in my 7agte but swaped them out for ARIES pistons fully forged

stickers mate, the more stickers the more hp...

and 'BEAMS' sticker on engine is the most powerful (own experience )

When taking the head off the 7afe engine block is there gaskets, specialized tools needed or anything else I might regret having when I change the pistons? (I really need a Celica manual)

If you add a "TOYOTA" emblem on the valve cover, it will provide you even more.

Very nice clean engine BTW.

haha, i love your redtop "beams".

"no you cannot put the 4agze pistons in to a 7afe
block they are not right and the 7afe block will granade"
Do i have to get the 4age head for the swap>???

The 4AG pistons with 20mm wrists do fit... but only with modification to the 7AFE rods (full float versus press fit pins). 4AGZE pistons will raise compression mated to the 7AFE head... but will lower compression on the 4AG (in a 7AG hybrid build) head. You won't be able to do anything to the pistons and rods without a press and the proper tools (press plates, etc for the pistons), otherwise you might as well kiss the pistons and rods goodbye. If you've NEVER built an engine before... this is NOT a good place to start... switching parts and doing custom work is not for beginners.

I wouldn't go messing with the internals in the ST unless you've built engines before in the past, and planning on doing more than just swapping pistons, which is a big job to the novice.

If you want the ST to have more power, turbo it. No amount of N/A modification is going to net you any serious powers, it's difficult to build on a platform that doesn't even see 100hp to the wheels.

I believe Nik is the only member here who can honestly say he's done as much as he possibly can to the motor he started with.

thnx for the advice, I think for now i will save up money for the 7afte parts. In the mean time i will buy a 4agze to learn from, eventually swaping that or making a hybrid of the two much later down the line.

ps

One of my best friends has a N/A board out Datsun 1973 510, No Smog Checks ! We've rebuilt two engines so far and we also have a 3ed on the way, so Im not a complete noob.

pps

The 510 actually just got coilover eibach springs which we g6's can pic up too for $400!
