4age pistons (ex groupA/rally engines)

[ae70_4age]

Hey guys,
i have some 4age 16v engines and parts from old rally cars.

I have a few pistons here, just wondering if some one can identify them?





Theyre mahle pistons,81.15mm diameter. look to be forged. 18mm pin (to suit a floating pin/rod)


Theyre mahle pistons also, 81.06mm diameter. forged aswell i think, 18mm pin same as above,
Came in a TRD piston set box, labeled group A rally pistons.

The block i got with this was a brand new ae86 3 rib block, got the box from japan it came in!
Has a good condition Toyota Group A 40mm crank, is not a TRD item.



Next motor, has a TOYOTA R DOT BLOCK. 7rib, no oil squirters. Bigport head with a mint port job, 288/9mm cams, ran on carbs etc.
Crank and rods are early bluetop, but the rods have been machined to take a 20mm press fit pin,
The pistons are toyota pistons, oversized 0.5mm. Theyre flat top and look like they mightve had a teflon coating?

Apparently running around 13:1 compression.

Has anyone got any info on these? Also any info about the group a motors would be good.

Thanks
Daniel

I think i got the layout ok.

Daniel, you haven't got much response, so I hope you don't mind me asking a related question. I also have a TOYOTA R DOT BLOCK and I was wondering what it signified. Do you know? Anyone? I believe my block is from an JDM RWD 4AGE big port.

Hey, nah its allgood man. What does yours say where the block numbers usually are? (like 4a, 4082345 or something like that)
Im not too sure, i thought theyre blocks that werent factory fitted to vehicles, but were purchased from toyota as a reinforced block? being 7 rib. Im really not too sure..

Looks just like an engine number to me: 1364123

Ahh ok, my r dot block has no numbers on it, It just says 4A, and thats it.
