This has already mangled my melon

Is this why perhaps my other 4age seemed a hell of a lot more responsive because it had higher comp pistons in it?

Am I really going to be able to make 150+ hp with my mods with these piddly pistons in comparison to high comp?

@ditn: it'll be interesting to see if it also has the extra "meat"

Bean Bandit Wrote:I stand corrected, the dish is the same as other 9.4:1 CR pistons... first time I see one of those with a 20mm pin.

I told you they existed Tongue
And actually all the first generation of AE92 in Japan (and France, at least) had this pistons.

I will email you the japanese table and maybe translate it for everyone else here Wink

But this picture already give you all the generations:

PS: My AE86, who was one of the latest produced AE86 (10/1987)
had one of this "red and black top" (7rib and red "16 valve" on the cover)

I can't tell for the internal parts, I never opened it, but one of my friends (who worked at toyota) told me that Toyota made "hybrid" in 1987 (7rib but 40mm crank) So there is a good chance that mine is one of this

Mine should be one as well since its not correct with any of the above pictures.
colors are from picture 2
its a september 1986 belgium TVIS 7rib 4AGE ae86
It even says 91 kw on my papers :o
So hybrid would be started even in 1986.

i can make pictures of pistons tomorrow,will need to do some work to show the crankshaft.

my AE86 feels old now - although it's one of the first koukis it's from May 1985. On a positive side it didn't come with a CAT.
