4AGE and 4AGZE bottom end differences?
|

OK, I'm up on all the generations of these engines (Phil Bradshaw's page)
I've read that there is no difference in crank, rods or blocks between NA and supercharged versions of a given year (old thread)
Can anyone with direct experience confirm this?
The question I am getting to is if I build a spare engine, does it matter if I start with a 100kw, silvertop or late ZE bottom end? Or are they all essentially identical (bar pistons of course)?
Thanks
Hen

they are both right......
ALL 42mm crank 4age/4agzes had the same cams, that goes for aw11 4agze. late aw11 4age, ae92tvis, non tvis, ze map, ze afm and ae101 ze.
the 40mmcranks type, ae82 early aw11 had different cams
lets make this simple......
all parts that are differnt on the 4agze compared to the 4age:
pistons.
rings
camcovers
thats it. blocks, cranks, rods, heads, cams are all THE SAME
|
I would say that what is here by Mr. Revhead "should " be pretty reliable info as he works at toyota and checks part #'s and the like.
I have had him check stuff for me like the ge and ze oil pumps are in fact the same...
I am very interested however to know definately from someone with direct experience also..

I needed a new crank for an AE101 4AGZE, picked up a complete 100Kw engine, for $200.00. The crank was a perfect fit, all the journals were correct diameter, for the GZE rods.
The block is useless, unless you have someone capaple of fitting the oil squirters.

you might need to register to view
but the jist is that yes, 4ag rods are same within years, so late 4agzes have the same rods as 20v. shock, gasp, disbelief
but it makes sense, as toyota would forge the same STRONG/BIG rod for all the 4age and 4agze motors.
so i'd say the sweet spot for 4ag production, is 87 to 92???

One particular rumour I was trying to clear also was that ZE cranks are steel whereas GE cranks are cast iron.
Anyone able to shoot that down?

So fitting GZE pistons to a silver top would give you a 20v GZE?
If so , why do people talk about fucking around fitting a 20v head to a GZE bottom end?

Hey,
Would the Crank in a 86kw 4age be the same as one in a 100kw?
Sorry if it's a stupid question

the 86kw (bluetop 3 rib) will have the same mains as a later 4age, but the bigends are smaller (40mm vs 42mm as mentioned above). so no, its not the same crank.

From what i have gathered is that 4agze's are the same as the smallport 4age. Which means it gets all th goodies 4agze's get. The only thing that ever changes is the pistons for compression reasons and boost applications. I know cos im building a 4age smallport for turbo and every part i have bought comes from the 4agze, all bolts, Oil pump, Bearings and pistons i have ordered and is ment to be used in the 4agze but im putting in the 4age 100kw and there you have it a turbo late model 4agze.
