Is there a difference between these please ?
Have read contradictory info & seen contradictory pics
Do both have an 8 bolt flywheel to crankshaft fastening
4A-GE & 4A-GZE Crankshaft & Flywheel

Re: 4A-GE & 4A-GZE Crankshaft & Flywheel
the crank from a 7-rib 4AGE is the same as that used on the GZE (With the exception of the pistons and the cam covers the entire long block is the same)
3 rib 4A-GEs have a different crank with smaller big ends.
Flywheel fastening is the same on all 16v GE/GZE although the flywheels are different (this is down to the different gearboxes used with the various engines in factory cars, complete clutch and flywheel assemblies can be freely swapped between different variants to suit the application/box)

The flywheel on a mk1a is 200, mk1b 212 but on a 4agze its 224mm
You cannot use the n/a clutch on this flywheel
But you can refit the 212 diameter flywheel on the crank and run standard clutch and C52 box

It's only the *very* early mk1as that have the 200mm flywheel, most cars have the 212mm one.
Re: 4A-GE & 4A-GZE Crankshaft & Flywheel
I have a Toda Racing flywheel & clutch here
Have uneasy feeling that they are not correct items for my Mk1b
Will take some measurements & post here later
EDIT :
the friction surfaces of the centreplate & pressure plate appear to be 218 mill dia

Re: 4A-GE & 4A-GZE Crankshaft & Flywheel
There are 21 splines on the clutch as well.
What was the clutch and flywheel listed for when you bought it Peter?

It was listed for 4AG engine Alex
There are 21 spline slots in the hub of the centreplate
The pressureplate part number is 22300-4AG-200
The centreplate is 22200-4AG-21N
Flywheel is 22100-4AG-200

Re: 4A-GE & 4A-GZE Crankshaft & Flywheel
Did you buy these new?
The fidanza flywheel appears to be lighter than that.
Admittedly when I was looking for a lightened flywheel I was struggling to find a 212mm diameter one. All they seemed to throw up was a 200mm flywheel.
I'm thinking that the diameter is in the part number I.E. 22100-4AG-200
So I believe you have the 200 mm flywheel
Its not a problem, but didn't you look into the diameter before you bought it?

They're brand new in original boxes & sealed in original plastic bags Alex
It's the 200 part of the part number that I'm uneasy about
The diameter of the friction surfaces is 218 not 200 though

Re: 4A-GE & 4A-GZE Crankshaft & Flywheel
I can't remember what mine was, but I knew I wasn't going to have issues as I bought the correct size
Re: 4A-GE & 4A-GZE Crankshaft & Flywheel
Surely it doesn't matter in your case Peter, as long as the flywheel and friction plate mate up and they physically fit in the bell-housing? Just the spline count is the important bit.
Interesting tidbit on the standard flywheels, the 200mm version is heavier than the 212mm.

Re: 4A-GE & 4A-GZE Crankshaft & Flywheel
All you have to do is put the clutch pressure plate over the flywheel and make sure the dowels line up and your golden.

I would like to have the strongest possible as well as lightest possible flywheel/clutch assembly Jon
Repeatedly dropping the clutch at 6 or 7K revs on the start line at a sprint couse applies lots of stress
Presumably a 200 mill clutch is not as strong as a 212 mill one
Re: 4A-GE & 4A-GZE Crankshaft & Flywheel
I would presume not considering Toyota changed it. However my guess is that Toda have simply applied the maximum friction surface area possible to their product; it's not like they are going to go to the effort of R&D'ing something which won't stand up to abuse, Toda stuff is aimed at circuit use. If it measures at 218mm it's a 218mm clutch (/fly), not a 200

I agree with everything you're saying there Jon
Looks like I have a really 218mm clutch
Have emailed Toda-Europe with the part number of the fly
They say it "should be the correct part number" for my engine
It was just the part number ending in 200 that made me feel uneasy

Re: 4A-GE & 4A-GZE Crankshaft & Flywheel
The Fidanza is 3.7kgs and the Toda is 4.4kgs - are you really going to notice the 0.7kgs?

Stock is 7 Kg Alex
Reasonable saveing
Toda do a 3.7 Kg fly ( for the pre 85 Mk1)

The toda is steel not aluminium so will be stronger.
Nice to see your keeping the 'std car' as per your regs

I've had the parts for quite a while
Now's my chance to fit them Tim
